  1. Today’s fast spectrum reactors using salt as heat transfer fluid remove almost every hazard associated with traditional pressurised water reactors. No pressure, no water = no possible steam explosion. No water so no steam bubbles = zero risk of local overheating within the core No water so steam can’t react with zirconium creating hydrogen and oxygen No water so neutrons cannot split water into hydrogen and oxygen No free hydrogen and oxygen within the core so reformers are not needed. No free hydrogen and oxygen to degrade the steel pressure vessel and cooling systems. Fuel rods are vented so no risk of gaseous fission products causing over-pressure in the fuel. The most biologically dangerous elements (caesium 131 and iodine 137) form caesium iodide within the fuel which is not a gas. Molten chloride salts with no oxygen present are less corrosive than very hot pressurised water. The nuclear reaction is self controlling. Too much temperature slows the fission rate too little speeds it up. Remove the cooling circuit and the react cannot overheat. The core has one moving part - a stirrer to ensure the salt is kept in circulation. Why are we not building these things as quickly as possible? Or at least a test plant. The resin work is done years ago. The delays are entirely regulatory.

  2. KGB used German Greens to trash nuclear power as that made a bigger market for Russian gas and oil.

  3. We could have nuclear power which burns existing nuke waste at costs cheaper than gas fired plant. All we need is a safety regime focussed delivery instead of (alleged) safety being used to prevent delivery
