The Wall Street Journal reports that due to past violations involving flood protections and automatic shutdown systems, the U.S. Nuclear Regulatory Commission (NRC) will keep Fort Calhoun nuclear power plant in Nebraska on a close-watch list. Most of the plant is under two feet of flood waters on the historically flooded Missouri River. There is currently about a ten foot safety margin between the flood waters and what the nuclear power plant is prepared to withstand -- but only because NRC busted them for their inadequate preparations late last year. "They are receiving heightened oversight because of inadequate procedures to protect their intake structure and auxiliary building from a flood...and other past performance issues," NRC spokesman Victor Dricks said.
