Over at the Telegraph, Ambrose Evans-Pritchard is extolling the virtues of molten salt nuclear reactors, suggesting that these represent the future and could be cheaper and safer than the pressurised water reactors that are currently in vogue.
The Alvin Weinberg Foundation in London is tracking seven proposals across the world for molten salt reactors (MSRs) rather than relying on solid uranium fuel. Unlike conventional reactors, these operate at atmospheric pressure. They do not need vast reinforced domes. There is no risk of blowing off the top.
The reactors are more efficient. They burn up 30 times as much of the nuclear fuel and can run off spent fuel. The molten salt is inert so that even if there is a leak, it cools and solidifies. The fission process stops automatically in an accident. There can be no chain-reaction, and therefore no possible disaster along the lines of Chernobyl or Fukushima. That at least is the claim.
It's an idea, anyway.
