Stress and strain condition of thick-walled cylindrical and spherical containers for nuclear reactors under internal pressure and high temperature effect
The paper presents an original construction design of high pressure shells made of heavy fine-mesh wire-fabric reinforced concrete, as well as results of computing experiments carried out by means of the «ANSYS» simulation program with the purpose of evaluating the stress and strain condition under effect of internal pressure, and the joint effect of temperature and pressure. It is shown that in the spherical formed container subjected to the effect of high temperature and pressure, there is formed a more homogeneous stress and strain condition, which is an evidence of a higher reliability of the new construction design.
