Antinuclear

For all its cockiness, the nuclear industry is deeply nervous about the future

Nuclear industry faces up to reality of ‘interesting times’ The Engineer, 7 December 2012 | By Stuart Nathan  “………Part of the problem is that the nuclear landscape is so complicated, especially in the UK, with its history as a nuclear
pioneer and the legagcy of experiment that has left behind. John Clarke of the Nuclear Decommissioning Authority, again reflecting the mood of realism, put it in a way which pretty much everyone would understand. ‘It’s like telling children to put their toys away before getting out new ones. Clearing up the mess is a key enabler to new build.’

…… .it’s relatively easy to put toys away. Nuclear is different. ‘At Sellafield, we’re dealing with structures which were put up in the 1940s in great haste to support military programmes, where the only concern was “is it safe for today”,’ he said. ‘They were neverdesigned to have waste taken out of them, and the waste is poorly categorised — we often don’t really know what it is.’

The situation isn’t much better even at industrial-scale power stations, said Peter Walkden, commercial director of Magnox. ‘It was never going to be easy to decommission a 50 year old plant that was never designed to be decommissioned, under a regime that was designed for operation,’ he said. Decommissioning a Magnox plant takes the best part of a century — three years to defuel, then ten years of preparation for care and maintenance while radioactivity subsides (the stage that current decommissioning projects are in), followed by 85 years of care and maintenance, then about ten years to clear the site.

A bit more than just putting the toys away, and something that can’t be done before building new plants’. ….”
