Sitting along the Hudson River near New York City, the Indian Point nuclear plant repeatedly attracted controversy during the decades it generated electricity. The latest flashpoint revolves around plans to release 1.3 million gallons of water with traces of radioactive tritium into the river as part of the plant's decommissioning. Supporters of the planned releases say they are just like those made when Indian Point was producing power and that the concentration of tritium has been far below federal standards.
