Development of Integrated Analysis Tool for Filtered-Containment Venting System

Abstract

A filtered containment venting system (FCVS) reduces containment pressure and amount of the radioactive release to the environment during a severe accident of nuclear power plant. CRIEPI has developed a FCVS analysis tool which evaluate removal performance of aerosol, iodine and organic iodine in each process of FCVS as decontamination factor as a function of the FCVS system parameters. The paper addresses the integrated analysis tool of FCVS simulator based on the experimental database.
