et forth in the final safety analysis report. The review procedures given are for a typical storage system. Any variance of the review, to adjust to a proposed unique design, is such as to assure that the facility design conforms to the criteria in subsection II of this SRP section. The reviewer selects and emphasizes mate- rial from this SRP section as may be appropriate for a particular case. On those occasions were the design deviates significantly from previously approved designs ASB will request the coordinating review branches to provide input for the areas of review stated in subsection I of this SRP section. The ASB will incorporate such input as required to assure that this review proce- dure is complete. 1. The quantity of new fuel to be stored onsite forms the basis for the design capacity of the vault and the number of storage racks provided. The SAR is reviewed to determine that the facility description includes the stor- age capacity provided by the design. The SARs for recent light-water reactor applications have stated that the storage space provided is con- sistent with the number of new fuel assemblies used during the refueling cycle. In general, storage capacity for approximately one-third of a core is usually provided for each unit of a plant (e.g., 1/3 core for single unit design and 2/3 core for a dual unit design). 2. The information provided in the SAR pertaining to criticality safety of the new fuel storage facility is evaluated by CPB upon request. The facil- ity design criteria, safety evaluation, system description, and the layout drawings for the storage vault and racks are reviewed to verify that: 9.1.1-3. Rev. 2 - July 1981 a. Criticality information (including the associated assumptions and input parameters) in the SAR must show that the spacing between fuel assemblies in the storage racks is sufficient to maintain the array, when fully loaded and flooded with potential moderators such as nonborated water fire extinguishant aerosols,
