A recent U.S. Nuclear Regulatory Commission report noted that safety-related structural welds at the Savannah River site’s Mixed-Oxide Fuel Fabrication Facility, or MOX, failed to meet industry specifications, according to The Augusta Chronicle. Structural weld supports for a section of the $7.7-billion project, called the Ground and Sorted Pellet Storage Unit Glovebox, were reported to be 4⁄16 in. in size, or 1⁄16 in. smaller than the American Welding Society requires for safety-related structural steel that measures more than three-quarters of an inch thick. NRC classified the welding problem as a Level 4 violation, the lowest possible.
