Restarting a Nuclear Reactor: Three-Mile Island’s Workforce and Legal Challenges Guest Blog Post by: Elliot Marsh, NeutronRise This is a summary of the full report.Full text of the report The big picture: Constellation Energy is executing a fast-track effort to bring Three-Mile Island Unit 1—renamed the Crane Clean Energy Center—back online by late 2027. Backed by a 20-year power purchase agreement with Microsoft and a $1 billion federal loan closed in November 2025, the project represents the leading edge of a new discipline: returning a retired cold, defueled, reactor to commercial status. Why it matters: While physical plant work is…

Physicists across the globe are on a quest for a particle that makes up nearly 85 percent of all matter in the universe, yet no one has ever directly detected it. Jessica Fry, a fifth-year physics PhD candidate in the Laboratory for Nuclear Science (LNS), is one such hunter.Fry grew up in the San Francisco Bay Area, not far from the SLAC National Accelerator Laboratory. She began dancing at age 3 and by elementary school was competing nationally. On her office desk sits a photograph of her on stage from one of those early recitals, dressed in a ham costume, arms…

A new YouGov poll commissioned by the International Campaign to Abolish Nuclear Weapons (ICAN) shows that a clear majority of people in Sweden support the country joining the UN Treaty on the Prohibition of Nuclear Weapons (TPNW) and oppose the deployment of nuclear weapons on Swedish territory. The nationally representative survey, conducted in May 2026, found that 73% of respondents support Sweden joining the UN nuclear weapons ban treaty, while only 8% oppose membership. The findings also show that 65% oppose Sweden hosting nuclear weapons from another country, despite ongoing discussions about possible nuclear cooperation with France.     Key…

In the last decade, scientists have shown that fusion energy can work, as a physical process. Next question: Can it work economically? A study co-authored by MIT professors Dennis Whyte and Andrew W. Lo proposes a framework for understanding what’s needed to make fusion energy commercially viable in the marketplace. The method considers the physical inputs needed to sustain controlled fusion energy production, as well as the cost of building power plants that can compete in energy markets.“It’s all the things that come along with finding, allocating, and spending money at this scale,” says Whyte, a professor of nuclear science and…

This Hiroshima Day, we are closer than ever to nuclear war Editorial / 5 August 2026, HIROSHIMA DAY commemorates the atomic bombing of the Japanese city by the United States 81 years ago. The atrocity not only killed hundreds of thousands instantly and condemned many more to painful, lingering deaths. It took the world into the atomic age: one in which wars, already hugely more destructive than in previous eras thanks to industrialisation, could plausibly spell the end of human civilisation itself. Three days after Hiroshima the US dropped a second atom bomb on Nagasaki. That remains the last time a nuclear weapon was used in…

Three companies at the forefront of nuclear energy technology have signed a memorandum of understanding (MOU) to evaluate fuel technologies to support advancement of next-generation nuclear power. Curio, which is involved in advanced nuclear materials recycling, on August 6 announced the signing of the MOU with NuScale Power Corp., a developer of small modular reactors (SMRs). Framatome, a France-based industrial company that designs, builds, and services nuclear power reactors, also is part of the agreement. Framatome supplies nuclear fuel, heavy components such as steam generators, and instrumentation systems for the global nuclear energy sector. The companies in a news release…
