A “nuclear engine” has many advantages, notably providing a vehicle with an almost unlimited supply of onboard power, with no need for regular refuelling. That’s particularly attractive for large ships and submarines, where fuel stops at sea are few and far between. It’s even better for space craft, which cannot refuel at all.

The U.S. Nuclear Regulatory Commission has issued its first construction permit for a commercial nuclear reactor in eight years.

Oak Ridge National Laboratory (ORNL) reports it has tested a high-temperature fission chamber prototype built by Curtiss-Wright Nuclear that operated steadily at 800 degrees Celsius (about 1,472 degrees Fahrenheit) during a weeklong irradiation test at The Ohio State University Research Reactor.

We got neutrons, yeah!” The shout came after years of after-school effort inside a Dallas home, where a seventh grader had been quietly assembling a machine most people only encounter in advanced

That was the thought racing through physicist Francis Perrin’s mind in May 1972. He was examining a dark piece of uranium ore at a nuclear fuel processing plant in southern France. The uranium sample, extracted from a mine in Gabon, Africa, held a secret ...

A global nuclear energy resurgence is underway, driven by the need for a stable, low-carbon energy mix and massive electricity demand projections spurred by the artificial intelligence boom. Deep Fission, a U.S. company, has developed a "gravity reactor ...
