West Valley Support Program evacuated canister system design

Pacific Northwest Laboratory has prepared a preliminary design of the evacuated canister system for the West Valley Demonstration Project (WVDP). The function of the evacuated canister is to remove molten radioactive glass from the WVDP melter cavity during a planned melter shutdown. The proposed evacuated canister system consists of an L-shaped, 4-in.-diam Type 304L stainless steel schedule-40 pipe sealed with an aluminum plug at one end and attached to a canister at the other. While it is lifted, the canister is positioned and held above the melter by two cranes at [approximately] 15 deg from horizontal.
