Fuel Conditioning Facility located next to the EBR-II. The clean-up process for EBR-II includes the removal and processing of the sodium coolant, cleaning of the EBR-II sodium systems, removal and passivating of other chemical hazards and placing the deactivated components and structure in a safe condition. Decommissioning The reactor was shutdown in September 1994. The initial phase of decommissioning activities, reactor de-fueling, was completed in December 1996. From 2000, the coolants were removed and processed. This was completed in March 2001. The third and final phase of the decommissioning activity was "the placement of the reactor and non-reactor systems in a radiological and industrially safe condition." Between 2012 and 2015, some components of the belowground reactor were removed. The cost for removal actions in the reactor building were about$25.7 million. The basement with the reactor was filled with grout. The three-year decontamination and entombment project costed $730 million. In a later stage, the large concrete dome that surrounds the EBR-II reactor would be removed and a concrete cap placed over the remaining structure. In 2018, the plans were changed. The removal of the dome was stopped and in 2019, a new floor was poured and the dome got a fresh paint to prepare the building for industrial use. The building will be used for a research facility on top of the entombed reactor. The dome is an integral part of the tomb along with a "Site-Wide Long-Term Management and Control Program". The use of the site will be industrial in nature for a 100-year period and likely in the indefinite future thereafter. Related facilities The objective of the EBR-II was to demonstrate the operation of a sodium-cooled fast reactor power plant with on-site reprocessing of metallic fuel. In order to meet this objective of on-site reprocessing, the EBR-II was part of a wider complex of facilities, consisting of Fuel Conditioning Facility: facility for reprocessing and treating spent fuel from the EBR-II and other reactors, using an electrorefiner for electrometallurgical treatment of spent fuel Fuel Manufacturing Facility: facility for the manufacturing of metallic fuel elements Hot Fuels Examination Facility: a "hot-cell" complex for handling and examining highly radioactive materials remotely Sodium Processing Facility: facility for processing of reactive sodium into low-level waste Integral Fast Reactor The EBR-II has served as prototype of the Integral Fast Reactor (IFR), which was the intended successor to the EBR-II. The IFR program was started in
