Unlike Nuclear fusion which has never had net generation of power, molten salt nuclear fission power had 2.5 megawatts of net power generation from a US nuclear prototype back in the 1960s. The US government had major work on molten salt nuclear reactors form the 1950s through the 1970s.
There is now a multi-billion race from many US companies and China and Canada and European countries to develop molten salt nuclear power.
* Molten salt reactors can produce one thousand times lower volume of radioactive waste of existing nuclear reactors because of deep burn. More complete conversion of the nuclear fuel. The unburned uranium and plutonium can be used and what is left would be products with half-lives of 100 years or less.
* Molten salt reactors can have designs that are proof against nuclear meltdowns
* The chinese reactors could use thorium. China has some of the world’s largest reserves of the thorium metal.
