e , 's ENCLOSURE

. JAN 04 ma AUXILIARY SYSTEMS BRANCH

, REQUEST FOR ADDITIONAL INFORitATION MCGUIRE NUCLEAR STATION, UNITS l&2 DOCKET NOS. 50-369/370 10.24 a. Demonstrate that the insertion of the proposed spacer (9.1.4) in the storage rack will not block or restrict the fluid flow necessary for spent fuel decay heat removal.

b. Demonstrate that the location and method of attaching the 5-1/2" spacers in the McGuire fuel racks do not

}

nullify the McGuire fuel rack seismic Category I design.

The effect of gaps, sloshing water, and increase of effective mass and damping due to submergence in water should be considered. Provide drawings to show the location and means of attaching the spacer in the storage rack.

c. Describe the measures that will be taken to assure that only Oconee fuel assemblies can be stored in the storage rack locations where the 5-1/2" spacers are inserted, and how to prevent McCuire fuel being stored in such loca-tions inadvertently.

l

d. Discuss the adverse consaquences of storing the McGuire fuel assemblies in location which are allocated for Oconee fuels, i .e. , locatiens where 5-l/2" spaters are at'. ached.

.. J. .

1. N04 M8 10.24 Discuss the consequences if one or more of the 5-1/2" spacers were not in place when the Oconee fuel bundle is inserted _into a spent fuel rack.

e. Indicate the maximum quantity of Oconee spent fuel (RSP) assemblies that will be stored in the McGuire facility.

Will there be sufficient storage space for emergency unloading of an entire McGuire cone following i ts startup?

f. Demonstrate that the special fuel handling tool for Oconee fuel will have the same seismic and quality group classification as McGuire fuel handling equipment. In addition, demonstrate that the special handling tool is capable of holding its load during a seismic event.

g. Describe the hoist which will be used to handle Oconee spent fuel assemblies. Demonstrate that the maximum uplift force of the hoist will not exceed the design limit of the McGuire spent fuel storage rack or the Oconee spent fuel essembly,

h. You indicate that a portion of the Oconee fuel assembly would extend above the fuel rack when stored in the l

l McGuire facility) Provide the results of an analysis
