Effect of tensile and compressive stresses on the radiation swelling, microstructure, and creep strain in austenitic steel Kh18N10T is considered. The gas-filled samples of a complex shape prepared from steel Kh18N10T were irradiated in a BOR-60 reactor for 2 years to a damaging dose of 15 dpa at a temperature of 420–450°C. In the shells of the irradiated samples, compressive and tensile stresses were created. Samples were also irradiated, in which these stresses practically were absent.
