EFFECT OF CREEP STRAIN INDUCED BY THERMAL AND RADIATION IMPACT ON STRESS-STRAIN CONDITION OF BODIES WITH CYLINDRICAL GEOMETRY
Abstract
The paper considers peculiar features of stress-strain condition of nuclear reactor active zone elements which are under an influence of high temperature and neutron irradiation with due account of thermal and radiation creepage taking jackets of heat releasing elements in the form of hollow thick-walled cylinder as an example. The numerical results of stresses and deformations which have been obtained with the account of creep strain and without it are presented in the paper.
