CB&I Areva MOX Services LLC, a consortium including France’s state-owned Orano, formerly called Areva, has been building the Mixed Oxide (MOX) project at the Savannah River Site in South Carolina since 2007.

But the U.S. National Nuclear Security Administration told it in a letter dated Oct. 10 that the project was over. “This notice terminates the contract in its entirety, and is effective immediately,” said the letter, a copy of which was seen by Reuters.
