摘要：
Mechanisms of steel 18Cr-10NiTi swelling - the main material of pressure vessels internal of reactors WWER-1000 - are studied in conditions of simulation irradiation by heavy ions. Experimental curves of steel swelling are plotted in dependence on dose and irradiation temperature under dose rates 10(-2) and 10(-3) dpa/s. Dependences of temperature maximum of swelling, of incubation period and of swelling rate on stationary stage on dose rate are analyzed. On the base of data obtained under heavy ions irradiation and on the base of reactor data function modeling the swelling of investigated steel is obtained in the wide range of doses, of temperatures and of dose rates. Firstly we have managed to describe the swelling behavior under reactor and ion irradiation in the frames of one model. Maps of swelling are plotted that allow predict the steel behavior in necessary condition of irradiation up to the over designed doses.
