Introduction of filtered containment venting system experimental facility in KAERI and results of aerosol test

Highlights: • Korean type FCVS integration test facility was introduced. • Aerosol removal test was conducted and evaluate the FCVS performance with DF. • Aerosol properties were analyzed at the inlet and outlet of the FCVS. - Abstract: Filtered containment venting system (FCVS) has been developed since 2014 in Korea, and an integration performance verification test has been performed at the Korea Atomic Energy Research Institute (KAERI). The experimental facility was named ARIEL: Aerosol Removal & Iodine Elimination (ARIEL). The ARIEL facility is composed of four major parts; venturi scrubber, cyclone, metal fiber filter (MFF), and molecular sieve (MS). In addition, a generation and sampling system of aerosol and iodine were equipped to the system. In this study, the current status of the FCVS experimental facility in KAERI is introduced along with a description of the aerosol generation and sampling system. Aerosol removal test results, performed 7 bar abs. with non-condensable gas, is also presented. The analysis of the results was conducted with filter and aerosol measurement equipment, and is included in the study.
