Figure II. September I, 1981, Stepovoy Inlet (Novaya Zemlya): Sinking of a damaged NS with two liquid metal 

 reactors. Depth about 20 meters. 



An urgent task is the organization of reliable monitoring (observation, tracking and analysis) 

 of the release of radionuclides from dumped SRW. 



Since all dumpings of SRW in northern seas (and most dumpings in far eastern seas) were 

 made in gross violation of international standards, and considering their potential radioecological 

 hazard, the only reliable solution to the problem can be to raise large high-level SRW from shal- 

 low disposal sites and reinter it in specially equipped repositories on land. However, this solution 

 must be adopted after comprehensive studies to assess the radiation risk of such SRW dumpings. 



3.4. Accident on a Nuclear Submarine in Chazhma Bay (Maritime Territory), 1985 



On August 10, 198S, during completion of reactor refueling work on an NS at a pier in a Na- 

 val shipyard in Maritime Territory (Chazhma Bay, town of Shkotovo-22), due to violation of nu- 

 clear safety requirements and reactor lid raising technology, an uncontrolled spontaneous uranium 

 fission chain reaction occurred in the port reactor. 



The resulting thermal explosion of the reactor destroyed the forward and aft machine rooms
