Nuclear Power Plants in Massachusetts
The NRC lists no active power reactor unit in Massachusetts. It lists one site undergoing decommissioning.
Sites undergoing decommissioning
From the NRC's list of power reactor sites undergoing decommissioning. A site's status can change, so check its NRC page.
If you live near a plant
The NRC describes two emergency planning zones around a power reactor site, and says their size and shape vary by plant:
- About 10 miles (plume exposure). Plans aim to avoid or reduce dose, for example from breathing radioactive particles. Actions include sheltering, evacuation and potassium iodide pills where appropriate.
- About 50 miles (ingestion exposure). Plans aim to avoid or reduce dose from eating or drinking radioactive materials, including a ban on contaminated food and water.
These zones are described for power reactors. Ask your state office whether any applies to a site undergoing decommissioning.
To find out what applies to your address, ask your county emergency management office or the Massachusetts Emergency Management Agency. A plant in a neighboring state can also cover your area, so check plants near your state line too.
In a nuclear power plant emergency, CDC says you may be asked to get inside a building and shelter rather than leave. Follow the instructions you are given. See what families should know and what FDA and CDC say about potassium iodide.
