  •  Not a clone. It's not a GE boiling water reactor.. (15+ / 0-)

    ...with a problematic container vessel design and valve problems. (Which doesn't mean it's safe, of course.)  It's a pressurized water reactor built by Combustion Engineering, a very different design.

    Don't tell me what you believe. Tell me what you do and I'll tell you what you believe.

    •  True, but Cooper plant (3+ / 0-)

      just downstream, on the same river, in the same low floodplain IS a GE BWR. and it's old (1974). Cooper Nuclear Station

      •  Yes but it's a different version of (0+ / 0-)

        the GE BWR in Japans. The US plants did various upgrades after buko complaints on design. The Japanese rejected this do this so Mark I containment, for example in Fukushima Diani is has only had small upgrades. Fukushima Diachi on the other hand (the one near the one that had the accident but didn't have an accident) is a Mark II. We don't know if this is what made a difference in any event (unlikely) but siting probably did as the plant is angled somewhat differently...it too was totally flooded but had no accident.

        PWRs are of course different birds altogether but I don't believe older ones are necessarily that much safer for other reasons.

        Most spend fuel ... the majority of the hundred or so tons of spent fuel from an older reactor are not part of the 'temporary' spent fuel load that we saw with the BWR. They are usually ground level and decay heat is all but gone.
