Project Scope

- NSSS Design Input Core/NSSS power increasing from current 2775/2785 MWt by ~1.6-1.7%. Depends on calculated power uncertainty by Cameron with LEFM NSSS analyses will be performed at 2% increase (2831 core/2841 NSSS)

Bounds possible actual power levels Consistent with previous MUR programs Assessment of NSSS components, systems, and accident analyses will require a combination of evaluations and more detailed analyses depending on whether a 2% power uncertainty was part of the current analysis basis BOP assessments will consist mostly of evaluations

Special Considerations PAD5 will be included in effort Fuel rod temperatures/pressures generated with PAD5 Incorporated into affected "Not

-LOCA" analysis areas (Chapter 15 transients, containment, fuel rod design criteria, fuel nuclear design and thermal/hydraulic design)

Spent Fuel Pool Criticality As discussed, the SFP criticality analysis is to be updated The impact on the spent fuel for the MUR uprate will also be reflected in the analysis As this SFP criticality analysis LAR review will be performed in parallel with the MUR LAR review, SNC is requesting feedback regarding this logistic
