SPECIAL FEATURES OF HANDLING NON-DEFUELED K-27 NUCLEAR SUBMARINE DUMPED IN THE ARCTIC FOLLOWING ITS PROSPECTIVE LIFTING

Efforts focused on accelerated development of the Russian Arctic involve the implementation of measures aimed at bringing dumped and sunken nuclear- and radiation-hazardous facilities to a safe state. If the decision about lifting and disposal of some of them is made, the use of industrial infrastructure and various special equipment will be required, depending on the facility type and the chosen handling option. Using as an example the nuclear submarine K-27 that requires lifting for many reasons, the authors primarily consider special features of handling such objects after their lifting. Various options for the NS K-27 dismantlement and the management of its spent nuclear fuel and radioactive waste are addressed. Specific operations to be carried out are detailed, the outline and availability of the necessary infrastructure and special equipment are analyzed, and the need for additional equipment that is not currently available is identified.
