SUMMARY

OF TELEPHONE CONFERENCE CALL ON REQUEST FOR ADDITIONAL INFORMATION SEVERE ACCIDENT MITIGATION ALTERNATIVES PERTAINING TO THE SEABROOK STATION LICENSE RENEWAL APPLICATION December 18, 2013 The U.S. Nuclear Regulatory Commission (NRC) staff and representatives of NextEra Energy Seabrook, LLC (NextEra or the applicant) held a telephone conference call on December 18, 2013, to discuss the request for additional information (RAis) regarding the severe accident mitigation alternatives (SAMAs) for Seabrook Station license renewal application (LRA). The telephone conference call was useful in clarifying the RAis.

Discussion The staff and the applicant discussed the current draft RAis sent to the applicant on December 16, 2013 (Agency Document Access and Management System (ADAMS) Accession No ML13351A517) concerning the LRA and the SAMA review. The applicant requested clarification regarding the 2nd part of the RAI:

Dose Conversion Coefficient File: NextEra implemented what appears to be a custom dose conversion file in the SAMA analysis. The exact version of the dose conversion factor file used by NextEra in the SAMA analysis is needed to support our evaluation of conservatisms.

The discussion focused on what information was available in the dose conversion coefficient file and why the NRC thought the Seabrook file had been customized. After the discussion, the applicant said that it understood the staff's request for the dose conversion coefficient file in the RAI.
