Nuclear Management Co. of Hudson, Wis., will pay USEC Inc. $130 million for separative work units contained in enriched uranium fuel.

The new contract, which runs from 2007 to 2013, covers NMC’s five nuclear reactors, USEC said Monday in a news release.

USEC said the new contract is a vote of confidence in its decision to switch from a gaseous diffusion technology to the American Centrifuge technology.

USEC buys highly enriched uranium taken from dismantled Russian nuclear warheads and turns it into low-enriched uranium fuel that is then sold to U.S. utility customers like Nuclear Management Co.
