<\/a><\/a>\nIn May 2025, the Administration issued executive orders to strengthen and accelerate the U.S. nuclear industry. Executive Order 14301 directed the DOE to bring at least three advanced reactor designs to criticality by July 4, 2026. Of the 11 projects initially selected, four achieved criticality \u2014 the ability to sustain a controlled nuclear chain reaction.<\/p>
\nAcross these efforts, Mirion Technologies and Paragon provided products, systems, and expertise spanning reactor protection, neutron flux monitoring, radiation monitoring, health physics, radiation protection and radiochemistry. These capabilities helped developers reach criticality safely and advance their projects.<\/p>
\nCongratulating the DOE, Idaho National Laboratory and Reactor Developers<\/b><\/p>
\nMirion congratulates the U.S. DOE, Idaho National Laboratory (INL) and the reactor developers on these landmark achievements. As host to a number of participating reactor efforts and a national leader in advancing reactor innovation, INL provided the infrastructure, expertise, and testing capability that helped make these milestones possible. The program\u2019s success reflects the shared commitment of the DOE, its national laboratories, and industry partners to demonstrating that the United States can develop and deploy advanced nuclear technology at pace.<\/p>
\n\u201cAchieving criticality is a defining milestone in advanced reactor development, and we are proud to support the teams building the next generation of nuclear energy,\u201d said Tighe Smith, Chief Nuclear Officer of Mirion and Paragon. \u201cWhat this program has shown is that an ambitious schedule is achievable when government, the national laboratories and industry work as one team toward a shared goal. That momentum is a real breakthrough. It proves we can move quickly and, importantly, safely sustain that pace as advanced nuclear moves from demonstration toward broad deployment.\u201d<\/p>
\nMirion Nuclear Solutions \u2014 Mirion Technologies, Paragon Energy Solutions and Certrec \u2014 provides integrated capabilities spanning reactor safety, radiation monitoring, regulatory compliance and operational readiness from demonstration to commercial deployment.<\/p>
