I added an erratum to the book trying to improve the accuracy of my discussion of the cost of nuclear decommissioning: my error was that I attributed the nuclear decomm. cost to civilian electricity generation, but in fact the lion's share of the clean-up cost is for military mess. C.Duro then posted a comment disputing this fact and accusing me of dishonest presentation. I stand by the fact: I got this same erratum twice from two independent sources, then checked it, and I don't think that the Telegraph article cited by C.Duro disproves the erratum. The lion's share (ie more than half) of the cost is for military clean-up.
