C:ntrol rod withdrawal during power operation shall be such that the average rate of ch:nge of reactor power is less than 50 MW per minute when power is less than 120 MWg ,

loca chan 20 MW per minute when power is between 120 MWg and 200 MWg , and 10 MW per cinute when power is between 200 MWgand 240 MWe

• CThe bundle Minimum Critical Power Ratio (MCPR), based on the Exxon Nuclear Corporation XN-2 Critical Power Correlation, must be above this value, ccThe actual dry out time for GE 9x9 fuel (based on the General Electric Dryout Correlation for Nonjet Pump Boiling Water Reactors, NEDE-20566) should be above the dryout time shown in Figure 1.

CCCF r operation with only one recirculation loop in service these limits shall be reduced by 5 percent for Reload F and Modified F and reduced by 20 percent for other fuel types.
