US-based Deep Isolation Nuclear has started site preparation and well pad construction at the Deep Borehole Demonstration Center near Cameron, Texas. This marks the transition from engineering design into field execution for the world’s first full-scale, at-depth deep borehole nuclear waste disposal demonstration.
The project is a major component of Deep Isolation’s Commercialisation Pilot, supported in part by a federal grant under the US Department of Energy’s (DOE’s) ARPA-E SCALEUP Ready programme, which provides critical bridge funding to advance lab-tested tech into commercial-scale deployment.
The goal is to demonstrate the end-to-end handling, emplacement, and retrieval of Deep Isolation’s patented Universal Canister System (UCS) using non-radioactive simulant packages. Deep Isolation is collaborating with industry giants including Halliburton (providing subsurface and well construction expertise), Amentum, NAC International, and Occlusion Nuclear Solutions.
Well pad and surface infrastructure construction is forecasted to finish in December 2026 after which drilling, casing, and cementing operations for the demonstration borehole will begin. Inmid-2027, the team expects to test the surface handling equipment to place and retrieve canisters from the wellbore.
The directional drilling technology leverages established oil and gas drilling practices to bury high-level nuclear waste over a mile deep inside rock isolated from the biosphere, offering a modular solution to one of the nuclear industry’s longest-standing hurdles.
Deep Isolation Begins Surface Pad Construction for First Full-Scale Deep Borehole Nuclear Waste Disposal Demonstration
“Beginning site preparation and well pad construction is a significant execution milestone for the Commercialisation Pilot,” said Jesse Sloane, Executive Vice President of Engineering at Deep Isolation. “It allows us to transition from engineering and planning into field operations, where we can demonstrate our technology at full scale and collect the operational data needed to support commercialisation.”
Steve Haden, Senior Vice President for Project Management at Halliburton noted: “The deep borehole Commercialisation Pilot highlights how proven subsurface engineering and well construction experience can support new applications. Halliburton brings subsurface, drilling, and well construction experience developed through decades of complex projects, and we look forward to supporting the execution of the demonstration well.”
