[ Next | Top of file ] Manuscript Completed: October 1998 Prepared by Division of Industrial and Medical Nuclear Safety Abstract
[ Prev | Next | Top of file ] As part of its redesign of the materials licensing process, the Nuclear Regulatory Commission (NRC) is consolidating and updating numerous guidance documents into a single comprehensive repository as described in NUREG-1539, "Methodology and Findings of the NRC's Materials Licensing Process Redesign," dated April 1996, and draft NUREG-1541, "Process and Design for Consolidating and Updating Materials Licensing Guidance," dated April 1996. NUREG-1556, Vol. 4, "Consolidated Guidance about Materials Licenses: Program-Specific Guidance about Fixed Gauges Licenses," dated October 1998, is the fourth program-specific guidance developed for the new process and is intended for use by applicants, licensees, and NRC staff and will also be available to Agreement States. This document supersedes the guidance found in Draft Regulatory Guide and Value/Impact Statement, FC 404-4, "Guide for the Preparation of Applications for Licenses for the Use of Sealed Sources and Nonportable Gauging Devices," dated January 1985, in NMSS Policy and Guidance Directive (P&GD), FC 85-4, "Standard Review Plan for Applications for Use of Sealed Sources and Nonportable Gauging Devices," dated February 6, 1985, and in NMSS P&GD, FC 85-8, Revision (Rev.) 1, "Licensing of Fixed Gauges and Similar Devices," dated June 29, 1988. This final report takes a more risk-informed, performance-based approach to licensing fixed gauges, and reduces the information (amount and level of detail) needed to support an application to use these devices. It incorporates many suggestions received during the comment period on draft NUREG-1556, Vol. 4. When published, this final report should be used in preparing fixed gauge license applications. NRC staff will use this final report in reviewing these applications. Figures

[ Prev | Next | Top of file ] The United States Nuclear Regulatory Commission (NRC) is using Business Process Redesign (BPR) techniques to redesign its materials licensing process. This effort is described in NUREG-1539, "Methodology and Findings of the NRC's Materials Licensing Process Redesign," dated April 1996. A critical element of the new process is consolidating and updating numerous guidance documents into a NUREG-series of reports. Below is a listing of volumes currently included in the NUREG-1556 series: "Consolidated Guidance About Materials Licenses":
The current document (NUREG-1556, Vol. 4, "Consolidated Guidance about Materials Licenses: Program-Specific Guidance about Fixed Gauges," dated October 1998) is the fourth program-specific guidance developed for the new process. It is intended for use by applicants, licensees, NRC license reviewers, and other NRC personnel. It supersedes the guidance for applicants and licensees previously found in Draft Regulatory Guide and Value/Impact Statement, FC 404-4, "Guide for the Preparation of Applications for Licenses for the Use of Sealed Sources in Nonportable Gauging Devices," dated January 1985, and the guidance for licensing staff previously found in P&GD, FC 85-4, "Standard Review Plan for Applications for the Use of Sealed Sources in Nonportable Gauging Devices," dated February 6, 1985, P&GD, FC 85-8, Rev. 1, "Licensing of Fixed Gauges and Similar Devices," dated June 29, 1988, and the documents marked with an asterisk (*) in Appendix Q. NUREG-1556, Vol. 4 incorporates suggestions submitted during the comment period on draft NUREG-1556, Vol. 4. See the Addendum for summaries of comments, staff responses, and other changes. This report takes a risk-informed, performance-based approach to licensing fixed gauges, i.e., it reduces the amount of information needed from an applicant seeking to possess and use a relatively safe device. These fixed gauges containing sealed sources of radioactive material incorporate features engineered to enhance their safety. NRC's considerable experience with these licensees indicates that radiation exposures to workers are generally low, if workers follow basic safety procedures, and the gauges operate as designed. A team composed of NRC staff from headquarters and regional offices drafted this document, drawing on their collective experience in radiation safety in general and as specifically applied to fixed gauges. A representative of NRC's Office of the General Counsel provided a legal perspective. NUREG-1556, Vol. 4, "Consolidated Guidance about Materials Licenses: Program-Specific Guidance about Fixed Gauges," dated October 1998, represents a step in the transition from the current paper-based process to the new electronic process. This document is available on the Internet at the following uniform resource locator (URL): <http://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr1556/v4/index.html> The performance-based approach in NUREG-1556, Vol. 4, gives licensees greater flexibility than previously permitted under licenses based on applications prepared according to Draft Regulatory Guide and Value/Impact Statement, FC 404-4, "Guide for the Preparation of Applications for Licenses for the Use of Sealed Sources in Nonportable Gauging Devices," dated January 1985. This guidance document permits licensees to make more changes in their radiation safety program without amending their licenses, thus reducing the regulatory burden on licensees and the NRC staff. Accordingly, existing fixed gauge licensees have the option of submitting a complete application using NUREG-1556, Vol. 4, at the time that they file an amendment request. Licensees choosing this option should incorporate the requested change into the complete application, submit it with the appropriate amendment fee, and indicate that the complete revision is an amendment request to take advantage of the new guidance. When the staff has