Deep Isolation Nuclear Inc. (DBHL) began site work for a nuclear waste disposal test in Texas. The project, part of its Commercialization Pilot, involves drilling and borehole operations. The company received up to $20M in funding from the U.S. Department of Energy's ARPA-E SCALEUP Ready program. Partners include Halliburton (HAL) and Amentum (AMTM). Well pad construction is expected to complete by December 2026.

Deep Isolation Nuclear, Inc. (OTCQB: DBHL) published a case study with Slovenia's Agency for Radioactive Waste Management (ARAO) on nuclear waste disposal. The study found integrating TRIGA II spent fuel into a proposed repository for the Krško Nuclear Power Plant could increase lifecycle costs by less than 0.5%. Deep Isolation's technology is designed for deep borehole disposal of nuclear waste, with over 100 patents issued.

Deep Isolation received a drilling permit from the Texas Railroad Commission for its full-scale, non-radioactive Commercialization Pilot. The permit allows the project to advance from design to construction and field activities. Partners include Halliburton and Amentum. According to the company's SEC filing, the pilot will demonstrate deep borehole disposal technologies.
