Elka Anastasova


The SU “PRRAW Novi Khan” is surface type repository and it was constructed according to a modified Russian design in the early sixties.

According to the National Strategy for RAW&SNF management, the SU “PRRAW-Novi Han” will be decommissioned on stages after the 2022. The decommissioning will be done by retrieval of RAW and sealed sources from the disposals; treatment; conditioning and packing in new containers, in accordance with the acceptance criteria of the National Disposal Facility; dismantling of the underground facilities and remediation of the site.

During the preparatory stage it should be clearly defined the final status of the facility and the final destination of all generated waste, and should be selected technologies and provided all necessary tools and equipment for removal of RAW; dismantling of the facilities and treatment conditioning and packing of produced RAW.
