RICHLAND, Wash. – Crews at Hanford’s tank farms recently completed removal and staging of 52 large concrete covers used to shield hoses for transferring radioactive waste between waste tanks in Hanford’s AY and AP farms. Tank farms are groups of tanks. The covers are known as “barns.” They are being staged as part of a worker safety and infrastructure improvement project until they are used in construction of a hose system that will transfer waste from A Farm to AP Farm. As part of the Direct-Feed Low-Activity Waste approach, which is an EM 2020 priority, the AP Farm will feed pretreated waste to Hanford’s Waste Treatment and Immobilization Plant for vitrification.
