SEABROOK — The Nuclear Regulatory Commission staff has issued a draft safety evaluation for a license amendment request from the Seabrook nuclear power plant’s owner, NextEra Energy, that seeks to address concrete degradation caused by alkali silica reaction.
ASR is a chemical reaction that causes concrete to expand and potentially reduces structural integrity over time. After it was first detected at the plant in 2009, the commission determined the affected structures could continue operating safely.
The final decision on the Seabrook license renewal application will come after the completion of the Atomic Safety and Licensing Board hearing on the license amendment request, which is now expected to take place in summer 2019.
