Dispersal of Spent Fuel -Reply
It will make a big difference if the fuel element has been in a reactor and contains
The question is very difficult to answer generically, but to start scoping it out, I
would start with the release fractions in Table 13 of NUREG-1140, "A Regulatory
Analysis on Emergency Preparedness for Fuel Cycle and Other Radioactive
Material Licensees." That table gives release fractions of 0.001 for uranium, 0.01
for Cs-137, and 0.5 for iodine 131, for example. That is the fraction of the material
that might become airborne as respirable particles in an accident.
I can send you a copy of the document if you want it.

I'm afraid I was too discrete in my original query. Specifically, what would happen if
an explosive charge was set off under a spent fuel element? The scenario is
outdoors in an unconfined geometry.
How would you assess the risk to the community?
