6419418_GA Chattanooga newspaper reports that radioactive water leaked from a tank at an Alabama nuclear plant, releasing tritium into the environment.  The report said that the leak occurred last week at the Browns Ferry Nuclear Power Plant near Athens, Alabama. A spokesman for the Tennessee Valley Authority, which operates the plant, said the leak was quickly contained and presented no public risk. The TVA said a drain line leaked 100 to 200 gallons of water containing tritium levels above acceptable drinking water standards. In a report to the Nuclear Regulatory Commission, the TVA said it increased monitoring of water around the plant but hasn’t detected elevated tritium levels outside the plant. Tritium is a radioactive form of hydrogen that occurs in nature and also as a byproduct of nuclear fission. WRCBtv.com
