Millstone Nuclear Power Station Emergency

A nuclear power plant is designed and constructed to provide electricity while protecting the health and safety of the public and environment. There are many levels of protection and barriers, each with several backup systems. A nuclear power plant cannot explode like a bomb because the fuel is not very concentrated. The fuel is cooled in a closed water loop system inside a device called a reactor within a reinforced concrete containment building.

Backup Safety Systems
In the unlikely event of a serious nuclear power plant emergency, many backup safety systems would help slow or stop the emergency. A nuclear power plant emergency would not happen quickly and would likely take hours or days to develop. This would give state and town officials sufficient time to direct necessary public protective actions in a timely manner with your cooperation.

Taking Action
Upon hearing the sirens, residents are asked to proceed to the nearest TV or radio to get the specific information that will be passed via the Emergency Alerting System.
