Description
The reference spent fuel canister would contain four PWR or nine BWR fuel elements, which would be placed in channels in a cast steel canister or canister insert. A residual void volume remains, because of the clearance required for placement of the fuel elements into the canister. This volume may become water filled following canister breaching, and provides a reservoir in which radionuclides released from the fuel are dissolved or precipitated. The volume of water is considered in criticality calculations.
