Content:
BWRs based on acceptable coorelations (see SRP Section 4.4). c. An incident of moderate frequency should not generate a more serious plant condition without other faults occurring independently. d. An incident of moderate frequency in combination with any single active component failure, or single operator error, shall be considered and is an event for which an estimate of the number of potential fuel failures shall be provided for radiological dose calculations. For such accidents, the number of fuel failures must be assumed for all rods for which the DNBR or CPR falls below those values cited above for cladding integrity unless it can be shown, based on an acceptable fuel damage model (see SRP Section 4.2), that fewer failures occur. There shall be no loss of function of any fission product barrier other than the fuel cladding. The term "moderate frequency".is used in this SRP section in the same sense as in the descriptions of design and plant process conditions in References 10 and 11.
