4 5.5-FUEL STORAGE i

A.

The new fuel storage facility shall be's'uch that the Kef t.ry -.is less than 0.90 and flooded is less than 0.95.

l B. -The K,,, of the spent fuel storage pool shall be less - than or equal to 0.95.

C.

Each fuel assembly in the spent fuel-pool shall have-a maximum K-infinity less than or equal to 1.32 and an enrichment of 4.6% U-235 or less averaged over the axial planar zone of. highest average enrichment.

D.

The number of spent' fuel assemblies stored in the. spent fuel pool shall not exceed 3859.

]

E.

Loads in excess of 2000 lbs. shall be prohibited from travel over [

fuel assemblies in the spent fuel storage pool.

F.

No fuel which has decayed for less than 200 days shall be stored in racks within an arc described by the height of theicask around the

. periphery of the energy absorbing pad.

5.6 SEISMIC DESIGN Tne station Class I structures and systems have been designed for ground ano 0.15 - (maximum - credible -

accelerations of 0.089 (design earthquake) 9 l

earthquake).

BASEh 5.5 FUEL STORAGE The fuel storage assembly K-infinity in Section 5.5.C refers to the maximum K-inf inity for the standard reactor core geometry.

Storage of fuel assemblies meeting specification 5.5.C will result in-K,ge less than 0.95 for both normal and abnormal storage conditions.
