NRC Proposes $72,000 Civil Penalty Against Missouri-based Company
The Nuclear Regulatory Commission has proposed a $72,000 civil penalty against Curium US LLC, based in St Louis, Missouri.
NRC identified six violations of NRC requirements during inspections after two employees received occupational doses above NRC limits for nuclear workers at the company’s Noblesville, Indiana facility, which produces radiopharmaceuticals. The violations involved failures related to occupational doses, radioactive waste management procedures, surveys of radiation levels and potential radiological hazards, proper labeling of NRC-licensed material and annual audits. The proposed violations were documented in a September inspection report.
There was no impact on public health as a result of the incident or the underlying violations.
The NRC issued the enforcement action after reviewing the circumstances surrounding the proposed violations and considering the investigative efforts and extensive corrective actions the company has taken or plans to take to restore and maintain compliance with NRC requirements.
The company has 30 days to pay the fine, dispute it, or request involvement from a neutral third-party.
The U.S. Nuclear Regulatory Commission was created as an expert, technical agency to protect public health, safety, and security, and regulate the civilian use of nuclear materials, including enabling the deployment of nuclear power for the benefit of society. Among other responsibilities, the agency issues licenses, conducts inspections, initiates and enforces regulations, and plans for incident response. The global gold standard for nuclear regulation, the NRC is collaborating with interagency partners to implement reforms outlined in new Executive Orders and the ADVANCE Act to streamline agency activities and enhance efficiency.
