Licensing Approach License Request: NWMI has submitted a Construction Permit Application to obtain a license for a production facility under Title 10, Code of Federal Regulations, Part 50 (10 CFR 50), Domestic Licensing of Production and Utilization Facilities
- Using guidance in NUREG-1537, Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors - Format and Content Proposed Action: Issuance of an NRC license under 10 CFR 50 that would authorize NWMI to construct and operate a 99Mo RPF at a site located in Columbia, Missouri RPF will:
- Receive irradiated low-enriched uranium (LEU) targets (from a network of university research or test reactors)
- Process irradiated LEU targets for dissolution, recovery, and purification of 99Mo
- Recover and recycle LEU to minimize radioactive, mixed, and hazardous waste generation
- Treat/package wastes generated by RPF process steps to enable transport to a disposal site
- Provide areas for associated laboratory and other support activities Exhibit NWMI-004 5
Additional RPF Licensing Activities Additional RPF operational activities are subject to other NRC regulations
- 10 CFR 70, Domestic Licensing of Special Nuclear Material, to receive, possess, use, and transfer special nuclear material
- Producing LEU target materials and fabrication of targets
- 10 CFR 30, Rules of General Applicability to Domestic Licensing of Byproduct Material, to process and transport 99Mo for medical applications
- Handling of byproduct material University reactor(s) and cask licensee(s) will amend their current operating licenses Exhibit NWMI-004 6

RPF Operating Characteristics (continued)
Ventilation System
- Ventilation system will be divided into four zones (Zone I, Zone II, Zone III, and Zone IV) with airflow directed from lowest to highest potential for contamination
- Zone I ventilation system will be initial confinement barrier (e.g., gloveboxes, tank hot cell, processing hot cells, and Zone I exhaust subsystem)
Biological Shield
- Provides an integrated system of features that protects workers from high-dose radiation generated during facility operations
- Will withstand seismic and other concurrent loads, while maintaining containment and shielding during a design basis event
- Primary function is to reduce radiation dose rates and accumulated doses in occupied areas to not exceed limits of 10 CFR 20 and RPF ALARA guidelines program Engineered Safety Features (ESF)
- Active or passive features designed to mitigate consequences of accidents and to keep radiological exposures to workers, the public, and environment within acceptable values
- Confinement is considered a general ESF Exhibit NWMI-004 9

RPF Consequences and Radionuclide Inventory Summary Primary consequences resulting from operation of RPF operations are radiological
- LEU target material production/fabrication
- Irradiated LEU target material processing (e.g., extract 99Mo and recycle and recover 235U)
- Radioactive waste materials processing RPF radionuclide inventory is based on a weekly throughput < 40 hr EOI of irradiated targets
- MURR 8 targets Legend
- OSTR 30 targets >100K Ci
>50K Ci Maximum radionuclide inventory >10K Ci
<10K Ci is based on accumulation in various systems dependent on process material decay times
> 40 hr EOI Exhibit NWMI-004 12
