Seabrook is the host community for the Seabrook Nuclear Power Station — a 1,244 MW pressurized water reactor on the Atlantic coast of New Hampshire. The plant sits directly on the ocean and generates power for much of New England. Seabrook is at the innermost ring of the Emergency Planning Zone, and residents have specific sheltering and evacuation protocols. The plant's coastal location also makes it vulnerable to hurricane storm surge and nor'easter flooding that could affect cooling water intake infrastructure.
