105 K West Reactor and support structures – September 19, 2019
105 K East Reactor Building ready for construction of the secure safe enclosure
The U.S. Department of Energy and contractor CH2M HILL Plateau Remediation Company manage the deactivation, remediation, and eventual interim safe storage of the last reactors in the 100 Area.
The 100 K Area fuel storage basins (K Basins) were built in the early 1950s to receive and provide temporary storage for irradiated fuel from the K East and K West production reactors, which was awaiting shipment to other processing facilities at the Hanford Site. The K West and K East reactors were shut down in 1970 and 1971, respectively, and the K Basins were taken out of service. During the mid-1970s and early 1980s, the 105 K East and K West spent fuel storage basins were modified to provide temporary storage of N Reactor fuel. Since the 1990s, the N Reactor fuel has been removed from both reactors. The 105 K East reactors fuel storage basin has been deactivated, dewatered, and demolished, along with its support structures. In 2019, CH2M HILL Plateau Remediation Company successfully removed sludge from the 105 K West fuel storage basin to support the deactivation efforts.
Seventy-five waste sites and 49 buildings have been completed so far, with 43 waste sites and 32 buildings left to go.
- Deactivate, dewater, and demolish the 105 K West fuel storage basin to support the building of the secure safe enclosure around the 105 K West Reactor building
