RADIOACTIVE WASTE MANAGEMENT DURING DECOMMISSIONING OF RESEARCH BUILDING “B” AT JSC “VNIINM” SITE

The paper focuses on the radioactive waste management system that has been put in place to support the decommissioning of building “B”. Based on the diversification of financial sources for decommissioning, their breakdown by contract implementation timeline, three organizational and engineering flowcharts for the transfer of radioactive waste to a specialized organization were set. The paper presents operational flowchart for the radioactive waste treatment unit located in the building “B”, as well as the list of equipment involved in its operation. The basic equipment involved is as follows: equipment for RW compaction and decontamination, equipment for local gas cleaning systems, industrial vacuum cleaners, logistics support equipment (freight elevators, platforms, loaders), equipment for RW characterization CANBERRA Inspector-2000, as well as transport packages used to ship the waste to specialized organizations (Krad-3.0, KMZ, KMZ-RADON, PU-2EС-SH, PU-2EС-ST), soft packages of “big-bag” type. A total of 22 771.5 tons of waste were generated during the decommissioning. Radioactive waste amounted only to some 3.4 % of the total amount of waste. The costs associated with the transfer of radioactive waste to specialized organizations accounted for some 32 % of the actual project budget. ...

Keywords: radioactive waste, decommissioning, radioactive contaminated equipment, decontamination, compaction, specific activity.
