... - DESIGN FEATURES DtSIGN PRESSURE AND TEMPERATURE (Continued)

b. For a pressure of:
1. 1250 psig on the suction side of the recirculation pump,
2. 1500 psig from the recirculation pump discharge to the outlet side of the discharge shutoff valve.
3. 1500 psig from the discharge shutoff valve to the jet pumps.
c. For a temperature of 575*F.

VOLUME 5.4.2 The total water and steam volume of the reactor vessel and recirculation system is approximately 22,400 cubic feet at a nominal steam dome saturation temperature of 547'F.

5.5 FUEL STORAGE CRITICALITY 5.5.1.1 The spent fuel storage racks are designed and shall be maintained with:

a. A k,y equivalent to less than or equal to 0.95 when flooded with unborated water, including all calculational uncertainties and biases as described in Section 9.1.2 of the FSAR.
b. A nominal 6.625 inch center-to-center distance between fuel assemblies placed in the storage racks.

5.5.1.2 The k,y for new fuel for the first core loading stored dry in the spent fuel storage racks shall not exceed 0.98 when aqueous foam moderation is assumed.

DRAINAGE 5.5.2 The spent fuel storage pool is designed and shall be maintained to prevent inadvertent draining of the pool below elevation 346'0".

CAPACITY <

5.5.3 The spent fuel storage pool is designed and shall be maintained with a storage capacity limited to no more than 2500 fuel assemblies. l 5.6 COMPONENT CYCLIC OR TRANSIENT LIMIT ,

5.6.1 The components identified in Table 5.6.1-1 are designed and shall be maintained within the cyclic or transient limits of Table 5.6.1-1.
