SWR PG&E stated that the annual environmental reports submitted to the California Energy Commission are transmitted electronically; therefore, the correspondence requested in draft RAI SWR-1 is not available. The NRC staff agreed to delete Include associated transmittal correspondence with the CEC from the request.

SWR PG&E stated that the portion of the RAI requesting an evaluation of trends in the frequency of operating with two auxiliary saltwater pump trains is incorrect in that the plant does not operate with two auxiliary saltwater pumps. Rather, in accordance with Technical Specification Limiting Conditions for Operation 3.7.9, a second heat exchanger is placed in service when inlet temperature exceeds 64 degrees Fahrenheit. As such, the NRC staff modified the statement to read, As part of the response address whether there is any apparent trend in the frequency or annual hours of operation in accordance with Technical Specifications Limiting Conditions for Operation 3.7.9, Condition A.
