Basic aspects of the concept of reactor compartment (including damaged compartments) management during utilization of nuclear powered submarines -- High priority R and D
- Research and Development Inst. of Power Engineering, Moscow (Russian Federation)
Large-scale decommissioning of Russian nuclear-powered submarines (NPS) and their utilization prospects gave rise to numerous complicated scientific and technical, as well as economic, problems. Problems of handling of radioactive equipment from the reactor compartments (RC) are among the vital ones, arousing a growing concern with the public. Without solution of the problems the processes of NPS utilization can not be considered completed. It involves potential hazard, for the environment both from NPS being paid up (temporal on-float storage) with unloaded spent nuclear fuel (SNF), and RC, cut from submarine hull, containing highly radioactive equipment and materials but no SNF. Diverse variations of the concept of reactor compartment handling of NPS subject to, utilization are possible, but, in principle, there are essentially two variants: (1) RC utilization directly in the course of NPS utilization, envisaging removal of radioactive equipment from the reactor compartment and its cutting; (2) RC utilization after preliminary long-term storage of radioactive equipment of nuclear steam supply system (NSSS) in the standard sites within RC, when radioactivity of SGF equipment and materials as a result of natural decay of radionuclides is reduced to the values permitting RC cutting without employment of special means. When analyzing this or that variant of the concept, various factors are to be allowed for. First and foremost, the technology of RC handling is to provide: (1) minimum amount of radioactive wastes; (2) minimum radiation burden to the environment and personnel; (3) minimum material and financial expenditures; and (4) maximum radiation and ecological safety. RDIPE in cooperation with the leading enterprises of RF Minatom, Goskomoboronprom and Ministry of Defense has developed a concept of handling radioactive equipment in NPS reactor compartments, and its principle concepts are presented here.
