Safety & Emergency Planning for SONGS Decommissioning

We have no higher priority than safety at San Onofre. As one of our decommissioning principles, every day our focus is to protect the health and welfare of our employees and the public.


Emergency Planning During Decommissioning

The Nuclear Regulatory Commission has approved a revised emergency plan for the San Onofre nuclear plant that reflects the plant's permanent shutdown. Most potential accident scenarios related to an operating plant are no longer possible at San Onofre.

Community Alert Siren System

The Community Alert Siren System is no longer needed for San Onofre due to its decommissioning. However, local jurisdictions continue to maintain the system for other local events.

Plant Safety & Security

Nuclear power plants are well-designed, operated by highly trained personnel and defended by armed security officers. Each nuclear power plant has extensive security measures in place to protect the facility from intruders. Learn more about security measures at San Onofre.

Since Sept. 11, 2001, the nuclear energy industry has substantially enhanced security at nuclear plants. Click here to learn more about these measure.
