General Atomics last week celebrated the completion of the central solenoid modules for the ITER reactor being built in southern France. Designed to demonstrate the scientific and technological feasibility of fusion power, the ITER tokamak will be the world’s largest experimental fusion facility.

Demonstrating the beneficial reuse of equipment among Department of Energy cleanup sites, the DOE’s Office of Environmental Management transferred TRUPACT-III shipping equipment from its Savannah River Site in South Carolina to the Idaho Cleanup Project at the Idaho National Laboratory Site. This collaboration shows how DOE-EM drives efficiency, focusing on priorities and reining in costs without sacrificing safety or effectiveness, the DOE said.

Kairos Power and BWX Technologies announced today that they will work together to “collaboratively explore” optimizing commercial production of TRISO fuel for Kairos’s planned advanced reactor fleet—beginning with the 50-MWe Hermes 2, slated for operation in 2030—and other potential customers. Their collaboration could include jointly developing a TRISO fuel fabrication facility.

Eight days after Aalo Atomics released the details of its securing of $100 million in Series B funding, the company announced that it has broken ground on the 50-MWe Aalo-X. Sited in the desert beside Idaho National Laboratory, it will be the company’s first nuclear power plant, and it remains on track to go on line by July 4, 2026.

After the Trump administration’s new push to get a nuclear reactor on the moon by 2030 was first reported by Politico last month, media played up the shock value for people new to the concept. Few focused on the technical details of the new plan for lunar fission surface power (FSP), which halts and replaces a program that began under the first Trump administration with an early hope of getting a reactor on the moon by the end of 2026. Now, the focus is on streamlining NASA’s internal processes to support commercial space companies that can build a reactor with more than twice the power and mass and have it ready for launch by 2030.

The Nuclear Regulatory Commission has found that the environmental impacts of renewing the operating licenses of the Peach Bottom and Browns Ferry nuclear power plants for an additional 20 years are not great enough to prohibit doing so. If renewed, the licenses will allow the plants to operate for up to 80 years.

In May, the Wendelstein 7-X stellarator in Greifswald, Germany, concluded an experimental campaign by sustaining a plasma with a high triple product for 43 seconds. The machine far surpassed its own previous performance with a value that the Max Planck Institute for Plasma Physics (IPP) says “exceeds previous tokamak records for long plasma durations”—in part because of a fuel pellet injection system developed by researchers at Oak Ridge National Laboratory.
Watch ORNL’s video of that fuel pellet injection system—in use since September 2024—as it extrudes a column of frozen hydrogen and then cuts individual 3.2-millimeter-long pellets. The process, which takes just half a millisecond, was captured in slow motion by ORNL engineer Steve Meitner.
