Project summaryNowadays there are many decommissioned Nuclear Powered Submarines at the Shiprepair and Shipbuilding Yards of Primorie. Every year more and more Submarines are inactivated.
The experience of the enterprises of RosSudoStroyenie showed that NPS dismantling process was the complicated technological procedure. A considerable volume of harmful industrial waste including SNF and RW is generated under the execution of this process. The most important and timely task is to consider all harmful factors of the industrial complex, to estimate the degree of their environment effects and to develop NPS dismantling procedures, special design and technological plans of the interim (25 years) and long-term (100 years) storage of the reactor compartments (damaged included) and recommendations concerning environment safety in Primorie.
The object of the Project is the investigation of environment effects of NPS (damaged ones included) dismantling and the development of proposals concerning the choice of the optimal plan and procedure of NPS dismantling, the improvement of RW and SNF management plan and the ecological safety in Primorie.
The Project will be carried out by “weapon” specialists of the Russian leading research institutes and enterprises engaged in challenges of Submarines dismantling: ”Onega”, RSC “KI”, IGEM RAS, IBRAE RAS, Krylov Institute, Kolsky Institute with involvement of some Russian institutions having great experience in NPS dismantling and environment protection.
Tasks of the described Project are primarily as follows:
- the determination of real and probable sources of radiation and chemical contamination in Primorsky Krai;
- the development of main NPS dismantling procedures including the choice of hull’s structures cutting, cable shredding, and electrical and radio electronic equipment disassembling;
- the development of SNF and RW management procedures;
- the development of different ways of sarcophagus design for damaged reactors disposal with taken safety conditions and labor input reduction into account;
- the development of the thorough technology for sarcophagus, preparation of damaged reactor compartments for loading into sarcophagus and transport, technological plans;
- the study of the mountain and geological conditions and nature characteristics of proposed long-term storage areas;
- the estimation of real and potential sources of radiation and chemical contamination of environment and population;
- the estimation of NPS dismantling operations effect upon environment, personnel, and population;
- the estimation of the radiation safety of reactor compartments long-term storage at special equipped sites (non-damaged Suds);
- the estimation of the environment safety of reactor compartments long-term storage using the special encapsulation technologies (damaged Submarines);
- the feasibility study of methods of decommissioned Submarines dismantling including technical and economic appraisal of environmental safety of reactor compartment storage site construction in Primorsky Krai, and the assessment of technical and economic criteria of sarcophagus construction;
- the retraining of “weapons” personnel.
By carrying out our works we’ll have been able:
- to train engineers in advanced SNF and RW management procedures and methods of the environment effects estimation;
- to offer safe technological and organizational decisions on harmful industrial waste management from the economical point of view.
