A Safe and Compliant Organization

We prioritize safety and regulatory compliance for the well-being of our staff, the public and the environment.

Through a wide range of activities, MURR employees build a strong nuclear safety culture and are committed to the core values and behaviors resulting from a collective commitment by leaders and individuals to emphasize safety over competing goals.

Safety is always the top priority

  • We work here and live in the community. Our efforts support the safety of our workforce, our families and the community.
  • MURR is licensed, regulated, and regularly inspected by the U.S. Nuclear Regulatory Commission (NRC) to ensure safety, security and compliance.
    • The reactor is operated by NRC licensed senior reactor operators and reactor operators, 24-hours a day, 7 days a week.
    • Operators attend training every six weeks in reactor operation, license requirements and emergency preparedness.
    • As an NRC regulated reactor facility MURR has a Corrective Action Program designed for continual improvements to safety and enhanced safety culture.
  • MURR’s staff are trained radiation workers who are routinely monitored for any potential exposure to radiation.
    • MURR has an extensive environmental monitoring program that surveys the environment, air and water effluents to ensure all remain well below regulatory standards.
  • All hazardous or radioactive material shipped from MURR is performed under the supervision of Department of Transportation (DOT) and International Air Transport Association (IATA) trained shipping professionals.
