Deep Isolation has performed two field tests to show that retrieval of nuclear waste packages from a deep borehole is possible using off-the-shelf oil and gas exploration tools. Together, this data and field test results present compelling evidence that retrievability from boreholes can be assured if retrievability is desired for a given period of time.

2024 ANS Annual Conference

Several of our team members will be in attendance during the ANS Annual Conference, one of the largest gatherings of nuclear professionals in the country where the brightest minds engage – and inspire – leaders from across the nuclear science and technology landscape.

Event, June 3-5, 2024 in Louisville, KY

18th Annual RadWaste Summit

COO Rod Baltzer is invited as a speaker to the Annual RadWaste Summit, a renowned forum to discuss challenges and solutions to the management and disposition of radioactive waste. This forum is also a powerful relationship-building opportunities to reach some of the most influential government officials and organizations.

COO Rod Baltzer is speaking on a panel discussing nuclear waste issues at the Energy Communities Alliance’s third New Nuclear Forum, the only meeting bringing together DOE, federal, state, local and tribal governments and policymakers with developers, utilities, regulators, industry, and academia to identify opportunities, challenges and to build the partnerships necessary to support new nuclear development.

Event, April 23 - 25, 2024 in Dallas, TX

EarthX E-Capital Summit Innovators

COO Rod Baltzer is invited to present at the 2024 EarthX E-Capital Summit. The EarthX annual E-Capital Summit, part of the EarthX week, is an invitation-only conference that has convened, inspired, and catalyzed action from thousands of investment firms, early to late-stage innovators, established global companies, industry thought leaders, national policymakers, incubators & accelerators, and researchers that have had substantial, positive impacts on investments, businesses, people, and our planet. EarthX is an international nonprofit environmental organization dedicated to educating and inspiring people and organizations to take action towards a more sustainable future worldwide.

PHOENIX AZ — Deep Isolation, a leading innovator in nuclear waste storage and disposal solutions, will present its three latest publications and offer insights into site screening criteria at Waste Management Symposia 2024. The conference is taking place at the Convention Center in Phoenix, AZ from March 10 through March 14, 2024.

On March 12 at 8:55 am, Deep Isolation’s Head of Engineering, Jesse Sloane, will discuss our project to develop a Universal Canister System.   Working in conjunction with NAC International Inc., the University of California, Berkeley, and Lawrence Berkeley National Laboratory, Deep Isolation is leading the charge to develop an integrated waste management system for the safe transport, storage, and ultimate disposal of waste streams coming from advanced fuel cycles and advanced reactors.  Project UPWARDS will deliver a Universal Canister System design, a functional prototype to be used for future testing, and a set of generic waste acceptance criteria, providing for true universality by allowing for the disposal of a variety of waste streams in both conventional mined and novel deep borehole repositories.

“The Project UPWARDS team has made considerable progress through the first half of the project.  We expect the Universal Canister System to set a new standard for the advanced reactor industry, enabling companies to plan for use of a fully integrated waste management system prior to their new reactors even coming online,” Sloane said.  “Deep Isolation has worked diligently to create solutions for the disposal of legacy nuclear waste, a challenge that has hindered the global nuclear power industry for decades.  As we continue advancing these solutions, we are committed to proactively clearing these hurdles for the next generation of nuclear power.”

On March 12 at 1 pm, Dr. Ethan Bates, Director of Systems Engineering, will present a paper outlining Deep Isolation’s newly developed site evaluation framework for deep borehole repositories. “One of the first questions any nation will ask when considering deep borehole disposal is what types of site properties and host rocks are needed.  In this paper we developed a systematic and phased approach to answering this question, factoring in how the level of knowledge on potential sites and the repository design will change over time,” Dr. Bates said.

On March 12 at 2:45 pm, Chris Parker, Managing Director of Deep Isolation EMEA Limited, will present “Progress Towards the Demonstration of Deep Borehole Disposal”.  At Waste Management Symposia 2023, a group of international stakeholders from government and industry came together to announce the establishment of an independent, multi-national, non-profit organization: the Deep Borehole Demonstration Center.  He will describe the progress the Center has made over the last year, and outline the multi-year, phased program of work that the Center is looking to deliver.

CEO Liz Muller will also present the company and its technology to the Arizona section of the American Nuclear Society on Monday, March 11th at 6 pm at The Old Spaghetti Factory. Please feel free to RSVP by emailing or texting (623) 377-2827. More information is available in this flyer

The Waste Management Symposia annual conference is a premier event that gathers 3,000 attendees from more than 30 countries to discuss and share ideas on many crosscutting topics including: robotic handling, remote systems, new technologies, radioactive and hazardous waste characterization, treatment storage, packaging, transportation, and disposal, engineering design and construction, environmental laboratories, decontamination, decommissioning, and environmental remediation – as well as emerging topics such as small modular reactors, clean energy, Science, Technology, Engineering, and Math (STEM).

Earlier this month, Deep Isolation announced the completion of its first full-size prototype canister in collaboration with its partners, for the safe geological disposal of spent nuclear fuel and high-level radioactive waste in deep boreholes. The corrosion-resistant canister, measuring over 16 feet in length and weighing close to 4,500 pounds, has been manufactured by the Nuclear Advanced Manufacturing Research Centre (Nuclear AMRC) in Rotherham, with support from Lancashire-based Graham Engineering. As part of this work, the canister design, driven by US fuel cycle specialist NAC International Inc., has been verified as meeting current UK regulatory requirements.
