WANO Technical Support Mission on “RAW Management, Radiation Safety” started its work at the Chernobyl NPP on September 12. The main objective of the Mission – sharing experience in using techniques and procedures for sampling and characterization of solid RAW up to their conditioning/ immobilization, and receiving recommendations on sampling and laboratory studies of solid RAW.
Urgency of such topic of the Mission is determined by activities on the commissioning of Industrial Complex for Solid Radioactive Waste Management (ICSRM) at the SSE ChNPP. Today the ICSRM commissioning activities are to a wide extent complicated by duration of waste characterization at the process radiation monitoring system. This commissioning stage provides for management of non-uniform streams of radioactive waste retrieved from a “light” compartment of a solid waste storage facility with unknown radiation and physical parameters, their characterization and preparation of packages meeting the disposal criteria.