reviewed the request and resolved any outstanding issues, the staff will amend the license without changing the expiration date. Licensees wishing to renew their licenses should submit a complete application according to NUREG-1556, Vol. 4. The staff's action will be similar to that described for amendments, but will include an extension of the license's expiration date. By following this procedure, the staff expects all existing fixed gauge licenses to be converted to the more performance-based format within a few years. This report describes and makes available to the public information on: methods acceptable to the NRC staff for implementing specific parts of the Commission's regulations; techniques the staff uses in evaluating applications, including specific problems or postulated accidents; and data the NRC staff needs to review applications for licenses. NUREG-1556, Vol. 4, "Consolidated Guidance about Materials Licenses: Program-Specific Guidance about Fixed Gauges," dated October 1998, is not a substitute for NRC regulations, and compliance is not required. The approaches and methods described in this report are provided for information only. Methods and solutions different from those described in this report will be acceptable if they provide a basis for the staff to make the determinations needed to issue or continue a license. __________________________________ Acknowledgments

1 Purpose of Report
[ Prev | Next | Top of file ] This report provides guidance to an applicant in preparing a fixed gauge license application as well as NRC criteria for evaluating a fixed gauge license application. It is not intended to address the research and development of fixed gauges or the commercial aspects of manufacturing, distribution, and service of such devices. Within this document, the phrases or terms, "fixed gauge," "gauging devices," or "gauges" are used interchangeably. This report addresses a variety of radiation safety issues associated with fixed gauges of many designs. Figure 1.1 is a cutaway diagram of a typical fixed gauge showing basic design features. Figure 1.2 illustrates various designs of fixed gauges based, in part, on their intended use and the location of the radioactive source within the gauges. Typically gauges are used for process control (e.g., to measure the thickness of paper, the density of coal, the level of material in vessels and tanks, and volumetric flow rate). Because of differences in design, manufacturers provide appropriate instructions and recommendations for proper operation and maintenance. In addition, with gauges of varying designs, the sealed sources may be oriented in different locations within the devices, resulting in different radiation safety problems. Figure 1.1 Fixed Gauge Basic Design Features. Cutaway of a typical fixed gauge diagraming the basic design features: the source, source holder, detector, shutter, shutter control or on-off mechanism, and shielding. Figure 1.2 Where is the Radioactive Source? The wide variety of fixed gauge designs results in different radiation safety considerations. This report identifies the information needed to complete NRC Form 313 (Appendix A), "Application for Material License," for the use of sealed sources in fixed gauges. The information collection requirements in Title 10, Code of Federal Regulations, Part 30 (10 CFR Part 30) and NRC Form 313 have been approved under the Office of Management and Budget (OMB) Clearance Nos. 3150-0017 and 3150-0120, respectively. The format within this document for each item of technical information is as follows:
Notes and References are self-explanatory and may not be found for each item on NRC Form 313. Appendix B provides a convenient format to respond to items 5 through 11 on NRC Form 313 (Appendix A) since the form does not have sufficient space for applicants to provide full responses to these items. For streamlined handling of fixed gauge applications in the new materials licensing process, use Appendix B to provide supporting information, attach it to NRC Form 313, and submit them to NRC. Otherwise, as indicated on NRC Form 313, the answers to items 5 through 11 are to be provided on separate sheets of paper and submitted with the completed NRC Form 313. Appendix C contains information needed for transfer of control. Appendix D is a checklist that NRC staff uses to review applications and applicants can use to check for completeness. Appendix E contains a sample SSD Registration Certificate. Appendixes F through P contain additional information on various radiation safety topics. Appendix Q is a sample fixed gauge license; it contains the conditions most often found on these licenses, although not all licenses will have all conditions. Appendix R contains a list of all documents used to develop this NUREG (NUREG-1556, Vol. 4). The Addendum contains the comments received on draft NUREG-1556, Vol. 4 and NRC staff's response to each comment. In this document, dose or radiation dose means absorbed dose, dose equivalent, effective dose equivalent (EDE), committed dose equivalent (CDE), committed effective dose equivalent (CEDE), or total effective dose equivalent (TEDE). These terms are defined in 10 CFR Part 20. Rem, and its SI equivalent Sievert (1 rem = 0.01 Sievert (Sv)), are used to describe units of radiation exposure or dose. This is done because 10 CFR Part 20 sets dose limits in terms of rem, not rad or roentgen (R). When the sealed sources used in gauges emit beta and gamma rays, for practical reasons, we are assuming that 1 R = 1 rad = 1 rem. Less common are sealed sources used in gauges that emit neutrons or alpha particles. For neutron and alpha emitting sealed sources, 1 rad is not equal to 1 rem. Determination of dose equivalent (rem) from absorbed dose (rad) from neutrons and alpha particles requires the use of an appropriate quality factor (Q) value. Q values are used to convert absorbed dose (rad) to dose equivalent (rem). Q values for neutrons and alpha particles are addressed in the Tables 1004(b).1 and 2 in 10 CFR §20.1004. 2 Agreement States
