Project Objectives To support US pressurized water reactor transitions to 24 month refueling cycles, Westinghouse is pursuing an increase in allowable U235 enrichment (>5 wt%) at the Columbia Fuel Fabrication Facility (CFFF) site located in Hopkins, SC.
Westinghouse will construct a new building adjacent to the existing facility to produce fuel assemblies greater than the existing license requirements of 5 wt%.
The new building will operate at up to 8 wt%. No changes to the existing fuel factory.
The expansion and processes for 8 wt% will require prior NRC approval of the License Amendment Request to the CFFF Special Nuclear Material License (SNM-1107) per 10 CFR 70.72.
