Large-scale Experiments on Core Degradation, Melt Retention and Coolability (LACOMERA)

Project ID: FIR1-CT-2002-40157
Funded under: FP5-EAECTP C


The LACOMERA project [1-5] at Forschungszentrum Karlsruhe (FZK) was a TALI action which started in September 2002 and had a duration of four years. The overall objective of the project was to offer research institutions from the EU Member States (except Germany) and Associated States access to four large-scale experimental facilities (QUENCH, LIVE, DISCO, and COMET) which could be used to investigate core-melt scenarios from the beginning of core degradation to melt formation and relocation in the vessel, possible melt dispersion to the reactor cavity, and finally corium concrete interaction and corium coolability in the reactor cavity.
The use of these experimental facilities was a remarkable option with high value. The project brought interested partners of different European Member States together in the area of severe accident analysis and control, with the goal of increasing public confidence in the use of nuclear energy. Moreover, partners from the newly Associated States were included as far as possible. Therefore, the needs of Eastern, as well as Western, reactors were considered in the LACOMERA project. The project offered a unique opportunity to get involved in the networks and activities supporting VVER safety and for Eastern experts to get access to large-scale experimental facilities in a Western research organisation to improve understanding of material properties and core behaviour under severe accident conditions.
