5.5 Fuel Storage 4 A. The new fuel' storage facility shall be such that the K,ff dry is less than ) -

0.90 and flooded in less than 0.95.

3. The spent fuel storage racks are designed and shall be maintained with a ,

nominal 6 9/16 inch center-to-center distance between fuel assemblies placed in the storage racks to ensure a Kegg equivalent to < 0.95 with l the storage pool filled with unborated water. The K f, has been con-servativelycalculatedtobe0.9271whichiswellbu$oOthe=aximum allowable K of. 0.95 as described in Section X-3.5 of Volume IV of the

'SAR. In ad$kfion, fuel'in the storage pool shall have a U-235 loading of 3

< 14.5 grams of U-235 per axial centimeter of fuel assembly.  !

C. The spent fuel storage pool is designed and shall be maintained with a f Storage Capacity limited to no more than 2366 fuel assemblies, D. The fuel handling bridge fuel hoist has a load-limit cell set at no more than 1230 pounds. .f 5.6 Seismic Design

[

The seismic design for-Class I structures and equipment is based on dynamic analyses using acceleration response spectrum curves which are based on a ground motion of 0.1.g. The vertical ground acceleration assumed is equal to of the horizontal ground acceleration. For'the design of Class I structures and equipment, the maximum horizontal and vertical accelerations were con- ,

sidered to occur simultaneously. Where' applicable, stresses were added r

directly.  !-

The combined stresses resulting from dead, live, pressure, thermal and earthquake having a ground acceleration of 0.2g are such that a safe shut-  ;

down can be achieved. [

5.7 Barge Traffie r

Barge traf fic on the Missourt River past the site has been analyzed to i determine that the present size and cargo materials do not create a hazard -

to the safe operation of the plant. Contact will be maintained with the i Corps of Engineers to determine if and when additienal analyses are required due' to changes in barge size or cargo. ,
