  •  This kind of accident makes me wonder about all of (8+ / 0-)

    the possible failure modes and regulatory and engineering issues raised by something like this.   For example, it makes me wonder about all of the following from a safety assurrances standpoint.....

    1.  Methods of both automatic and manual operations and fault tolerance in electrical power supply systems inside the plant.

    2.  Methods of lockout, lockin and isolation of emergency generator equipment circuits from outside power sources.

    3.   Physical vulnerability of backup power generator buildings and structures and wiring between the gnerators and the plant buss for internal plant power, including vuinerability to floods and physical attack...

    •  You're absolutely right (12+ / 0-)

      to be concerned. Single-point failures that trigger cascades is another. That has happened more than once - and entirely OFF the projection scenarios - still waiting to be addressed. NRC asks the permission of the industry these days, it doesn't actually ORDER any new retrofit requirements. Honest.

      And that is entirely, completely, ultimately unacceptable. Which is why they don't let us know much about what's going on.

      •  And then there is other management and risk (2+ / 0-)

        issues like......whether emergency generator systems (including fuel tanks) ought to be hardened against physical attack using military methods as a required risk reduction method through enactment of an NRC rule requirement ......since that vulnerability together with offsite power connection capability vulnerability might be the weakest link in nuclear plant security.
