Plastic waste is polluting the oceans and entering the human body in the form of microplastics. According to the United Nations, without immediate action the amount of plastic finding a way into the oceans each year could reach 37 million metric tons by 2040, becoming a threat to marine and human life.

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.

Trio of GAIN vouchers for sensors, materials, and fuels testing

June 6, 2025, 7:01AMNuclear News

The Department of Energy announced on June 5 that three companies—all of which are new to the Gateway for Accelerated Innovation in Nuclear (GAIN) voucher program—will receive vouchers to support their research on advanced fuels, materials, and sensors. The second round fiscal year 2025 vouchers will let the companies access specialized research facilities and expertise in the DOE’s national laboratory complex.

Argonne creates new methodology for digital twins

Argonne National Laboratory has added a new twist to digital twin technology for research into nuclear energy. According to Rui Hu, a principal nuclear engineer at Argonne, “Our digital twin technology introduces a significant step toward understanding and managing advanced nuclear reactors, enabling us to predict and respond to changes with the required speed and accuracy.”

The research of Hu and his colleagues, “Development of Whole System Digital Twins for Advanced Reactors: Leveraging Graph Neural Networks and SAM Simulations,” was published in the American Nuclear Society journal Nuclear Technology.

Virtual representation: A digital twin technology is an accurate virtual representation of a complex system. It is updated with real-time data from sensors applied to the physical system, such as a nuclear reactor.

Curiosity landed on Mars sporting a radioisotope thermoelectric generator (RTG) in 2012, and a second NASA rover, Perseverance, landed in 2021. Both are still rolling across the red planet in the name of science. Another exploratory craft with a similar plutonium-238–fueled RTG but a very different mission—to fly between multiple test sites on Titan, Saturn’s largest moon—recently got one step closer to deployment.

On April 25, NASA and the Johns Hopkins University Applied Physics Laboratory (APL) announced that the Dragonfly mission to Saturn’s icy moon passed its critical design review. “Passing this mission milestone means that Dragonfly’s mission design, fabrication, integration, and test plans are all approved, and the mission can now turn its attention to the construction of the spacecraft itself,” according to NASA.

Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.
