Advancement of Filtered Containment Venting System (FCVS) by Silver Zeolite

(22) Verification test results of high temperature tests

Abstract

"Advanced radioactive material removal system using silver zeolite" aimed at developing an advanced Filtered Containment Venting System or “FCVS” has been qualified for the Ministry of Economy, Trade and Industry's 2020-2023 "Nuclear Industry Infrastructure Strengthening Project". Based on the advanced FCVS technology, such as a high performance scrubbing nozzle and a multi-layer metal fiber filter, and a silver zeolite filter to remove organic iodine. To install an advanced FCVS in nuclear power plants, a test device simulating the FCVS using high-temperature steam was manufactured. The equipment is branched into two systems; the normal pressure system and the high-pressure system. We will give an overview of these devices. In addition, we report the results of the Methyl Iodide adsorption performance test.We get the result of decontamination factor (DF) >780 with normal pressure system and DF>800 withthe high-pressure system.
