Operational Facts

THE MOX FUEL FABRICATION FACILITY PROCESS

The MOX Process is a mechanical process for transforming plutonium (Pu) from nuclear weapons into a mixed-oxide fuel similar to the uranium used in commercial power generating reactors throughout the world. Powdered plutonium and uranium oxide are mixed into a precise blend and pressed into a pellet about the size of a pencil eraser. The MOX facility, once it is running at full capacity, will produce upward of 50,000 to 70,000 pellets each day, each of which will be inspected to verify dimensions, density, markings, and appearance.

Approximately 300-350 of these pellets are arranged and inserted into a zirconium alloy tube: the fuel rod. The new fuel rod, in turn, is combined with 263 other rods and arranged into a fuel assembly, in a 17x17 array, about 13 feet long and weighing 1,500 pounds. These arrangements can be altered to meet the specifications of pressurized water reactors, boiling water reactors, and soon, new generations and designs of reactors.
