Nuke leak kept quiet

Nuke fuel plant 46 miles from Asheville has a leak, but nobody knows about it for three years.
Via Citizen-Times site this am where it is a rather well-read story:

A three-year veil of secrecy in the name of national security was used to keep the public in the dark about the handling of highly enriched uranium at a nuclear fuel processing plant — including a leak that could have caused a deadly, uncontrolled nuclear reaction.

The leak turned out to be one of nine violations or test failures since 2005 at privately owned Nuclear Fuel Services Inc., which operates a 65-acre gated complex in tiny Erwin, about 46 miles north of Asheville, and supplies fuel to the Navy’s nuclear fleet.

Later in the story:

Some 35 liters, or just more than 9 gallons, of highly enriched uranium solution leaked from a transfer line into a protected glovebox and spilled onto the floor. The leak was discovered when a supervisor saw a yellow liquid “running into a hallway” from under a door, according to one document.
