5.6 FUEL STORAGE CRITICALITY 5.6.1.1 The spent fuel storage racks are designed and shall be maintained with: .

a. Ak ~

df equivalent to 1ess than or equal to 0.95 when flooded with

,. unborated water, which includes a conservative allowance of 2.6*.

ok/k for uncertainties as described in Section 4.~3 of the FSAR.

Th.is is based on new fuel with an enrichment of Sc5Fweight percent -

U-235 in Region 1 and on spent fuel with combination of initial enrichment and discharge exposures, shown in Figure 5.6-1, in Region 2; and

b. A nominal inch center-to-center distance between fuel assemolles placed in the storage racks.
5. 6.1. 2 The k for new fuel for the first core loading stored dry in the
  • spent fuel stoke racks shall not exceed 0.98 when aqueous foam moderation is assumed.

ORAINAGE 5.6.2 The spent fuel storage pool is designed and shall be maintained to prevent inadvertent draining of the pool below elevation 2040 feet.

CAPACITY 5.6.3 The spent fuel storage pool is designed and shall be maintained with a storage capacity limited to no more than 1344 fuel assemblies.

5. 7 COMPONENT CYCLIC OR TRANSIENT LIMIT
5. 7.1 The components identified in Table 5.7-1 are designed and shall be maintained within the cyclic or transient limits of Table 5.7-1.
