- Extensive security features,
- Multiple back-up safety systems, and
- Highly trained staff and security forces
Members of our security forces are often former military and police members, and are required to complete rigorous training and receive re-qualification training each year.
In addition, our security personnel are regularly subject to real-world challenges of simulated "force-on-force" attacks. Experts working with the U.S. Nuclear Regulatory Commission are responsible to plan, coordinate, and assess plant security response to a wide variety of simulated attacks.
Security Zones Around Nuclear Plants

All U.S. nuclear power plants have three security zones with increasing levels of physical security measures to prevent intruders from accessing the plant.
- Owner-Controlled Area: A buffer zone surrounding the plant's Protected Area, controlling access to the property.
- Protected Area: Areas closer to the power plant have multiple physical barriers and state-of-the-art electronic systems that prevent or detect any intrusion attempts by outsiders. Access to this area is highly restricted, involving personnel screening and multiple-entry checkpoints.
- Vital Area: Located within the Protected Area, the Vital Area houses the reactor buildings and contains additional combinations of physical barriers, electronic systems, and administrative controls to protect the nuclear units.
The nuclear power industry has the highest security standards of any U.S. industry.
