Title: ECCS Evaluations Models 
Abstract: The final rule amends the Commission's regulations that require safety analyses used for evaluation of emergency core cooling system (ECCS) under loss-of-coolant-accident (LOCA) conditions be conducted at 1.02 times the licensed power for the plant. The final rule allows licensees to propose increases in licensed power levels for plants using Appendix K evaluation models, but the ECCS safety analyses could assume power levels less than the current requirement. Licensees will need to demonstrate that the reduced margin for assumed power level in the analyses for their facility is justified.
