Radiological Preparedness

​The California Governor's Office of Emergency Services (Cal OES) mission for radiological emergencies is to support local government efforts to protect the public during a radiological emergency.

Radiological Preparedness Unit

The Radiological Preparedness Unit (RPU) in the Cal OES consists of the staff, expertise, authority and program funding necessary to support local governments in their effort to plan for, prepare for and respond to radiological incidents that threaten lives, property and the environment.  The RPU provides an effective and efficient emergency management system for radiological incidents by coordinating with private entities, federal, tribal, State and local government organizations.
The goal of the RPU is to protect the public, property and the environment from the possible harmful effects of radiation from transportation accidents, incidents at nuclear power plants and other fixed facilities.
The RPU is responsible for the following programs:

The California Radiological Emergency Preparedness (CalREP) Program directs the State response to radiological incidents in California.  The CalREP Plan is part of the State Emergency Plan and serves as the umbrella document that brings together the State Nuclear Power Plant Emergency Response Plan, the radiological transportation plans, the State Dose Assessment Center Plan and other associated plans and procedures. 

The Nuclear Power Plant (NPP) Program covers emergency planning issues related to the State’s two nuclear power plants – Diablo Canyon Power Plant (DCPP) in San Luis Obispo County and the San Onofre Nuclear Generating Station (SONGS) in San Diego County.  The NPP Program also continues coordination with the two retired nuclear power plants - Humboldt Bay Nuclear Power Plant in Humboldt County and Rancho Seco Nuclear Generating Station (RSNGS) in Sacramento County.  The NPP program works with federal, state, local and utility officials in emergency planning, training and exercises to test emergency readiness.
The Waste Isolation Pilot Plant (WIPP) Program provides for coordination with the U.S. Department of Energy (DOE), other state agencies and local governments regarding the transportation of radioactive wastes from defense-related facilities that conducted research, development and production of nuclear weapons.  Cal OES provides for the procurement of and training on, radiological monitoring and detection equipment issued to local government first responders along the DOE WIPP transportation routes.
Naval Nuclear Propulsion Program (NNPP) technology is among the most sensitive and valuable military technologies currently in use in the United States. Although the NNPP facilities and ships located in the San Diego Bay area are not within the State and local jurisdictions, the NNPP will work closely with the State of California and local governments in emergency preparedness and has an unprecedented emergency preparedness outreach program in California.  California continues to work with the NNPP to make both our programs work together in supporting the local jurisdictions’ emergency preparedness efforts.
