The Y-12 National Security Complex in Oak Ridge manufactured the uranium reactor core for a federal experiment that tested whether a nuclear energy source could provide power for space exploration.

“The full-power run showed that it may be feasible for NASA to use small fission reactors for deep space exploration and manned missions to the moon and Mars,” the National Nuclear Security Administration said in May.

The NNSA, which is part of the U.S. Department of Energy, worked with NASA (the National Aeronautics and Space Administration) on the project. It’s nicknamed KRUSTY, an acronym for Kilowatt Reactor Using Stirling Technology.

“In a joint venture with NASA last year, NNSA completed final design, fabrication, and full-power testing of a nuclear criticality experiment that can be used for a manned lunar or Mars space mission,” NNSA Administrator Lisa Gordon-Hagerty said in a post published on Twitter on Friday.

The uranium reactor core from Y-12 was delivered to the National Criticality Experiments Research Center at the Nevada National Security Site in the fall of 2017. [Read more…]

The Y-12 National Security Complex is taking their uranium expertise to the next level—outer space.

The NNSA Production Office (NPO) at Y-12 struck an agreement earlier this year with NASA’s Glenn Research Center in Cleveland, Ohio, to support the design of a small nuclear-powered reactor with the potential to lead to small fission power reactors for future space exploration missions.

For the first phase of the project, Y-12 will research materials and manufacturing processes for a physics demonstration of a kilowatt-range nuclear reactor, known as project Kilopower, using an enriched uranium-molybdenum metallic fuel core and a lithium-hydride shield. The Kilopower concept was a 2013 R&D 100 Award winner for proof-of-principle experiments performed at the National Criticality Experiments Research Center in Nevada led by Los Alamos National Laboratory in collaboration with NASA Glenn and National Security Technologies.

“Science missions are seeking greater power and functionality,” explained Lee Mason, chief of the Thermal Energy Conversion Branch at Glenn. “We’re planning to demonstrate the technology in a ground test using a prototype U-235 reactor core.” [Read more…]
