Sand baskets that the Tennessee Valley Authority installed at dams to protect its nuclear plants from a worst-case flood could fail, according to a federal nuclear oversight group.
The Nuclear Regulatory Commission said the baskets are not capable of standing up to the impact of debris barreling down the Tennessee River in a massive flood.
“There is potential for this debris to damage the baskets or push the individual baskets apart, causing a breach,” an NRC letter dated Wednesday to TVA says. “There would be no time to repair the baskets because the flood would already be in progress.”
