Three Mile Island 1 reactor will get more attention from the feds after they found inadequate flood protection of safety equipment at the Middletown, PA, facility.
The Nuclear Regulatory Commission (NRC) said its inspectors last year discovered unprotected electrical conduits through which water could infiltrate the plant’s safety equipment in the event of a severe flood at the Exelon Generation Co. facility.
The NRC found the deficiency during one of the agency’s post-Fukushima reviews of U.S. reactors. After the discovery, Exelon sealed the conduits.
The NRC categorized the finding as an issue of low to moderate safety significance and will give the reactor “additional scrutiny” until “satisfactory corrective actions have been developed and implemented.”