[ Prev | Next | Top of file ] Certain states, called Agreement States (see Figure 2.1), have entered into agreements with the NRC that give them the authority to license and inspect byproduct, source, or special nuclear materials used or possessed within their borders. A current list of Agreement States (including names, addresses, and telephone numbers of responsible officials) may be obtained upon request from NRC's Regional Offices. Any applicant other than a Federal agency who wishes to possess or use licensed material in one of these Agreement States needs to contact the responsible officials in that State for guidance on preparing an application; file these applications with State officials, not with the NRC. In general, NRC's materials licensees who wish to conduct operations at temporary job sites in an Agreement State should contact that State's radiation control program office for information about State regulations. To ensure compliance with Agreement State reciprocity requirements, a licensee should request authorization well in advance of scheduled use. In the special situation of work at Federally-controlled sites in Agreement States, it is necessary to know the jurisdictional status of the land in order to determine whether NRC or the Agreement State has regulatory authority. NRC has regulatory authority over land determined to be "exclusive Federal jurisdiction," while the Agreement State has jurisdiction over non-exclusive Federal jurisdiction land. Licensees are responsible for finding out, in advance, the jurisdictional status of the specific areas where they plan to conduct licensed operations. NRC recommends that licensees ask their local contact for the Federal agency controlling the site (e.g., contract officer, base environmental health officer, district office staff) to help determine the jurisdictional status of the land and to provide the information in writing, so that licensees can comply with NRC or Agreement State regulatory requirements, as appropriate. Additional guidance on determining jurisdictional status is found in All Agreement States Letter, SP-96-022, dated February 16, 1996, which is available as indicated below. Table 2-1 provides a quick way to check on which agency has regulatory authority. Table 2.1 Who Regulates the Activity?

[ Prev | Next | Top of file ] The NRC recognizes that effective radiation safety program management is vital to achieving safe and compliant operations. NRC also believes that consistent compliance with its regulations provides reasonable assurance that licensed activities will be conducted safely. NRC also believes that effective management will result in increased safety and compliance.
To ensure adequate management involvement, a duly authorized management representative must sign the submitted application acknowledging management's commitments and responsibility for the following:
For information on NRC inspection, investigation, enforcement, and other compliance programs, see the current version of "General Statement of Policy and Procedures for NRC Enforcement Actions," NUREG-1600, and Inspection Procedure (IP) 87110, Appendix A, "Industrial/Academic/Research Inspection Field Notes." These documents are available electronically at <http://www.nrc.gov>. For hard copies of NUREG-1600 and IP 87110, see the Notice of Availability (on the inside front cover of this report). 4 Applicable Regulations
[ Prev | Next | Top of file ] It is the applicant's or licensee's responsibility to have up-to-date copies of applicable regulations, read them, and abide by each applicable regulation. The following Parts of 10 CFR Chapter I contain regulations applicable to fixed gauges:

You may also contact the GPO electronically at <http://www.gpo.gov> 5 How to File
[ Prev | Next | Top of file ] 5.1 Paper Application
[ Prev | Next | Top of file ] Applicants for a materials license should do the following:
All license applications will be available for review by the general public in NRC's Public Document Rooms. If it is necessary to submit proprietary information, follow the procedure in 10 CFR 2.790. Failure to follow this procedure could result in disclosure of the proprietary information to the public or substantial delays in processing the application. Employee personal information, i.e., home address, home telephone number, social security number, date of birth, radiation dose information, should not be submitted unless specifically requested by NRC. As explained in the Foreword to this document, NRC's new licensing process will be faster and more efficient, in part, through acceptance and processing of electronic applications at some future date. NRC will continue to accept paper applications. However, these will be scanned and put through an optical character reader to convert them to electronic format. To ensure a smooth transition, applicants are requested to follow these suggestions:
5.2 Electronic Application
[ Prev | Next | Top of file ] As the electronic licensing process develops, it is anticipated that NRC may provide mechanisms for filing applications via diskettes or CD-ROM, and through the Internet. Additional filing instructions will be provided as these new mechanisms become available. The existing paper process will be used until the electronic process is available. 6 Where to File
