Re: Fast Neutron reactor
These costs are caused by the utterly barmy regulations around nuclear (which seem to have been deliberately designed to poison the industry and stunt its growth), and the parasite industries that have grown out of those regulations.
The real problem with radioactivity is that it is so detectable in tiny amounts, and scary because people think it causes cancer, when really it's not going to cause harm at all in small amounts. Even pretty large amounts such as the dose received by the Fukushima 50, nuclear bomb testing engineers etc. have not caused anywhere near as much harm as we all expected. Why? Because life on earth has evolved to cope with quite a lot of ionising radiation in the background. The radiation was there before life was. Whereas we have NOT evolved to deal with microplastics, nanoparticulate carbon (which ironically exist in modern ULEZ-compliant diesel exhausts but not the old ones..) etc. etc.
The regulations at Sellafield are so ridiculous that they are measuring single Bequerels outside casks and saying that's too high. Literally if you can detect a single photon of gamma, it can't be shipped out. This I heard from someone who works in safety at the place.
I knew a project manager from that place too.. He said that the workers there would all conspire to make sure any new project manager would fail at his or her job, and would just get so frustrated that they eventually either quit or let the guys do whatever they want.
That is why decommissioning is so expensive. It's not just nuclear regs, it's UK Health&Safety legislation too, and in terms of cost the two are multiplicative.
But without bloody revolution, societal poison just never goes away. So I agree, the age of nuclear is over. Until someone drops a bomb on our heads and suddenly sellafield is the least radioactive place in Britain
