This problem in Japan has if anything made me more keen on nuclear power. Why? Well, partly because it has prompted me to take a look at the latest reactor designs. Travelling Wave Reactors caught my interest after Bill Gates’s TED talk, however there are problems – they will only be ready in around 20 years, plus they don’t breed any fuel for the future. There’s another design, Integral Fast Reactors which also look interesting, and are here today.
