Ocean Drive, Jensen Beach, FL 34957 L-2017-056 Attachment  Page 1 of 3 St. Lucie Units 1 and 2 10 CFR 50.46 Annual Report  Emergency core cooling system (ECCS) analyses for St. Lucie Unit 1 and St. Lucie Unit 2 are performed by AREVA and Westinghouse Electric Company (W), respectively. The following information pertaining to the evaluation models for small break loss of coolant accidents (SBLOCA) and large break loss of coolant accidents (LBLOCA), and the application of such models to each St. Lucie Unit, is provided pursuant to 10 CFR 50.46(a)(3)(ii). A summary of calculated peak cladding temperature (PCT) changes is provided in Tables 1 and 2 (for St. Lucie Units 1 and 2, respectively). The data interval for this report is from January 1, 2016 through December 31, 2016. A discussion of the changes follows. 1.0  ST LUCIE UNIT 1  1.1 Changes to SBLOCA  No errors were found in the SBLOCA ECCS performance analysis since the previous annual report of Reference 3.1. Table 1 provides a summary of PCT changes for St. Lucie Unit 1. 1.2 Changes to LBLOCA  No errors were found in the LBLOCA ECCS performance analysis since the previous annual report of Reference 3.1. Table 1 provides a summary of PCT changes for St. Lucie Unit 1. 2.0 ST. LUCIE UNIT 2  2.1 Changes to SBLOCA  No errors were found in the SBLOCA ECCS performance analysis since the previous annual report of Reference 3.1. Table 2 provides a summary of PCT changes for St. Lucie Unit 2. 2.2 Changes to LBLOCA  No errors were found in the LBLOCA ECCS performance analysis since the previous annual report of Reference 3.1. Table 2 provides a summary of PCT changes for St. Lucie Unit 2.
