DECOMMISSIONING RADIOACTIVE WASTE STORAGE FACILITIES FSUE ROSRAO’S MURMANSK DEPARTMENT BRANCH IN THE NORTH-WESTERN TERRITORIAL DISTRICT

The article discusses one of today’s challenges, namely, the decommissioning of nuclear power facilities. It summarizes the experience in the decommissioning of radioactive waste storage facilities belonging to RosRAO’s Murmansk department branch of the Northwest Territorial District providing detailed overview of pre-decommissioning activities, as well as the decommissioning operations themselves, relevant technology and technical equipment applied. Pre-decommissioning stage involved large-scale efforts (2011—2015) on accumulated RW identifi cation and its inventory taking, as well as a comprehensive engineering radiation survey. Decommissioning projects have been developed and approved, a state environmental examination has been carried out with a Sanitary and Epidemiological Statement on compliance with state sanitary and epidemiological rules and regulations issued by FMBA of Russia. The paper presents the practice of constructing some engineering structures to provide additional safety and security of RW storage facilities during their dismantlement. Particular attention was paid to the problems associated with the use of special equipment.
