September 2, 2014 MEMORANDUM TO: Sheena A. Whaley, Chief Hazards Management Branch Japan Lessons-Learned Division Office of Nuclear Reactor Regulation FROM: Juan F. Uribe, Project Manager /RA by Nicholas DiFrancesco for/

SUMMARY

OF THE JUNE 12, 2014, CATEGORY 1 PUBLIC MEETING WITH SALEM NUCLEAR GENERATING STATION, UNITS 1 AND 2 TO DISCUSS SEISMIC HAZARD REEVALUATIONS ASSOCIATED WITH IMPLEMENTATION OF JAPAN LESSONS-LEARNED NEAR-TERM TASK FORCE RECOMMENDATION 2.1.

On June 12, 2014, the U.S. Nuclear Regulatory Commission (NRC or the staff) held a Category 1 public meeting1 with PSEG Nuclear, LLC (PSEG, the licensee) for Salem Nuclear Generating Station, Units 1 and 2 (Salem). The purpose of this meeting was to discuss issues resulting from the staffs screening and prioritization of Salem relating to Enclosure 1, Recommendation 2.1: Seismic, issued on March 12, 2012, Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f) Regarding Recommendations 2.1, 2.3, and 9.3, of the Near-Term Task Force Review of Insights From the Fukushima Dai-Ichi Accident.2 By letter dated May 9, 2014,3 the NRC staff categorized Salem, as a conditional screen in, prioritization group 3 plant with a risk evaluation due by December 31, 2020, based on the staffs screening review. By memo dated May 21, 2014, the NRC staff documented their preliminary Ground Motion Response Spectra (GMRS) curve in comparison to all licensee GMRS curves along with the plants Safe Shutdown Earthquake (SSE) and Individual Plant Examination of External Events (IPEEE) High Confidence Low Probability of Failure (HCLPF)

Spectra, also known as the IHS (IPEEE HCLPF Spectra). The public meeting supported an information exchange and understanding of engineering differences to achieve subsequent technical resolution.

To facilitate the discussion, the NRC staff and PSEG representatives presented4 the engineering details on the modeling inputs used to develop GMRS curves. The meeting highlights included:

1 The original meeting notice is available via the Agencywide Documents Access and Management System (ADAMS) under Accession No. ML14163A126.

2 The 50.54(f) letter and Enclosure 1 are available under ADAMS Accession Nos. ML12053A340 and ML12056A047.

3 The May 9, 2014 letter is available in ADAMS under Accession No. ML14111A147.

4 The NRC and PSEG slides can be found in ADAMS under Accession Nos. ML14162A440 and ML14162A432.

S. Whaley

• NRC and licensee discussed differences in methods used to calculate kappa (i.e. soil seismic energy damping)

• NRC and licensee discussed differences in velocity profiles, available onsite data, and modeling epistemic uncertainties represented in the profiles

• Based on interactions the NRC staff would consider licensee information and develop a request for additional information (RAI) to resolve differences In summary, the NRC staff stated that the primary differences between the NRC staff and licensee GMRS curves appear to result from:

• The different treatment of damping from the Potomac Group soil formation

• Total kappa value used

• Total amount of base cases used in the analysis (the licensee used 3 and the NRC used 1)

Finally, the NRC staff stated that a follow up RAI may be issued to document the licensees technical basis and background information, as well as any other clarifications associated with the information presented at the meeting.

No regulatory decisions or commitments were made during the meeting. The public was invited to observe the meeting and was given several opportunities to communicate with the NRC during the public meeting and before adjourning. The NRC staff received no public comments and no meeting feedback forms.
