Overview
ABSTRACT
The stringent demands for safety, reliability, and durability that are intrinsic to the nuclear industry have motivated the choice of specific metallic materials. In this context, the current article details the main metallic materials used in the construction of pressurized water reactors (PWRs), including their development and recent technological advancements.
After presenting the general material requirements for nuclear reactor structural materials, the technical solutions developed to meet the specific needs of the PWR fleet, by considering various components of the primary and secondary circuits, are discussed. Emerging manufacturing processes for these components are also addressed.
