Ted -
I don't know your definition of "tolerable" (maybe you're talking about
NRC's siting rules) but given current federal emergency response guidance, a
responsible state radiological official would be hard pressed NOT to recommend
that individuals in the vicinity of a ruptured spent fuel cask be evacuated (or
at a minimum, sheltered in place) given your estimate of a 1 rem dose, unless
there were "extenuating circumstances" such as an ice storm, a hurricane, etc.
which would make evacuation more hazardous in and by itself.

As to what can be released from a ruptured shipping cask, I thought we agreed on the last go-around that the noble gases are not a serious health hazard and that we should not assume that all non-volatile activity is in highly respirable form. In this case, I recall that the total dose to the most exposed person was about 1 rem. Do I remember that wrong? If it's less than 25 rem, then it's still a tolerable emergency dose under today's rules, is it not? And we should not predict any deaths in that situation.That's all we intended by our statement. |
