o DESIGN FEATURES 5.5 METEOROLOGICAL TOWER LOCATI0li 5.5.1 The meteorological tower shall be located as shown on Figure 5.1.2-1.
5.6 FUEL STORAGE CRITICALITY 5.6.1 The spent fuel storage racks are designed and shall be maintained with:
a.
A k,,, equivalent to less than or equal to 0.95 whan flooded with unborated water, including all calculational uncertainties and biases as described in Section 9.1 of the FSAR.
b.
A nominal 6.26-inch center-to-center distance between fuel assemblies 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 storage racks shall not exceed 0.98 when aqueous foam moderation is assumed.
DRAINAGE 5.6.2 The spent fuel storage pool is designed and shall be maintained to prevent inadvertent draining of the pool below elevation 202'5.1/4".
CAPACITY 5.6.3 The spent fuel storage capacity is designed and shall be maintained with a storage capacity limited to:
)
a.
No more than 4348 spent fuel assemblies in the spent fuel pool, and b.
No more than 800 spent fuel assemblies in the upper containment pool.
Placement of fuel in the upper containment pool is limited to temporary storage of fuel during refueling operations.
Prior to return to reactor criticality, all spent fuel shall be removed from the upper containment pool.
5.7 COMPONENT CYCLIC OR TRANSIENT LIMIT 5.7.1 The components. identified in Table 5.7.1-1 are designed and shall be i
maintained within the cyclic or transient limits of Table 5.7.1-1.
