Llewellyn King - One of the glories of nuclear technology is also one of its frustrations: You can design a reactor in a hundred ways. It is like the French cheese dilemma; because there are some 500 cheeses in France, who is to say which are the best?
Llewellyn King - The great event of the nuclear calendar for 2011 was the earthquake and tsunami that hammered three reactors at the Fukushima Daiichi plant in Japan
If you are a nuclear power believer, these sturdy old machines proved their mettle. They withstood all that nature could throw at them, although terrible damage resulted from the loss of external power and the swamping of the emergency diesel generators.
The extraordinary thing about Fukushima is that although more than 15,000 Japanese died as the result of the earthquake and tsunami, no one died directly from the nuclear accident or from the release of radioactivity.
