Report Summary:

A review was conducted of correspondence and required notifications from General Electric Hitachi and Global Nuclear Fuel - Americas, LLC (GNF); the GNF Supplemental Reload Licensing Report for Perry 1 Reload 15 I Cycle 16; and the FENOC corrective action program database. For 2014, the review identified one methodology change and three errors.

By correspondence dated June 18, 2014 (Accession No. ML14170A178), FENOC notified the NRC of the one methodology change and three errors, as required by 10 CFR 50.46(a)(3)(ii). In its correspondence, FENOC provided a summary assessment of the methodology change and errors. FE NOC also stated the peak cladding temperature (PCT) is 1555 degrees Fahrenheit (°F), and that it continues to satisfy the 10 CFR 50.46(b)(1) criteria of PCT not to exceed 2200°F. For 2014, no other methodology changes or errors were identified.
