DESIGN FEATURES DESIGN PRESSURE AND TEMPERATURE b.2.2 The reactor containment building is designed and shall be maintained for t maximum internal pressure of 40 psig and a temperature of 264*F.

5.3 REACTOR CORE, FUEL ASSEMBLIES g y go,, , j p.

5.3.) The reactor core]shall contain 177 fuel assemblien. Each assembly snail consist of a matrix ofMhceley clad fuel rods w'.th an initial composition of natural or slightly enriched uranium dioxide (UO2) as fuel material, w44 a w>

Limited substitutions offstain-N P-C ' tess steel tiller roos for fuel roos, in accoraance with} 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 approvec codes and methods and shown by tests or anhlyses to comply with all fuel safety

5,3.2 The r: actor core shalT contain 53 safety ana reg 61ating contro: roa assemblic' (which :r=y be either standard or extenced life centrol rod assemblies) and 8 axial power shaping rod (APSR) assemblies. Standard control rods shall contain a nominal 134 inches of absorber material. The extended life control rods shell contain a nominal 139 inchts of absorber material ~ The nominal values of absorber material for the safety and regulating control rods shall be 80 percent silver.15 percent indium, and _

5 percent cadmium. Standard control rods and APSRs shall be clad with stain-less steel tubing. The extended life control rods shall be clad with Inconel.

The APSRs shall contain a nominal 63 inches of absorber material at their I lower enos. The absorber material for the APSRs shall be 100 percent Inconel.

5.4 REACTOR COOLANT SYSTEM f

DESIGN PRESSURE AND TEMPERATURE 5.4.1 The reacter coolant system is designed and shall be ma'.ntained:

a. In accordance with the code recuirements specified in Section 5.2 of the FSAR. with allowance for noreal degradation pursuant to applicable Surveillance Requirements. ,

b. For a pressure of 2500 psig, and

c. For a temperature of 650*F. except for the pressurizer and

,.ressurizer surge line wnich is 670*F.
