An unknown amount of radioactive water was released accidentally into the Mississippi River late last week at the Grand Gulf Nuclear Station......An alarm apparently alerted workers to the presence of tritium, a byproduct of the nuclear reactor processes. The pumps were turned off stopping the flow.

Not only is there a record flooding along many parts of the Mississippi River in Missouri, Illinois and Tennessee, there is an additional concern of dealing with a radiation release into the mighty Mississippi - specifically tritium (the radioactive isotope of hydrogen). The Grand Gulf Nuclear Station is responsible for the release.
