Campaign underway to safely store GTCC waste
The system held one canister of GTCC waste from Unit 1, which was retired and partially decommissioned in 1992.
GTCC waste comprises certain materials that have been stored in the spent fuel pools in special containers, such as fuel-related components used for monitoring during operations, fuel assembly inserts and instrumentation wires. There will be one canister of material from each spent fuel pool.
The other material is activated metals that were positioned closest to the nuclear fuel during operation. One such piece is the core barrel, which is being segmented using an underwater cutting technique to be placed in stainless steel canisters.
On Saturday, the first stainless steel canister containing the material from the Unit 2 spent fuel pool was transferred to the dry fuel storage pad and loaded into the TN-NUHOMS storage system. Additional modules had previously been added to the system to accommodate the GTCC canisters.
Safety will be the top priority as the team works through the process of storing all 12 canisters. Some of the team members have deep experience with the process of loading and storing the NUHOMS canisters, having worked on the initial spent fuel loading campaigns for the system.
The team is using lessons-learned from those previous campaigns as well as the Holtec campaign that was completed in August 2020.
"We have a strong level of experience with this crew and good supervisory oversight through every step of the process," said Jerry Stephenson, ISFSI (Independent Spent Fuel Storage Installation) engineering manager.
The GTCC campaign is expected to be completed in 2023.