[ Prev | Next | Top of file ] Applicants wishing to possess or use licensed material in any State or U.S. territory or possession subject to NRC jurisdiction must file an application with the NRC Regional Office for the locale in which the material will be possessed and/or used. Figure 2.1 shows NRC's four Regional Offices and their respective areas for licensing purposes and identifies Agreement States. In general, applicants wishing to possess or use licensed material in Agreements States must file an application with the Agreement State, not NRC. However, if work will be conducted at Federally controlled sites in Agreement States, applicants must first determine the jurisdictional status of the land in order to determine whether NRC or the Agreement State has regulatory authority. See the section on "Agreement States" for additional information. 7 License Fees
[ Prev | Next | Top of file ] Each application for which a fee is specified, including applications for new licenses and license amendments, must be accompanied by the appropriate fee. Refer to 10 CFR 170.31 to determine the amount of the fee. NRC will not issue the new license prior to fee receipt. Once technical review has begun, no fees will be refunded; application fees will be charged regardless of the NRC's disposition of an application or the withdrawal of an application. Most NRC licensees are also subject to annual fees; refer to 10 CFR 171.16. Consult 10 CFR 171.11 for additional information on exemptions from annual fees and 10 CFR 171.16(c) on reduced annual fees for licensees that qualify as "small entities." Direct all questions about NRC's fees or completion of Item 12 of NRC Form 313 (Appendix A) to the Office of the Chief Financial Officer at NRC Headquarters in Rockville, Maryland, (301) 415-7554. You may also call NRC's toll free number (800) 368-5642 and then ask for extension 415-7554. 8 Contents of an Application
[ Prev | Next | Top of file ] The following comments apply to the indicated items on NRC Form 313 (Appendix A). 8.1 Item 1: License Action Type
[ Prev | Next | Top of file ] THIS IS AN APPLICATION FOR (Check appropriate item):
Check box A for a new license request. 8.2 Item 2: Applicant's Name and Mailing Address
[ Prev | Next | Top of file ] List the legal name of the applicant's corporation or other legal entity with direct control over use of the radioactive material; a division or department within a legal entity may not be a licensee. An individual may be designated as the applicant only if the individual is acting in a private capacity and the use of the radioactive material is not connected with employment in a corporation or other legal entity. Provide the mailing address where correspondence should be sent. A post office box number is an acceptable mailing address. Notify NRC of changes in mailing address; these changes do not require a fee. Note: NRC must be notified before control of the license is transferred or bankruptcy proceedings have been initiated; see below for more details. NRC Information Notice (IN) 97-30, "Control of Licensed Material during Reorganizations, Employee-Management Disagreements, and Financial Crises," dated June 3, 1997, discusses the potential for the security and control of licensed material to be compromised during periods of organizational instability. Timely Notification of Transfer of Control Regulations: 10 CFR 30.34(b). Criteria: Licensees must provide full information and obtain NRC's prior written consent before transferring control of the license, or, as some licensees call it, "transferring the license." Discussion: Transfer of control may be the result of mergers, buyouts, or majority stock transfers. Although it is not NRC's intent to interfere with the business decisions of licensees, it is necessary for licensees to obtain prior NRC written consent before the transaction is finalized. This is to ensure the following:
Response from Applicant: None from an applicant for a new license; Appendix C, excerpted from IN 89-25, Revision 1, "Unauthorized Transfer of Ownership or Control of Licensed Activities," dated December 7, 1994, identifies the information to be provided about transfers of control. References: See Notice of Availability (on the inside front cover of this report) to obtain copies of IN 89-25, Revision 1, "Unauthorized Transfer of Ownership or Control of Licensed Activities," dated December 7, 1994, and IN 97-30, "Control of Licensed Material during Reorganizations, Employee-Management Disagreements, and Financial Crises," dated June 3, 1997. Notification of Bankruptcy Proceedings Regulations: 10 CFR 30.34(h). Criteria: Immediately following filing of voluntary or involuntary petition for bankruptcy for or against a licensee, the licensee must notify the appropriate NRC Regional Administrator, in writing, identifying the bankruptcy court in which the petition was filed and the date of filing. Discussion: Even though a licensee may have filed for bankruptcy, the licensee remains responsible for all regulatory requirements. NRC needs to know when licensees are in bankruptcy proceedings in order to determine whether all licensed material is accounted for and adequately controlled and whether there are any public health and safety concerns (e.g., contaminated facility). NRC shares the results of its determinations with other involved entities (e.g., trustee) so that health and safety issues can be resolved before bankruptcy actions are completed. Response from Applicant: None at time of application for a new license. Generally, licensees should notify NRC within 24 hours of filing a bankruptcy petition. References: INs are available in the "Reference Library" on NRC's Home Page at <http://www.nrc.gov.> For hard copies, see the Notice of Availability (on the inside front cover of this report). 8.3 Item 3: Address(es) Where Licensed Material Will Be Used or Possessed
[ Prev | Next | Top of file ] Specify the street address, city, and state or other descriptive address (such as on Highway 10, 5 miles east of the intersection of Highway 10 and State Route 234, Anytown, State) for each facility. The descriptive address should be sufficient to allow an NRC inspector to find the facility location. A Post Office Box address is not acceptable.
