An inspection has determined the likely cause of the hydrogen fluoride gas leak in the main processing building at the Y-12 National Security Complex in April.

A visual inspection found a hole in a calibration valve in a cylinder enclosure in Building 9212 on the west side of Y-12, the Defense Nuclear Facilities Safety Board said in an April 12 report. The hole is the likely source of the leak of anhydrous hydrogen fluoride, the DNFSB said.
