DBSIGN FEATURES

, 5.6 FUEL STORACE l: ' CRITICALITY

- 5.6.1.1 The new fuel storage racks are designed and shall'be maintained with sufficient center-to-center distance between' fuel assemblies placed in the.

storage racks.to ensure a k,gg equivalent to less than 0.90 when dry and less than 0.95 when flooded with unborated water. In order to meet these limits, j new fuel assemblies shall have an infinite core geometry lattice multiplication factor:less than nr. equal to 1.31 at'20*C.

5.6.1.2 .The spent fuel storage racks are designed and shall be maintained with sufficient center-to-center distance between fuel assemblies placed in the storage racks.te' ensure.a k,gg equivalent to less than 0.95 with the storage pool filled with unborated water with:

1

a. PWR fuel assemblies with a maximum infinite core geometry lattice multiplication factor less than'or equal to 1.41 at 20*C, b.- BWR fuel assemblies with a maximum infinite core geometry lattice '.

, multiplication' factor less than or equal to 1.33 at 20*C.

5.1.6.3 The k gg for the unpoisoned racks includes a conservative allowance of 0.5% ak/k f,r o uncertainties. The ketf calculated for the poisoned. racks

- includes the sum of all appropriate biases and the root-mean-square (RMS) of the uncertainties.

DRAINACE 5.6.2. The spent fuel storage pool is designed and shall be maintained to prevent inadvertent draining of the pool below elevation 116'4".

CAPACITY 5.6.3 The spent fuel storage pool is designed and shall be maintained with no more than 160 PWR fuel assemblies and 1803 BWR fuel assemblies.

5.7 COMPONENT CYCLIC OR TRANSIENT LIMIT

- 5. 7.1' The components identified in Table 5.7.1-1 are designed and.shall be maintained within the cycle or transient limits of Table 5.7.1-1.
