Deep Isolation Stands Ready to Support States in Developing a Comprehensive, End-to-end Nuclear Fuel Cycle Strategy

BERKELEY, CA – Deep Isolation Nuclear, Inc. (OTCQB: DBHL) (“Deep Isolation” or the “Company”), a leading innovator in nuclear waste disposal technology, today welcomed the U.S. Department of Energy’s (DOE) announcement advancing the Nuclear Lifecycle Innovation Campus initiative, a new effort to modernize the nation’s nuclear fuel cycle, strengthen domestic energy security and support the continued development of advanced nuclear energy. 

Through the Innovation Campus initiative, DOE is establishing voluntary State-Federal partnerships with states interested in exploring the potential development of regional campuses supporting activities across the nuclear fuel lifecycle, including ultimate disposition of used nuclear fuel.

“The Nuclear Lifecycle Innovation Campus initiative is a game-changing opportunity to secure America’s nuclear energy future,” said Rod Baltzer, President and Chief Executive Officer of Deep Isolation. “As new reactors are deployed and domestic nuclear capabilities expand, it is imperative to also deliver safe, secure and permanent disposal of used nuclear fuel and other radioactive waste – and the Campus initiative rightly establishes that stewardship as the centerpiece of these vital new State-Federal partnerships.”

Deep Isolation stands ready to work with DOE, state governments, local communities, industry partners and other stakeholders as states evaluate the opportunity to host Nuclear Lifecycle Innovation Campuses. The Company’s patented deep borehole disposal technology is particularly well suited to the campus model due to its modularity, scalability and adaptability to a very wide range of geologic settings. It supports disposal of used nuclear fuel from the United States’ legacy fleet of light water reactors, from advanced reactor designs, and also of the highly radioactive residues that remain after recycling of the used nuclear fuel. Disposal capacity can be developed in phases as needed, allowing states to incorporate a permanent waste solution into their broader nuclear development plans from the outset.

Deep Isolation’s technical, regulatory and stakeholder engagement expertise can also help states evaluate their options and integrate responsible waste management and disposal planning into the earliest stages of campus development.

“Communities and states considering a role in the future nuclear fuel cycle should have confidence that the backend can be addressed safely and responsibly,” Baltzer added. “Deep Isolation looks forward to supporting all interested states as they create economic opportunity, strengthen national energy security and ensure that nuclear waste is managed safely for generations to come.”
