5.3 AUXILIARY.EOUIPMENT 5.3.1 Fuel Storage A.
Normal storage for unirradiated fuel assemblies is in j
critically safe new fuel storage racks in the reacser building i
storage vault; otherwise, fuel shall be stored in arrays which l*
have a K less than 0.95 under optimum conditions of moderati8bfor in NRC-approved shipping containers.
B.
The spent fuel shall be stored in the spent fuel storage facility which shall be designed to maintain fuel in a geometry providing a X,,less than or equal to 0.95.
C.
The fuel to be stored in spent fuel storage facility shall not exceed a maximum average planar enrichment of 3.01 w/o U-235.
D.
Coads greater than the weight of one fuel assembly shall not be moved over stored irradi.ated fuel in the spent fuel storage
- facility.
j E.
The spent fuel shipping caskishall n6t be 'lif ted more than six inches -
above the top plate of the cask drop protection system.
Yertical limit switches shall be operable to assure the six inch vertical limit is met whtn the cask.is above the top plate of the cask crop i
protection system.
\\
F.
The temperature of the water in the spent fuel stored cool, measured at or near the surface, shal.1 not exceed 125'F.',
G.
The maximum amount of spent fuel assemblies stored in the j
spent fuel storage pool shall be 2600.
BASIS ine specification of K less than or enual to 0.95 in the spent fuel storage f acility assures an am3?e margin from criticality.
Criticality analysis was perfermed on the poison racks to insure that a K of 0.95 would not be exceeded.
Thebasisforthisanalysisassumeda80 average planar lattice c riment of 3.01 w/o U-235 and includes nanufe.cturing tolerances.
Tre effects of a dropped fuel bundle onto stored fuel in the spent fuel storage ft:ility have been analyzed.
This analysis shows that the fuel bundle drco v.:d d not cause doses resulting fron ruptured fuel pins that exceed 10 CfR 100 linits (1,2,3) and that dropped waste cJns will not damage '.he pool liner, beacvt 'a. ;d.
