Deep Isolation has completed a groundbreaking three-year project, resulting in the creation of a revolutionary Universal Canister System for managing used nuclear fuel and high-level radioactive waste from advanced reactors. This innovative system, known as Project UPWARDS, has passed rigorous physical testing and validation, ensuring its readiness for disposal. The project's name, Universal Performance Criteria and Canister for Advanced Reactor Waste Form Acceptance in Borehole and Mined Repositories Considering Design Safety, reflects its comprehensive approach to waste management.
The project involved a collaborative effort between Deep Isolation, the University of California, Berkeley, Lawrence Berkeley National Laboratory, and NAC International. Together, they developed waste form acceptance criteria and conducted integrated safety and performance assessments for various repository types. The US Department of Energy's ARPA-E initiative provided crucial grant funding for this ambitious endeavor.
A key milestone was the fabrication of the first prototype canister in partnership with R-V Industries, Inc. in Pennsylvania. Subsequent testing at the Deep Borehole Demonstration Center in Texas demonstrated the canister's mechanical integrity and operational reliability under simulated real-world geologic conditions, offering an unprecedented level of physical validation for nuclear waste disposal systems.
The Universal Canister System is designed with versatility in mind, accommodating a wide range of advanced reactor waste streams, including vitrified waste from reprocessing, TRISO spent fuel, and halide salts from molten salt reactors. Its compatibility with modern dry storage and transport infrastructure, coupled with its ability to meet performance and safety requirements for both borehole and mined repository options, provides significant flexibility and reduces uncertainty in future waste disposition.
Deep Isolation's project has yielded a robust technical foundation, poised to support regulatory engagement, pilot deployment, and commercialization efforts. Jesse Sloane, Executive Vice President of Engineering at Deep Isolation, expressed enthusiasm for the universal, triple-purpose canister's extensive testing, emphasizing its potential for real-world deployment.
Looking ahead, Deep Isolation and NAC International are eager to integrate this cutting-edge innovation into their existing licensed systems for spent nuclear fuel storage and transportation. This collaboration aims to commercialize the Universal Canister System globally, marking a significant step forward in the safe and efficient management of nuclear waste.
