- The required Shutdown Margin capability of 1 %Alr/k in MODE 1 and MODE 2 is preserued by the Regulating Rod lnsertion Limits specified in Figures 2a through 2d as required by Technical Specilication 3.2.1.
- " Entry into Mode 1 Physics Tests Exceptions is not supported by existing analyses. For example, Regulating Rod Shutdown Margin lnsertion Limits assumptions may not be met and as such requires actual shutdown margin to be > 1 %Aldk via alternate verification or calculation,
- For the period from 0 to 300 EFPD and for power levels 60 %FP and above, rod insertion limits are established that re$erve an additional 0.5 %Aldk required rod worth to accommodate the future implementation of an update to the SBLOCA model.
