The Associated Press reported a few minutes ago:
PORT GIBSON, Miss. (AP) – Federal safety inspections are at the Grand Gulf Nuclear Power Plant in Claiborne County after the accidental release of radioactive water in late April into the Mississippi River.
Lara Uselding, public affairs officer with the NRC Region IV office in Arlington, Texas, says Monday that the agency has not determined how much tritium was released. However, she says there was no danger to the public because the tritium would have been diluted by the river.
Although naturally occurring, tritium is also a byproduct of nuclear power operations. Long-term exposure to high amounts can increase a person’s cancer risk.
Entergy Nuclear, which operates Grand Gulf, filed a report with the NRC.
