// Strategic Significance

Seabrook Nuclear Power Plant sits on the Atlantic Coast of New Hampshire just 40 miles north of Boston. It was one of the most controversial nuclear plants in US history with massive protests during construction. The 50-mile ingestion zone encompasses Boston and its dense northern suburbs — placing one of the largest US metro areas in a nuclear ingestion zone. The plant has direct Atlantic coast exposure to nor'easters and occasional hurricane remnants.

// Civilian Impact Assessment

The greater Boston metropolitan area falls within Seabrook's 50-mile ingestion zone — placing over 4 million people in the zone. Boston's dense population and complex geography create particularly challenging protective action planning. Atlantic seafood harvesting in the Gulf of Maine would be immediately restricted during any release event affecting the fishing economy of New England.

// Evacuation & Shelter Guidance

10-mile EPZ: Evacuate via NH-107 or US-1 away from coast. Monitor New Hampshire Homeland Security broadcasts. 50-mile zone: Greater Boston residents monitor Massachusetts EMA guidance. Atlantic seafood restrictions would apply across much of Gulf of Maine. Boston residents should have KI tablets — Massachusetts distributes them free within 10 miles but Boston falls in the ingestion zone.
