Re: dave's answer to one of your questions
The RTM does not address probabilities of event occurrence, it addresses
the radiological consequences should the event occur.
>From page D-5:
Purpose: To estimate offsite consequences based on the status and age of
the fuel in the spent fuel pool and on release pathway conditions.
Discussion: This method uses event trees containing precalculated dose
estimates to determine the offsite consequences of a release from damaged
fuel in a spent fuel pool. This method is designed to provide a best
estimate of the dose when the source term is not known...

Again, this is hardly any secret. This scenario is analyzed in the NRC's
Response Technical Manual (RTM-96, Vol. 1, Rev 4; March 1996). Section D of
this document is Spent fuel Pool Damage and Consequence Assessment. One of
the accidents analyzed is a Zircaloy cladding fire...
You didn't give the probability of all of those things happening at once.
Seems to be a real rare event. Really unlikely to occur. To asses this
kind of scenario, the probability of occurance must be given.
