Preliminary Notice of Violation issued to the University of California related to Criticality Safety and the Quality Assurance Program at the Lawrence Livermore National Laboratory, July 28, 1998 (EA-98-06)
This letter refers to the Department of Energy's (DOE) evaluation of the facts and circumstances surrounding a series of criticality safety infractions occurring between May and December 1997 in [a building] at the Lawrence Livermore National Laboratory (LLNL). [The building] is the central repository used to process and store [radioactive material]. During the period May 20 through July 15, 1997, Certified [Radioactive Material] Handlers violated criticality safety procedures for mass limits and form controls 12 times. Subsequent to these violations, the operations at [the building] were curtailed by LLNL, but [radioactive material] movements that were still allowed resulted in additional violations of criticality safety procedures. In October 1997, [radioactive material] parts were received at the [ ] storage vaults, [building], and placed into storage in a vault location which violated the mass limits, criticality safety controls for the vaults. A subsequent review by your staff of vault storage compliance to criticality safety controls identified an additional ten criticality safety control infractions in the vaults. Finally, in December 1997 during a limited operation to repackage and ship [radioactive material], a criticality safety control was violated when [radioactive material] was removed from a sealed metal container.
