A deep learning model developed by Lawrence Livermore National Laboratory scientists is proving more accurate and efficient than conventional simulations in predicting fusion experiment results. Drawing on past experimental data, high-fidelity physics simulations and expert insights, it accounts for real-world imperfections to deliver rapid, probabilistic forecasts across a wide range of parameters. The model correctly predicted ignition in a 2022 National Ignition Facility test and has since been used to optimize limited and costly experimental runs.

In his new book, "Going Nuclear," nuclear chemist Tim Gregory champions nuclear energy as the most reliable, efficient and environmentally compact solution for combating climate change. In a conversation with Big Think, he dispels common misconceptions about nuclear waste, noting that its volume is small, much of it can be recycled into fuel and it contains isotopes valuable for medicine and space exploration. "Things can go wrong of course, but nuclear reactors are cleverly designed so that that doesn't happen very often, which is demonstrated by nuclear's impeccable safety record," Gregory says.

The Nuclear Regulatory Commission and NextEra are maintaining rigorous oversight of alkali-silica reaction, also known as "concrete cancer," at the Seabrook nuclear plant in New Hampshire, the only US reactor where the issue has been identified. Since its discovery in 2010, the degradation has been closely tracked through expanded inspections, laboratory testing and license amendments to keep the plant within approved operating parameters. A large-scale test program at the University of Texas at Austin helped develop monitoring techniques and establish expansion limits, now integrated into the plant's licensing basis.

Advancements in nuclear medicine will require updates in patient radiation protection policies, according to experts at a recent International Atomic Energy Agency meeting. The development of new radiopharmaceuticals and imaging technologies is increasing the number and variety of procedures, highlighting the need for updated guidelines and safety protocols.

A former nuclear site in the UK will become a hub for nuclear medicine and fusion fuel, creating up to 1,000 jobs. Astral Systems will produce radioisotopes for targeted radiotherapy, addressing the UK's current reliance on imported isotopes, while Quantum Leap Energy will focus on manufacturing fusion fuel.

In the latest episode of the Shift Key podcast, host Jesse Jenkins of Princeton University and Robinson Meyer discuss the intricacies of US wholesale power markets. They explain how electricity is priced in real time, the concept of economic dispatch and the role of marginal generators. The episode also addresses the challenges of encouraging the construction of new power plants and the impact of power markets on renewable energy integration.

The Swiss government has proposed ending its 2018 ban on new nuclear power plants, a policy shift that would allow companies to apply for reactor construction licenses. Officials say the legislative solution, still subject to parliamentary review and voter approval, offers a faster route than the constitutional change sought by the "Stop the Blackout" initiative.

Data center developer Equinix has announced a series of deals with advanced nuclear developers to secure more than 1 gigawatt of future power capacity for its operations. The agreements include a 500-megawatt deal with Oklo, a preorder for 20 microreactors from Radiant Nuclear and partnerships in Europe with ULC-Energy and Stellaria.
