APS/Westinghouse Meeting with NRC June 26 2003
- Background The S2M EM Generic Topical Report was approved by the NRC in December of 1997 for all CE PWR's without any Conditions or Limitations related to Core Power The NRC SER for the S2M EM concluded the model provided "improved realism" while retaining "significant conservatism" The S2M EM is currently the licensing basis for all 3 PV units at 3876 MWt In fact, S2M is required to be used by the approved and implemented: Zirlo topical
- Background The Unit 2 power uprate draft SER proposes a License Condition that would impose the S1 M EM at PVNGS on the basis that S2M has not been approved for power levels above 3400 MWt This proposal is contrary to NRC's approval of the S2M EM The NRC is using the PV docket and this licensing action to reopen the evaluation of an approved EM The proposed License Condition (workaround) in the Unit 2 power uprate draft SER creates a licensing basis problem for all 3 PV units not just PV Unit 2
- Background We do not see a clear success path through this problem if we are required to revert to S1 M due to the complexities it introduces into our current licensing basis The power uprate SER would have to supersede previous License Amendment SERs as well as approved topical report SERs
- GOALS for this meeting Gain acceptance that the S2M Evaluation Model, as originally approved by the NRC in the existing SER, is not power level dependent and, as such, is applicable at 3990 MWt Obtain a mutually agreed upon schedule for a revision to the applicable section of the Power Uprate draft SER for PVNGS-2

pat frahevin state goal The requested sensitivity calculations have been completed These demonstrate that the S2M hot rod heatup calculation is not uniquely impacted by variations in core power The NRC accepts the applicability of the S1 M to PVNGS-2 at 3990 MWt, and The blowdown hydraulics calculation for the S2M is essentially identical to that of the S1 M, therefore It is appropriately concluded that the S2M EM is applicable to a core power level of 3990 MWt
