In order to develop the advanced filtered Containment Venting System (FCVS), we developed a low pressure drop scrubber nozzle, improved the decontamination coefficient by preventing waves in the scrubber pool, developed a safety relief valve to automatically start the FCVS, optimized the multilayer metal fiber system, and developed silver zeolite. Efforts were made to improve the decontamination coefficient by selectively using AgX and AgR, and to install xenon adsorption filters.
