The Nuclear Regulatory Commission has issued an environmental assessment and finding of no significant impact to Disa Technologies for company’s use of its NRC-licensed high-pressure slurry ablation (HPSA) technology to remediate abandoned uranium mine (AUM) waste at the Mary Ann AUM waste pile site in Montrose County, Colo.

Disa Tech, a Wyoming-based mineral processing company, submitted a premobilization notification to the NRC in March to use its HPSA technology at the Mary Ann site. The NRC is considering approval of the PMN, which would officially allow HPSA operations to proceed.

The noticeable exuberance within the nuclear community as a whole appears to have spilled over into the waste management sphere as well, judging from the 2026 Waste Management Conference, held March 8–12 in Phoenix, Ariz., and sponsored by Waste Management Symposia.

The theme of this year’s conference was “Efficient and Innovative Nuclear Materials and Technology Solutions,” and many of the scheduled panels and technical sessions revolved around how nuclear growth and technological advancements are affecting the back end of the fuel cycle, as well as how the cleanup of legacy sites is enabling new nuclear development.
