  1. High level nuclear waste has a 30,000 year half life because the long life actinides have not been used up. PWR creates them cannot burn them. Just 4% of the energy is extracted. Fast spectrum molten salt reactors by Moltex and Elysium will be fuelled by nuclear waste. Fully using the energy drops the waste 1/2 life from 30,000 years to just 30 years.

  2. Moltex are going through homologation in Canada for a fast spectrum molten salt reactor. There is no fancy molten metal coolant and there is no fuel reprocessing. They take used fuel and chemically process it into a salt which is diluted with chloride salt. The isotope content is unchanged. The salt fuel is packed into open ended stainless tubes. The reactor core uses the same salt (minus fuel) as a heat transfer medium. The reactor itself is a concrete box with a third salt loop to remove heat. It’s fully self regulating, cannot overheat and has one moving part - a salt stirrer to keep the regulatory body happy. It also has power cut-off rods but really doesn’t need them. It’s intrinsically safe.
