McKay only has a short passage for decommissioning:
Economics of cleanup
What’s the cost of cleaning up nuclear power sites? The nuclear decommissioning
authority has an annual budget of £2 billion for the next 25
years. The nuclear industry sold everyone in the UK 4 kWh/d for about
25 years, so the nuclear decommissioning authority’s cost is 2.3 p/kWh.
That’s a hefty subsidy – though not, it must be said, as hefty as the subsidy
currently given to offshore wind (7 p/kWh).
That’s what the government sets aside, £2 billion (is that American billion or British billion, that’s a 1000-fold difference. McKay is British…), isn’t the actual cost. Cost will come in later years and payed up by the public.
Two chapters later he discusses how small the dangerous waste is. Well, that waste gets buried somewhere, but not safely. It gets in the water system again, like with Asse II.
But all in all an interesting read.
