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…

The costs of nuclear wastes from “in service” nuclear submarines. Richard Marles weasels his way out of this problem 3 June 2026 Noel Wauchope AIM Extra ,  It is a rather nauseating entertainment, watching Australia’s Defence Minister Richard Marles wriggling around to con the public into believing that it will be cheaper for Australia to buy used nuclear submarines, than to buy new ones. I’m not quite sure who invented the new term to replace “used” – but “in service:” is a lovely euphemism, worthy of Marles. Australia’s not buying “used” nuclear submarines – oh no – we’re getting “in service” nuclear…

Hydrogen was the future once. But while the UK was quick off the mark in investigating the potential of H2 for heating homes, much of the original plans have been abandoned in favour of solar, wind and electrification, writes Ros Taylor. Credits Scharfsinn | Shutterstock, all rights reserved. Methane gas heats more than three-quarters of British homes, making it one of the main sources of CO2 emissions. In 2017 the UK launched a programme called Hy4Heat to investigate whether it was feasible to move British households over from methane gas to hydrogen. There would be trials of home hydrogen boilers,…

Another U.S.-based energy company said its technology has achieved key performance metrics that advance its goal of commercial fusion by the mid 2030s. California-headquartered Pacific Fusion on June 2 said its core pulsed power technology is on track to achieve net facility gain by 2030. That’s the state where the “entire fusion machine produces more fusion energy than the energy initially stored in the system used to run it,” according to Keith LeChien, co-founder and CTO of Pacific Fusion. The company, founded in 2023, said it has raised more than $1 billion in funding led by Massachusetts-based venture capital firm…
