SUBJECT:
Beaver Valley Power Station, Units No. 1 and 2 BVPS-1 Docket No. 50-334, License No. DPR-66 BVPS-2 Docket No. 50-412, License No. NPF-73 Beaver Valley Power Station P.O. Box 4 Shippingport, PA 15077 724-682-5234 Fax: 724-643-8069 Notification of Schedule Change and Revision of Regulatory Commitment Regarding Submittal of 10 CFR 50.48(c) License Amendment Request (TAC Nos. ME0058, ME0059) By memorandum dated June 10, 2011, "Staff Requirements-SECY 11-0061 -A Request to Revise the Interim Enforcement Policy for Fire Protection Issues on 10 CFR 50.48(c) to Allow Licensees to Submit License Amendment Requests in a Staggered Approach" (RIN 3150-AG48) (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 11161 0616), the Nuclear Regulatory Commission approved a staff recommendation to revise the existing enforcement policy regarding the extension of enforcement discretion for certain noncompliances related to fire protection programs. To obtain the extension, licensees were required to submit a letter by June 29, 2011, acknowledging a new commitment date for submittal of their license amendment application to adopt National Fire Protection Association Standard NFPA 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants, 2001 Edition, in accordance with Section 50.48(c) of Part 50 of Title 10 of the Code of Federal Regulations (10 CFR 50.48(c)). By letter dated June 29, 2011 (ADAMS Accession No. ML 111800765), FirstEnergy Nuclear Operating Company (FENOC) established a formal regulatory commitment to submit an application for license amendment to implement 10 CFR 50.48(c) at Beaver Valley Power Station, Units No. 1 and 2 (BVPS) on or before September 30, 2012, and requested extension of the enforcement discretion period for BVPS under the terms and conditions provided in SECY 11-0061, as approved by the Commission.
Beaver Valley Power Station, Units No. 1 and 2 L-12-313 Page 2 On July 12, 2011, the Nuclear Regulatory Commission (NRC) published in the Federal Register (76 FR 40777) the Interim Enforcement Policy for Certain Fire Protection Issues, formally establishing terms and conditions consistent with those provided in SECY 11-0061, as approved. By letter dated August 1, 2011 (ADAMS Accession No. ML 112010151), the NRC concluded that FENOC's letter of June 29, 2011 was consistent with Commission direction established in SRM SECY-11-0061, and granted the request for the extension of enforcement discretion. The term of enforcement discretion was extended to correspond with the License Amendment Request (LAR) submittal date. Upon submittal of an acceptable application for license amendment, enforcement discretion for previously identified noncompliances and any newly identified noncompliances could remain in effect until the NRC dispositions the license amendment request. The NRC project manager for BVPS was notified on July 2, 2012, of the potential for a NFPA 805 LAR schedule extension. On August 1, 2012, a Category 1 public meeting was held between the NRC and representatives of FENOC to discuss the status of the proposed LAR. Specifically, FENOC provided notification to the NRC staff that the committed due date for the subject NFPA 805 LARwill not be met. Additional information to support that conclusion is provided herein. During the transition to NFPA 805, FENOC has continued to maintain fire safety at BVPS Units No. 1 and 2 in accordance with the Facility Operating Licenses. Violations identified through NRC inspection activities have been limited to issues of very low safety significance, and have been determined to satisfy the criteria specified for the exercise of enforcement discretion. Noncompliances are addressed through the FENOC corrective action program, and where necessary, appropriate compensatory measures are in place. FENOC remains fully committed to the improvement of fire protection programs through voluntary implementation of 10 CFR 50.48(c) at Beaver Valley, and has made significant progress in several key areas of the NFPA 805 transition project. Notwithstanding the above, the effort required to complete transition efforts and develop a high-quality license amendment application for BVPS has been more substantial than originally anticipated, and the benefit from the synergy of a dual-unit application has been less than expected. Additionally, several unforeseen developments have affected the project completion schedule; some of the more significant developments are as follows:
- To incorporate lessons learned during the development of the BVPS Unit No.2 Fire Probabilistic Risk Analysis (FPRA) model, the Solid State Protection and Instrumentation portions of the BVPS Unit No.1 FPRA model were updated. The resultant impact on the previous schedule was an approximate three month delay.
Beaver Valley Power Station, Units No. 1 and 2 L-12-313 Page 3
- During the Fire Risk Evaluation process it was discovered that the BVPS Unit No. 1 control room abandonment portion of the FPRA model requires additional risk reductions to meet the core damage frequency (CDF) criteria established in Regulatory Guide 1.17 4, An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis. To develop a strategy to reduce risk, FENOC is currently performing engineering feasibility studies on potential design modifications for those fire ignition sources in the BVPS Unit No. 1 Process Rack Area that are impacting risks. The resulting effect on the transition schedule is currently under evaluation.
- The discovery of and risk effect determination for BVPS Unit No. 1 Licensee Event Report 2011-001-00, "Use of Liquid Tight Conduits Installed in Fire Barrier Penetrations Results in Unanalyzed Configurations," resulted in the diversion of project resources, and a resultant impact of approximately two months on the previous schedule. The effects of the issue resolution on the project schedule (potential analysis changes and design modification) are still being evaluated.
