Abstract

The re-irradiated (IAI1) material condition data of a VVER-440 weld, which is part of the contribution of Fortum Nuclear Services Ltd. to the IAEA research programme, are given in summary. The data were created with the lower half of the Loviisa NPP re-irradiation chain 12K3 using specimen reconstitution. The second re-irradiation fluence will be created with the upper half of the same chain later on. The tests include tensile tests, ISO Charpy-V impact tests, Charpy-V impact tests of 5 mm x 5 mm and 3 mm x 4 mm cross-sectional specimens and fracture toughness tests of 10 mm x 10 mm and 5 mm x 5 mm cross-sectional specimens. The baseline, I and IA-condition data have been reported earlier. The joint analyses of the test results including earlier Loviisa data as well as a short comparison to an irradiation in Halden are given.
