Used Nuclear Fuel – Drying the DSC

This is an alternate animation showing the draining of the Dry Shielded Canister (DSC) in a Cask Preparation Area that is outside of the Cooling Pond facility. First, the water is pumped out of the DSC through small port in the inner lid of the canister. That port connects to a drain tube installed in the canister which extends to the very bottom of the canister. The water is pumped back to the Spent Fuel Pool where it originated. After the water is removed, a vacuum pump and filtration system remove all the remaining moisture from the Canister. It is then back filled with helium, an inert gas that prevents corrosion and promotes heat transfer. Finally, an outer lid is installed and welded to the canister and a shielding cover is bolted onto the transfer cask.
