On December 13, 2019, an international conference on the project INS/2013 /MC.04/13 for nuclear legacy decommission was held in Moscow. The project is dedicated to feasibility study and preparation for the implementation of an Action Plan Concerning the Safe and Secure Management/Disposal of Sunken Radioactive Objects in the Arctic Sea.
The project was launched by Rosatom and the European Commission in 2016. SOGIN
company (Italian state company responsible for nuclear decommissioning as well as management and disposal of radioactive waste produced by industrial, research and medical processes) conducted the study under the contract awarded by European Commission. Other European companies with expertise in nuclear waste management were engaged in the study as well, including Energiewerke Nord
(German group of companies dealing with the decommissioning of nuclear facilities), Nuvia
(British company engaged in international nuclear management across the complete lifecycle) and the Norwegian Radiation and Nuclear Safety Authority, DSA
Experts conducted the assessment of 17,000 sunken objects by technical characteristics and geographical location. Six most dangerous objects were identified that contain nuclear material (spent nuclear fuel). These are nuclear submarines K159
, as well as reactor compartments of nuclear submarines K11, K19, K140
and of nuclear icebreaker Lenin
. These six objects contain more than 90% of the total activity of all sunken facilities.
