- Th3 bundle Minimus Critical Power Ratio (MCPR), based on the Exxon Nuclear C:rporation XN-2 Critical Power Correlation, must be above this value.
CiThe actual dry out time for GE 9x9 fuel (based on the General Electric Dryout C:rrelation for Nonjet Pump Boiling Water Reactors, NEDE-20566) should be above th3 dryout time shown in Figure 1.
CC0F r operation with only one recirculation loop in service these limits shall be r:duced by 5 percent for Reload F and Modified F and reduced by 20 percent for cther fuel types.
