When an excess pressure and temperature are added to a containment vessel (CV) of a nuclear power plant (NPP) by a severe accident, overpressure damage of the CV is assumed to be possible. When the CV falls into such a situation, radioactive materials in the CV are released into the environment. Filtered containment venting systems (FCVS) that is installed in the exhaust systems reduce pressure in the CV while mitigating the release of the radioactive materials by the multi-scrubbers (venturi-scrubber, wet ...
