FITNESS FOR DUTY REPORT INVOLVING A NON-LICENSED EMPLOYEE SUPERVISOR

A non-licensed employee supervisor had a confirmed positive drug test during random testing. The employee’s access to the plant has been terminated. Contact the Headquarters Operations Officer for additional details.

The licensee informed the NRC Resident Inspector.

Grand Gulf nuclear power station is a General Electric boiling water reactor. It lies on a 2,100 acres (8.5 km2) site near Port Gibson, Mississippi. The site is wooded and contains two lakes. The plant has a 520-foot (158 m) cooling tower.
Grand Gulf is operated by Entergy Nuclear and owned jointly by System Energy Resources, Inc. (90%) and by South Mississippi Electric Power Association (10%).

After heavy rains in late April, 2011, workers were pumping standing water that had collected in the abandoned, never-completed Unit 2 turbine building into the Mississippi River. Detectors sounded alarms at the presence of tritium in the water, and the pumping was stopped, and the accidental release was reported to the Mississippi Health Department and to the NRC.

As of the dates of the news reports, it was unknown both how much tritium had entered the river, and how the tritium had collected in the standing water, given that Unit 2 was not an operational reactor, had never been completed.

It is unknown how much tritium entered the river, because samples were not taken at the time of the leak.

The NRC is investigating to find the source of the leak.
