Two-Dimensional Numerical Analysis of Irradiation Swelling in WWER-1000 Reactor Baffle with Variation of Input Data on Volumetric Heat Generation and Damaging Dose

  • Published:
Strength of Materials Aims and scope

The paper addresses the currently available mathematical models of irradiation swelling of austenitic steel 08Kh18N10T which is used for the manufacture of WWER-1000 reactor internals: the models of free swelling, which take into account temperature and damaging dose, and the model that includes a stress state. The irradiation creep phenomenon is taken into consideration too. The authors review the input data such as the volumetric heat generation, temperature, and damaging dose in a baffle and core barrel of WWER-1000 reactor; based on these data a two-dimension computational assessment of irradiation swelling of reactor internals has been performed and is followed by a comparative analysis of the results. The latter shows how the input data variation affects the calculated results. Evaluation of the baffle form change suggests that the baffle may have a contact interaction with the core barrel.
