Preservation and Use of Integral System Test Facilities Data: the Experience of the Lobi Data and the Stresa Database

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 accidental scenarios. The extent to which the existing reactor safety experimental databases are preserved was well known and frequently debated and questioned in the nuclear community. The Joint Research Centre (JRC) of the European Commission (EC) has been deeply involved during years in several projects for experimental data production and experimental data preservation; in particular a big initiative was the LOBI ITF project. In this context the STRESA (Storage of Thermal REactor Safety Analysis Data) web-based informatic platform was initially planned by JRC-Ispra with the main objective to disseminate documents and experimental data from large in-house JRC scientific projects, as LOBI ITF data, and later it was extensively used in order to provide a secure repository of ITF data exploiting modern computer information technologies for access and retrieve of the information. The paper is focused in presenting one of the largest EC initiatives on the production of ITF data (the LOBI project), its use for system thermalhydraulic code assessment and its storage in the JRC STRESA node web platform (http://stresa.jrc.ec.europa.eu/stresa/). The objective of the paper is to further disseminate and promote the usage of the database containing these LOBI ITF data and to demonstrate long-term importance of well maintained ITF databases. At present the JRC STRESA database is maintained by JRC-Petten.
