Abstract

The re-irradiation material studies aim to provide reliable data for the safety analyses of the annealed Loviisa unit 1 pressure vessel. A physical description for the material toughness evolution during re-irradiation should be developed and a clear classification and quantification among the variety of applied toughness parameters should be made. A quantitative re-irradiation model will be approached gradually within the boundary conditions set by the reproducibility of environmental parameters, availability of relevant materials and the required irradiation times. In the current paper data measured with Lo-1 surveillance weld and the simulated weld 501 is given and analysed.
