dc.title: Strengthening the Domestic Nuclear Supply Chain Through State-Level Action dc.description.abstract: The accelerating demand for reliable, clean baseload power in the United States, driven by population growth, electrification, and the rapid expansion of energy-intensive industries such as artificial intelligence and advanced manufacturing, has renewed policy interest in Small Modular Re…

IntroductionHydro-dominant power systems in Latin America are recurrently exposed to ENSO-driven hydrological scarcity, creating adequacy risks precisely when firm energy is most valuable.MethodsThis paper proposes a Monte Carlo-based methodology to accredit nuclear firm energy for small modular reactors (SMRs) under climatic stress, using an explicit stress-month definition derived from long-run…

Construction of an advanced nuclear power plant partly funded by the U.S. government -billed as the first of its kind this century, is now underway in Wyoming. The Bill Gates-backed company says its technology is proven but there are still hurdles to nuclear.

The Department of Energy’s Office of Nuclear Energy and the National Reactor Innovation Center have announced the first selections for the Nuclear Energy Launch Pad. Deployable Energy, General Matter, NuCube Energy and Radiant Industries were selected from an initial pool of Reactor Pilot Program and Fuel Line Pilot Program applicants, the two precursor programs to… The post DOE announces first s…

The U.S. Department of Energy‘s (DOE) Oak Ridge National Laboratory (ORNL) claimed the 2026 SME Aubin Additive Manufacturing Case Study Award at the SME AM Awards and TCT Awards Gala, held April 14 in Boston. The honor spotlights standout real-world deployments of 3D printing, and ORNL’s entry, focused on nuclear construction, impressed judges for its…

Small, modular nuclear fission reactors and fusion facilities could each be the future of resilient and secure energy in the U.S. and around the world.

A newly published custom collection of glass formulas for nuclear waste vitrification -- developed and validated by PNNL over the past three years -- was made possible in that timeframe with AI tools, including a PNNL machine learning model.

The fusion energy start-up Commonwealth Fusion Systems aims to bring its first power plant online by the early 2030s, but daunting technical hurdles remain

As electricity demand and geopolitical tensions rise, nuclear energy stands out as a crucial pillar in countries' energy security strategies. The post Nuclear energy for an era of rising demand and strategic risk appeared first on Atlantic Council .

With AMA: Energy 2026 just around the corner, 3D Printing Industry is taking a closer look at the role of additive manufacturing in the energy sector. Nuclear construction is slow, expensive, and resistant to change, a combination that has constrained the industry for decades. US largest multi program science and technology laboratory Oak Ridge National Laboratory is…

ORNL Wins 2026 SME Award for Using 3D Printed Molds to Speed Nuclear Reactor Construction April 28

Australia is dependent upon UK’s ability to deliver new submarines, but report finds ‘cracks are already beginning to show’ “Cracks are already beginning to show” in the UK’s funding for the Aukus agreement that could derail the ambitious nuclear submarine plan, a British parliamentary inquiry has found, highlighting a threat to Australia’s security. UK shipbuilding has been under-funded for deca…

President Trump keeps promising to secure Iran’s nuclear “dust,” which is actually a gas

A team from the Department of Energy's Oak Ridge National Laboratory has won the 2026 SME Aubin Additive Manufacturing Case Study Award, which recognizes outstanding real-world applications of 3D printing. ORNL's Manufacturing Demonstration Facility led the effort, using large-format additive manufacturing (LFAM) to create high-precision molds for advanced nuclear reactors. The work could help lo…

TerraPower is officially moving dirt on its facility in Wyoming, making it the first company in the U.S. to break ground on a next-generation nuclear plant. Read More

With AMA: Energy 2026 approaching, 3D Printing Industry is taking a closer look at the role of additive manufacturing in the energy sector. When most engineers think about the challenges of nuclear fusion, they think about plasma temperatures of 50 million degrees Celsius, magnetic containment, and tritium fuel cycles. Moataz Attallah, newly appointed Dean of…

It is essential for the safety assessment of a repository to analyze the release and transport of radionuclides from the near-field to the geosphere and subsequently to the surface environment. A new model has been developed in COMSOL Multiphysics based on input data from the safety case for the disposal of spent nuclear fuel at Olkiluoto. Complex processes, for example, nuclide decay, material c…

Evaluating the Influence of Surface Characteristics on Boiling and CHF Predictions with the MITB Model in Subcooled Flows Ding, Alice The MIT Boiling Model (MITB) offers a detailed physics-based alternative to the empirical, correlation-based approaches of subchannel codes which are still the nuclear industry standard while limited in general applicability. In contrast, MITB is designed for integ…

Verification of the ADDER Fuel Management Code for MITR-II Fuel Management Analysis Ahuactzin-Garcia, Emilio The Massachusetts Institute of Technology Reactor (MITR-II) is a 6 MWth research reactor with highly enriched uranium fuel. Due to the proliferation concerns of civilian HEU use, the MIT Nuclear Reactor Laboratory is actively participating in the US High Performance Research Reactor (USHPR…

NANO Nuclear Space Inc., a subsidiary of NANO Nuclear Energy, is designing a nuclear reactor for the Moon. James Walker, CEO of NANO Nuclear Energy, says they can get it there by 2030.  There are several challenges associated with a lunar reactor, Walker said. The payload has to be smaller for launch, the operation has… The post NANO Nuclear could have a reactor on the Moon by 2030 CEO says appea…
