Molten Salt Reactor FAQ - Ensuring Nuclear Performance

A thorium reactor is simply any nuclear reactor that uses thorium as its fuel. Most reactors running today are optimized for uranium, not thorium. This means that they are not as efficient as they can be in extracting energy from thorium. The most promising ways to use thorium are by building a Molten Salt Reactor (see questions 2 and 3) or ...
