A panel of federal judges has ordered a stricter monitoring plan for Seabrook Nuclear Power Plant’s issues with cracks in its concrete. 

The ruling comes from the Atomic Safety and Licensing Board, under the Nuclear Regulatory Commission.

It was issued in late August and made public Friday, about a year after a days-long hearing on the issue in Newburyport, Mass.


Seabrook Nuclear Power Plant remains offline after experiencing its second unexpected shutdown in about a week on Saturday night.

The incidents stem from the same system, which the plant's owner NextEra says it’s now trying to repair. Federal officials say the issue, known as a “manual scram,” has posed no danger to the public or plant workers.

Federal regulators expect to return to more frequent inspections at Seabrook Nuclear Power Plant as New Hampshire reopens its economy.

The Nuclear Regulatory Commission held the plant’s annual safety meeting by phone Wednesday.

Brice Bickett, the NRC’s regional branch chief for reactor projects, says inspectors should be on-site more often in the coming weeks than they have been since March.

“We’ll have more increased presence likely as early as next week,” he says. “But a lot of that remains subject to, as long as conditions don’t change.”


Seabrook Nuclear Power Plant is back online after an unplanned shutdown this past weekend.

Officials with the plant and the Nuclear Regulatory Commission say the incident did not pose a safety risk, and a watchdog group agrees.

The malfunction involved Seabrook’s control rods, which are used to fine-tune the fission reaction that powers the facility.

Watchdog groups and neighbors of the Seabrook nuclear power plant had what they called their day in court last week.

A federal administrative hearing with a panel of judges wrapped up Friday. It focused on whether Seabrook owner NextEra has adequately studied the degrading concrete at the plant.

The Nuclear Regulatory Commission approved NextEra's concrete monitoring plan based on that study and relicensed the plant earlier this year.

Last week, the Nuclear Regulatory Commission held a federal hearing to address cracks in the concrete at Seabrook Station Nuclear Power Plant. The safety and longevity concerns around this facility raise larger questions about the role of nuclear power as an alternative to fossil fuels.  We look at the role of Seabrook as part of the New England energy grid,, and the conversations around the use of nuclear energy now and in the future.

Activists are raising money to expand radiation monitoring around Seabrook Nuclear Power Plant. Federal regulators and the nuclear plant's owner, Florida-based NextEra, say Seabrook is operating safely.

But the nonprofit C-10 and other advocates are worried about cracks that are spreading in the facility's concrete. They also fear that rising seas and nuclear waste storage could cause public health threats in the future.

Federal regulators have approved a new license for Seabrook Nuclear Power Plant. It caps months of controversy over whether they'd delay the decision, ahead of a hearing this summer on cracks in the facility's concrete. 

That hearing will be between a local activist group and the Nuclear Regulatory Commission's law board.

Despite concerns from state officials, regulators have said the hearing is separate from their main licensing process.


Nuclear regulators say they plan to approve a new license for Seabrook Nuclear Power Plant next week.

It comes after an extra public hearing on concerns they were moving too quickly to approve the license extension through 2050.

Federal regulators still appear poised to re-license Seabrook Nuclear Power Plant, despite requests to delay.

A Nuclear Regulatory Commission hearing on the issue Wednesday night was packed with industry workers and residents from New Hampshire and Massachusetts.

The Nuclear Regulatory Commission will meet with Seacoast residents Wednesday night, ahead of an anticipated re-licensing for Seabrook Nuclear Power Plant.

Regulators set this hearing after facing backlash in January for saying they planned to grant Seabrook owner NextEra's request for a 20-year license extension.


The Nuclear Regulatory Commission will delay giving Seabrook Station permission to stay open until 2050, after facing pressure from lawmakers to take more public input.

Members of Congress raised concerns after the NRC said it would approve extending Seabrook's license this month – before an adjudicative hearing with a local watchdog group, the C-10 Foundation, this summer.

Seabrook Nuclear Power Plant is expected to get approval to continue operating through 2050 by the end of this month, after regulators finished determining the facility is safe to remain open.

Activists concerned about the facility’s safety say the decision is premature – but officials say those activists could still prompt changes in Seabrook’s license through a hearing this summer.

An independent group of scientists says they believe the concrete cracks at Seabrook Nuclear Power Plant are under control.

The report from the Advisory Committee on Reactor Safeguards agrees with earlier findings from the Nuclear Regulatory Commission.

The groups conclude that Seabrook's owner, NextEra, has a sufficient plan in place to monitor changes in and effects from the cracks over time.

A new report suggests New Hampshire's Seabrook Nuclear Power Plant will be essential to curbing the effects of climate change in the coming years.

Seabrook and Millstone Station in Connecticut will be the only two nuclear plants left in New England after next year.

They're also some of the most profitable nuclear plants in the country, according to the Union of Concerned Scientists.

A scientific panel will discuss cracks spreading in the concrete at Seabrook Nuclear Power Plant during a meeting Wednesday.

The independent committee advises the Nuclear Regulatory Commission on reactor safeguards.

They’ll hear from federal officials and from Seabrook’s owner, NextEra, on how they’re addressing the problem.

The concrete degradation is caused by a chemical reaction, known as ASR, and was found in 2010.


The Nuclear Regulatory Commission says they found no problems with the response to cracks in concrete at Seabrook Nuclear Power Plant during a recent inspection.

Their new report is another step forward in the power plant's bid to get its license renewed.

Critics of the Seabrook Nuclear Power Plant voiced concerns about the facility’s bid for a new license at an annual federal meeting in Hampton Wednesday night.

Officials with the Nuclear Regulatory Commission say the Seacoast plant is currently operating safely, despite cracks spreading through some of its concrete.

New Hampshire has high electricity rates, a major nuclear power plant, and has been in a years-long battle over hydropower development. How do these factors impact energy policy in the Granite State? We look at the state's newly updated energy plan, which prioritizes lowering rates, and has less to say about mass transit and renewable energy.

  Nuclear regulators are seeking the public's feedback on a plan to address concrete erosion at Seabrook's power plant.

NextEra Energy wants to extend its license for Seabrook Station by two decades. It must first show the Nuclear Regulatory Commission how it'll address alkali silica reaction, which causes concrete erosion.

The chemical reaction was found in several plant structures in 2010.

Federal regulators says they are ready to assess whether the Seabrook Station Nuclear Power Plant has a sufficient plan to address a chemical reaction affecting the plant’s concrete structures.

In 2009, staff at the Seabrook Station Nuclear power plant discovered something called an alkali-silica reaction happening in many of the plant’s concrete structures. The reaction, sometimes referred to as ‘concrete cancer,’ causes cracks and could threaten the structural integrity of the plant.