- Although the BVPS Unit No. 2 Human Reliability Analysis Dependency Analysis was very similar to the BVPS Unit No. 1 analysis already determined to be acceptable, a BVPS Unit No. 2 FPRA peer review finding required a significant effort to revise the analysis. The resultant impact on the previous schedule was an approximate four month delay. Consistent with Section 9.1 of the Interim Enforcement Policy, FENOC is providing the following information to justify a revised submittal schedule. Evaluations to date have resulted in some completed modifications in BVPS Unit No. 1, and additional ongoing and conceptual future modifications have been identified for both units. Appropriate modifications will be completed in a timely manner and will result in improved fire safety at BVPS, as envisioned when the NFPA 805 transition process was undertaken. Completed design modifications, the purposes they are intended to achieve, and the current status of each, are provided in Attachment 1. Similar information for ongoing and conceptual design modifications is provided in Attachment 2. The modifications listed in Attachment 2 are subject to change as Fire Risk Evaluations and further design review activities are completed. The plant modification work already identified, the additional analytical work required as a result of lessons learned during the NFPA evaluation process, and the evaluation of issues identified through NRC review of applications submitted by other licensees all make it clear that additional effort is required, particularly in the areas of Fire Risk Evaluation and PRA model development, in order for FENOC to develop an Beaver Valley Power Station, Units No. 1 and 2 L-12-313 Page4 amendment application of sufficient quality and completeness for BVPS. As a result of FENOC's assessment of the BVPS NFPA 805 project progress to date, FENOC has revised the forecast for submittal of the LAR for NFPA 805 transition at BVPS. Major project activities and milestones for the BVPS transition to a fire protection program based on NFPA 805 are reflected in Attachment 3. Consistent with the revised forecast for LAR submittal, the regulatory commitment established in the FENOC correspondence dated June 29, 2011 is hereby revised. FENOC will submit the application for license amendment to implement 1 0 CFR 50.48(c) at BVPS Units No. 1 and 2 on or before December 31, 2013. While the forecast date for submittal of an acceptable license amendment application is firm, intermediate milestones identified in Attachment 3 are subject to change as project development progresses. To support any NRC staff reviews of NFPA 805 transition progress at BVPS, the following transition related information will be made available for NRC staff review:
- A listing of all fire protection-related noncompliances and the related compensatory measures for those noncompliances;
- Documentation ensuring each Operator Manual Action put in place as a compensatory measure is feasible and reliable, in accordance with the guidance in Regulatory Issue Summary 2005-07, "Compensatory Measures to Satisfy the Fire Protection Program Requirements"; and,
- A description of the physical modifications performed, to address existing fire protection issues and noncompliances. The Interim Enforcement Policy for Certain Fire Protection Issues published on July 12, 2011 states, in part: If the licensee is unable to submit its license amendment request (LAR) within the timeframe stated above, it will lose its enforcement discretion. However, licensees with appropriate justification and staff approval may regain enforcement discretion once an acceptable LAR is submitted. On February24, 2012, the NRC staff issued SECY-12-0031, Enforcement Alternatives for Sites that Indicate Additional Time Required to Submit Their License Amendment Requests to Transition to 10 CFR 50.48(c) National Fire Protection Association Standard 805, which presented the staff's available alternatives regarding enforcement issues in such cases. To determine how to best support the general objectives of the staff as established in SECY -12-0031, FENOC has evaluated the scenarios and potential alternative NRC responses outlined by the staff.
Beaver Valley Power Station, Units No. 1 and 2 L-12-313 Page 5 The preferred alternative would have a licensee preserve its enforcement discretion by arranging for the substitution of the LAR submittal from another site by the committed date. Such an arrangement would result in little or no impact on the staff or the resources budgeted for the LAR review schedule, but would be subject to staff acceptance based on the comparative safety benefits of the sites involved. Use of this alternative is not feasible for the BVPS situation, because current industry commitments have no plants scheduled to submit in a time frame necessary to support FENOC's needs. Additionally, discussions at a recent industry meeting identified no plants that would be willing to accept FENOC's current commitment for submittal by September 30, 2012. Another alternative addressed in SECY-12-0031 would apply if a licensee does not submit an acceptable LAR by its commitment date, and the extension of enforcement discretion has not otherwise been arranged. In such cases, the staff would shift to annual performance of fire protection inspections, and take appropriate enforcement actions for identified noncompliances. Based on the timing and results of recently performed triennial fire protection inspections, the limited extent of identified noncompliance issues to which enforcement discretion is currently applied, and the projected schedule for completion of the NFPA 805 transition efforts, FENOC perceives minimal safety or regulatory benefit achieved by this approach. The remaining alternative involves NRC issuance of a confirmatory order (CO) to extend enforcement discretion thereby establishing an enforceable date for the submittal of an acceptable LAR. To support this approach, a licensee is required to provide adequate justification including the consideration of the status of the industry peer review, plant modifications, the licensee's compliance reviews, and the resolution of methodology issues. Given these considerations as well as others previously addressed, FENOC believes the justification provided in this letter to be adequate for the extension of enforcement discretion by way of a CO. FENOC also understands that the issuance of a CO would involve the agreement to comply with the terms and conditions arising out of the regulatory commitments established herein, consent to the issuance of the confirmatory order, and the waiver of hearing rights. Based on the above considerations, FENOC hereby requests the continuation of the current enforcement discretion for certain fire protection issues for BVPS Units No. 1 and 2 until an acceptable application for license amendment is submitted, consistent with the regulatory commitment established in this letter. FENOC also requests that, consistent with the current Interim Enforcement Policy for Certain Fire Protection Issues, such enforcement discretion be further extended through the period of NRC review of the application.
