As Historic Flooding Grips Texas, Groups Demand Nuclear Plant Be Shut Down
As record-breaking rainfall and unprecedented flooding continue to batter the greater Houston area and along the Gulf coast on Tuesday, energy watchdogs groups are warning of “a credible threat of a severe accident” at two nuclear reactors still operating at full capacity in nearby Bay City, Texas.
Three groups—Beyond Nuclear, South Texas Association for Responsible Energy, and the SEED Coalition—are calling for the immediate shutdown of the South Texas Project (STP) which sits behind an embankment they say could be overwhelmed by the raging flood waters and torrential rains caused by Hurricane Harvey.
“With anticipated flooding of the Colorado River, the nuclear reactors should be shut down now to ensure safety.”
—Karen Hadden, SEED Coalition”Both the U.S. Nuclear Regulatory Commission and the STP operator have previously recognized a credible threat of a severe accident initiated by a breach of the embankment wall that surrounds the 7,000-acre reactor cooling water reservoir,” said Paul Gunter, director of the Beyond Nuclear’s Reactor Oversight Project, in a statement by the coalition on Tuesday.
The groups warn that as Harvey—which on Tuesday was declared the most intense rain event in U.S. history—continues to dump water on the area, a breach of the embankment wall surrounding the twin reactors would create “an external flood potentially impacting the electrical supply from the switchyard to the reactor safety systems.” In turn, the water has the potential to “cause high-energy electrical fires and other cascading events initiating a severe accident leading to core damage.” Even worse, they added, “any significant loss of cooling water inventory in the Main Cooling Reservoir would reduce cooling capacity to the still operating reactors that could result in a meltdown.”
With the nearby Colorado River already cresting at extremely high levels and flowing at 70 times the normal rate, Karen Hadden, director of SEED Coalition, warned that the continue rainfall might create flooding that could reach the reactors. “There is plenty of reserve capacity on our electric grid,” she said, “so we don’t have to run the reactors in order to keep the lights on. With anticipated flooding of the Colorado River, the nuclear reactors should be shut down now to ensure safety.”
