Structural margin improvements in aged-embrittled RPV with load history effects

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.
