Thorium cannot in itself power a reactor; unlike natural uranium, it does not contain enough fissile material to initiate a nuclear chain reaction. As a result it must first be bombarded with neutrons to produce the highly radioactive isotope uranium-233 – 'so these are really U-233 reactors,' says Karamoskos.
Are there any working thorium reactors?
Aqueous Homogeneous Reactors (AHRs) have been proposed as a fluid fueled design that could accept naturally occurring uranium and thorium suspended in a heavy water solution. AHRs have been built and according to the IAEA reactor database, 7 are currently in operation as research reactors.
Is anyone building a thorium reactor?
A team from the Nuclear Research and Consultancy Group (NRG) the Netherlands has built the first molten salt reactor powered by thorium in decades. There are several basic facts of nuclear power that have made it a tough sell around the world. For one, the uranium needed for nuclear power plants is rare and expensive.
