Investigation of thermal state effect on mechnical characteristics of a capsule for space disposal of radioactive wastes

To transport radioactive wastes (RW) by a spacecraft (SC) to a disposal orbit, there is a need for a capsule to store the wastes on board. The capsule should be leak-tight and have good rigidity characteristics to prevent its destruction by various force factors affecting its casing both when put into orbit and during independent flight when being hit by meteorite. However, the strength properties of the capsule material will largely depend on the temperature of the working substance. The paper considers the problem of thermomechanical loading of the capsule, the solution has been obtained by finite element analysis and analytically.
