NRC License Amendment for Use of FLOPAM AN 934 SH in Uranium Mine Waste Remediation

The U.S. Nuclear Regulatory Commission (NRC) is considering a license amendment for the use of a specific flocculant in uranium mine waste remediation: - Government Buyer: - U.S. Nuclear Regulatory Commission (NRC) - Office of Nuclear Material Safety and Safeguards - Division of Spent Fuel Storage and Transportation - OEMs and Vendors: - SNF Inc. (manufacturer of FLOPAM AN 934 SH) - DISA Technologies, Inc. (licensee and user) - Products/Services Requested: - FLOPAM AN 934 SH, a solid anionic polyacrylamide flocculant (APAM) - Part number: AN 934 SH - Used in high-pressure slurry ablation (HPSA) process for uranium mine waste remediation - Estimated usage: approximately 150 grams per ton of fines concentrates (no total quantity specified) - Unique or Notable Requirements: - Amendment covers use of FLOPAM AN 934 SH and similar solid APAMs only - Any alternative flocculant formulations require additional NRC review - Site-specific environmental assessments required before use at each location - Compliance with applicable environmental discharge standards is mandatory

Description

The U.S. Nuclear Regulatory Commission (NRC) is considering an amendment to source materials license SUA-1605 for DISA Technologies, Inc. to allow the use of SNF Inc.'s FLOPAM AN 934 SH, a solid anionic polyacrylamide flocculant, in the high-pressure slurry ablation (HPSA) process at abandoned uranium mine waste sites. The amendment aims to improve the separation of solid materials from process water, increasing the concentration of uranium and thorium in fines concentrates. The NRC has issued a generic environmental assessment and finding of no significant impact, concluding that the proposed amendment would not significantly affect the quality of the human environment. Site-specific assessments will be conducted upon submission of premobilization notifications by DISA.
