a DESIGN FEATURES 5.5 METEOROLOGICAL TOWER LOCATION
~
5.5.1 The meteorological tower shall be located as shown on Figure 5.1-1.
5.6 FUEL STORAGE i
CRITICALITY - SPENT FUEL 5.6.1.1 The spent fuel racks are designed and shall be maintained so that the calculated effective multiplication factor is no greater than 0.95 (including all known uncertainties) when the pool is flooded with unborated water.
CRITICALITY - NEW FUEL 5.6.1.2 The new fuel storage racks are designed and shall be maintained with a nominal 26.0 inch center-to-center distance between new fuel assemblies such that K gg will not exceed 0.98 when fuel having a maximum e
enrichment of 5.0 weight percent U-235 is in place and aqueous foam moderation is assumed and K,gg will not exceed 0.95 (including a conservative allowance for uncertainties) when the storage area is flooded with unborated water.
i DRAINAGE 5.6.2 The spent fuel storage pool is designed and shall be maintained to prevent inadvertent draining of the pool below elevation 399' 10%".
CAPACITY 5.6.3 The spent fuel storage pool is designed and shall be maintained with 4
a storage capacity limited to no more than 988 fuel assemblies.
