NMP-2 AUDIT PLAN

Bhalchandra, Please send the following to the licensee as a supplement:

Review of TIP reports:

RAI-1 Since NMP2 power density is 51.86 MWt/Mlbm/hr (>50), provide a power distribution assessment to establish that neutronic methods axial and nodal power distribution uncertainties have not increased(Ref; letter NMP-2L2556)

We need discussion on the above response, Review of TIP Report is required to close this open issue:
