Cimarron Fuel Fabrication Site

The Cimarron Fuel Fabrication Site was a nuclear fuel production facility located by the Cimarron River near Cimarron City, Oklahoma. It was operated by Kerr-McGee Corporation (KMC) from 1965 to 1975.

Some of the byproducts and waste from Kerr-McGee's Uranium and Thorium processing at its Cushing, Oklahoma refinery were transported to Cimarron in the 1960s.

In 1965 Kerr-McGee received a Nuclear Regulatory Commission license to make nuclear fuel at the plant. The NRC license numbers were SNM-928 for the Uranium production and SNM-1174 for mixed Plutonium-Uranium Oxide (MOX) production.

The plant made Uranium fuel and MOX driver fuel pins for use in the Fast Flux Test Facility at the Hanford Site in Washington State. Along with NUMEC, between 1973 and 1975 Kerr-McGee made the fuel pins for FFTF cores 1 and 2. The pins were quality tested by the Plutonium Finishing Plant at Hanford. The MOX pins were created by the unusual co-precipitation of Plutonium Nitrate and Uranium Nitrate solution method. The plant shut down in 1976.

In 1983 Kerr-McGee Nuclear split into Quivira Mining Corporation and Sequoyah Fuels Corporation, although both were still owned by Kerr-McGee. Sequoyah got the Cimarron plant. Sequoyah was then sold to General Atomics in 1988, but Kerr-McGee kept control of Cimarron under a subsidiary named the Cimarron Corporation. In 2005 Kerr-McGee formed a new subsidiary named Tronox, and it then gained ownership of Cimarron. Tronox was then spun off as an independent company in 2006, a few months before KMC was bought by Anadarko Petroleum. Tronox went bankrupt in 2008/2009, blaming in part the environmental debts it inherited from KMC. Tronox shareholders later sued Anadarko Petroleum (KMC's successor) for having misled investors.
