Experimental investigations into core degradation of LWR type reactors in serious accidents (LACOMERA project)

The project LACOMERA under the aegis of the Karlsruhe Nuclear Research Center (FZK, Germany) is considered. Experimental verification of accident versions of the LWR reactor core (RC) degradation including formation of corium, oxidation of cans of fuel assemblies during the contact with the air, decomposition of concretes are included in the project. Decision about the priority of experiments connected with penetration of the air in RC of the reactor that allowed verification of the oxidation of cans of fuel assemblies and other structural materials during their contact with hydrogen-vapor mixtures was accepted in the process of discussion of the project with taking part of international experts
