SUBJECT: NOTICE OF VIOLATION AND PROPOSED IMPOSITION OF CIVIL
PENALTY - $50,000 (NRC INTEGRATED INSPECTION REPORT NOS. 50-348 AND 50-364/96-09)
Dear Mr. Morey:
This refers to the inspection conducted during the period September 1 through October 12, 1996, at your Farley Nuclear Plant (FNP). The inspection included a review of the fire protection program associated with the installation and inspection of Kaowool fire barriers to meet the requirements of Appendix R to 10 CFR Part 50 and the FNP Fire Protection Plan. The results of this inspection were discussed with members of your staff on October 17, 1996, and were formally transmitted to you by letter dated November 8, 1996. In addition, on November 7, 1996, you submitted Licensee Event Report No. 96-006-00 which addressed Kaowool fire barrier installation deficiencies. A closed predecisional enforcement conference was conducted in the Region II office on November 18, 1996, with you and members of your staff to discuss the apparent violations, the root causes, and corrective actions to preclude recurrence. A list of conference attendees, NRC slides, and a copy of your presentation materials are enclosed. In addition, at the conference, you identified errors in and/or disagreement with certain statements expressed in the subject inspection report. The dispositon of your comments in this regard are also enclosed.
Based on the information developed during the inspection and the information that was provided during the conference, the NRC has determined that violations of NRC requirements occurred. The violations are cited in the enclosed Notice of Violation and Proposed Imposition of Civil Penalty (Notice), and the circumstances surrounding them are described in detail in the subject inspection report. The violation described in Part I of the Notice involved three examples of Southern Nuclear Operating Company Inc.'s (SNC) failure to assure that one-hour fire barriers, in this case Kaowool enclosures, were installed on Unit 1 electrical cables associated with systems required for safe shutdown. The components affected by the discrepant conditions were the dedicated B Train high head safety injection pump and its room cooler; the swing high head safety injection pump and its room cooler when aligned to the B Train; one B Train main steam line isolation valve; and the B Train motor driven auxiliary feedwater pump discharge flow control valves. The Kaowool in these areas was not installed as described in design drawings and your 10 CFR Part 50, Appendix R commitments.
At the conference, you admitted the violation and provided additional background information related to the circumstances surrounding the discrepancies and their identification. You described the root causes of the violation as personnel error and insufficient design guidance during initial installation, and stated that there was no reason to believe that a breakdown in your configuration management program occurred.
Although the failure to install Kaowool fire barriers adequately did not result in an actual safety consequence, under certain circumstances, a fire could have adversely impacted your ability to achieve and maintain safe plant shutdown conditions (e.g., loss of charging). Overall, the violation is of significant regulatory concern in that the degraded fire barriers increased the vulnerability of safety related equipment to potential fire hazard or damage and compromised the design objective of defense-in-depth. At the conference you stated that alternate methods were available to mitigate the consequences of a fire affecting these safety related components. Although NRC agrees that alternate methods were available to mitigate the consequences of a fire, several of these methods rely on operator recognition and intervention which are not proceduralized and cannot be assured for 10 CFR 50, Appendix R compliance; and, the fire suppression system relied upon to mitigate a fire involving both trains of high head safety injection experienced failures during April 1994 and 1995 surveillance testing. Furthermore, NRC is concerned that your independent verification program at the time of initial installation (implemented by your construction organization) failed to identify the non-conformances, as has your periodic inspection program since then. This resulted in unknown, degraded fire barriers for an extended period of time. Therefore, this violation is classified in accordance with the "General Statement of Policy and Procedures for NRC Enforcement Actions" (Enforcement Policy), NUREG-1600, as a Severity Level III violation.
