DRAFT REQUEST FOR ADDITIONAL INFORMATION FIRSTENERGY NUCLEAR OPERATING COMPANY PERRY NUCLEAR POWER PLANT, UNIT 1 DOCKET NUMBER 50-440 CAC NUMBER MF9818; EPID L-2017-LLA-0241
By application dated June 8, 2017, FirstEnergy Nuclear Operating Company (FENOC), submitted a license amendment request (LAR) for Perry Nuclear Power Plant, Unit No. 1 (PNPP). The amendment would revise the technical specifications (TSs) to adopt TS changes provided by TSTF-522 and align with the licensing basis with changes provided by Amendment 166. Among the changes, the amendment would delete TS 3.7.8, "Fuel Handling Building," and TS 3.7.9, "Fuel Handling Building Ventilation Exhaust System."
Title 10 of the Code of Federal Regulations, Section 50.36, requires, in part, that a limiting condition for operation (LCO) be established for items that meet one or more of the criteria listed. In the LAR, you stated that the Bases for TS 3.7.8 and TS 3.7.9 currently cite criterion 3
and 4.
FENOC concluded that the deletion of TS 3.7.8 and TS 3.7.9 is acceptable for several reasons, including the fuel handling building (FHB) and fuel handling building ventilation exhaust system (FHBES) are not credited in mitigating the consequences of a fuel handling accident in the FHB, and FENOC does not intend to revise the existing accident analyses; therefore, the FHB and FHBES no longer meet the 10 CFR 50.36 criteria for establishing a TS LCO.
However, on page 7 of the Evaluation of Proposed License Amendment, FENOC stated that, "[t]he FHB will remain categorized as a safety-related, Seismic Category I structure and the FHBES will remain a safety-related, Seismic Category I system."
Because the FHB and FHBES will no longer be gover ned by TSs, please describe how they will be maintained as safety-related and seismic category I structure and system. Also describe the change control process that applies to any future changes to the FHB and FHBES.
