Debate grows over New Hampshire’s plan to expand nuclear energy - vnews.com
At the direction of Republican Gov. Kelly Ayotte, New Hampshire's executive branch spent the summer of 2026 developing a 'road map' to expand nuclear power in the state, following a March executive order and a joint statement by all six New England governors championing nuclear energy. The debate intensified as lawmakers filed a flurry of nuclear bills, Ayotte vetoed at least one (House Bill 221) over ratepayer concerns while working on a compromise within a 'must-pass' energy bill (HB 1738), and experts openly questioned whether new nuclear generation would actually lower costs for New Hampshire ratepayers given the state is already a net energy exporter. The backdrop includes the aging Seabrook Station plant, concerns over concrete degradation, and the unresolved question of long-term radioactive waste storage.
How each side frames it
left
"Ayotte, a Republican, said the language she vetoed also appears to be attached to legislation pending before a committee of conference"
"despite lingering public wariness of risks"
"Questions about degraded concrete at the Seabrook Nuclear Power Station have prompted three Massachusetts lawmakers to call for a delay in the coastal New Hampshire facility's federal relicensing."
"public safety could be threatened by a premature approval of the license amendment"
center
"Just because an asset is located in the state of New Hampshire doesn't mean we buy the energy or benefit from the energy"
"Nuclear doesn't care about the weather. It just runs"
"spent fuel, which is dangerously radioactive for thousands of years, have failed"
"still stirring plenty of emotions among opponents and supporters whose clashes made Seabrook the face of the national debate over nuclear energy"
"that figure ballooned to $4.3 billion for the first unit alone by the time it was completed in 1986"
right
"Nuclear energy is constant and reliable"
"investing in more nuclear power could lower costs for ratepayers and reduce emissions"
"It's carbonless, we need more energy, we have aging facilities, we rely heavily on Canada"
"This isn't an immediate play, right? But we have to position New Hampshire for these new technologies."

What's actually true?
[verified] Gov. Ayotte issued a March executive order directing the state energy department to push for nuclear power development
[verified] All six New England governors signed a joint statement championing nuclear power
[verified] Seabrook Station is one of only two remaining nuclear plants in New England
[verified] Seabrook is the only nuclear plant in the country where alkali-silica reaction (ASR) concrete degradation is known to be occurring
[unverified] New Hampshire is a net exporter of energy, generating more than residents and businesses use
[unverified] Over 50% of electricity in New England is generated with natural gas
[verified] Ayotte vetoed House Bill 221 citing concerns about its impact on ratepayers
[unverified] Seabrook cost $6.2 billion by the time its sole reactor came online commercially in August 1990
The narrative clash
Whether nuclear expansion will lower costs for New Hampshire ratepayers
Left: investing in more nuclear power could lower costs for ratepayers and reduce emissions
Right: New Hampshire ratepayers, who would likely finance it, would not see a direct, local benefit, although there would be a regional one
Safety of Seabrook's degraded concrete
Left: public safety could be threatened by a premature approval of the license amendment
Right: NRC staff conducted a lengthy review of NextEra's plan to manage the ASR issues, and found it acceptable
