Abstract

The uncertainty on transition temperature shift data of irradiated pressure vessel steels is relatively important (o = 22°C). 70% of this uncertainty is explained by error during Charpy testing (10%), error on copper content (20%) error on irradiation temperature (20%) and fluence (20%). Improving the measurement techniques of copper content, irradiation temperature and fluence respectively by a factor 2 ; 2 and 3 implies that the major causes of uncertainty would in this case be the Charpy technique.
