Reactor pressure vessel surveillance databases from other

Abstract This chapter describes the surveillance database of the Western pressurized water reactor (PWR) reactor pressure vessel (RPV) beltline materials obtained from US, French and Japanese nuclear power plants (NPPs) and those from other countries, together with an overview of the characteristics of PWR RPVs. Trends of surveillance data which will be obtained in the near future and the possibility of new data from reconstituted and miniature specimen techniques are presented.
