Structural Margin Improvements in Age-embrittled RPVs with Load History Effects (SMILE), Final report, EUR 23317

Project ID: FIKS-CT-2001-00131
Funded under: FP5-EAECTP C


The SMILE project started in January 2002, as part of the Fifth Framework Programme of the European Atomic Energy Community (Euratom FP5), and is now achieved [1]. It aims at confirming on small- and large-scale specimens the beneficial effect of warm pre-stress (WPS) in RPV assessment leading to a significant improvement of the material resistance regarding the risk of brittle failure, and to model and validate this effect. It also aims at harmonising the different approaches to lay the basis for European codes and standards regarding the inclusion of WPS in RPV assessment regarding the risk of brittle failure.
Within the framework of the project, main experimental, analytical, and numerical results are now available. They are summarised in this report. Based on these results, some recommendations are proposed for the application and inclusion of WPS in RPV safety assessments.
