DESIGN FEATURES 5.3 REACTOR CORE FUEL ASSEMBLIES 5.3.1 The core shall contain 193 fuel assemblies with each fuel assembly normally containing 264 fuel rods clad with Zircaloy-4, except that limited substitution of fuel rods by filler rods consisting _ of Zircaloy-4 or stainless -

steel. or by vacancies may be made if justified by a cycle-specific reload analysis.

Each fuel rod shall have a nominal active fuel length of 144 inches.

and contain a maximum total weight of 1766 grams uranium.

Reload fuel shall be similar in physical design to the initial core loading and shall have a maximum enrichment of 4.25 weight percent U-235.

CONTROL R0D ASSEMBLIES-5.3.2 The core shall contain 53 full-length and no part-length control rod

- assemblies. The full-length control rod assemblies shall contain a nominal 142 inches of absorber material. All control rods shall be hafnium, silver-indium-cadmium, or a mixture of both types. All control rods shall be clad with stainless steel tubing.

5.4 REACTOR COOLANT SYSTEM 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, with allowance for normal degradation pursuant to 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 680'F.

l VOLUME 5.4.2 The total volume of the Reactor Coolant System, including pressurizer and surge line, is 12,135 1 100 cubic feet at a nominal Tavg of 557*F.

5. 5 METEOROLOGICAL TOWER LOCATION 5.5.1 The meteorological tower shall be located as shown on Figure 5.1-1.

DESIGN FEATURES 5.6 FUEL STORAGE CRITICALITY 5.6.1.1 The spent fuel storage racks are designed and shall be maintained with:

A kfff equivalent to less than or equal to 0.95 when flooded with a.

unborated water, which includes a conservative allowance of 2.6%

ok/k for uncertainties as described in Section 4.3 of the FSAR..

This is based on new fuel with an enrichment of 4.25 weight percent

.l l

U-235 in Region 1 and on spent fuel with combination of initial enrichment and discharge exposures, shown in Figure 3.9-1, in

{

Region 2, and j

b..

A nominal 9.24 inch center-to-center distance between fuel' assemblies placed in the storage racks.

5. 6.1. 2 The k,7f for new fuel for the first core loading stored dry in the l

spent fuel storage racks shall not exceed 0.98 when aqueous foam moderation is

assumed, i

DRAINAGE 5.6.2 The spent fuel storage pool is' designed and shall be maintained to prevent inadvertent draining of the pool below elevation 2040 feet.

t CAPACITY 5.6.3-The spent fuel storage pool is designed and shall be maintained with a storage capacity limited to no more than 1344 fuel assemblies.

5.7 COMPONENT CYCLIC OR TRANSIENT LIMIT 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.
