RE: NWMI Non-Proprietary Write-up of Section 4.4.2.7.1 - Recovery of Off-Specification Uranium Carolyn, Thank you for the information below. Regarding the clarification response to RAI ALT-2A (location of support buildings). I want to confirm that that the diesel generator building and waste management building at the MURR alternative site be located within the 1 ha (2.5 acre) partially paved parking lot?

[External_Sender] NWMI Non-Proprietary Write-up of Section 4.4.2.7.1 - Recovery of Off-Specification UraniumNancy, Per your request during yesterday's weekly meeting, below is the revised public version of Section 4.4.2.7.1 - Recovery of Off-Specification Uranium. Please let me know if you have any other clarifications. NWMI Non-Proprietary Write-up of Section 4.4.2.7.1 - Recovery of Off-Specification Uranium Off-specification uranium can be generated during target fabrication in the target fabrication system. The off-specification uranium is anticipated to be generated intermittently. The general approach to deal with off specification uranium is for it to be recycled and processed into fresh LEU target material. The exception is if the uranium is not suitable for LEU target 2material production (e.g., the enrichment is too low). Any LEU material with low enrichment, it will be stabilized, packaged for secured storage and then returned to DOE per the Uranium Lease Take Back contract. For the preliminary design, the off-specification uranium operations will be sized to accommodate 25 percent of the total throughput. An allowance has been made in the mass balance for the generation of off-specification uranium. There are three potential areas in the target fabrication system that off-specification uranium may be recovered including:
- Uranium that has been irradiated, recovered during irradiated target processing, and recycled into new LEU target material may eventually be unacceptable for continued 99Mo production due to the burnup of 235U and buildup of unwanted uranium isotopes. This material, which is recovered as uranyl nitrate, will be converted into a stable form for disposition and packaged for secured storage and returned to DOE.
- If uranium is identified as being off-specification due to the presence of chemical impurities, the material will be recycled to the Uranium Recycle System within the hot cells. The purified uranyl nitrate will then be recycled to the target fabrication process.
- If LEU target material is identified as being off-specification after being produced (e.g., doesn't meet process requirements), the material will be recycled to the uranium dissolution step in the Target Fabrication System.
