- Abstract
- The longtime durability of the multilayer shell of the container for radioactive waste storing can be increased at the expense of use of with the temperature autocoupling effect in. The possibility of the decrease of the most dangerous tensile stresses on the internal surface of the internal layer (polymer concrete) is shown. Herewith the mechanical stability of the external layer (glass reinforced plastic) is realized under the internal pressure up to 12 MPa and the 90°C temperature gradient. The cuts in the cylinder shell increase the compliance and durability of the construction and the elastic deformations energy, which is taken as the durability criterion for construction optimization.
