Not Three Mile Island but Chalk River in Canada; a fascinating historical note from the Economist:

Three weeks after Japan’s earthquake and tsunami crippled the Fukushima nuclear power plant, spewing radiation as far as Iceland, clean-up crews have been working around the clock to bring the reactor under control and contain the leakage. Their life is a nightmare…

The fear and danger is beyond comprehension for most people, and in particular the political leaders who must order men in to danger. But interestingly, it is not unfamiliar to former American president Jimmy Carter. Nearly half a century ago, as a young naval officer, he led a 23-man team to dismantle a reactor that, like Fukushima, had partially melted down…

“The radiation intensity meant that each person could spend only about ninety seconds at the hot core location,” wrote Mr Carter in “Why Not the Best?”, an autobiography published in 1975 when he was campaigning for the presidency.

I may try and get hold of that book. I see it’s going for $0.01 second-hand.
