A frozen valve resulted in a water spill on the grounds of Entergy’s River Bend nuclear plant in St. Francisville, LA, Tuesday, but it did not pose a risk to public health.

A report filed with the Nuclear Regulatory Commission (NRC) and released Thursday said between 100 and 1,200 gallons leaked from the valve connected to a cooling tower blow-down line.

Upon discovering the leak, crews erected barriers to keep the water from reaching storm drains and confined the spill to plant grounds.

At the time the event ended up reported, workers reduced the leak to a small drip and repairs were underway.

The report said the water contained 4,584 pico-curies per liter of tritium, with no detectable gamma activity. By comparison, the EPA limit on tritium in drinking water is 20,000 picocuries per liter.

The low temperature in St. Francisville dropped to 19 degrees F on Tuesday when the valve broke.
