// Strategic Significance

Seabrook Nuclear Plant on the New Hampshire Atlantic Coast generates 1,300 megawatts for the New England grid. The plant is experiencing concrete degradation due to alkali-silica reaction a chemical process that causes concrete to expand and crack over time. Seabrook is the first US nuclear plant diagnosed with this condition which could affect long-term structural integrity. Noreaster storm surge directly threatens the Atlantic Coast site.

// Civilian Impact Assessment

Rockingham County with 310,000 residents and the greater Boston metro downwind. Seabrook is experiencing concrete degradation from alkali-silica reaction creating structural concerns. Noreaster storm surge threatens the Atlantic Coast site. New England grid depends on Seabrook baseload power.

// Evacuation & Shelter Guidance

I-95, NH Route 107, Ocean Boulevard. Rockingham County Emergency Management and NRC coordinate nuclear emergency noreaster and concrete degradation protocols.
