REVIEW RESPONSIBILITIES Primary - Accident Evaluation Branch (AEB) Secondary - Effluent Treatment Systems Branch (ETSB) I. AREAS OF REVIEW This SRP section covers the review of the radiological consequences of a postulated fuel handling accident. The purpose of the review is to evaluate the adequacy of system design features and plant.procedures provided for the mitiga- tion of the radiological consequences of accidents that involve damage to spent fuel. Such accidents include the dropping of a single fuel assembly and handling tool or of a heavy object onto other spent fuel assemblies. Such accidents may occur inside the containment, along the fuel transfer canal, and in the fuel building. The review includes the following: 1. The review is concerned with the selection of values of plant parameters for use in calculating the radiological consequences of a fuel handling accident, and the selection of the dose computation model, including assumptions of transport mechanisms and rates from the fuel handling area to the atmos- phere, breathing rates, dose conversion factors, and other data that may affect the calculated dose. 2. The calculated doses are compared with the appropriate exposure guidelines to determine the acceptability of the exclusion area boundary and low popu- lation zone (LPZ) boundary and to confirm the adequacy of the engineered safety features (ESF) provided for the purpose of mitigating potential accident doses. 3. The containment ventilation system is reviewed with respect to its function as a dose mitigating engineered safety feature (ESF) system for a fuel handling accident inside the containment, including the radiation detection system on the containment purge/vent lines for those plants that will vent or purge the containment during fuel handling operations..
