What is a Nuclear Power Plant Emergency?

Nuclear power plants use the heat generated from nuclear fission to convert water to steam to produce electricity. An emergency situation at a nuclear power plant could result in a release of dangerous levels of radiation that could affect the health and safety of persons near the nuclear power plant.

Why Prepare?

There is one nuclear power plant (Pilgrim Nuclear Power Station) in Massachusetts and two others (Seabrook Nuclear Power Station & Vermont Yankee Nuclear Power Station) just over the state borders that could impact parts of Massachusetts. The potential danger from an emergency at a nuclear power plant is a release of, or exposure to radiation.


People that live, work, or vacation within 10 miles of a nuclear power plant should be prepared for an emergency at a nuclear power plant and be familiar with the Emergency Planning Zone's (EPZ) emergency plans and procedures.
