-Corrective Action status 3 P A L O V E R D E Purpose of CDBRVerify the Design Bases have been correctly implemented for high risk-

significant components and operator

actions.Verify the capability of these components

to perform their intended safety function.Verify interface requirements between

NSSS vendor and Architect-Engineer are

correct, complete and appropriately

incorporated into Design Bases.
