ME8409 and ME8410)
By letter dated March 16,2012 (Accession No. ML12079A111), FirstEnergy Nuclear Operating Company (FENOC) submitted a response to a Nuclear Regulatory Commission (NRC) information request made pursuant to 10 CFR 50.54(f) for Beaver Valley Power Station, Unit Nos. 1 and 2 (Accession No. ML120400672). The requested information was related to the estimated effect on peak cladding temperature resulting from thermal conductivity degradation in the Westinghouse Electric Company LLC (Westinghouse) furnished realistic emergency core cooling evaluation. In accordance with 10 CFR 50.46(a)(3), FENOC's response to the NRC request also served as a 30-day report of a significant emergency core cooling system evaluation model change or error. By letter dated May 4,2012 (Accession No. ML121150501), the NRC requested additional information to complete its review of FENOC's March 16, 2012 response. provides a proprietary version of the response to the NRC's May 4, 2012 request for additional information.
