The assurance of safe and economic long-term operation of nuclear power plants in the context of material ageing is a key topic for both nuclear power industry and nuclear safety authorities. Pressure boundary components in the primary coolant circuit of light water reactors are made of low-alloy steels, stainless steels and Ni-base alloys and are very critical components with regard to safety and lifetime. Environmentally-assisted cracking (EAC) of structural materials in pressurized and boiling water reactors is one of the biggest challenges. An accurate knowledge on the system conditions which may lead to EAC initiation and growth is thus evidently indispensable to ensure the safe and economic long-term operation in this context. In the current lecture the state-of-the-art on EAC research on primary-circuit materials in high-temperature water will be presented and discussed.