An NRC-approved license amendment is required before locating a gauge at an address not already listed on the license, whether that gauge is an additional unit or a relocation of an existing unit. For information on conducting operations at temporary job sites (i.e., locations where work is conducted for limited periods of time, refer to the section in this report called "Fixed Gauges Used at Temporary Job Sites." That section offers examples of operations where fixed gauges might be used at temporary job sites and gives information which should be provided to the NRC to support a request for these operations.
Note: As discussed later in the section "Financial Assurance and Record Keeping for Decommissioning," licensees do need to maintain permanent records on where licensed material was used or stored while the license was in force. This is important for making future determinations about the release of these locations for unrestricted use (e.g., before the license is terminated). For fixed gauge licensees, acceptable records are sketches or written descriptions of specific locations where each gauge was used or stored and any information relevant to damaged devices or leaking radioactive sources. 8.4 Item 4: Person to Be Contacted about this Application
[ Prev | Next | Top of file ] Identify the individual who can answer questions about the application and include his or her telephone number. This is typically the proposed radiation safety officer, unless the applicant has named a different person as the contact. The NRC will contact this individual if there are questions about the application. Notify NRC if the contact person or his or her telephone number changes so that NRC can contact the applicant or licensee in the future with questions, concerns, or information. This notice is for "information only" and does not require a license amendment or a fee.
8.5 Item 5: Radioactive Material
[ Prev | Next | Top of file ] 8.5.1 Sealed Sources and DevicesRegulations: 10 CFR 30.32(g), 10 CFR 30.33(a)(2), 10 CFR 32.210. Criteria: Applicants must provide the manufacturer's or distributor's name and model number for each requested sealed source and device. Licensees will be authorized to possess and use only those sealed sources and devices specifically approved or registered by NRC or an Agreement State. Discussion: NRC or an Agreement State performs a safety evaluation of fixed gauges before authorizing a manufacturer or distributor to distribute the gauges to specific licensees. The safety evaluation is documented in a Sealed Source and Device (SSD) Registration Certificate. Before the SSD registration process was formalized, some older gauges may not have been evaluated in a separate document, but were specifically approved on a license. Licensees can continue to use these gauges that are specifically listed on their licenses. Some examples of fixed gauges are shown in Figure 8.1. Figure 8.1 Examples of Several Different Types of Fixed Gauges. Consult with the proposed manufacturer or distributor to ensure that requested sources and devices are compatible and conform to the sealed source and device designations registered with NRC or an Agreement State. Licensees may not make any changes to the sealed source, device, or source/device combination that would alter the description or specifications from those indicated in the respective registration certificates, without obtaining NRC's prior permission in a license amendment. Such changes may necessitate a custom registration review, increasing the time needed to process a licensing action. SSD Registration Certificates contain sections on "Conditions of Normal Use" and "Limitation and Other Considerations of Use." These sections may include limitations derived from conditions imposed by the manufacturer or distributor, by particular conditions of use that would reduce radiation safety of the device, or by circumstances unique to the sealed source or device. For example, working life of the device or appropriate temperature and other environmental conditions may be specified. Except as specifically approved by NRC, licensees are required to use gauges according to their respective SSD Registration Certificates. Accordingly, applicants may want to obtain a copy of the certificate and review it with the manufacturer or distributor or with NRC or the issuing Agreement State to ensure that it correctly reflects the radiation safety properties of the source or device. See Appendix E for an example of a fixed gauge SSD Registration Certificate. Response from Applicant:
Note: For information on SSD registration certificates, contact the Registration Assistant by calling NRC's toll free number (800) 368-5642 and then asking for extension 415-7217. For more information about the SSD registration process, see the current version of NUREG-1556, Vol. 3, "Consolidated Guidance About Materials Licenses: Applications for Sealed Source and Device Evaluation and Registration." It is available electronically in the "Reference Library" at <http://www.nrc.gov>; for a paper copy, see the Notice of Availability (on the inside front cover of this report). 8.5.2 Financial Assurance and Recordkeeping for DecommissioningRegulations: 10 CFR 30.34(b), 10 CFR 30.35. Criteria: Fixed gauge licensees authorized to possess sealed sources containing radioactive material in excess of the limits specified in 10 CFR 30.35(b) and (d) must provide evidence of financial assurance for decommissioning. Even if no financial assurance is required, licensees are required to maintain, in an identified location, decommissioning records related to structures and equipment where gauges are used or stored and to leaking sources. Pursuant to 10 CFR 30.35(g), licensees must transfer these records important to decommissioning to either of the following:
