SUMMARY

OF THE AUDIT TO SUPPORT THE REVIEW OF THE TECHNICAL SPECIFICATION TASK FORCE-425 LICENSE AMENDMENT REQUEST (TAC NO. ME9733)

Dear Mr. Heacock:

The Millstone Power Station Unit 3 (MPS3) submitted a license amendment request (LAR),

dated October 4, 2012 (Agencywide Documents Access and Management Systems Accession Number ML12284A213), to relocate technical specification surveillance frequencies to a licensee controlled program with the adoption of Technical Specification Task Force (TSTF) 425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control - Risk-Informed Technical Specification Task Force (RITSTF) Initiative 5b." The Office of Nuclear Reactor Regulation, Division of Risk Analysis, Probabilistic Risk Assessment Licensing Branch (APLA) performed a regulatory audit for its review of the LAR.

The audit was performed at the request of the licensee, and was conducted at the Dominion Federal Affairs office in Washington, D.C. on January 29 and 30, 2013. Specifically, the scope of the audit was to review closed findings and observations (F&Os) for the internal events probabilistic risk assessment model used in support of the application. The list of participants is provided in Enclosure 1.

The audit was conducted by APLA staff. An entrance meeting was held on January 29,2013, and during the audit period, documents were reviewed. The list of documents reviewed is provided in Enclosure 2. The audit reviewed the closed F&Os, and concluded that there was no need for any follow-on request for additional information on them since they had been appropriately addressed. However, some potential follow-on questions on open F&Os (related to gap numbers 3 and 9 of the LAR) were discussed. Any additional information needed to support the LAR review will be formally requested by the staff utilizing the request for additional information process in accordance with Office of Nuclear Reactor Regulation Office Instruction L1C-101, "License Amendment Review Procedures." APLA staff re-capped its review of the closed F&Os, and noted the two potential questions noted above on open F&Os, at the exit meeting held on January 29, 2013 with MPS3 staff.
