C-10, in light of the successful license amendment and license renewal of Seabrook Station, filed an “emergency petition” with the Nuclear Regulatory Commission, seeking review of those decisions by the Commission.

C-10 Research and Education Foundation filed a petition related to concrete degradation caused by alkali-silica reaction (ASR) at Seabrook Station, Unit. C-10 asks us to exercise our inherent supervisory authority to direct the NRC Staff to address the safety risk posed by ASR in the Seabrook containment building before the Staff acts on the ASR license amendment request (LAR) or license renewal application filed by NextEra Energy Seabrook.

The NRC has issued its decision on this matter, which is attached below. The C-10 request was denied in full.
