Nuclear Regulatory Commission
The U.S. Nuclear Regulatory Commission (NRC) is considering an amendment to source materials license SUA-1605, which the NRC issued to DISA Technologies, Inc. (DISA) in 2025 for the operation of its high- pressure slurry ablation (HPSA) technology to remediate abandoned uranium mine (AUM) waste. If approved, the amendment would modify the license to allow the use of SNF Inc.'s FLOPAM AN 934 SH (FLOPAM), an anionic, polyacrylamide flocculant (APAM) in solid (powder or granular) form, in the HPSA process at abandoned uranium mine waste sites. The NRC staff is issuing a generic environmental assessment (EA) and finding of no significant impact (FONSI) associated with the proposed license amendment. This generic EA supplements the NRC staff's 2025 generic EA for the license issuance.
