Corresponding geometry and finite element models were developed in accordance with design documents and passports of the baffle and cavity of the internals during performance of the second stage of work on the project in correspondence with the conclusions of the first stage on relevance of application of the finite element method in combination with the current models of radiation creep of material for determination of stress-strain state of the internals elements of WWER-1000 reactor. Based on current models of radiation swelling and radiation creep of internals material (austenite steel 08Kh18N10T) and in combination with the finite element method, the procedure and calculation algorithms were developed for determination of kinetics of internals stress-strain state in process of operation taking into account existing inhomogeneities of a temperature field and speed of accumulation of a damaging dose in the internals elements as well as operating pressure and weight of the elements themselves.
