Sizewell C: the Unanswered Questions June 8, 2026 Alison Downes, 8 June 2026: On the day the Public Accounts Committee begins scrutiny of Sizewell C, [1] and almost a year to the day that the government’s announcement of its £14.2bn investment paved the way for a Final Investment Decision, Stop Sizewell C is publishing a report “Sizewell C – The Unanswered Questions”. This highlights what is known, what it is impossible to know, and what the government continues to keep secret about Sizewell C. It is a story of secrecy, obfuscation and deception and contains a number of recommendations. [2] Read here:  Sizewell C, the Unanswered Questions,…

A Colorado-based fusion energy company said the U.S. Dept. of Energy (DOE) has approved the company’s preconceptual technical design for its commercial fusion power plant. Xcimer Energy on June 10 said the DOE also supports the group’s development roadmap for Athena, which is the reference architecture for what the Denver-headquartered company said would be its fleet of fusion power plants. Xcimer is among several U.S. and global groups working to commercialize fusion energy. Xcimer called the DOE approval a milestone for its efforts, and in a news release wrote that it “positions Xcimer among the front-runners to commercialize fusion energy…

David Stevenson, who led a national campaign against offshore wind power for the Delaware-based Caesar Rodney Institute, is now fighting land-based solar and wind farms and promoting fossil fuels and nuclear power with the Michigan-based Mackinac Center for Public Policy, a group funded by the donor network of petrochemical billionaires Charles and Chase Koch.   The Caesar Rodney Institute (CRI) and Mackinac Center are both affiliated with the State Policy Network (SPN), which serves as the central hub of a 50-state network of right-leaning think tanks. SPN has long sought to derail state clean energy and climate change policies, and is…

The rise of artificial intelligence is riding on the back of an enormous data center expansion. Data centers are projected to account for anywhere from 9 to 17 percent of total electricity usage in the U.S. by the end of the decade. Today, around a third of data center electricity is devoted to cooling the chips that run AI models.That’s the process Ferveret is working to make more efficient. The startup, founded by Reza Azizian, a former MIT postdoc in nuclear engineering, and Matteo Bucci, MIT’s Esther and Harold E. Edgerton Associate Professor in the Department of Nuclear Science and…

According to new research released today by ICAN, in 2025, the nine nuclear-armed states spent $16.8 billion (19%) more on their nuclear arsenals than the year before, a total of $119 billion, or $3,768 per second on nuclear weapons. The United States had the biggest increase from 2024- 2025, at $12.4 billion, and spent more than all of the other nuclear-armed states combined, at $69.2 billion. China remained second, at $13.5 billion, and the United Kingdom came in third, spending $12.6 billion. Across the board, nuclear-armed states are making plans to retain their arsenals for decades to come.…

Expert Warns of ‘Rubber Stamp’ Approvals as Ontario Expands Nuclear Spending the changes effectively shift final authority from the Canadian Nuclear Safety Commission (CNSC) to cabinet if concerns arise during assessment. It also shifts accountability if those decisions eventually go wrong—although the elected officials involved would likely be out of office by the time the full impacts were known. the budget “goes on at some length about how wonderful [nuclear projects] are in terms of their economic contributions, but never actually talks about costs.” the combination of the proposed new builds, the SMR pilots, and refurbishments will push capital expenditures “north of $400…

Antares Nuclear Inc.’s Mark-0—a sodium heat-pipe-cooled microreactor fueled by high-assay low-enriched uranium (HALEU) tri-structural isotropic (TRISO) fuel compacts—has achieved zero-power criticality at Idaho National Laboratory’s (INL’s) Reactor and Critical Experiment (RACE) facility, becoming the first advanced reactor to reach that milestone under the Department of Energy’s (DOE’s) Reactor Pilot Program. The development, announced on June 4, also marks the 53rd reactor built at the INL site since 1951 and the first novel reactor design to achieve criticality at the laboratory in more than 50 years, according to INL Laboratory Director John Wagner. The much-watched DOE Reactor Pilot Program, established under President…
