Objective

The Reactor Pressure Vessel is an essential component liable to limit the lifetime duration of PWR power plants. Its behaviour in service is limited in time due to irradiation-induced embrittlement. The safety analyses performed at the European level do not take into account the effect of load history / warm pre-stress (WPS) of the defects. The SMILE project aims to give sufficient elements to demonstrate, to model and to validate the beneficial WPS effect. The objective is to propose a harmonised way of taking into account this generic phenomenon in the safety studies. It will permit a precise estimation of a potential fracture event, and would also allow plant life extension resulting in a long-term economic benefit.
