REVIEW RESPONSIBILITIES Primary - Auxiliary Systems Branch (ASB) Secondary - Chemical Engineering Branch (CMEB) I. AREAS OF REVIEW All nuclear reactor plants include a spent fuel pool for the wet storage of spent fuel assemblies. The methods used to provide cooling for the removal of decay heat from the stored assemblies vary from plant to plant depending upon the individual design. The safety function to be performed by the system in all cases remains the same; that is, the spent fuel assemblies must be cooled and must remain covered with water during all storage conditions. Other functions performed by the system, not related to safety, include water cleanup for the spent fuel pool, refueling canal, refueling water storage tank and other equipment storage pools; means for filling and draining the refueling canal and other storage pools; and surface skim- ming to provide clear water in the storage pool. The ASB review of the spent fuel pool cooling and cleanup system covers the system from inlet to and exit from the storage pool and pits, the seismic Category I water source and piping used for fuel pool makeup, the cleanup system filter-demineralizers and the regenerative process to the point of discharge to the radwaste system. 1. The capability of the spent fuel pool cooling and cleanup system to provide adequate cooling to the spent fuel during all operating conditions is reviewed on one of two bases. The first basis requires the cooling portion of the sys- tem to be designed to seismic Category I, Quality Group C requirements. The second basis allows a non-seismic Category I, Quality Group C, spent fuel pool cooling system provided that the following systems are designed to seismic Category I requirements and are protected against tornadoes: the fuel pool make-up water system and its source; and, the fuel pool building and its ven- tilation and filtration system. The makeup, ventilation and filtration sys- tems must also withstand a single active failure. In
