Nuclear plant workers release unknown amount of radioactive tritium into Mississippi River
Workers at the Grand Gulf Nuclear Plant in Port Gibson, Miss., last Thursday released a large amount of radioactive tritium directly into the Mississippi River, according to the US Nuclear Regulatory Commission (NRC), and experts are currently trying to sort out the situation.
