You could call it a power contest. Teams picked for a new research program from the Defense Advanced Research Projects Agency (DARPA) will compete to design radiovoltaic cells that can outperform others in measured power density and endure high-flux radiation from a U.S. Army Research Lab linear accelerator. The top teams will strive to make it through a second downselect based on the performance of cells sequestered in time capsules and subjected to even more punishing high-flux radiation. Concepts that make it to the bonus period have a chance to be built into radioisotope-fueled power systems uniquely suited to high-radiation regions of space or dark, remote places on Earth.

Paragon Energy Solutions has signed a memorandum of understanding with Terra Innovatum, a developer of micro-modular nuclear reactors, to support the design and integration of instrumentation and control systems for Terra’s Solo micro-modular reactor. Paragon is a provider of safety-related I&C systems for the nuclear energy community.

Husband-and-wife team Timothy Adkins and Ann Gibeaut are using Geiger counters supplied by the American Nuclear Society to educate young people in West Virginia about nuclear science and ionizing radiation. In 2022, ANS donated some old nonfunctioning Geiger counters to Tim and Ann, who recalibrated them and got them working again.

Rafael Mariano Grossi, director general of the International Atomic Energy Agency, has shared his concerns about the Iran-Israel conflict with the agency’s board of directors.
“Military escalation threatens lives, increases the chance of a radiological release with serious consequences for people and the environment and delays indispensable work towards a diplomatic solution for the long-term assurance that Iran does not acquire a nuclear weapon,” Grossi said on June 16. “Consistent with the objectives of the IAEA and its statute, I call on all parties to exercise maximum restraint to avoid further escalation.”

Susquehanna nuclear power plant in Salem Township, Pa.
Talen Energy Corporation and Amazon have signed an expanded power purchase agreement (PPA) whereby Talen agrees to supply electricity from its Susquehanna nuclear power plant for AI operations and other cloud technologies at Amazon Web Services’ data center campus next to the power plant.

The Massachusetts Institute of Technology’s Plasma Science and Fusion Center (PSFC) has launched the Schmidt Laboratory for Materials in Nuclear Technologies (LMNT). Backed by a philanthropic consortium led by Eric and Wendy Schmidt, LMNT is designed to speed up the discovery and evaluation of cost-effective materials that can withstand extreme fusion conditions for extended periods.

The Nuclear Regulatory Commission is providing the opportunity to request a hearing on Dow Chemical Company’s application to construct a 320-MWe nuclear power plant at the company’s Seadrift site in Calhoun, Texas. Long Mott Energy, a wholly owned subsidiary of Dow Chemical, submitted its construction permit application to the NRC in March. It was accepted for review by the agency on May 12.

It’s a move that “brings to an end decades of dithering and delay, with the government backing the builders.” That’s how the U.K. government announced, with alliterative fanfare, its £14.2 billion (about $19.2 billion) investment in Sizewell C, where EDF Energy plans to build two 1,600-MWe EPRs.

Rolls-Royce SMR has emerged as the United Kingdom’s preferred bidder to build the country’s first small modular reactors following a two-year competition, the U.K. government announced June 10. Rolls-Royce SMR expects to build three SMRs with Great British Energy–Nuclear, subject to contracting later this year and regulatory approvals. Great British Energy–Nuclear will “aim to allocate a site later this year and connect projects to the grid in the mid-2030s.”
