Advanced Drying System to Meet Radiolysis Criteria of Metallic Waste

High dose rate metal waste from core internals, such as BWR channel boxes or control rods are stored in spent fuel pool or site bunker pool. Waste form for final disposal of these high dose rate metal wastes should eliminate water to prevent hydrogen gas generation which can be caused by radiolysis of water. Toshiba’s newly developed drying system for high dose rate metal wastes enable very low content of water even if the waste have a powder layer. Toshiba will provide the total system to fabricate the waste form for high dose rate metal wastes. An operational condition to dry the B4C control rod which is the typical waste with powder layer was estimated based on experimental data.
