Portable Shielded Containers TRIZ Cases
- Portable Robotic Welder for Hermetic Nuclear Waste Canister Sealing
A portable robotic arm welds nuclear waste canister lids with joint tracking to cut worker radiation exposure while maintaining hermetic seal quality.
- pH-Control Backfill Capsules for Radioactive Waste Container Corrosion Delay
Water-soluble pH control capsules release alkali in rainwater to keep vault backfill above pH 8.5 and delay disposal container corrosion.
- Shielded Multi-Vial Radioisotope Container With Pressure-Balancing Vents
A compact shielded container uses separate source and transfer vials, balancing vents, and a fluid trap to track radioisotopes while limiting leakage.
- Linked Waste Capsules With J-Slot Retrieval for Deep Wellbores
Pin-and-J-slot capsule links enable single-trip waste emplacement and retrieval in deep wellbores, cutting handling time and exposure.
- Hazardous Waste Canister Pressure Balancing Under Underground Load
Pressure-balancing material fills canister voids to counter underground fluid pressure and prevent hazardous waste container collapse.
- Radioactive Waste Shielding Module With Impact Damping and Heat Venting
Elastic metal centering elements and convection windows protect radioactive waste containers from impacts while improving heat release and shielding.
- Drillhole Waste Canister Sealing and Shielding for Nuclear Storage
Deep drillhole storage uses integrated shielding, support, and sealing to contain nuclear waste while managing heat and handling loads.
- Drillhole Waste Canister Retrieval With Corrosion-Resistant Latching
Corrosion-resistant canisters, sacrificial anodes, and robust latching enable reliable hazardous waste retrieval from deep drillholes after long storage.
- Radioactive Material Transport Cask Seal Protection Under Fire Impact
A thermal shield protects the lid seal during fire exposure while impact limiters absorb kinetic energy to prevent cask damage.
