RE: Attendees - DCPP/NRC telecon on proposed LTSP Seismic Methodology License Amendment Signed By:
james.polickoski@nrc.gov
- Tom, As discussed, we appreciate the opportunity to further the process discussions between PG&E and the NRC staff regarding your anticipated license amendment request submittal.
After reviewing your overview of the Friday, May 27, 2011 teleconference between the NRC staff and members of the PG&E staff, email clarification is necessary on a couple of key points:
- 1. Upon review of meeting notes and meeting summaries from the previous three pre-application public meetings between the NRC staff and PG&E dated December 9, 2010, January 26, 2011, and March 31, 2011 (ML103610074, ML110420183, and ML111320637 respectively) and the official meeting transcript from the March 31, 2011 public meeting webcast (ML111020379), the NRC staff does not find evidence that PG&E had proposed the Hosgri Spectra and analysis methodology as the Safe Shutdown Earthquake. We look forward to discussing this proposal at future meetings, but the NRC does not support the PG&E assertion that this aspect of the PG&E proposal was discussed at the aforementioned meetings.
- 2. Regarding the plant design and licensing basis, the NRC understanding is that the OBE (DE), SSE (DDE), and the Hosgri (HE) are explicit, different, and mutually exclusive equipment performance criteria with respect to each other (as defined in the FSAR) and with respect to SSC equipment qualification.
We understand PG&E will request a meeting to discuss the proposal to elevate the Hosgri spectra as the SSE in the near future and are awaiting the next steps to discuss and review your submittals within the license amendment pre-application and regulatory review process.

Attendees - DCPP/NRC telecon on proposed LTSP Seismic Methodology License Amendment
Alan & Jim Per today's telecon.
Attendees:
PG&E Ken Peters Engineering Vice President Loren Sharp Engineering Director Norm Abrahamson Geosciences Steve David Director, Site Services Tom Baldwin Manager, Regulatory Services Philippe Soenen Supervisor, Licensing NRC Alan Howe Deputy Director - NRR/DORL Mike Markley Chief, Branch IV Plant Licensing - NRR/DORL Jim Polickoski Project Manager - DCPP - NRR/DORL Kamal Manoly NRR/DE Yong Li NRR/DE/EMCB Michael Peck Region IV, DCPP SRI Geoff Miller Region IV, DCPP Branch Chief Bob Latta Region IV, acting for Tom Farnholtz
Purpose:
- 1) Clarify PG&E's scope of a proposed LAR that had been discussed at three previous public meetings.
- 2) Establish whether there is a need for another prelicensing meeting PG&E stated that the proposed LAR had 3 purposes:
- 1. Establish the HOSGRI spectra and analysis methodology as the Safe Shutdown Earthquake
- 2. Specify the details of the Long Term Seismic Plan (LTSP) methodology for approval as the method of assessing new seismic information with respect to existing design and licensing basis information.
- 3. Clarify the LTSP commitments.
There was initially some misunderstanding that the DCPP HOSGRI evaluation was limited to a single train. PG&E clarified that all Reg Guide 1.29 SSCs were qualified to meet the HOSGRI analysis. PG&E further clarified that the qualification of all the SSCs was done prior to obtaining the operating license and that the qualification was reviewed and accepted by the NRC.
The NRC stated that they had been ready to receive the LAR with items 2 and 3, but that their learning of item 1 posed additional scope that would be a challenge for their planned review. The NRC encouraged PG&E to hold another public meeting to discuss this additional scope and the specifics of the request prior to submittal. The
NRC also stated that if PG&E submitted without another public meeting they would follow their process with the LAR.
The NRC stated that the had been working with the NEI LATF to establish a pre-application process to reduce the need for RAIs and were very encouraged about the possible improvements in the overall licensing process. They encouraged PG&E to use the process.
PG&E thanked the NRC for the telecon and stated they would discuss whether PG&E would request another public meeting prior to submittal. PG&E stated they would contact the DCPP project manager Jim Polickoski next week regarding how they would proceed.
