1 DESIGNFEATUJES 5.3 REACTOR CORE FUEL ASSEMBLIES  !

5.3;1 The reactor core shall contain 193 fuel assemblies. Each fuel assembly shall consist of a matrix of zircaloy or ZIRLO clad fuel rods with an initial composition of natural or slightly enriched uranium dioxide as fuel material.

Limited substituti'ons of zirconium alloy, ZIRLO or stainless steel 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 1 bases. A'11mited number of lead test assemblies that have not completed representative _ testing may be placed in non limiting core regions.

CONTROL ROD ASSEMBLIES 1

5.3.2 The core'shall contain 57 full-length control rod assemblies. The full-length control rod assemblies shall contain a nominal 156.9 inches of absorber material. The absorber material within each assembly shall be silver-indium-cadmium or hafnium. Mixtures of hafnium and silver-indium-cadmium are not permitted within a bank. All control rods shall be clad with stainless steel tubing.
