Palo Verde Nuclear Generating Station
Emergency Alert System (EAS)
Specially designated radio and TV stations that will broadcast safety information in the event of an emergency.
Emergency Classification Levels (ECL)
The federal government has designated four classifications for incidents at nuclear power plants. Each classification corresponds to the degree of seriousness of an incident.

Emergency Planning Zone (EPZ)
The area designated by the federal government within a 10-mile radius of a nuclear power plant for which plans have been put in place to protect people in the event of a radiological emergency.

A protective action intended to prevent or reduce exposure to radioactive materials. In an evacuation you would be instructed to leave your home and go outside the Emergency Planning Zone to a Reception and Care Center.
Potassium Iodide (KI)
KI is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting it from radiation injury. In the event of a radiological emergency you may be given KI and instructed to take it. KI should only be taken when directed by public officials.
Protective Action
Any action taken to protect the public's health in response to an emergency. Protective actions in a radiological emergency could include sheltering (staying indoors), evacuating the area and/or taking KI - Potassium Iodide.
Radiological Emergency
An emergency where radioactive materials in significant concentrations escape into the environment. If concentrations of the materials are high enough, they could be dangerous to health.
Radiological Release
Introduction or leak of any radioactive materials into the environment.
Reception and Care Center (RCC)
A location outside of the Emergency Planning Zone where people who have evacuated can go. At the Reception and Care Center, evacuees would receive initial assistance, including personal monitoring for radiation contamination, receive Potassium Iodide (KI), and shelter if necessary.
This is a protective action in which you are instructed to stay indoors with windows and doors tightly shut and all ventilation systems turned off. Under certain circumstances it is the better way to limit exposure to radioactive materials.
Siren Alerting System
There are 48 sirens placed within the 10-mile Emergency Planning Zone surrounding Palo Verde. In the event of an emergency at Palo Verde the sirens will sound for approximately three minutes with a steady high-pitched sound.
