BWX Technologies, Inc., will deliver the first microreactor in the United States under a contract awarded by the U.S. Department of Defense Strategic Capabilities Office (SCO), the company announced today. BWXT will have two years to build a transportable microreactor prototype to the SCO’s Project Pele specifications and deliver it to Idaho National Laboratory for testing under a cost-type contract valued at about $300 million.

X-energy has announced that its wholly owned subsidiary, TRISO-X, plans to build the TRISO-X Fuel Fabrication Facility, dubbed TF3, at the Horizon Center Industrial Park in Oak Ridge, Tenn. X-energy has produced kilogram quantities of fuel at its pilot plant at Oak Ridge National Laboratory through a public-private partnership.
The commercial plant will use high-assay low-enriched uranium (HALEU) to produce TRISO particles, which are fabricated into fuel forms, including the spherical graphite “pebbles” needed to fuel the company’s Xe-100 high-temperature gas reactor. Site preparation and construction are expected to get underway in 2022, and commissioning and start-up are scheduled for as early as 2025, according to X-energy.

X-energy, developer of the Xe-100 small modular reactor, has delivered the first of four sets of equipment for the Xe-100 reactor protection system (RPS) prototype, marking the latest milestone in the company’s efforts under the Department of Energy’s Advanced Reactor Demonstration Program (ARDP).

The U.S. Department of Defense (DOD) is looking to reduce its reliance on local electric grids and diesel-fueled generators at military installations. Project Pele is designed to demonstrate the technical and safety features of mobile microreactors capable of generating up to 5 MWe.

Nuclear thermal propulsion (NTP) is one technology that could propel a spacecraft to Mars and back, using thermal energy from a reactor to heat an onboard hydrogen propellant. While NTP is not a new concept, fuels and reactor concepts that can withstand the extremely high temperatures and corrosive conditions experienced in the engine during spaceflight are being designed now.
BWX Technologies announced on December 13 that it has delivered coated reactor fuels to NASA for testing in support of the Space Technology Mission Directorate’s NTP project. BWXT is developing two fuel forms that could support a reactor ground demonstration by the late 2020s, as well as a third, more advanced and energy-dense fuel for potential future evaluation. BWXT has produced a videoof workers processing fuel kernels in a glovebox.

X-energy and Centrus Energy announced last week that they have completed the preliminary design of the TRISO-X fuel fabrication facility and have signed a contract for the next phase of work. The planned facility would produce TRISO fuel particles and pack those particles into fuel forms, including the spherical graphite “pebbles” needed to fuel X-energy’s Xe-100 high-temperature gas reactor.

Global First Power’s (GFP) Micro Modular Reactor (MMR) project has moved to the formal license review phase with the Canadian Nuclear Safety Commission (CNSC), becoming the first small modular reactor to do so.
