TerraPower and Southern Company to demonstrate the world’s first fast-spectrum salt reactor at Idaho National Laboratory
The Molten Chloride Reactor Experiment will provide crucial operational data for fast-spectrum salt reactors and unlock this uniquely flexible advanced reactor technology for use in a net-zero future
BELLEVUE, Washington – FEBRUARY 23, 2022 - TerraPower and Southern Company recently finalized a subrecipient agreement to design, construct and operate the Molten Chloride Reactor Experiment (MCRE) – the world’s first critical fast-spectrum salt reactor – at Idaho National Laboratory (INL).
“TerraPower is eager to continue its partnership with Southern Company – an established energy company that offers a crucial perspective and expertise to further position our Molten Chloride Fast Reactor technology for success,” said Chris Levesque, TerraPower’s president and CEO. “We are honored to be part of a team that is dedicated to advancing next-generation, low-cost, carbon-free nuclear technology to help meet global emissions-reduction targets and provide reliable power.”
Selected for funding under the U.S. Department of Energy’s (DOE) Advanced Reactor Demonstration Program (ARDP), the MCRE project will advance TerraPower’s Molten Chloride Fast Reactor (MCFR)— a technology that could provide low-cost, clean energy for a sustainable future. Southern Company research and development will lead the effort in a collaboration that includes TerraPower, INL, CORE POWER, Orano Federal Services, the Electric Power Research Institute and 3M Company. The team’s ongoing alliance with DOE’s Office of Nuclear Energy through the ARDP is essential for delivering this key technology and will be supported by a five-year, $170 million cost-shared funding agreement.
“Southern Company is honored to work with DOE, TerraPower, INL and our other team members to advance next-generation nuclear as part of a comprehensive strategy to deliver clean, safe, reliable, affordable energy to the customers and communities we serve,” said Dr. Mark S. Berry, Southern Company vice president of R&D. “The Molten Chloride Reactor Experiment will advance a revolutionary technology that promises to address climate change benchmarks on a timescale to deliver on Southern Company’s goal of net-zero greenhouse gas emissions by 2050.”
The Molten Chloride Reactor Experiment will be the world’s first fast-spectrum, salt-fueled nuclear fission reactor to go critical, meaning that it is operating on a self-sustaining nuclear chain reaction. The MCRE project represents a significant inflection point in the technology demonstration roadmap for TerraPower’s MCFR, as the project will inform the design, licensing and operation of an MCFR demonstration reactor. MCRE is targeted for operation at INL, the nation’s premier nuclear energy laboratory, and will be authorized by DOE.
The MCRE project will not generate electricity, but it will operate at a power of up to 500 kilowatts and demonstrate key physics performance important to the broader MCFR program. An environmental review will be completed for the MCRE project in accordance with the National Environmental Policy Act before final design and construction begin. MCRE first criticality is scheduled for late 2025.
TerraPower’s MCFR technology has the potential to provide low-cost, clean energy for the future. It offers many performance and economic benefits including flexible, highly efficient clean power generation as a complement to the increased use of intermittent renewables on the grid. The MCFR technology also has the potential to provide carbon-free, high-grade process heat and thermal storage for difficult-to-decarbonize industrial markets and ocean transportation sectors.
Through a public-private partnership that was initiated in 2015, Southern Company and TerraPower joined DOE and others in the nearly $80 million project building integrated infrastructure necessary to support early development of the MCFR technology. The newly selected Molten Chloride Reactor Experiment will further advance this development.
