|NRC INFORMATION NOTICE 99-18:||UPDATE ON NRC's YEAR 2000 ACTIVITIES FOR MATERIALS LICENSEES AND FUEL CYCLE LICENSEES AND CERTIFICATE HOLDERS|
All material and fuel cycle licensees and certificate holders.
The U.S. Nuclear Regulatory Commission (NRC) is issuing this information notice (IN) to update addressees regarding NRC's Year 2000 (Y2K) activities and provide sources of Y2K information. It is expected that recipients will review this information for applicability to their facilities and consider actions, as appropriate, to avoid potential problems. However, suggestions contained in this IN are not NRC requirements; therefore, no specific action nor written response is required.
The Y2K problem pertains to the potential inability of computers to correctly recognize dates beyond December 31,1999. This problem results from computer hardware and/or software that uses two-digit fields to represent the year. These systems may misread the year 2000 and cause the systems to fail, generate faulty data, or act in an incorrect manner. The Y2K problem has the potential to interfere with the proper operation of any computer system, hardware that is microprocessor-based (embedded software), software, or database.
The Y2K problem is urgent because it has a fixed, non-negotiable deadline that is quickly approaching. This matter requires priority attention because of the limited time remaining to assess the magnitude of the problem, assess its associated risks, and implement programs that will achieve a satisfactory resolution of the Y2K problem.
Existing reporting requirements under 10 CFR Part 21 provide for notification to NRC of deficiencies, non-conformances, and failures, such as the Y2K problem, in safety-related systems.
As part of NRC's response to the Y2K problem, NRC assembled a Y2K team to gather more information on the Y2K programs of materials and fuel cycle licensees and certificate holders. During each interview, the licensee or facility representative indicated that they were aware of the Y2K issue and were in various stages of implementing their Year 2000 Readiness Program.
NRC learned that some early versions of treatment planning systems have Y2K problems, and upgrades for the systems were available. Treatment planning systems are regulated by the U.S. Department of Health and Human Services, Food and Drug Administration (FDA ), not NRC, although both agencies are sharing Y2K information. For materials licensees, no Y2K issues for NRC-regulated material were identified by the Y2K team. For fuel cycle facilities, a database was identified, by a facility, that had a Y2K problem. The facility indicated that they would convert to a Y2K-compliant database as part of their Y2K readiness program.
In addition, materials and fuel cycle inspectors have been instructed to confirm receipt of NRC's INs, by materials and fuel cycle licensees and certificate holders; determine whether the licensees and certificate holders have identified any potential problems associated with the Y2K issue; and note any corrective actions taken by the licensees and certificate holders.
NRC staff has several concerns associated with the potential impact of the Y2K problem on materials licensees, primarily because of the variety and types of computer systems and software in use. Licensees need to be aware of Y2K effects on health and safety, as well as regulatory requirements such as record-keeping.
The Y2K problem may affect hardware, software, embedded systems, and networks. Examples of systems that may be affected by the Y2K problem include:
- Treatment planning systems;
- Dose calibrators;
- Nuclear Medicine dose/operational management systems
- Programmable logic controllers;
- Commercial off-the-shelf software and hardware;
- Document control systems;
- Safeguards (Material Control and Accounting and Physical Protection) systems;
- Security computers and systems;
- Plant process (data scan, log, and alarm) display system computers;
- Safety parameter display system computers;
- Emergency response systems;
- Radiation monitoring systems;
- Dosimeters and readers;
- Engineering programs and systems;
- Communication systems;
- Inventory control systems;
- Surveillance and maintenance tracking systems; and
- Control systems.
Applications that have no apparent date manipulation algorithms may still be affected by a Y2K problem. For example, a subroutine that date-stamps the header information in archival tapes, regardless of the rest of the content of the tape, may be affected. In addition, individual systems may be "date-safe," but the integrated operations that the systems support may be vulnerable to the Y2K problem. Therefore, after testing a subsystem for Y2K compliance, a functional test of the entire system should be performed.
