ASSESSMENT OF RADIONUCLIDE RELEASE INTO THE ENVIRONMENT IN RESULT OF POTENTIAL EMERGENCY IN COURSE OF LIFTING AND TRANSPORTATION OF THE DUMPED NUCLEAR SUBMARINE "K-27"
Accelerated development of the Arctic region of Russia increases requirements to environmental protection of sea water areas and adjacent territories. One of the acute important challenges is elimination of potential threats related to the nuclear and radiation hazardous objects dumped in this region. Safe implementation of the required activities requires risk assessment for all technological operations. Possible emergency situations are considered, including ignition of spontaneous chair reaction (SCR) in course of lifting and transportation of the dumped nuclear submarine (NS) “K-27”. Radionuclide release to the environment for the maximum emergency are estimated on the base of available assessment of the residual activity content of the “K-27” cores. The obtained results might be used as input data for assessing the impact of the potential emergency on the population, personnel, and the environment, and for the choice of variants for further treatment of the dumped NS and development of the relevant design documentation.
