Centrus Energy to Supply HALEU Fuel to Antares Nuclear, Enabling Micro Nuclear Reactor Applications for Military and Space

U.S. nuclear fuel supplier Centrus Energy has signed a multi-year contract with advanced microreactor developer Antares Nuclear, under which Centrus will supply high-assay low-enriched uranium (HALEU) to Antares. This agreement is expected to expand the application scenarios of micro nuclear reactors to locations where traditional power sources are difficult to use, such as military facilities and space environments. As part of the agreement, Antares Nuclear will make advance payments to support Centrus in expanding HALEU production capacity in the United States. Compared with conventional low-enriched uranium, HALEU contains more uranium-235, with an enrichment level above 5% but below 20%. This new type of fuel can support smaller, higher-energy-density reac...

Antares Wins U.S. Air Force Space Nuclear Energy Technology Contract

Antares recently announced that it has received a Strategic Breakthrough Award from the Office of the Assistant Secretary of the Air Force for Space Acquisition and Integration to advance space nuclear energy technology development. The company said this is currently the largest contract awarded by the U.S. War Department in the field of space nuclear energy. Antares CEO and co-founder Jordan Bramble said that space applications have been a core focus since the company's founding, and that cooperation with the Space Force has turned related concepts into formal space missions. He said nuclear fission technology is expected to provide space missions with strategic capabilities that are currently difficult to achieve. Under the project arrangement, Antares will carry out a ground nuclear power demonstration of the R1-S reactor...

US Antares Selected for DOE Nuclear Energy Launch Pad Program

Antares has been selected for the U.S. Department of Energy (DOE) Nuclear Energy Launch Pad program. Led by the DOE Office of Nuclear Energy and the National Reactor Innovation Center (NRIC), the program aims to advance nuclear technologies from concept to commercial deployment. This selection further expands Antares' business footprint in Texas. Previously, the company was selected to deliver a microreactor to Joint Base San Antonio under the U.S. Air Force's Advanced Nuclear Power Facilities program. Antares CEO and co-founder Jordan Bramble stated that the reactor pilot program has accelerated the company's growth and...

Antares and Standard Nuclear Sign Multi-Year TRISO Fuel Supply Agreement

Antares Nuclear, Inc. of the United States recently announced that it has signed a binding multi-year fuel supply agreement with Standard Nuclear to secure advanced nuclear fuel supply for its compact microreactor program. Under the agreement, Standard Nuclear will supply up to 8 metric tons of uranium (MTU) of tristructural isotropic particle fuel, or TRISO fuel, to Antares Nuclear by 2035. This fuel will be used in the microreactor currently being developed by Antares. Designed for demanding operating environments such as ground-based and space applications, this class of reactors aims to provide reliable power for national defense, aerospace, and off-grid critical infrastructure...

Uzbekistan Prepares for Second Nuclear Power Plant Project

Uzbek President Shavkat Mirziyoyev said on August 17 at a ceremony launching investment projects in the Khorezm region that Uzbekistan is carrying out large-scale preparatory work for the construction of a second nuclear power plant. This marks the first time the country has publicly mentioned the second NPP project. Mirziyoyev said Uzbekistan has advanced a number of energy and infrastructure projects in recent years, with the nuclear power plant under construction in the Jizzakh region being one of them. He noted that the second NPP is still in the preparation stage, with the project site, installed capacity, construction timeline, and potential contractors yet to be announced. At the same event, U...

Romania Declares National State of Emergency for August Amid Decline in Power Generation

Romania's Acting Prime Minister and Energy Minister Ilie Bolojan announced on July 31 after a cabinet meeting that Romania would enter a national state of emergency in August due to a decline in power generation caused by drought. Bolojan stated that the drought has reduced water levels in rivers, with a notable decrease in the flow of the Danube River. The flow has dropped from over 4,000 cubic meters per second to 1,600 cubic meters per second. He said that as a result, the water level in the intake basin of the Cernavodă NPP has fallen, and Unit 1 of the plant had to be shut down recently. He also noted that Unit 2 of the Cernavodă NPP faces a high risk of shutdown. Should Unit 2 go offline, Romania's total...
