"The Nuclear Regulatory Commission (NRC) said on Tuesday it will increase oversight of Exelon Corp's 805-megawatt Three Mile Island nuclear power plant in Pennsylvania, to ensure that safety equipment is protected from flooding."

"As part of agency's numerous inspections of the nation's nuclear reactors following the Fukushima nuclear accident in 2011, the NRC said its inspectors identified an external flood barrier deficiency during a plant walk down last autumn.

Specifically, the NRC said the inspectors determined that the company had failed to identify and correct a problem involving pipes holding electrical cables.

The pipes, located in the plant's air intake tunnel, were not adequately sealed to maintain the integrity of the flood barrier, the NRC said."