As part NRC's Y2K program, the Office of Nuclear Material Safety and Safeguards is monitoring several list servers, manufacturer websites, news articles, Congressional reports, and the President's Y2K Council reports for Y2K issues that may affect materials licensees. Materials inspectors are continuing to make Y2K inquiries during routine inspections. To date, only treatment planning systems, dose calibrators, and a tote position display for an irradiator have been identified through the inspection process as having Y2K problems. NRC has informed the FDA of all treatment planning systems and dose calibrators that have been linked to Y2K problems. Upgrades for these treatment planning systems and dose calibrators are available from manufacturers. Treatment planning systems are regulated by the FDA not the NRC. Materials inspectors have indicated that licensees are aware of the upgrades. The irradiator tote position display is not a safety system. Further, this system is a one-of-a-kind modification made by the licensee (the licensee was authorized by NRC to make the modifications). The licensee is updating the tote position display system to eliminate the Y2K problem. Although no generic Y2K issues for NRC-regulated material used by materials licensees have been identified, materials licensees need to continue implementation of their Y2K readiness programs.
Between September 1997 and October 1998, the major fuel cycle facilities were asked Y2K questions during other inspections. Based on these Y2K inspections, the facilities were aware of the Y2K problem and were adequately addressing Y2K issues.
In June 1998, NRC issued Generic Letter (GL) 98-03, "NMSS Licensees' and Certificate Holders' Year 2000 Readiness Programs," which requested written confirmation by December 31, 1998, from the major fuel cycle facilities that their computer systems were Y2K-ready and that they could operate safely before and after January 1, 2000. The GL also requested that if a facility was not Y2K-ready by December 31, 1998, a status report and schedule for remaining work would be sent to NRC by July 1, 1999.
Each major fuel cycle facility has responded to the GL and stated that they have implemented a Y2K readiness program. No facility stated that they were Y2K-ready by December 31, 1998; however, each facility has indicated that they will be Y2K-ready well before January 1, 2000. There have been no identified risk-significant Y2K concerns for fuel cycle facilities.
Finally, the International Atomic Energy Agency (IAEA) with the cooperation of the World Health Organization (WHO), is holding an International Workshop on "Safety Measures to Address the Year 2000 (Y2K) Issue at Medical Facilities which use Radiation Generators and Radioactive Materials", in Vienna, Austria, on June 28-30, 1999. The workshop will address the experiences of those who have already taken steps to assess and remediate the Y2K problem. The workshop program is largely based on a technical document (TECDOC-1074), published by the IAEA. Authorities in Member States of the IAEA and WHO and professional societies (radiotherapy, nuclear medicine, medical physics, radiation protection) will be invited by IAEA to participate.
Additional information, registration materials, and a downloadable version of TECDOC-1074 may be found at the IAEA website.
Attachment 1 contains brief descriptions and addresses of selected Y2K websites. Many manufacturers have websites that contain Y2K information regarding their products. Manufacturers' websites may include information on products that are not Y2K-compliant, and the availability of product updates. Government and professional organization websites that may be useful in addressing the Y2K problem are also included.
To alert licensees and certificate holders to the Y2K problem, NRC issued three Information Notices.
IN 96-70, "Year 2000 Effect on Computer System Software," on December 24, 1996 described the potential problems that computer systems and software may encounter as a result of the change from the year 1999 to the year 2000 and how the Y2K issue may affect NRC licensees and certificate holders. IN 96-70 encouraged licensees and certificate holders to examine their uses of computer systems and software well before the year 2000 and suggested that they consider appropriate actions to examine and evaluate their computer systems for Y2K vulnerabilities.
In IN 97-61, "U.S. Department of Health and Human Services Letter, to Medical Device Manufacturers, on the Year 2000 Problem," on August 6, 1997 the staff forwarded licensees an FDA letter sent to medical device manufacturers, regarding the Y2K problem. In the letter, dated June 25, 1997, FDA reminded medical device manufacturers that some computer systems and software applications currently used in medical devices, including embedded microprocessors, may experience problems as a result of the turn to the new century. In addition, the letter indicated that computer-controlled design, production, or quality control processes could be adversely affected.
IN 98-30, "Effect of the Year 2000 Computer Problem on NRC Licensees and Certificate Holders," on August 12, 1998 alerted licensees to systems that may be affected by Y2K and systems known to be affected by the Y2K problem. IN 98-30 encouraged licensees to contact vendors and test their systems for Y2K problems. Finally, IN 98-30 provided elements of a Y2K readiness program.
