IN Mr Renfield's letter 'Nuclear Power' (April 27), I think he claims that it currently costs £200 million/year to store all our nuclear waste, and by 2032 will cost £40 million a year at most from then on.

If Mr Renfield was able to find an official nuclear energy spokesperson who would repeat this claim, I would send this costing to energy correspondents and ask if these costings are likely to be true.

If they said 'yes', that's what nuclear waste disposal really costs, no hidden extras, I would invest as much money as I could scrape together to buy nuclear power shares, that's brilliant!

But I believe Mr Renfield has been talking to the kind of nuclear scientist who gets decimal places mixed up when using big numbers. If so, I'll invest in the St Briavels wind turbine if the shares haven't sold out already by then.
