Should the U.S. bury high-level nuclear waste more than a mile deep underground?

Deep Isolation Nuclear started site preparation and well pad construction at the Deep Borehole Demonstration Center near Cameron, Texas. The project is part of the company's Commercialisation Pilot and is partly supported by a federal grant under the U.S. Department of Energy's ARPA-E SCALEUP Ready programme.

Why it matters

The demonstration tests whether high-level nuclear waste can be placed more than a mile underground using directional drilling methods adapted from oil and gas. Its outcome bears on how the country might handle long-lived radioactive waste that currently lacks a permanent disposal site.

The demonstration will bury high-level nuclear waste over a mile deep using directional drilling, with well pad construction forecast to finish in December 2026. Drilling and casing operations have not started, and surface handling equipment testing is expected only in mid-2027.

The players

Deep Isolation Nuclear

Deep Isolation Nuclear is the company developing directional drilling technology to bury high-level nuclear waste deep underground.

Halliburton

Halliburton is an energy services company providing subsurface and well construction expertise to the project.

U.S. Department of Energy

The U.S. Department of Energy is the federal agency whose ARPA-E SCALEUP Ready programme provides partial grant support for the demonstration.

The details

The demonstration will show end-to-end handling, emplacement, and retrieval of the Universal Canister System using non-radioactive simulant packages. Deep Isolation is working with Halliburton, which provides subsurface and well construction expertise, along with Amentum, NAC International, and Occlusion Nuclear Solutions.

November 3, 2026: Article reports the start of site preparation and well pad construction.
December 2026: Well pad and surface infrastructure construction is forecast to finish.
Mid-2027: Surface handling equipment testing is expected.

The Big Picture

The project is funded in part through the ARPA-E SCALEUP Ready programme, which supports moving energy technologies toward commercial use. The demonstration's progress will indicate whether deep borehole disposal can advance beyond the pilot stage.

Residents near Cameron may see surface construction activity at the demonstration site through December 2026. The project does not yet affect the disposal of waste held at existing facilities, as the demonstration is limited to non-radioactive simulant packages.

The takeaway

Deep borehole disposal remains at the demonstration stage, and its test results in 2027 will indicate whether the approach is viable. Readers following nuclear waste policy can track the project's milestones as they are reported.
