Between 2010 and 2015 the American Society of Testing and Materials (ASTM) developed a new embrittlement trend curve (ETC) to represent trends in a large international collection of reactor pressure vessel (RPV) surveillance data. This work was concluded in 2015 and resulted in an update to the ASTM Standard E900. In this paper we explore options for using an E900-15 style fitting function to represent trends in surveillance data collected from Japanese nuclear power plants....

Options for Using an ASTM E900-15-Style Function to Represent Trend in Domestic RPV Surveillance Data

Irradiation embrittlment prediction of Japanese surveillance data and MTR irradiation data was performed by using five different embrittlement trend curves, RG.1.99R2, ENOY, E900-15, EDF2010 and JEAC4201-2007[2013 addendum] (JEAC4201-2013). The comparison result showed that the prediction by JEAC 4201-2013 brought more appropriate prediction results than those by the other curves....
