JAFP-16-0121 0 CFR 50.46(a)(3)(ii) Annual Report on Changes and Errors in Emergency Core Cooling System (ECCS) Evaluation Models for the period from August 1, 2015 to July 31, 2016 Page 1 of 3 INTRODUCTION This report summarizes changes and errors in emergency core cooling system (ECCS) evaluation models in accordance with 10 CFR 50.46(a)(3)(ii) for the period August 1, 2015 to July 31, 2016 for Entergy's James A. FitzPatrick Nuclear Power Plant. There are no new changes or errors reported during this period. FitzPatrick has been operating with the same models and analysis as reported in the last update, see Reference 7. The JAF core is comprised of GNF2 fuel. The base licensing basis Peak Cladding Temperature (PCT) is 1800°F as reported in Reference 2. The PCT adjusted for changes and errors is 1900°F as shown in Table 1, which remains below the 2200°F acceptance criterion of 10 CFR 50.46.
