Applies to storage facilities-for new and spent fuel assemblies. Objective To assure that both new and spent fuel assemblies will be stored in such a manner that an inadvertent criticality could not occur. Specification 5.4.1 NEW FUEL STORAGE

a. New fuel will normally be stored in the new fuel storage vault or spent fuel pools. The fuel assemblies are stored '

in racks in parallel rows, having a nominal center to i center distance of 21-1/8 inches in.both directions-for the new fuel storage vault. The fuel assemblies are  ; stored in racks in parallel rows, having a nominal center  : l to center distance of.11.1 inches in both directions for. p the Region I. racks and 9.20 inches in both directions for the Region -II racks for the Spent Fuel Pool "A"~ The fuel assemblies are stored in racks in parallel rows, having a

                              . sufficient to maintain a K effective of less than'.95-based on fuel assemblies with an enrichment of.4.3 weight                                                              :

When                                                                >

l k a e 5.4.2 SPENT. FUEL STORAGE

a. Irradiated fuel assemblies will be stored, prior to offsite shipment, in the stainless steel lined spent fuei pools, which are located in the fuel handling building,

b. Whenevea there is fuel in the pool except for initial fuel loading, the spent fuel pool is filled with water borated to the concentration used in the reactor cavity and fuel transfer canal,

c. Deleted.

d. The fuel assembly storage racks provided and the number of fuel elements each will store are listed by location below:

                                   ***~ Spent Fuel l Pool B contains spent fuel storage racks with a
                                         -center-to-center spacing of 13 5/8' inches to increase the-storage capacity of the pool.
