Unsure about nuclear power? Here's the five questions ...
... you must answer to decide
Twenty five years on from Chernobyl, the heated debate on nuclear power remains resistant to cold facts: simply too few are known. But making your own judgements on five key questions will lead to your answer
Containing the elemental forces that rage inside a nuclear reactor is one of the great achievements of science, but losing control, as happened 25 years ago on Tuesday at Chernobyl, is one of its greatest failures.
So what to think of nuclear power? People often ask me if I support or oppose the building of new nuclear power stations, presuming I think that because of my job, I'll know the answer. If only it was that easy.
Until the disaster at the Fukushima nuclear plant, I would say I was 51% in favour, on the basis that we need all the low-carbon electricity we can get to avoid the worst impacts of climate change and that I tend to trust scientists having been one.
But 51% in favour is a pretty unsatisfactory position - it's 1% off I don't know. Surely I can be more certain than that, I thought.
