Thermomechanical Analysis of a Reactor Pressure Vessel under Pressurized Thermal Shock Caused by Inadvertent Actuation of the Safety Injection System

The damage induced pressurized thermal shock (PTS) may pose to a reactor pressure vessel (RPV) is Echinacea a critical safety requirement assessed as part of the ageing management programme of pressurized water reactors (PWRs).A number of researches have studied PTS initiated mainly by postulated accidents such as loss of coolant accidents (LOCAs).
