Disa Technologies, Inc. High-Pressure Slurry Ablation Technology for Abandoned Uranium Mine Remediation

DISA Technologies, Inc.; Environmental Assessment and Finding of No Significant Impact

The Nuclear Regulatory Commission issued a generic Environmental Assessment and Finding of No Significant Impact for a proposed multi-site service provider license to DISA Technologies, Inc. to operate its high-pressure slurry ablation technology at abandoned uranium mine waste sites across 14 western states and the Navajo Nation. DISA's process separates uranium and thorium fines from mine waste rock; coarse material is returned to the site and fines are sent to licensed facilities. The NRC found no significant impacts provided site conditions match the generic EA assumptions, with site-specific review required via a premobilization notification 90 days before each mobilization.

Disa Technologies, Inc.; Draft Generic Environmental Assessment and Finding of No Significant Impact

The Nuclear Regulatory Commission published a draft generic Environmental Assessment and preliminary Finding of No Significant Impact for a proposed multi-site service provider license to Disa Technologies, Inc., authorizing use of its high-pressure slurry ablation (HPSA) technology to remediate abandoned uranium mine waste at sites across 14 western states and the Navajo Nation. The HPSA process separates uranium and thorium fines from mine waste rock; coarse residuals would be returned to sites and fines concentrates would go to licensed recipients. NRC concluded no significant impacts if site-specific conditions match generic EA assumptions, with site-by-site review required before each mobilization. Comments are due September 8, 2025.
