Company Overview

Nuclear power contributes over 10% of the world’s power needs. From the 500 reactors built around the world, the growing inventory of nuclear waste is over 450,000 metric tons and is increasing by ~12,000 tons each year. In the US, there is currently ~$40 Billion in the Nuclear Waste Fund, with no active program to dispose of the 80,000 tons of nuclear waste. Many countries are actively seeking new options as no country anywhere in the world has ever disposed of high-level waste or spent nuclear fuel. A new approach is needed.

Nuclear waste disposal is a $500 billion worldwide market.

Deep Isolation is the first private company to offer a solution to dispose of nuclear waste in safe, permanent deep geologic repositories. A solution that is proven, demonstrated and primed to disrupt and dominate in this untapped market.

Deep Isolation brings recognized expertise, a unique approach, and a 4-year head start on any competition:

  • Proven technology with 30+ patent filings
  • Recognized leader in tailored community engagement
  • Reliable program management demonstrated
  • Delivery capacity backed by the expertise of partners like Bechtel and NAC
  • First feasibility assessment contracts in process

Deep Isolation combines scientific and nuclear expertise with sophisticated stakeholder engagement skills to work alongside communities to design and deliver an equitable and environmentally protective solution.

Deep Isolation Technology

Deep Isolation’s solution leverages proven directional drilling technology to place and retrieve nuclear waste in a long, horizontal drillhole thousands of feet underground within highly stable geological formations.

The repository implementation begins with drilling a vertical access hole thousands of meters deep. At depth, the borehole would take a gradual turn and level to a horizontal position. The drilled hole then continues horizontally with a slight upward tilt (1°–3°) for several hundred to a thousand meters.

Specially designed and sized corrosion-resistant waste canisters containing the nuclear waste are then lowered into the drillhole and placed end to end within the horizontal section. These could be retrieved if necessary but, in this form, are considered safely isolated and disposed of. When the disposal state is deemed final, the repository would be permanently closed, and the vertical drillhole would be backfilled and sealed with rock, cement, bentonite, and other impermeable materials.

Community and Stakeholder Engagement

Deep Isolation is committed to engagement and collaboration with local communities and governments in order to determine if deep geological disposal is not only right for that location but supportive of their community vision. Through a fully immersive and two-way dialogue with local communities and decision-makers, we facilitate informed consent on behalf of the community as well as a sense of value for partnership with Deep Isolation.

Deep Isolation demonstrates its patented technology to dispose of nuclear waste.
