Paramilitary security contractor Centerra won 97% or about $3.17 million out of a potential $3.26 million fee for protecting the Energy Department’s Savannah River Site in South Carolina during the second half of fiscal 2019, which ended Sept. 30. That’s according to a scorecard released by DOE over the winter holidays for Centerra-Savannah River Site. […]

The National Nuclear Security Administration’s plan to produce 80 pits a year would generate more than 1,110 cubic meters of transuranic waste a year, according to an environmental review the semiautonomous Department of Energy weapon steward released this week. Over 50 years — enough time at an 80-a-year throughput to produce two new pits, and […]

The National Nuclear Security Administration plans a somewhat expedited environmental review of its plan to convert a partially built plutonium recycling plant at the Savannah River Site in Aiken, S.C., into a plutonium-pit factory, according to a decision posted online this week. The agency has studied since June whether it must complete a brand new environmental […]

The power substation that will route electricity to the Uranium Processing Facility in Oak Ridge, Tenn., is finished, the National Nuclear Security Administration said. The Tennessee Valley Authority designed and built the $60 million substation, the semiautonomous Department of Energy nuclear weapons agency wrote in a press release on Monday. Aspects of the substation have irked […]
