French startup Stellaria is asking regulators for permission to build an experimental fast-neutron molten salt reactor that ...

Experts want the responsibility for permanent disposal of nuclear waste in the hands of a nonprofit or similar corporate entity. Which is a nice way of saying the ...

WASHINGTON, Aug. 18, 2025 — From electric cars to artificial intelligence (AI) data centers, the technologies people use every day require a growing need for electricity. In theory, nuclear fusion — a ...

Fireplaces are cozy until it’s time to shovel out the ashes. Nuclear power has the same problem: abundant, reliable energy paired with a growing pile of difficult-to-discard spent fuel. But a new ...

The rewrite was done to speed up the construction of a new generation of nuclear reactors. Critics warn it could compromise safety and public trust.

For decades, the world has grappled with how to safely and permanently dispose of vast amounts of highly radioactive waste from fission reactors. Now, a bold solution has emerged that could turn this ...

The waste could be used for nuclear fusion, say researchers. Although nuclear fission, which powers nuclear reactors, can provide plenty of energy, it also produces potentially dangerous radioactive ...

Stellaria, a French startup born out of the CEA and Schneider Electric, has raised €23 million (approximately $26.88 million USD) to build a new kind of nuclear reactor, one that can actually get rid ...

Uzbekistan's Atomic Energy Agency and Russia's TVEL have signed a memorandum of understanding relating to the development of ...

Small nuclear reactors are pitched as cheaper, safer, faster and easier to finance than their conventional counterparts. Hype around them is building fast, but some experts warn it ignores fundamental ...
