摘要
It was observed by LM Davies that 'Eastern' and 'Western' reactor pressure vessel steels have similar spans of irradiation sensitivity. In this paper the similarities and differences between these steels are explored by comparison between published data on VVER steels, and data and models developed on Western type welds with similar nickel contents to the VVER-440 and VVER-1000 steels. This comparison requires that allowance be made for irradiation temperature, dose rate and manganese effects. This can only be done approximately; even so, the results show encouraging similarities in behaviour between the Eastern and Western categories of steel. (C) 2004 Elsevier Ltd. All rights reserved.
