  •  Looks to me like the nuclear industry risk (1+ / 0-)

    and process safety analysis wasn't a very good engineering job on the elevated spent pool design at Fukushima (a GE design as I recall), which cause such pools to be subject to blowdown from explosions and their effects on those engineered spent fuel pools.

    The low base elevation of that plant was inextricably part of the cause of being inundated.

    If a tornado takes out power lines to a nuclear plant and the same storm damages the site backup generator or electrical connections to that capability....perhaps is this the ultimate process safety Achilles heal of conventional nuclear plant design?

    •  It certainly was at Fukushima (0+ / 0-)

      You're correct that both the diesel placement and elevated spent fuel pools were bad design flaws.

      In reality, neither the site nor the design would/should have been approved for plants today.  Bear in mind that the plant was 40 years old and the designs were even older.

      TMI, Chernobyl and Fukushima all had very different root causes for their meltdowns.  I've worked on identically-designed plants in similar locations, and the reliability models show different weakest links.  It's likely each plant has its own Achilles heel.  The important thing is to make sure the weakest link is strong enough.

      First they came for the slippery-slope fallacists, and I said nothing. The End.
