DRAFT DRAFT REQUEST FOR ADDITIONAL INFORMATION OFFICE OF NUCLEAR REACTOR REGULATION REQUEST FOR ADDITIONAL INFORMATION RELATED TO AN AMENDMENT TO ADOPT TECHNICAL SPECIFICATIONS TASK FORCE TRAVELER TSTF

-425 TO RELOCATE SPECIFIC SURVEILLANCE FREQUENCIES TO A LICENSEE CONTROLLED PROGRAM BEAVER VALLEY POWER STATION

- UNITS 1 AND 2 DOCKET NO. 50

-344 AND 50

-412 By letter dated October 18, 2013

, 1 as supplemented by letter dated June 26, 2014, 2 FirstEnergy Nuclear Operating Company (the licensee) submitted a license amendment request for Beaver Valley Power Station (BVPS) Units 1 and 2.

The proposed amendment would modify the BVPS Technical Specifications by relocating specific surveillance frequencies to a licensee controlled program with the implementation of Nuclear Energy Institute (NEI) 04

-10, "Risk-Informed Technical Specifications Initiative 5b, Risk

-Informed Method for Control of Surveillance Frequencies

," (TSTF-425). To complete its review, the Nuclear Regulatory Commission staff requests a response to the questions below.

In response to RAI 6, submitted by letter dated June 26, 2014, the licensee directed the staff to a Facts and Observations (F&O) table in their National Fire Protection Administration 805 Supplement dated on February 14, 2014.

3 The tables in the supplement included all F&Os from previous peer reviews, consistent with the information in the submittal, and some focused scope peer review F&Os for Human Reliability Analysis (HRA) and Internal Flooding (IF). During the review of the IF F&Os in Table 1

-4, some F&Os appear to be resolved for the Internal Events PRA (in the column BVP S-1 Final Resolution), yet kept as open for the Fire PRA model.

RAI 7: Clarify if the BVPS Unit s 1 and 2 F&Os from the IF focused scope peer review are considered resolved for the TSTF

-425 application.

RAI 8: In addition, indicate which IF F&Os from the focused scope peer review, if any, were considered to be at Capability Category I

. 2 ADAMS Accession No. ML14177A514.

3 ADAMS Accession Number ML14051A499.

F&O HR-PR-007 states, in part, that; Post-maintenance misalignments were excluded for normally operating system[s] based on the assumption that misalignments on normally operating systems would be quickly detected and corrected.

RAI 9: Since the standby components are important for the TSTF

-425 application, please explain how the likelihood of post

-maintenance misalignment for the standby components are modeled in the internal events PRA.
