    The Steam Generator Tube Rupture (SGTR) scenarios project was carried out in the framework of the research and training programme, EURATOM, in the field of nuclear energy during years 2000-2002. The first objective of the project was to generate a comprehensive database on fission product retention in a steam generator. The second objective was to verify and develop predictive models to support accident management interventions in steam generator tube rupture sequences, which either directly lead to severe accident conditions or are induced by other sequences leading to severe accidents. One challenge was to develop a model for the mechanical resuspension that could be included in the severe accident codes. In addition, it was shown that the existing models for turbulent deposition, which is the dominating deposition mechanism in dry conditions and at high flow rates, contains large uncertainties. The results of the project are applicable to various pressurised water reactors, including vertical steam generators (western PWRs) and horizontal steam generators (VVERs).
