The UCS combines secure storage, transport, and final disposal into a single canister design. Its adaptability makes it suitable for both conventional mined repositories and deep borehole configurations—offering multiple pathways for disposal. Project PUCK specifically confirmed the compatibility of UCS with pebble-format TRISO fuel and highlighted the safety and space-saving advantages of borehole disposal, which minimizes the need for extensive surface infrastructure.
With the nuclear sector under pressure to address long-term waste management, this development adds a scalable option that could work across various reactor types. The technology leverages existing directional drilling techniques, with the capability to isolate waste thousands of meters below the surface in horizontal, slanted, or vertical boreholes.
Beyond the technical milestone, the project also evaluated commercial readiness and cost competitiveness. The economic analysis conducted as part of Project PUCK identified key opportunities to streamline manufacturing and deployment. These refinements could enable broader use of the UCS across the advanced nuclear sector.
The findings suggest Deep Isolation’s approach isn’t just scientifically viable—it’s commercially plausible. This positions the UCS as a strong contender for developers looking to pair reactor innovation with a realistic, long-term waste strategy.
According to Deep Isolation EVP Jesse Sloane, the system goes beyond just containment. When combined with deep borehole technology, it forms a comprehensive back-end solution that could scale with the sector as new reactor designs move toward deployment.
Kairos Power’s leadership echoed that sentiment, calling the project a step forward in demonstrating viable waste pathways for advanced reactors.
