yout drawings for the spent fuel pool and storage racks is reviewed to verify that: a. Criticality information (including the associated assumptions and input parameters) in the SAR must show that the center-to-center spacing between fuel assemblies and any strong fixed neutron absorbers in the storage racks is sufficient to maintain the array, when fully loaded and flooded with nonborated water, in a subcritical condition. A K not greater than 0.95 for this condition is acceptable. eff b. The design of the storage racks is such that a fuel assembly cannot be inserted anywhere other than in a design location. c. Failures of nonsafety-related systems or structures not designed to seismic Category I that are located in the vicinity of the spent fuel storage facility are reviewed to assureensure that their failure will not cause an increase in K to 61 eff exceed the maximum allowable. The SAR description section, the general arrangement and layout drawings, and the tabulation of seismic design classifications for structures and systems are reviewed and evaluated to assureensure that this condition is met. A statement in the SAR establishing the 62 above condition as a design criterion is acceptable at the CP review stage. d. Design calculations should show that the storage racks and any anchorages can withstand the maximum fuel handling equipment uplift forces without an increase in K or a decrease in pool water inventory. A statement in the SAR that excessive eff forces cannot be applied due to the design of the fuel handling equipment is 9.1.2-9 DRAFT Rev. 4 - April 1996 acceptable if justification is presented. The evaluation procedures identified in SRP Sections 9.1.4 and 9.1.5 are used to validate this statement. e. Conventionally the plant's Technical Specification states that the weight of all loads being handled above stored spent fuel shall not exceed that of one fuel assembly and its associated handling tool. This weight and its normal carrying height above
