> Thorium molten fluoride
Most of the establishment nuclear science people want nothing to do with this.
WIKI Research and development of thorium-based nuclear reactors, primarily the Liquid fluoride thorium reactor (LFTR), MSR design, has been or is now being done in the United States, United Kingdom, Germany, Brazil, India, China, France, the Czech Republic, Japan, Russia, Canada, Israel, Denmark and the Netherlands.[15][17] Conferences with experts from as many as 32 countries are held, including one by the European Organization for Nuclear Research (CERN) in 2013, which focuses on thorium as an alternative nuclear technology without requiring production of nuclear waste.
The neurotics are very good with Thorium but Thorium reactors produce copious quantities of Tritium which is a REAL PROBLEM that nobody has yet solved.
The proposed reactor is a pebble bed gas cooled super complicated.
The only way to go is with a Molted Salt Reactor (fuel dissolved on the salt) along the design put forth by www.terrestrialenergy. They are doing things right. https://www.terrestrialenergy.com/category/press-release/

Of course they don’t. All you get from a LFTR is power. With a fission plant, you put in Uranium, you get Plutonium. The power is just a pretense.