In accordance with the Enforcement Policy, a base civil penalty in the amount of $50,000 is considered for a Severity Level III violation. Because your facility has not been the subject of escalated enforcement action within the last two years, the NRC considered whether credit was warranted for Corrective Action in accordance with the civil penalty assessment process described in Section VI.B.2 of the Enforcement Policy. At the conference, you stated that your corrective actions taken and/or planned include: (1) the prompt establishment of fire watches; (2) the conduct of a walk-down of motor-operated valve Kaowool installations following identification of deficiencies by the NRC; (3) conduct of a comprehensive inspection of all Kaowool installations in the plant utilizing newly trained, Level II inspectors; (4) correction of identified Kaowool installation discrepancies by January 31, 1997; (5) revision of Procedure FNP-0-FSP-43 to clearly identify the appropriate Kaowool periodic inspection criteria by January 31, 1997; and (6) conduct of additional training for the individuals who will implement the periodic inspection program. Although it appears that your corrective actions were ultimately comprehensive, the NRC determined that credit was not warranted for Corrective Action in that, collectively, your actions were not timely. Specifically, NRC identification of multiple examples of Kaowool and flammastic installation discrepancies over a several month period was required before you took comprehensive corrective actions. Although engineering reviews and evaluations were being performed as issues were identified, you did not institute the necessary positive actions to assess the extent of the condition and to characterize the Kaowool fire barrier discrepancies fully until NRC identified examples of missing Kaowool.
Therefore, to emphasize the importance of maintaining an adequate fire protection program for the protection of safety related equipment and the need for prompt and comprehensive corrective actions, I have been authorized, after consultation with the Director, Office of Enforcement, to issue the enclosed Notice in the base amount of $50,000 for the Severity Level III violation.
The violation described in Part II of the Notice has been categorized at Severity Level IV. It involved the failure to adequately implement a program for the periodic inspection of Kaowool installed fire barriers. These inadequate inspections, lack of qualified inspectors, and incomplete inspection criteria contributed to failure to identify the Kaowool installation and material condition discrepancies earlier.
You are required to respond to this letter and should follow the instructions specified in the enclosed Notice when preparing your response. The NRC will consider your response, in part, to determine whether further enforcement action is necessary to ensure compliance with regulatory requirements.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter, its enclosures, and your response will be placed in the NRC Public Document Room (PDR).

NOTICE OF VIOLATION AND PROPOSED IMPOSITION OF CIVIL PENALTY
Southern Nuclear Operating Company, Inc. Docket Nos. 50-348, 50-364
Farley Nuclear Plant License Nos. NPF-2, NPF-8
During an NRC inspection conducted during the period September 1 through October 12, 1996, violations of NRC requirements were identified. In accordance with the "General Statement of Policy and Procedures for NRC Enforcement Actions," NUREG-1600, the NRC proposes to impose a civil penalty pursuant to Section 234 of the Atomic Energy Act of 1954, as amended (Act), 42 U.S.C. 2282, and 10 CFR 2.205. The particular violations and associated civil penalty are set forth below:
I. Violation Assessed A Civil Penalty
10 CFR Part 50, Appendix R, Section III.G.2 requires, in part, where cables or equipment, including associated non-safety circuits that could prevent operation or cause maloperation of redundant trains of systems necessary to achieve and maintain hot shutdown conditions, are located within the same fire area outside of containment, the cables and equipment and associated non-safety circuits be separated by a fire barrier having a three-hour rating, or separated by a horizontal distance of more than 20 feet with no intervening combustibles or fire hazards, or one redundant train be enclosed in a fire barrier having a one-hour rating.
License No. NPF-2, Condition 2.C(4), for Farley Nuclear Plant (FNP), Unit 1, states, in part, that Southern Nuclear Operating Company, Inc. shall implement and maintain in effect all provisions of the approved fire protection program as described in the Final Safety Analysis Report (FSAR).
FSAR, Appendix 9B, Fire Protection Program, documents an evaluation of the FNP fire protection program as it complies with Appendix R to 10 CFR 50 and embodies the contents of the Fire Protection Program Reevaluation as approved by the NRC. Appendix 9B, Attachment B, 10 CFR 50 Appendix R Exemptions, provides the NRC's discussion and evaluation of the licensee's Appendix R exemption requests, and also identifies those systems and components that require one-hour Kaowool fire barriers to meet Appendix R.
