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.”

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.

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.

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.

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.
