Acceptance of Diablo Canyon Power Plant (DCPP) License Amendment Reqest Regarding Auxiliary Feedwater System (TAC Nos ME6360 and ME6361)

Tom and Philippe, By letter dated June 1, 2011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML111530114), Pacific Gas and Electric Company. (PG&E, the licensee) requested an amendment to the Facility Operating License for the DCPP. The license amendment request (LAR) proposes to revise Technical Specification (TS) 3.7.5, "Auxiliary Feedwater (AFW) System," to incorporate changes consistent with the following NRC-approved Technical Specification Task Force (TSTF) Travelers:

• TSTF-245, Revision 1, "AFW Train Operable when in Service,"

• TSTF-340, Revision 3, "Allow 7 Day Completion Time for a Turbine-driven AFW Pump Inoperable,"

• TSTF-412, Revision 3, "Provide Actions for One Steam Supply to Turbine Driven AFW/EFW Pump Inoperable," and

• TSTF-439, Revision 2, "Eliminate Second. Completion Times Limiting Time From Discovery of Failure To Meet an LCO." The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff's acceptance review of this amendment request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

Consistent with Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), an amendment to the license (including the technical specifications) must fully describe the changes requested, and following as far as applicable, the form prescribed for original applications. Section 50.34 of 10 CFR addresses the content of technical information required. This section stipulates that the submittal address the design and operating characteristics, unusual or novel design features, and principal safety considerations.

The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the staff to complete its technical review, you will be advised by separate correspondence.