The appropriate NRC regional office before the license is terminated. Discussion: The requirements for financial assurance are specific to the types and quantities of byproduct material authorized on a license. Most fixed gauge applicants and licensees do not need to take any action to comply with the financial assurance requirements because their total inventory of licensed material does not exceed the thresholds in 10 CFR 30.35(b) and (d). The thresholds for typical radionuclides used for fixed gauge sealed sources are shown in Table 8.1. Table 8.1 Examples of Minimum Inventory Quantities Requiring Financial Assurance
A licensee would need to possess hundreds of gauges before the financial assurance requirements would apply. Since the standard gauge license does not specify the maximum number of gauges that a licensee may possess (allowing flexibility in obtaining additional gauges specifically authorized by the license as needed without amending its license), it contains a condition requiring the licensee to limit its possession of fixed gauges to quantities not requiring financial assurance. Applicants and licensees desiring to possess gauges exceeding the threshold amounts must submit evidence of financial assurance. Applicants requesting more than one radionuclide may determine whether financial assurance for decommissioning is required by calculating, for each radionuclide possessed, the ratio between the activity possessed, in curies, and the radionuclide's threshold activity requiring financial assurance, in curies. If the sum of such ratios for all of the radionuclides possessed exceeds "1" (i.e., "unity"), then applicants must submit evidence of financial assurance for decommissioning. The same regulation also requires that licensees maintain records important to decommissioning in an identified location. All fixed gauge licensees need to maintain records of structures and equipment where each gauge was used or stored. As-built drawings with modifications of structures and equipment shown as appropriate fulfill this requirement. If drawings are not available, licensees shall substitute appropriate records (e.g., a sketch of the room or building or a narrative description of the area) concerning the specific areas and locations. If no records exist regarding structures and equipment where gauges were used or stored, licensees shall make all reasonable efforts to create such records based upon historical information (e.g. employee recollections). In addition, if fixed gauge licensees have experienced unusual occurrences (e.g., leaking sources, other incidents that involve spread of contamination), they also need to maintain records about contamination that remains after cleanup or that may have spread to inaccessible areas.
Response from Applicant: No response is needed from most applicants. If financial assurance is required, submit the documentation required under 10 CFR 30.35. RG 3.66, "Standard Format and Content of Financial Assurance Mechanisms Required for Decommissioning Under 10 CFR Parts 30, 40, 70, and 72," dated June 1990, contains approved wording for each of the mechanisms authorized by the regulation to guarantee or secure funds except for the Statement of Intent for Government licensees.
References: See Notice of Availability (on the inside front cover of this report) to obtain copies of RG 3.66, "Standard Format and Content of Financial Assurance Mechanisms Required for Decommissioning Under 10 CFR Parts 30, 40, 70, and 72," dated June 1990, and P&GD FC 90-2, Revision 1, "Standard Review Plan for Evaluating Compliance with Decommissioning Requirements," dated April 30, 1991. 8.6 Item 6: Purpose(s) for Which Licensed Material Will Be UsedRegulations: 10 CFR 30.33(a)(1). Criteria: Proposed purpose is authorized by the Atomic Energy Act of 1954, as amended. Gauges should be used only for the purposes for which they were designed, according to the manufacturer's or distributor's recommendations and instructions, as specified in an approved SSD Registration Certificate, and as authorized on an NRC license. Discussion: Uses other than those listed in the SSD Registration Certificate require review and approval by the NRC or an Agreement State. Requests to use fixed gauges for purposes not listed in the SSD Registration Certificate will be reviewed on a case-by-case basis. Applicants need to submit sufficient information to demonstrate that the proposed use will not compromise the integrity of the source or source shielding, or other radiation safety-critical components of the device. NRC will evaluate the radiation safety program for each type and use of gauge requested.
Response from Applicant: Provide either of the following:

8.7 Item 7: Individual(s) Responsible for Radiation Safety Program and Their Training Experience
[ Prev | Next | Top of file ] 8.7.1 Radiation Safety Officer (RSO)Regulations: 10 CFR 30.33(a)(3). Criteria: Radiation Safety Officers (RSOs) must have adequate training and experience. Successful completion of training of one of the following is evidence of adequate training and experience.
Additional training is required for RSOs of programs that perform non-routine operations. This includes repairs involving or potentially affecting components related to the radiological safety of the gauge (e.g., the source, source holder, source drive mechanism, shutter, shutter control, or shielding) and any other activities during which personnel could receive radiation doses exceeding NRC limits (e.g., installation, initial radiation survey, gauge relocation, and removal of the gauge from service). See "Radiation Safety Program - Maintenance" in this report and Appendix N, "Non Routine Operations." Discussion: The person responsible for the radiation protection program is called the Radiation Safety Officer (RSO). The RSO needs independent authority to stop operations that he or she considers unsafe. He or she must have sufficient time and commitment from management to fulfill certain duties and responsibilities to ensure that radioactive materials are used in a safe manner. Typical RSO duties are illustrated in Figure 8.2 and described in Appendix F. NRC requires the name of the RSO on the license to ensure that licensee management has always identified a responsible, qualified person and that the named individual knows of his or her designation as RSO.

