Washington River Protection Solutions has transferred the last of its legacy nuclear materials subject to accountability requirements from the Hanford 222-S Laboratory to waste burial grounds and to the 300 Area.
It completed a two-year effort to characterize, package and transfer 25 items from the lab that required higher security than the waste samples the lab currently handles. They included small samples and standards used to calibrate equipment.
"They were no longer needed and were costing us money to store and account for," said WRPS spokesman John Britton. Transfer of the items eliminates the need for security in the area, daily and bimonthly surveillance, and special inventories associated with emergency or abnormal conditions.
The material had been stored at the lab for several decades. WRPS worked with Mission Support Alliance safeguards and security personnel on the project as shipments were made from the lab.
