Making the rounds: Japanese nuclear power plant accident kills 4. IANAPPW (I am not a power plant worker), but it sounds as if the leak ocurred in the secondary circuit, which by definition is not radioactive. Stilll, getting parboiled is definitely pretty far down on my list of "desirable ways to die". Ouch.
Of course, Reuters, being (as I understand it) UK based, couldn't resist a pot shot at nukes in general:
The incident [...] is certain to increase public distrust of the nuclear industry in Japan, which depends on nuclear power for a third of its energy needs.
