4 barrels rupture at Idaho nuclear site via The Columbian

 

BOISE, Idaho (AP) — A total of four barrels containing radioactive sludge at an eastern Idaho nuclear site were found to have ruptured, officials said Wednesday, after initially saying earlier this month that one barrel was leaking.

Officials said there were no injuries and no threat to the public, and workers in protective gear have installed a closed-circuit video camera to monitor the situation.

Erik Simpson, a spokesman for U.S. Department of Energy contractor Fluor Idaho, said it appears all four 55-gallon barrels ruptured the same day they had been packed. An alarm on April 11 alerted officials that one barrel ruptured at the 890-square-mile federal site that includes the Idaho National Laboratory.

Simpson said three Idaho National Laboratory firefighters that entered the earthen-floored structure on April 11 to extinguish a smoldering barrel reported other possible breaches, and crews outside heard some of the barrels rupture.

A three-person crew last week entered the structure and confirmed the additional ruptures, Fluor Idaho said.

Simpson said the ruptured barrels contained material sent in other barrels to Idaho in the 1960s. He said those 1960s barrels likely contained fluids and solvents from nuclear weapons production at the Rocky Flats Plant near Denver. He said it’s possible the barrels might have originated elsewhere and been shipped to Denver before eventually being sent to Idaho.

The barrels were initially buried in unlined pits in Idaho, but were unearthed as part of a cleanup process at the site. Simpson said a high-tech examination of the unopened barrels found they had unopened containers, and were moved to the earthen-floor structure that’s 380 feet long and 165 feet wide.

He said the barrels were emptied, the contents examined, and then repackaged in new barrels on April 11. At least one and possibly all of those newly packed barrels ruptured later that same day, he said.
