Nuclear Regulatory Commission (NRC) will address concrete degradation at Seabrook nuclear power plant Wednesday.
The NRC and NextEra Energy will host the public event to discuss the issue.
The first report of concrete degradation at the facility was reported in May 2010 by NextEra Energy, owners and operator of the plant, according to a report from Union Leader.
This type of degradation, caused by a reaction to alkali-silica, is the first reported at a nuclear power plant in the U.S.
If not properly addressed the reaction can cause micro-cracks in the concrete.
In May 2012, NRC issued a confirmatory action letter to the utility. On Oct. 9, NRC announced that the action letter was being closed out after the agency confirmed that the proper actions were being met.
NRC will continue to provide oversight and monitor the company’s ongoing actions to resolve the issue, including a review of the results of an ongoing testing program being conducted at the University of Texas-Austin, the report said.