8.7.2 Authorized UsersRegulations: 10 CFR 30.33(a)(3). Criteria: Authorized users (AUs) must have adequate training and experience. Successful completion of one of the following is evidence of adequate training and experience:
Applicants requesting to perform non-routine operations such as installation, initial radiation survey, repair, and maintenance of components related to the radiological safety of the gauge, gauge relocation, replacement and disposal of sealed sources, alignment, or removal of a gauge from service, must provide additional training. See the section in this report titled "Radiation Safety Program - Maintenance" and Appendix N. Discussion: An AU is a person whose training and experience meet NRC criteria, who is named either explicitly or implicitly on the license, and who uses or directly supervises the use of licensed material. AUs must ensure the proper use, security, and routine maintenance of fixed gauges containing licensed material. AUs must attend the training and instruction given at the time of installation or receive equivalent training and instruction. An AU is considered to be supervising the use of licensed material when he or she directs personnel in operations involving the material. Although the AU may delegate specific tasks to supervised users (e.g., maintaining records), he or she is still responsible for safe use of licensed material. Response from Applicant: Provide either of the following:
OR
Note: Alternative responses will be evaluated using the criteria listed above. 8.8 Item 8: Training for Individuals Who in the Course of Employment Are Likely to Receive Occupational Doses of Radiation in Excess of 1 Msv (100 Mrem) in a Year (Occupationally Exposed Workers) and Ancillary Personnel
[ Prev | Next | Top of file ] Regulations: 10 CFR 19.11, 10 CFR 19.12, 10 CFR 19.13, 10 CFR 20.1801, 10 CFR 20.1802, 10 CFR 30.7, 10 CFR 30.9, 10 CFR 30.10, 10 CFR 30.33. Criteria: Individuals who in the course of employment are likely to receive occupational doses of radiation in excess of 1 mSv (100 mrem) in a year must receive training according to 10 CFR 19.12. The extent of this training must be commensurate with potential radiological health protection problems present in the work place. Discussion: Licensees need to perform a prospective evaluation to determine radiation doses likely to be received by different individuals or groups. AUs, and individuals performing installations, relocations, non-routine maintenance, or repairs would be most likely to receive doses in excess of 1 mSv (100 mrem) in a year. See the previous section for a discussion of training and experience for Aus. Licensee personnel who work in the vicinity of a fixed gauge but do not use gauges (ancillary staff) are not required to have radiation safety training as long as they are not likely to receive 1 mSv (100 mrem) in a year. However, to minimize potential radiation exposure when ancillary staff are working in the vicinity of a fixed gauge, it is prudent for them to work under the supervision and in the physical presence of an AU or to be provided some basic radiation safety training. Such ancillary staff should be informed of the nature and location of the gauge and the meaning of the radiation symbol, and should be instructed not to touch the gauge and to keep away from it as much as their work permits. Some ancillary staff, although not likely to receive doses over 1 mSv (100 mrem), should receive training to ensure adequate security and control of licensed material. Licensees may provide these individuals with training commensurate with their assignments in the vicinity of the gauge, to ensure the control and security of licensed material. Response from Applicant: The applicant's training program, for individuals who in the course of employment are likely to receive occupational doses of radiation in excess of 1 mSv (100 mrem) in a year (occupationally exposed workers) and ancillary personnel, will be examined during inspections, but should not be submitted in the license application. 8.9 Item 9: Facilities and Equipment
[ Prev | Next | Top of file ] Regulations: 10 CFR 30.33(a)(2), 10 CFR 32.210. Criteria: Facilities and equipment must be adequate to protect health and to minimize danger to life or property. This may be demonstrated by the following:
Discussion: Fixed gauges incorporate many engineering features to protect the user from unnecessary radiation exposure in a wide variety of environments. Fixed gauges may be located in harsh environments involving variables such as pressure, vibration, mounting height/method, temperature, humidity, air quality, corrosive atmospheres, corrosive chemicals including process materials and cleaning agents, possible impact or puncture conditions, and fire, explosion, and flooding potentials. Applicants need to consult the sections on the SSD Registration Certificate, "Conditions of Normal Use" and "Limitations and/or Other Considerations of Use" to determine the appropriate gauge for a location. In those instances when a proposed location is not consistent with the SSD Registration Certificate, the applicant may ask the source or device manufacturer or distributor to request an amendment to modify the SSD Registration Certificate to include the new conditions. If the manufacturer or distributor does not request an amendment, the applicant must provide the NRC with specific information demonstrating that the proposed new conditions will not impact the safety or integrity of the source or device. Response from Applicant: Provide one of the following:
OR

[ Prev | Next | Top of file ] 8.10.1 Audit ProgramRegulations: 10 CFR 20.1101, 10 CFR 20.2102. Criteria: Licensees must review the content and implementation of their radiation protection programs at intervals not to exceed 12 months to ensure the following:
Discussion: Appendix H contains a suggested audit program that is specific to the use of fixed gauges and is acceptable to NRC. All areas indicated in Appendix H may not be applicable to every licensee and all items may not need to be addressed during each audit. For example, licensees do not need to address areas which do not apply to their activities, and activities which have not occurred since the last audit need not be reviewed at the next audit. Currently the NRC's emphasis in inspections is to perform actual observations of work in progress. As a part of their audit programs, applicants should consider performing unannounced audits of fixed gauge users to determine if, for example, Operating and Emergency Procedures are available and are being followed, etc. It is essential that once identified, problems be corrected comprehensively and in a timely manner; IN 96-28, "Suggested Guidance Relating to Development and Implementation of Corrective Action," provides guidance on this subject. The NRC will review the licensee's audit results and determine if corrective actions are thorough, timely, and sufficient to prevent recurrence. If violations are identified by the licensee and these steps are taken, the NRC will normally exercise discretion and may elect not to cite a violation. The NRC's goal is to encourage prompt identification and prompt, comprehensive correction of violations and deficiencies. For additional information on NRC's use of discretion on issuing violations, refer to the current version of NUREG-1600, "General Statement of Policy and Procedures for NRC Enforcement Actions." Licensees must maintain records of audits and other reviews of program content and implementation for 3 years from the date of the record. NRC has found audit records that contain the following information to be acceptable: date of audit, name of person(s) who conducted audit, persons contacted by the auditor(s), areas audited, audit findings, corrective actions, and follow-up. Response from Applicant: The applicant's program for reviewing the content and implementation of its radiation protection program will be examined during inspections, and should not be submitted in the license application.

