Problem

Special canister required for waste removal project was difficult to maneuver into place.

Solution

The added length of the tipstick hanging from the overhead crane allowed the waste container to be placed in the shipping container.

Description

A nuclear research facility is in the process of demolition and deactivation of buildings. The building was used as a spent-fuel metallurgical test facility. Some of the waste from that process were to be removed from the building to allow demolition and deactivation activities to continue. The high-level waste dose rates and concentrations required removal from the building in a special shipping canister. The truck that hauled this canister could not back into the building far enough for the overhead crane to reach the canister. Barnhart solved the problem by hanging the tipstick from the overhead crane. The added length of the tipstick provided enough distance to allow the waste container to be placed inside the shipping canister. The process involved disassembling the canister, installing the inner waste container, and reassembling the shipping canister. Two canisters were loaded. The waste was then shipped out to the repository onsite for long-term storage.
