| Event Description | On May 12, 2014, at 1458 CDT, River Bend Station management determined that tritium confirmed to be present in water samples taken from in-leakage into the below-ground elevation of the turbine building basement, through an underground pipe penetration, was reportable in accordance with NEI 07-07, Ground Water Protection Initiative. The leakage was tested for gamma and tritium activity. No gamma contamination was detected. Tritium was measured at 28,270 picocuries per liter. The source and volume of the radioactive in-leakage is unknown.
The leakage into the plant is currently being contained, and actions are in progress to identify the source.
