| الوصف: | Pursuant to 10 CFR 50.46, "Acceptance criteria for emergency core cooling systems for light-water reactors, " Westinghouse Electric Company is submitting this report to document any emergency core cooling system (ECCS) evaluation model changes or errors that affect the temperature calculation for the AP1000 Standard Plant Design. There are no additional Best Estimate LOCA (BELOCA) model changes that affect the temperature calculation to the items reported in the last 10 CFR 50.46 report documented in letter DCPNRC_002824, dated March 18, 2010. Westinghouse reported an error that affected the Small Break LOCA (SBLOCA) where use of incorrect inputs were found to have been utilized in the calculation as the adiabatic rod heat-up during the 10-inch break analysis of the AP 1000. The first error was related to inconsistent units being utilized in the equation for the rod average power. The second error was the use of an incorrect cross-sectional area term to represent the cladding in the adiabatic heat-up calculation. These changes represent Non-Discretionary changes in accordance with Section 4.1.2 of WCAP-13451. This information was reported in a 30 day reporting letter June, 2010 to the NRC (DCPNRC_002943). The limiting Transient for the AP1000 Certified Design as documented in the AP1000 DCD (Revision 15, dated December 8, 2005) is the Best Estimate Large Break Loss-of-Coolant Accident (BELOCA). The peak cladding temperature (PCT) is 2158°F for the BELOCA and does not exceed the 10 CFR 50.46 (b)(l) acceptance criterion of 2200'F. The summary of the updated PCT margin allocations and their bases |
