DESIGN FEATURES DESIGt PRESSURE AND TEMPERATURE  !

i 5.2.2 The containment building is designed and shall be maintained for a '

maximum internal pressure of 52.0 psig and a temperature of 296 F.

5.3 REACTOR CORE l

FUEL ASSEMBLIES 5.3.1 The reactor shall contain 193 fuel assemblies. Each assembly shall consist of a matrix of cylindrical zircaloy clad fuel rods with an initial  !

composition of natural or slightly enriched uranium dioxide (U0d as fuel i material. Limited substitutions of zirconium alloy or stainless steel filler ,

rods for fuel rods in accordance with NRC-approved applications of fuel rod I configurations, may be used. Fuel assemblies shall be limited to those fuel designs that have been analyzed with applicable NRC staff-approved codes and methods and shown by tests or analyses to comply with all fuel safety design bases. A limited number of lead test assemblies that have not completed representative testing may be placed in nonlimiting core regions. Reload fuel l shall be similar in physical design to the initial core loading and shall have l a maximum enrichment of 5.0 weight percent U-235.

CONTROL ROD ASSEMBLIES l 5.3.2 The core shall contain 57 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% silver 15%

indium, and 5% 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:

l 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 l 6B0 F.

! VOLUME 5.4.2 The total water and steam volume of the Reactor Coolant System is 12.255 cubic feet at a nominal Tm of 588.5 F.

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