• The Reactor Pressure Vessel (RPV) is an essential component liable to limit the lifetime duration of PWR plants. The structural integrity assessment of defects in RPV subjected to PTS transients made at an European level generally doesn't take into account the potential beneficial effect of the load history (warm pre-stress WPS). A 3-year European Research & Development programme has been started in January 2002 as part of the Fifth Framework of the European Atomic Energy Community (EURATOM). The SMILE project ('Structural Margin Improvements in aged-embrittled RPV with Load history Effects') is one of a 'cluster' of Fifth Framework projects in the area of plant Life Management. It aims to give sufficient elements to demonstrate, to model and to validate the beneficial WPS effect in a RPV structural integrity assessment. Finally, this project aims to harmonize the different approaches in the European Codes and Standards regarding the inclusion of the WPS effect in the RPV structural integrity assessments. All elements necessary to propose a method to take into account this effect will be gathered or obtained. This will be done through experimentals works, leading to a deep understanding of metallurgical and mechanical phenomena, and through numerical works and development of models. The results will permit a much more precise prediction of possible brittle fracture in a RPV during a severe PTS transient. The present paper describes the aims and objectives of SMILE project, its interactions with NESC (Network for Evaluating Steel Components) and other European projects, and gives details of its various Work-Packages. Finally, the on going progress of the project is described.
