REQUEST FOR ADDITIONAL INFORMATION LICENSE AMENDMENT REQUEST TO UPDATE PRESSURE-TEMPERATURE LIMIT CURVES DUKE ENERGY CAROLINAS, LLC OCONEE NUCLEAR STATION UNITS 1, 2, AND 3 DOCKET NOS. 50-269, 50-270, 50-287 (TAC NOS. ME0763, ME0764, AND ME0765)
Section 2.1.2.1.4 of the RAI response dated September 10, 2013, states, the predicted 54 EFPY fluences at the lower shell forging to Dutchman forging welds are greater than 1017 n/cm2 (E>1 MeV) for all three Oconee RPVs. Therefore, adjusted reference temperature values for the lower head components (transition ring forging, lower head, and their associated welds) were calculated in accordance with Regulatory Guide 1.99, Revision 2 using the lower shell forging to Dutchman forging weld fluences. Please address the upper-shelf energy requirement for the lower head components.
