Sequoyah Fuels Corporation

Sequoyah Fuels Corporation owned and operated a uranium processing plant near Gore, Oklahoma. The company was created in 1983 as a subsidiary of Kerr-McGee. In 1988 it was sold to General Atomics.

Uranium processing plant
The plant is located near Gore, Oklahoma, close to the Illinois River and Interstate 40. The plant started construction in 1968 and began operation in 1970. It converted yellowcake uranium into uranium hexafluoride. In 1987 it started converting depleted uranium hexafluoride into depleted uranium tetrafluoride. The plant ceased operation in 1993. A leak and explosion in 1986 left one worker dead and extreme groundwater and soil contamination across the 600-acre site.

The plant was operated under Kerr-McGee Nuclear Corporation. In 1983 KMNC split into Quivira Mining Corporation and Sequoyah Fuels Corporation. The latter was given control of the plant. In 1988 Sequoyah Fuels Corporation was sold to General Atomics.

In 2008 a company named International Isotopes said it would buy equipment and intellectual property from the Sequoyah Fuels Corp plant. The equipment would be used in a new location. It would be used for converting depleted uranium hexafluoride to depleted uranium tetrafluoride.
