Preliminary Studies on Thermal Cycling of Reactor Pressure Vessel Steel

Authors: Manoj Saini, Navneet Arora, Chandan Pandey, Husain Mehdi

The reactor pressure vessel (RVP) of a pressurized water reactor (PWR) or a boiling water reactor (BWR), i.e., of a light water reactor (LWR), is made of carbon steel. The inside surface is clad with stainless steel to prevent general corrosion. These pressure vessels are expected to with-stand normal and postulated accident conditions. These vessels are installed within a concrete biological shield and the whole plant is in turn surrounded by a concrete containment building. Most of the operating experience relates to two and three loop design. The scope of this paper is to study of mechanical behavior of SA 516 grade 65 carbon steel used for steam generator application undergoing thermal cycling loading. The effect of temperature, cycle time, pre stress and no of cycle would be the varying parameters
