DESIGN FEATURES 5.3 REACTOR CORE FUEL ASSEMBLIES 5.3.

1 The r'eac&r core shall contain 217 fuel assemblies with each fuel assembly containing 236 fuel rods clad with Zircaloy-4.

Each fuel rod shall have a nominal active fuel length of 136.7 inches and contain a maximum total weight of 1698.5 grams uranium.

The initial core loading shall have a maximum enrichment of 2.73 weight percent U-235.

Reload fuel shall be similar in physical design to the initial core loading and shall have a maximum enrichment of 3.70 weight percent U-235.

CONTROL ELEMENT ASSEMBLIES 5.3.2 The reactor core shall contain 83 full-length control element assemblies and no part-length control element assemblies.

5.4 REACTOR COOLANT SYSTEM I

DESIGN PRESSURE AND TEMPERATURE 5.4.

1 The Reactor Coolant System is designed and shall be maintained:

a.

In accordance with the code requirements specified in Section 5.2 of the FSAR Qith allowance for normal degradation pursuant of the applicable Surveillance Requirements, b.

For a pressure of 2485 psig, and c.

For a temperature of 650 F, except for the pressurizer which is 700 F.

LUCIE - UNIT 2

. DESIGN FEATURES VOLUME 5,4.2 The total water and steam volume of the reactor coolant system is 10,931

+ 275 cubic feet at a nominal T

of 572'F.

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 CRITICALITY 5.6.T a.

The spent fuel storage racks are designed and shall be maintained with:

DRAINAGE ff equi val ent to 1 ess than or equal to 0. 95 when flooded wit3 unborated water, which includes a conservative allowance of 0.024 dk ff for Total Uncertainty.

eff A nominal 8.96 inch center-to-center distance between fuel assemblies placed in the storage racks.

3.

A boron concentration greater than or equal to 1720 ppm.

Region I can be used to store fuel which has a U-235 enrichment less than or equal to 4.5 weight percent.

Region II can be used to store fuel which has achieved sufficient burnup such that storage in Region I is not required.

The initial enrichment vs.

burnup requirements of Figure 5.6-1 shall be met prior to storage of fuel assemblies in Region II.

The new fuel storage racks are designed for dry storage of unirradiated fuel assemblies having a U-235 enrichment less than or equal to 4.5 weight percent, while maintaining a

k f of less than or equal to 0.98 under the most reactive conditi5(.

5.6.2 The spent fuel storage pool is designed and shall be maintained to prevent inadvertent draining of the pool below elevation 56 feet.

CAPACITY 5.6.3 The spent fuel storage pool is designed and shall be maintained with a storage capacity limited to no more than 1076 fuel assemblies.

5.7 COMPONENT CYCLIC OR TRANSIENT LIMITS 5.7.1 The components identified in Table 5.7-1 are designed and shall be maintained within the cyclic or transient limits of Table 5.7-1.
