A filtered containment venting system (FCVS) reduces containment pressure and the radioactive release into the environment during a severe nuclear power plant accident. The FCVS removes radioactive materials via various process and these performance varies from moment to moment. CRIEPI has developed a FCVS simulator which evaluate aerosol, iodine and organic iodine removal performance by the FCVS (decontamination factor: DF) and the FCVS system behavior.
