DESIGN FEATURES

.e 5.3 REACTOR CORE FUEL ASSEMBLIES 5.3.1- The reactor core shall contain 157 fuel assemblies with each fuel assembly

- containing 264 fuel rods clad with Zircaloy -4. Each fuel rod shall have a

' nominal active-fuel. length of 144 inches and contain a maximum total weight of 1766 grams uranium. The initial core loading shall have a maximum enrichment of 3.2 weight percent U-235. Reload fuel shall be similar in physical design to the initial core loading and shall have a maximum enrichment of 4.3 weight percent U-235.

CONTROL ROD ASSEMBLIES 5.3.2 ~The reactor core shall contain 48 full length and no part 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 stecl tubing.  !

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, i

b. For a pressure of 2485 psig, and
c. For a temperature of 650*F, except for the pressurizer which is 680*F.
