Radiation dose rates from consolidated fuel in current generation shipping casks
As part of a DOE study of public risk from cask transport of consolidated and unconsolidated spent fuel cooled beyond five years, radiation dose rates from two current generation shipping casks were evaluated. The IF300 rail shipping cask (with a capacity of seven PWR assemblies) and NLI 1/2 truck shipping cask (with a capacity of one PWR assembly) were selected as appropriate cask models. A Westinghouse 17 x 17 fuel assembly with a 3.3 wt % /sup 235/U enrichment, operated at a specific power of 37.5 MW/MTU for 880 full-power days (20% downtime in history), and discharged at a burnup of 33 GWD/MTU was specified. Results for spent fuel cooling times of 5, 10, 15, and 25 years are reported here.
