Deep Isolation is a Berkeley, California-based company focused on the long-term disposal of spent nuclear fuel from commercial reactors. It pursues a horizontal borehole approach that places waste beneath a thick, geologically stable and impermeable rock formation, leveraging established drilling methods in a novel disposal application. The goal is to provide a safe, potentially lower-cost option for permanently isolating spent nuclear fuel, addressing a core challenge in nuclear waste management. Its target market comprises operators of commercial nuclear reactors seeking a permanent disposal solution for spent fuel within the utilities sector. In April 2026, the company announced the launch of a full-scale Universal Canister System prototype to be displayed at the ARPA-E Energy Innovation Summit.
