Technical aspects of designing a spacecraft for transporting radioactive waste

The topic of research is relevant due to the lack of intensive design studies of advanced nuclear waste spacecrafts when the nuclear waste is the primary source of energy. This paper deals with the problem of nuclear waste disposal in outer space. To find an optimal solution to this problem, it is necessary to discuss engineering aspects of nuclear waste spacecraft design. An approach to designing a spacecraft for transporting nuclear waste in outer space is presented. It implies the development of a new system of multi-level design of a nuclear waste spacecraft, which comprises external design, developing spacecraft configuration, interior design, and solving technical problems. The developed multi-level design system makes it possible to investigate the technical configuration of the nuclear waste spacecraft and its individual units taking into account operation modes, acting loads, materials used, etc. This system is supplemented by a united electronic model that combines the internal and external designs with due regard for the operation modes of its units. It allows us to formulate requirements for the electric propulsion, its design arrangement, mass and dimensional characteristics, and thermal state of its components and devices. The results of research will be useful in the design of future spacecrafts with powerful propulsion systems based on nuclear power plants and nuclear waste apparatus.
