REQUEST FOR ADDITIONAL INFORMATION CONTAINMENT INTEGRITY ANALYSIS ENTERGY NUCLEAR OPERATIONS, INC, INDIAN POINT NUCLEAR GENERATING UNIT NO.3 DOCKET NO. 50-286 The Entergy request for technical specification changes states that a reanalysis of the containment analysis of the Indian Point Unit 3 large-break loss-of-coolant-accident was performed to address mass and energy release errors identified in Westinghouse Nuclear Safety Advisory Letter 11-5. Has the change in the calculated energy that is released to the containment been evaluated for effects on the emergency core cooling system sump net positive suction head margin that is credited in the Indian Point Unit 3 response to GL-2004-02?

If yes what is the effect?
