Evacuated Canister For Removal Of Molten Radioactive Glass
Technology Category: Design Verification / Prototype Testing
/ Stress and Thermal Analyses

Evacuated Canister System on Melter
Click on graphic for a closer look. |
Description: Pacific Northwest National Laboratory (PNL) has designed
and tested a high temperature evacuated canister for West Valley Nuclear
Services. The function of the evacuated canister is to remove radioactive
molten glass from a hot cell melter cavity during a planned melter shutdown.
The evacuated canister system consists of an L-shaped, 4-inch 304L stainless
steel (SS) schedule 40 pipe, sealed at one end with an aluminum plug and
attached at the other end to a canister. While the canister is being filled,
it is positioned and held above the melter at approximately 15 degrees from
horizontal by two turntable-mounted

cranes. ANSYS finite element analyses were conducted to evaluate the heat
transfer from the glass to the canister and establish a maximum canister
temperature for material strength evaluation. Finite element structural
analyses were conducted to identify areas that required reinforcement for
high temperature use. These results were used to locate strain gauges at
high-stress locations during prototype testing.
