, ,,,. Docket Number 50-346 License Numbet NPF-3 Serial Number 1976 Attachment Page 6 Current Vording:

5.3.1 The reactor core shall contain 177 fuel assemblies with each fuel assembly containing 208 fuel rods clad with Zircaloy-4. Each fuel rod shall have a nominal active fuel length of 144 inches and contain a maximum total veight of 2500 grams uranium.

Reload fuel shall be similar in physical design to the initial core loading and shall have a maximum enrichment of 3.8 veight percent U-235.

Proposed Votding:

5.3.1 The reactor shall contain 177 fuel assemblics.

shall consist of a matrix of Zircaloy clad fuel rods with an initialEach assembly composition of natural or slightly enriched uranium dioxide (00 ) as fuel material, vith a maximum enrichment of 3.8 veight percent 7 U-235.

Limited substitutions of stainless steel filler tods for fuelinrods ,

accordance be used. with approved applications of fuel rod configurations, may Fuel assemblies shall be limited to those fuel designs that have been analyzed with applicable NRC Stati approved codes and methods and bases.shown by tests or analyses to comply with all fuel safety design Each fuel rod shall have a nominal active fuel length of 144 inchus and shall contain a maximum total veight of 2500 grams uranium .
