This marks the first time anyone has successfully reloaded fuel in an operational thorium molten salt reactor (MSR) without ...

More than 440 commercial reactors generate almost 10 percent of global electricity, a carbon‑free flow that has quietly been ...

At 1:23 AM on April 26, 1986, an uncontrolled reaction triggered a series of massive explosions that blew the 1,200 ton teactor lid off, exposing Chernobyl’s radioactive core. The effects ... The mass ...

Chernobyl, Three Mile Island ... These included trying to get the molten fuel cartridges (which held the uranium rods) out of the core and into the cooling pond by having men in radiation suits push ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the ...

Mars' magnetic mystery may finally have a solution—scientists now think the Red Planet’s ancient magnetic field only existed ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously ...

Until now, most studies of early Mars had relied on magnetic field models that gave the red planet an Earth-like inner core that's solid and surrounded by molten iron. The researchers were ...

But war was a scenario its engineers never envisioned. A Ukrainian air defense unit illuminating a hole in the steel shield at the Chernobyl nuclear power plant last month. The fire started by the ...
