Thermal annealing as a method to predict results of high temperature
irradiation embrittlement
In order to assess the validity of post-irradiation annealing as a method to predict results of high temperature
irradiation a new analysis of experimental data has been performed revealing the combined influence
of annealing temperature and impurities content on residual embrittlement after annealing. For
2CrMoV (WWER-440 reactor pressure vessel) steel with low contents of copper and phosphorus, the
comparison of two embrittlement dependencies has been done: on irradiation temperature and postirradiation
annealing temperature. It is demonstrated that data for both the transition temperature shift
after irradiation, DTk, and the residual transition temperature shift after post-irradiation annealing, DTres,
fall within the same scatter band. A similarly close correlation is observed by comparison of yield
strength increases after irradiation and after post-irradiation annealing.
