SUMMARY
OF DECEMBER 3, 2012, PRE-LICENSING PUBLIC MEETING WITH STP NUCLEAR OPERATING COMPANY HELD VIA CONFERENCE CALL TO DISCUSS THE PROPOSED RISK-INFORMED APPROACH TO THE RESOLUTION OF GSI-191, "ASSESSMENT OF DEBRIS ACCUMULATION ON PWR SUMP PERFORMANCE" (TAC NOS. ME7735 AND ME7736)
On December 3,2012, a public meeting was held via conference call between the U.S. Nuclear Regulatory Commission (NRC) and representatives of STP Nuclear Operating Company (STPNOC, the licensee), at NRC Headquarters, Rockville, Maryland. The purpose of the meeting was to discuss the licensee's proposed licensing approach to the resolution of Generic Safety Issue (GSI)-191, "Assessment of Debris Accumulation on PWR [Pressurized-Water Reactor] Sump Performance," for South Texas Project (STP), Units 1 and 2. The meeting notice and agenda are located in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML12321A122. The licensee previously provided an overview of its proposed approach during the public meetings held on June 2, July 7, July 26, August 22, October 3, November 1, November 2, and December 1, 2011, and February 9, March 1, March 8, March 29, June 11, September 6, 2012, and October 10, 20121.
The licensee discussed the following licensing strategy that it intends to pursue for a risk informed approach to resolving GSI-191.
- STPNOC would initially submit an exemption request only.
- STPNOC would evaluate the effects of debris accumulation and in-vessel effects based on the performance of the sump during long-term cooling for those breaks associated with events that cumulatively fall within Region III of NRC Regulatory Guide (RG) 1.174, "An Approach for Using Probabilistic Risk Assessment in Risk~lnformed Decisions on Plant-Specific Changes to the licensing Basis." .
- STPNOC would request a partial exemption from the provisions of paragraph 50.46(b)(5), "Long-term cooling," of Title 10 of the Code of Federal Regulations Summaries of the meetings held on June 2, July 7, July 26, August 22, October 3, November 1, November 2, and December 1, 2011, and February 9, March 1, March 8, March 29, June 11, September 6, and October 10, 2012, are available in ADAMS at Accession Nos. ML111640160, ML111950094, ML112130165, ML112411419, ML112840114, ML113120129, Ml113180196, ML113430087, ML120620541, ML120830103, ML120830086, ML121380522, ML12187A081, ML12270A055, and ML12300A297, respectively.
-2 (10 CFR), for loss-of-coolant accident (LOCA) events that cumulatively fall within Region III of RG 1.174. Specifically, 10 CFR 50.46(a)(1)(i) requires that:
ECCS cooling performance must be calculated in accordance with an acceptable evaluation model and must be calculated for a number of postulated loss-of-coolant accidents of different sizes, locations, and other properties sufficient to provide assurance that the most severe postulated loss-of-coolant accidents are calculated.
STPNOC would seek an exemption from demonstrating that long-term cooling performance acceptance criteria are met with an acceptable evaluation model for LOCA events that cumulatively fall within Region'" of RG 1.174. Based on meeting the criteria of RG 1.174, the licensee would not perform sump strainer tests or any other calculations that demonstrate adequate pump net positive suction head and that in-vessel effects limits are maintained under the most severe postulated LOCAs.
- The exemption would support closing NRC Generic Letter 2004-02, "Potential Impact of Debris Blockage on Emergency Recirculation during Design Basis Accidents At Pressurized-Water Reactors," for STP for compliance with 10 CFR 50.46, based on NRC approval of the exemption request.
- The licensee's exemption request would reference the supporting analysis. This analysis will be maintained in the licensee's Records Management System (RMS) and would be part of the exemption request.
- This analysis would be maintained and controlled under the licensee's PRA program.
- The licensee would change the STP updated final safety analysis report (UFSAR) based on the NRC staff's safety evaluation for the exemption.
The NRC staff queried the licensee about several aspects of the proposed approach and discussed potential problems to be considered before going forward. These include, in part,

- The NRC staff would expect the licensee to submit for approval the model/methodology/test results used in any of the licensee's evaluations of piping breaks, in addition to the evaluations.
- 3 No regulatory decisions were made at the meeting. A list of meeting attendees is enclosed. No Public Meeting Feedback forms were received.
