FIGURE 3.9-2 MINIMUM REQUIRED FUEL ASSEMBLY BURNUP AS A OF INITIAL ENRICHMENT TO PERMIT STORAGE IN REGION 3 SU'DIER - UNIT 1 3/4 9-16 Amendment No. 27 /, -M-116

DESIGN FEATURES 5.3 REACTOR CORE FUEL ASSEMBLIES ~

5.3.1 The core shall contain 157 fuel assemblies. Each fuel assembly shall consist of 264 Zircaloy-4 or ZIRLO(TM) clad fuel rods with an initial composition of uranium dioxide with a maximum nominal enrichment of 5.0 weight percent U-235 as fuel material. Limited substitutions of Zircaloy-4, ZIRLO(TM) and/or stainless steel filler rods for fuel rods, if justified by a cycle specific reload analysis using an NRC-approved methodology, may be used. Fuel assembly configurations shall be limited to those designs that have been analyzed with applicable NRC staff-approved codes and methods, and shown by tests or cycle-specific reload analyses to comply with all fuel safety design bases. Reload fuel shall contain sufficient integral fuel burnable absorbers such that the requirements of Specifications 5.6.1.la.2 and 5.6.1.2 b are met.

A limited number of lead test assemblies that have not completed representative testing may be placed in non-limiting core locations.

CONTROL R0D ASSEMBLIES 5.3.2 The reactor core shall contain 48 full length control rod assemblies.

The full length control rod assemblies shall contain a nominal 142 inches of absorber material. The nominal values of absorber material shall be 80 percent silver, 15 percent indium and 5 percent cadmium. 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 For a temperature of 650*F, except for the pressurizer which is c.

680*F.

VOLUME 5.4.2 The total water and steam volume of the reactor coolant system is t

9407 100 cubic feet at a nominal Tavg of 586.8'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 consist of 1276 individual cells, each of which accommodates a single assembly. The cells are grouped into 3 regions.

The spent fuel storage racks are designed and shall be maintained with a Keff less than or equal to 0.95 when flooded with unborated water, which includes conservative allowances for uncertainties and biases.. This is ensured by maintaining the following for each region:

a.

REGION 1 - designated for storage of fresh fuel assemblies and freshly discharged fuel assemblies.

1.

A nominal 10.4025 inch center-to-center distance between fuel assemblies placed in the storage rack.

2.

A maximum nominal enrichment of 5.0 weight percent U-235 with sufficient integral fuel burnable absorbers such that the maximum reference fuel assembly K. is less than or equal to 1.460 at 68'F.

b.

REGION 2 - designated for storage of discharged fuel assemblies.

1.

A nominal 10.4025 x 10.1875 inch center-to-center distance between fuel assemblies placed in the storage rack.

i 2.

A maximum nominal enrichment of 2.5 weight percent U-235 with no burnup and up to 5.0 weight percent U-235 with a minimum burnup of up to 21,600 MWD /MTU, as specified in Figure 3.9-1.

c.

REGION 3 - designated for storage of discharged fuel assemblies.

1.

A nominal 10.116 inch center-to-center distance between fuel assemblies placed in the storage rack.

2.

A maximum nominal enrichment of 1.4 weight percent U-235 with no burnup and up to 5.0 weight percent U-235 with a minimum burnup of up to 48,000 MWD /MTV, as specified in Figure 3.9-2.

5.6.1.2 The new fuel storage racks consist of 60 individual cells, each of which accommodates a single assembly. The new fuel pit storage racks are designed and shall be maintained with a Keff less than or equal to 0.95 when flooded with unborated water and less than or equal to 0.98 for low density optimum moderation conditions, including conservative allowances for uncertainties and biases. This is ensured by maintaining:

a.

A nominal 21 inch center-to-center distance between new fuel assemblies placed in the storage rack.

b.

A maximum nominal enrichment of 5.0 weight percent U-235 with sufficient integral fuel burnable absorbers such that the maximum reference fuel assembly K. is less than or equal to 1.460 at 68'F.

SUMMER - UNIT 1 5-7 Amendment No. 27,--74,116

DESIGN FEATURES DRAINAGE l

5.6.2 The spent Yuel pool is designed and shall be maintained to prevent inadvertent draining of the pool below elevation 460'3".

CAPACITY 5.6.3 The spent fuel pool is designed and shall be maintained with a storage capacity limited to no more than 1276 fuel assemblies, 242 in Region 1, 99 in Region 2, and 935 in Region 3.

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.
