Orano completed decommissioning and dismantling activities on the CP-5 reactor at the Argonne National Laboratory, which involved removing the remaining equipment from the CP-5 Large Scale Demonstration Project and culminated in unrestricted release of the facility. The scope of work included radiological characterization; demolition of the bio-shed and supporting structures, including pumps, ventilation systems, tanks, valves, filters, polar cranes, and bridge cranes; hot cell demolition; asbestos removal; and decontamination throughout the facility. Orano handled and packaged hazardous, mixed, and low-level waste, including materials with dose rates exceeding 250 R/hr. Orano also performed large-cask loading, handling, and decontamination. Orano personnel worked over 60,000 hours on this project without a lost time or recordable incident. The project was completed within the contractual completion date.

Contaminated Soil Sorting Unit

Orano developed a Contaminated Soil Sorting Unit (CSSU) to treat soil with different characteristics as a process for sorting out foreign material intermingled in soil. Decontamination bulk bags containing radioactive soils from decontamination work with activity over 8,000 Bq/kg were selected from a temporary storage area and classified into three categories based on their surface dose rates measured by the simple measurement method. The soils contained in the bags of each section were then sorted using a system combining a roll screen system and the CSSU system, and the share of soils with lower activity that can be separated was studied. The share of volume reduction of contaminated soil as a result of the removal of foreign material through roll system was also studied.
