Workers moving barrels of radioactive waste at the site noticed one of the containers leaking about 13 gallons of liquid plutonium.

The area was immediately evacuated. But, according to a report released last week, it was more than 24 hours before cleanup started.

The report from the Defense Nuclear Facilities Safety Board says the contamination was so severe that cleanup crews had to leave because their safety equipment wasn’t adequate.

A spokesperson for the site’s operator Savannah River Nuclear Solutions says it’s common to re-examine safety procedures after such an event.

According to SRNS no one was hurt and the area has been contained.
