hey will not cause an increase in K(eff) beyond the 48 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. 49 A statement in the SAR establishing the above condition as a design criterion is acceptable at the CP review stage. d. Design calculations should show that the storage racks and the anchorages can withstand the maximum uplift forces available from the lifting devices without an 9.1.1-7 DRAFT Rev. 3 - April 1996 increase in K(eff). A statement in the SAR that excessive forces cannot be applied due to the design of the lifting devices is acceptable if justification is presented. The evaluation procedures identified in SRP Section 9.1.4 are used to validate this statement. e. The vault and racks have been designed to preclude damage from dropped heavy objects. f. Sharing of a storage facility in multi-unit plants does not result in any added potential for increasing the K(eff) of the storage array. 3. The reviewer verifies that the safety function of the facility will be maintained, as required, if the facility is subjected to natural phenomena such as earthquakes, tornadoes, hurricanes, and floods. In making this determination, the reviewer considers the following points: a. The facility design basis and criteria, and the component classification tables presented in the SAR are reviewed to verify that the new fuel storage facility, including storage vault and racks, have been classified and will be designed to seismic Category I requirements. b. The essential portions of the new fuel racks and storage vault are reviewed to verify that protection from the effects of floods, hurricanes, tornadoes, and internally or externally generated missiles is provided. Flood protection and missile protection criteria are discussed in sections of the SRP contained in Chapter 3. The
