Deep Isolation Nuclear, Inc. 8-K

What Happened
On January 28, 2026, Deep Isolation US LLC, a wholly owned subsidiary of Deep Isolation Nuclear, Inc., entered into a Master Services Agreement (MSA) with Halliburton Energy Services, Inc. Under the MSA, Halliburton will construct and provide access to a full-scale-at-depth demonstration test well at Halliburton’s site in Cameron, Texas to demonstrate Deep Isolation’s Universal Canister System and deep borehole drilling solution. The demonstration will not involve nuclear waste. Deep Isolation expects construction, preparation and the initial demonstration to take approximately three years.

Why It Matters
This agreement funds and provides access to a major, multi-year field demonstration — a key commercialization milestone for Deep Isolation’s deep borehole containment approach. For investors, the filing signals concrete progress on technology validation and de-risking, but the 8-K does not disclose financial terms or specific costs, so investors should watch future filings and disclosures for budget, milestones, and any material changes to schedule or scope.
