Scientists have built the first-ever thorium reactor. Thorium is both more easily accessible and less dangerous than uranium—the most common fission fuel. The system also uses molten salt ...

Thorium is highly efficient, with a single ton producing energy equivalent to 200 tons of uranium or 3.5 million tons of coal, supporting sustainability and reduced greenhouse gas emissions.

Europe has been turning uranium into energy for over half a century. In the process, the continent has amassed vast stockpiles of nuclear waste. This radioactive material can take millions of ...
