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 l
5.3.1 The reactor shall contain 193 fuel assemblies.
Each assembly shall consist of a matrix of cylindrical ZIRLO or Zircaloy-4 clad fuel rods with an l
initial composition of natural or slightly enriched uranium dioxide (U0 ) as fuel material.
Limited substitutions of zirconium alloy or stainless sleel filler rods for fuel rods, in accordance with NRC-approved applications of fuel rod 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 f
shall be similar in physical design to the initial core loading and shall have q
a maximum er.richment of 5.0 weight percent U-235.
faRTf0L R0D ASSEMBilff 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 noa.inal values of absorber material shall be 80% silver,15%
indium, and 5% cadmium. All controi 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 requirement: 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.
y0LUME 5.4.2 The total water and steam volume of the Reactor Coolant System is 12,255 cubic feet at a nominal T, of 588.5'F.
