Antares achieves zero-power criticality at INL
Leveraging more than $140 million in private capital fundraising, over 322,000 square feet of operational manufacturing space, and multifaceted partnerships with the Departments of Energy and Defense, reactor start-up Antares has become the first company involved in the Reactor Pilot Program to achieve zero-power fueled criticality—a full month ahead of the July 4 deadline set by President Trump’s Executive Order 14301.
This milestone, announced yesterday, was achieved with the company’s Mark-0: a sodium heat-pipe-cooled, TRISO-fueled microreactor. The Mark-0 is a forerunner to the company’s flagship design, which it calls the R1. For Antares, this development represents a key validation of its reactor physics, control systems, and supply chain.
Nuclear and Emerging Technologies for Space (NETS-2024) Plenary SPeaker
Anastasia (Stacy) Mclaughlin is the Senior Director for Science, Technology, and Engineering Programs within the Weapons Production Directorate (ALDWP) at Los Alamos National Laboratory (LANL). The Laboratory is a principal contributor to the United States Department of Energy mission to maintain the nation’s nuclear weapons stockpile. LANL uses innovative science, technology, and engineering to enhance global nuclear security and protect the world. Los Alamos has an annual operating budget of approximately $3.9 billion, roughly 14,100 employees, and a 40-square-mile site featuring some of the most specialized scientific equipment and supporting infrastructure in the world.
As Senior Director, Stacy leads the non-defense nuclear programs within ALDWP to support national security and deep space endeavors. These programs provide world-class services in nuclear material research, process, and technology development and manufacturing capabilities that support nuclear non-proliferation, plutonium-238 science, manufacturing for NASA and Americium recovery occurring at the Los Alamos’s Plutonium Facility.
Stacy has over 25-years of technical and management experience working throughout the DOE/NNSA weapons complex in program and line management, quality engineering, non-destructive plutonium assay, plutonium processing and engineering, and hazardous waste management. She began her laboratory career as an undergraduate student at LANL in 1994, becoming a consultant, then a technical staff member, and advancing through multiple national security management positions to her present position.
Stacy earned a bachelor’s of science in Environmental Engineering from the University of California, Riverside, and a master’s of engineering in Chemical Engineering from the University of New Mexico.
Stacy is a native New Mexican, born and raised in Albuquerque, New Mexico. She enjoys sports including skiing and swimming and watching her four children compete in a variety of sports. She is an avid reader and enjoys hiking.
