In a recent policy paper, the NRC staff re-evaluated Category 3 source security and accountability, making recommendations to the Commission informed by analysis of relevant data, stakeholder feedback, as well as costs/benefits of potential changes.
The NRC staff's re-evaluation addressed concerns about a potential malefactor obtaining a valid license using a fictitious company or by providing false information, altering a valid license to obtain more or different radioactive material than authorized or to counterfeit a license to obtain radioactive materials illicitly, or aggregating Category 3 sources to a Category 2 quantity of radioactive material.
The NRC staff recommended rulemaking to amend 10 CFR Parts 30, 40, and 70 to require safety and security equipment to be in place before granting a license for an unknown entity and to clarify license verification methods for transfers involving quantities of radioactive material that are below Category 2 thresholds.
Significantly, the NRC Staff did not recommend license verification through the License Verification System (LVS) or regulatory authority for transfers of Category 3 quantities of radioactive material, inclusion of Category 3 sources in the National Source Tracking System (NSTS), additional security requirements to prevent aggregation of Category 3 sources to a Category 2 quantity of radioactive material, or limiting the quantity of byproduct material in a generally licensed device.
