Nuclear Energy

And we should expect more such disasters in the future, experts say.

Containment vessels at nuclear reactors at Fukushima have cracked, confounding the expectations of nuclear engineers. What are the implications?

A partial meltdown has occurred at three nuclear reactors in the Fukushima power plant in Japan, due to a failure of the cooling system.

A partial meltdown has occurred at three nuclear reactors in the Fukushima power plant in Japan. Here's how.

The cooling systems at two nuclear plants in Japan have malfunctioned as a result of a 8.9-magnitude earthquake. A buildup of nuclear decay heat has caused a small radiation leak at one reactor site.

With nuclear energy facilities located near wildfires-prone areas in the US, could a similar situation happen here?

Using a nuclear explosion to plug the gushing oil well in the Gulf might sound like overkill, but Russians suggest it's the way to go.

Physicists may be one step closer to achieving a form of clean energy known as nuclear fusion, which is what happens deep inside the cores of stars.
