The Stresa database: A token for the future

The experimental data recorded in Integral Effect Test Facilities (ITFs) are traditionally used in order to validate Best Estimate (BE) system codes and to investigate the behaviour of Nuclear Power Plants (NPP) under accident scenarios. In the same way, facilities dedicated to specific thermal-hydraulic Severe Accident (SA) phenomena are used for the development and improvement of specific analytical models and codes used in the SA analysis for Light Water Reactors (LWR). The Joint Research Centre (JRC), Ispra site, of the European Commission (EC) carried out important projects since the 70’s for the production of reactor safety experimental data. The LOBI was a reactor thermalhydraulic safety research programme (1970-1994) that produced a lot of ITF experimental data for a range of PWR operational and accident conditions. In the area of SA, the FARO, KROTOS facilities (1991-2000) simulated Melt Fuel Coolant Interaction (MFCI) phenomena, considering either in-vessel (quenching) and ex-vessel (spreading) experiments and potential situations for steam explosions. The STORM facility simulated experiments in the area of Aerosol Transport. Experimental data mentioned above were stored in the STRESA (Storage of Thermal REactor Safety Analysis Data) database developed by the JRC Ispra site. At present the JRC STRESA database is hosted and maintained by JRC Petten site. The paper presents these past activities on the production of experimental data and its storage in the JRC STRESA database in order to further disseminate, promote the usage of the database containing these data and to demonstrate long-term importance of well maintained experimental databases.