Contrary to the above, the licensee failed to assure that electrical cables associated with systems necessary to achieve and maintain hot shutdown conditions were enclosed in an one-hour fire barrier as required by Appendix 9B of the FSAR as evidenced by the following examples:
1. On October 2, 1996, the NRC identified that the 1B and 1C Safety Injection Pump "B train" power cables in Room 160 of Fire Area 1-004 were not fully enclosed by a Kaowool fire barrier (approximately 18 feet of cable tray was unwrapped).
2. During the period of October 5-8, 1996, the licensee identified that the 1B and 1C Safety Injection Pump "B train" power cables and room cooler cables in Room 175 of Fire Area 1-004 were not fully enclosed by Kaowool fire barriers (approximately 24 inches of cable from four cable trays were unwrapped).
3. During the period of October 5-8, 1996, the licensee also identified that the cables for main steam isolation and auxiliary feedwater flow control in Room 319 of Fire Area 1-042 were not enclosed by an appropriate fire barrier, i.e., Kaowool, (the entire four foot span of cable tray was unwrapped). (01013)
This is a Severity Level III violation (Supplement I).
Civil Penalty - $50,000
II. Violation Not Assessed A Civil Penalty
License No. NPF-2, Condition 2.C(4), and License No. NPF-8, Condition 2.C(6), states, in part, that Southern Nuclear Operating Company, Inc. shall implement and maintain in effect all provisions of the approved fire protection program as described in the FSAR.
FSAR, Appendix 9B, Fire Protection Program, documents the evaluation of the FNP fire protection program against Appendix R to 10 CFR 50 and embodies the contents of the Fire Protection Program Reevaluation as approved by the NRC.
FSAR, Appendix 9B, Section 9B.6.1, requires periodic inspections of fire protection systems and equipment to assure acceptable condition of these items. Administrative Procedure, FNP-0-AP-36, Fire Surveillance Procedures and Inspections, Revision 12, required that fire surveillance procedures are performed as written, by qualified personnel, and that these procedures provide the necessary detailed requirements.
Fire Surveillance Procedure, FNP-0-FSP-43, Visual Inspection of Kaowool Wraps, Revision 5, provided the acceptance criteria, instructions, and references to installation details for conducting periodic inspections of Kaowool wraps used to provide the one-hour rated fire barriers prescribed by the Fire Protection Program of FSAR, Appendix 9B.
Contrary to the above, the licensee failed to implement an adequate periodic inspection program for Kaowool one-hour fire barriers in that:
1. The periodic inspections failed to verify that Kaowool fire barriers were being maintained in conformance with installation drawings and the acceptance criteria specified in Procedure FNP-0-FSP-43. During the period March 4-7, 1996, licensee personnel inspected Kaowool wraps in accordance with Procedure FNP-0-FSP-43 and did not identify any deficiencies. However, from July 24 - October 2, 1996, the NRC identified multiple examples of installation deficiencies and deteriorating conditions of Kaowool wraps. Subsequent inspections by the licensee conducted during the period October 5-8, 1996, identified over a hundred similar installation and degradation problems with existing Kaowool wraps around electrical raceways.
2. Personnel performing the periodic inspection required by Procedure FNP-0-FSP-43 during March 1996 were not qualified, in that they were not knowledgeable regarding the design, installation, or material condition requirements for Kaowool wraps. These individuals were not adequately trained on Kaowool requirements nor did they have adequate prior experience in installing or inspecting Kaowool.
3. As of October 12, 1996, Procedure FNP-0-FSP-43, Revision 5, did not clearly identify all the critical characteristics to be inspected to assure Kaowool fire barriers were maintained in conformance with installation drawings (e.g., flammastic fire seals and compression). (02014)
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, the Southern Nuclear Operating Company, Inc. (Licensee) is hereby required to submit a written statement or explanation to the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, within 30 days of the date of this Notice of Violation and Proposed Imposition of Civil Penalty (Notice).
