SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 350 TO RENEWED FACILITY OPERATING LICENSE DPR-55 DUKE POWER COMPANY LLC OCONEE NUCLEAR STATION, UNIT 3 DOCKET NO. 50-287
1.0 INTRODUCTION
By letter dated August 18, 2005, as supplemented September 15, 2005, and January 5 and April 6, 2006, Duke Power Company LLC (the licensee), submitted a request for changes to the Oconee Nuclear Station, Unit 3, Technical Specifications (TSs). The requested changes would revise TSs 3.5.2.6 and 3.5.3.6 to accommodate the replacement of the reactor building emergency sump (RBES) suction inlet trash racks and screens with strainers. Similar amendments were issued for Units 1 and 2 on November 1, 2005; however, the amendment for Unit 3 was not issued at that time since the licensee had not completed its evaluation of the impact of pipe whip, jet impingement and internally generated missiles for Unit 3.
The supplements dated September 15, 2005, and January 5 and April 6, 2006, provided clarifying information that did not change the scope of the original application and the initial proposed no significant hazards consideration determination.
2.0 REGULATORY EVALUATION
Nuclear Regulatory Commission (NRC) Generic Letter (GL) 2004-02, Potential Impact of Debris Blockage on Emergency Recirculation During Design Basis Accidents and Pressurized Water Reactors, is part of the regulatory framework the NRC staff is using to address issues associated with Generic Safety Issue (GSI)-191, Assessment of Debris Accumulation on PWR Sump Performance, for requirements to improve evaluation of plant capability to meet Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Section 50.46(b)(5).
The new strainers are functionally equivalent to the existing trash racks and screens for meeting requirements of 10 CFR 50.46(b)(5) for long-term cooling and 10 CFR Part 50, Appendix A, Criterion 35 for emergency core cooling.
3.0 TECHNICAL EVALUATION
The proposed change involves revising TS Surveillance Requirements 3.5.2.6 and 3.5.3.6 to use the term "strainers" to replace the terms "trash racks and screens. This change is needed to reflect the replacement of RBES suction inlet trash racks and screens with strainer
assemblies in response to NRC Generic Letter 2004-02. The new strainers are functionally equivalent to the existing trash racks and screens for meeting the requirements of 10 CFR 50.46(b)(5) for long-term cooling and 10 CFR Part 50, Appendix A, Criterion 35 for emergency core cooling. The use of the generic term "strainers" can be used for both the existing and new designs, will not affect implementation of Surveillance Requirements 3.5.2.6 and 3.5.3.6, and can be used for implementation of corrective actions to address GSI-191.
GSI-191 was established by the NRC to determine whether transport and accumulation of debris in pressurized-water reactor (PWR) containments following a loss-of-coolant accident (LOCA) would impede the long-term operation of the emergency core cooling system or containment spray system. The NRC is currently implementing its plan to have all PWR licensees evaluate the potential for excessive head loss across the containment sump screen and implement necessary actions to resolve concerns associated with GSI-191. This action plan includes review of all licensee responses to GL 2004-02 and plant audits as needed to confirm proper evaluation and corrective actions to address all technical issues associated with proper sump performance. The information that was provided by the licensee regarding jet impingement and pipe whip effects, and missile protection, will be reviewed as part of this action plan.
The NRC staff has reviewed the licensees regulatory and technical analyses in support of its proposed license amendment, which are described in Attachments 3, 4, and 5 of the licensees August 18, 2005, submittal and finds these justifications acceptable.
On November 1, 2005, similar amendments were issued for Units 1 and 2; however, the amendment for Unit 3 was not issued at that time since the licensee had not completed its evaluation of the impact of pipe whip, jet impingement, and internally-generated missiles for Unit 3. By letter dated April 6, 2006, the licensee provided the results of these evaluations.
The NRC staff has reviewed Dukes evaluation of pipe whip, jet impingement and internally generated missile impact on the emergency sump strainer. The sources and targets were identified by a walkdown of Unit 1 and applied to Unit 3 on the basis of similarity. Duke Calculations S-005 "Missile Evaluation for the Emergency Sump Strainer," and S-006, "Jet Impingement and Pipe Whip Evaluation for the Emergency Sump Strainer," document the walkdown results and perform the analysis of the findings. The calculations document that Unit 3 piping arrangement in the area of the RBES is similar to that of Unit 1 & Unit 2. The NRC staff concurs with the conclusions of these calculations. Based on this evaluation, the licensee concludes that the emergency strainer operability will not be compromised during a LOCA by missiles, jet impingement or pipe whip. The NRC staff concludes that there are no credible missiles nor credible high-energy line break jets or pipe whips that could damage the strainer when needed during a LOCA.
Based on the review of the calculations provided by the licensee, the NRC staff grants approval of the proposed TS changes with regard to the evaluation for jet impingement, pipe whip and internally-generated missile impact of the RBES for Unit 3.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the South Carolina State official was notified of the proposed issuance of the amendments. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment changes requirements with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes surveillance requirements. The NRC staff has determined that the amendment involves no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (70 FR 51852). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
6.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
