The Nuclear Regulatory Commission has approved a license application submitted by Disa Technologies Inc. to use High-Pressure Slurry Ablation technology to remediate abandoned mine waste at inactive mine sites. The licensing approval process was completed in six months, rather than the 18-24 months it might have taken under a previous schedule. Upon receipt of Disa’s application to perform abandoned uranium mine waste remediation, and following the Commission’s direction, NRC staff reviewed and approved the application. On April 11, the NRC staff issued an acceptance review letter to Disa with a schedule for the detailed technical review and developed and deployed a clear, first-of-its-kind regulatory framework resulting in the agency’s approval to perform the remediation activities safely. High-Pressure Slurry Ablation is a mechanical process that separates minerals in mine waste into different parts. One part contains the uranium that can be recovered or disposed of in a licensed disposal facility. The other part will be left onsite.
