- The bundle Minimum Critical Heat Flux Ration (MCHFR), based on the Exxon Nuclear Corporation Synthesized Hench-Levy Correlation, must be above thir value.
"The actual dry out time for GE 9x9 fuel (based on the General 51ectric Dry Out Correlation for non-jet Pump Boiling Water Reactors, NEDE-20'J6) should be above the dry out time shown in Figure 1.
- To be determined by linear extrapolation from Table 2.
For operation with only one recirculating loop in service, these limits shall be reduced by 5 percent for Reloads F and Modified F and 10 percent for other fuel types.
