Around the world, about 490,000 metric tons of radioactive spent fuel is temporarily stored in pools and dry casks above ground. No spent nuclear fuel anywhere in the world has yet been placed in a permanent repository.

It is time to consider alternative options to address an issue that is growing in scope and scale. 

Estimated size of nuclear waste inventory worldwide.


Knowing that something must be done in the U.S. and around the world to dispose of nuclear waste, Deep Isolation founders Elizabeth Muller and Richard A. Muller brought together the innovation and agility of a Silicon Valley startup with nuclear and scientific expertise to offer an innovative solution to the impasse of nuclear waste disposal that prioritizes environmental protection and community partnerships.

Core Values

At Deep Isolation, we maintain a core value of putting stakeholders and community engagement at the center of our solution design.  Our focus on public and stakeholder engagement reflects “best practice” and lessons learned from past experience in the field of nuclear waste disposal.  We uphold that greater participation from communities can bring mutually beneficial solutions to address spent nuclear fuel.

A New Approach

In the US, 1 out of every  3rd person lives within 50 miles of a nuclear waste storage site. With no present solution yet approved by the U.S. Government for permanent underground disposal in 2015, our founders thought to apply directional drilling technology to nuclear waste management. And after two years of technical due diligence and stakeholder listening, they realized that this private innovation could have something to offer.  Deep Isolation entered the market in the Spring of 2018 and continues to gain traction through a public-private partnership approach.


Funding for Deep Isolation comes primarily from concerned citizens and successful entrepreneurs, as well as environmentalists. Our lead investor is NAC International, a leading nuclear fuel cycle consulting and technology solutions. Our investors are people who care about this issue and wish to support innovation that can bring forward additional disposal options.
