REQUEST FOR ADDITIONAL INFORMATION LICENSE AMENDMENT REQUEST TO TRANSITION FIRE PROTECTION PROGRAM TO NATIONAL FIRE PROTECTION ASSOCIATION STANDARD 805 (NFPA 805)

RENEWED FACILITY OPERATING LICENSE NO. DPR-51 ENTERGY OPERATIONS, INC.

ARKANSAS NUCLEAR ONE, UNIT NO. 1 DOCKET NO. 50-313

PRA RAI 19 In Section 4.5.1.1 of the license amendment request (LAR) dated January 29, 2014 (ADAMS Accession No. ML14029A438), the licensee states that the "ANO-1 base internal events PRA (ANO-1 PSA Model 4p00) was the starting point for the Fire PRA." It is unclear to the U.S.

Nuclear Regulatory Commission (NRC) staff when this internal events PRA model was last updated to incorporate changes to the plant and procedures unrelated to NFPA-805. In Section 4.8.2 of the LAR dated January 29, 2014, the licensee also states that following installation of the modifications in Table S-1 of Attachment S to the LAR, additional updates to the Fire PRA model may be necessary. In Table S-2 of Attachment S to the LAR, Implementation Item S2-9, the licensee states that the PRA model update "will be performed in accordance with Entergy fleet PSA Maintenance procedure EN-DC-151, Section 5.2."

Please describe how the procedures in Entergy fleet PSA procedure EN-DC-151 will ensure that the risk contribution from plant modifications and changes unrelated to NFPA-805, included together with the modifications and changes listed in Attachment S to the LAR, will "ensure the as-built change-in-risk" will not "exceed the PRA model change-in-risk estimates reported in the LAR," as stated in Implementation Item S2-9.