Criteria: Licensees must possess, or have access to, radiation monitoring instruments which are necessary to protect health and minimize danger to life or property. Instruments used for quantitative radiation measurements must be calibrated periodically for the radiation measured. Discussion: Usually it is not necessary for fixed gauge licensees to possess a survey meter. However, surveys according to 10 CFR 20.1501 will be required if an applicant plans to conduct non-routine operations. This includes installation, initial radiation surveys, relocation, removal from service, dismantling, alignment, replacement, disposal of the sealed source, and non-routine maintenance and repair of components related to the radiological safety of the gauge. Because some of these operations may increase the risk of radiation exposure, individuals performing these operations should be carefully monitored with a survey meter. Such survey meters should be properly calibrated. Proper calibration is particularly important for initial surveys since the results can be used as a basis for public dose estimates. For those licensees requesting authorization to calibrate their own survey instruments, Appendix I contains calibration procedures acceptable to the NRC. Licensees who perform surveys pursuant to 10 CFR 20.1501 must possess a survey meter that
By the instrument manufacturer or person specifically authorized by the NRC or an Agreement State Since many fixed gauge licensees are not required to possess a survey meter, applicants should preplan how they will obtain assistance in performing a radiation survey in the event of an emergency (e.g., obtain a survey instrument from hospitals, universities, other NRC or Agreement State licensees, or local emergency response organization). It is important to determine as soon as possible after an incident, by the use of a radiation survey meter, whether the shielding and source are intact. For those licensees using gauges containing only beta, neutron or alpha-emitting radionuclides, specialized survey instruments may be required. Response from Applicant: Provide one of the following:

Discussion: As illustrated in Figure 8.3, licensed materials must be tracked from "cradle to grave" in order to ensure gauge accountability, identify when gauges could be lost, stolen, or misplaced, and ensure that possession limits listed on the license are not exceeded. Significant problems can arise from failure to ensure the accountability of gauges. See IN 88-02, "Lost or Stolen Gauges," dated February 2, 1988. Figure 8.3 Material Receipt and Accountability. Licensees must maintain records of receipt, transfer, and disposal and conduct semiannual physical inventories. Receipt, transfer, and disposal records must be maintained for the times specified in Table 8-2. Typically, these records contain the following types of information:

Figure 8.4 Annual Dose Limits for Occupationally Exposed Adults. Discussion: Under conditions of routine use, the typical fixed gauge user does not require a personnel monitoring device (dosimetry). A gauge user also does not require dosimetry when proper emergency procedures are used. Appendix J provides guidance on performing a prospective evaluation demonstrating that fixed gauge users are not likely to exceed 10% of the limits as shown in Figure 8.4 and thus, are not required to have personnel dosimetry. Individuals who perform non-routine operations such as installation, initial radiation survey, repair, and maintenance of components related to the radiological safety of the gauge, gauge relocation, replacement, and disposal of sealed sources, alignment, or removal of a gauge from service are more likely to exceed 10% of the limits as shown in Figure 8.4. Applicants may be required to provide dosimetry (whole body and perhaps extremity monitors) to individuals performing such services or must perform a prospective evaluation demonstrating that unmonitored individuals performing such non-routine operations are not likely to receive, in one year, a radiation dose in excess of 10% of the allowable limits as shown in Figure 8.4. When personnel monitoring is needed, most licensees use either film badges or thermoluminescent dosimeters (TLDs) that are supplied by a NVLAP-approved processor. The exchange frequency for film badges is usually monthly due to technical concerns about film fading. The exchange frequency for TLDs is usually quarterly. Applicants should verify that the processor is NVLAP-approved. Consult the NVLAP-approved processor for its recommendations for exchange frequency and proper use.
