The funding will support\nwork by Southern Company, Idaho National Laboratory and CORE POWER to advance\nscientific understanding of molten salt reactor technology and inform future\nreactor development. MCRE is expected to achieve first criticality as early as\n2027.\n\nMCRE is designed to become the world's first fast-spectrum molten chloride\nsalt reactor experiment to reach criticality, marking a historic step in the\ndevelopment of advanced nuclear technology. The experiment is expected to\ngenerate critical data on the behavior of the fuel, reactor operation and\nperformance, providing the scientific and engineering foundation needed to\nsupport future reactor design, licensing pathways and commercial deployment.\nBy reducing technical risk and expanding industry understanding of\nfast-spectrum molten salt systems, MCRE is expected to accelerate innovation\nacross a range of reactor developers.\n\nJess Gehin, associate laboratory director for Nuclear Science & Technology at\nIdaho National Laboratory, said:\n\n\"MCRE will be the world's first fast-spectrum molten chloride reactor to\nachieve criticality. It will provide direct measurements of how this novel\nreactor behaves during sustained fission, data that until now, has come from\nmodels alone. Enhancing those models with real-world operating evidence will\nreduce uncertainty for future reactor designers and regulators.\"\n\nMCRE demonstrates how industry, government and research institutions can work\ntogether to advance complex technologies, align expertise and resources, and\nmove promising science from the laboratory toward real-world applications.\n\nDr. Mark S. Berry, Southern Company senior vice president of research,\nenvironment and sustainability, said:\n\n\"Public-private partnerships play an essential role in advancing energy\ntechnologies from concept to demonstration. Through collaboration among DOE,\nIdaho National Laboratory and industry partners, MCRE will help expand\nknowledge of molten salt reactor technology and help reduce technical\nuncertainty for future developers. This type of collaboration allows\norganizations to share expertise, accelerate innovation and evaluate\ntechnologies that could help meet growing energy demand while supporting\nreliable, affordable energy for customers and communities.\"\n\nFast-spectrum molten salt reactors have the potential to transform far more\nthan electricity generation. From powering industrial processes and producing\nlife-saving medical isotopes to enabling future maritime propulsion and\nextracting additional value from used nuclear fuel, the technology could\nunlock a new generation of nuclear energy applications.*\n\nMikal Bøe, CEO of CORE POWER, said:\n\n\"New nuclear, like any truly transformative technology, requires vision and\nbeing in it for the long game. We first committed to building MCRE in 2020,\nand we are proud to now accelerate this world-first nuclear fuel cycle to\ncriticality as early as 2027. The data generated by this unique experiment\nwill help determine how we develop engineering, licensing and an entirely new\nsupply chain to practical commercial deployment of fast-spectrum molten salt\nreactors. CORE POWER's role in this partnership is to help translate advanced\nreactor technology into deployable industrial systems and unique delivery\nmechanisms needed to realize the potential of this technology.\n\n\"Merging the pathway of novel nuclear fuel cycle development that MCRE\nrepresents with CORE POWER's pathway of maritime nuclear development, creates\nunique opportunities to deliver an ultimately sustainable nuclear fuel\nsolution to new markets around the world. One such market is a sustainable\nfuture of civil maritime nuclear propulsion of large commercial ships, where\nan enduring, zero-emission power source can transform the way global trade is\ntransported at sea.\"\n\nNotes to editors\n\n* Depending on their design and fuel-cycle configuration, future fast-spectrum\nmolten salt reactors could use actinides recovered from spent nuclear fuels to\nextract more energy from existing nuclear material and reduce the volume and\nlongevity of waste requiring final disposal. Some configurations could also\nsupport fuel breeding and medical isotope production, as well as advances in\ncutting-edge chemistry and advanced materials. These are potential future\ncapabilities; MCRE itself will not use spent fuel, demonstrate a closed fuel\ncycle or test a marine reactor.\n\nBecause the fuel is dissolved in liquid chloride salt, future systems could\npotentially recycle long-lived and minor actinides without repeatedly\nmanufacturing new solid fuel assemblies.\n\nAbout Southern Company\n\nSouthern Company (NYSE:SO) is a leading energy provider serving 9 million\ncustomers across the Southeast and beyond through its family of companies.
