A design parameter study is presented for the closed-loop type passive containment cooling system(PCCS) which is equipped with two heat exchangers: one installed at the inside of the containment andthe other submerged in the water pool at the outside of the containment. A GOTHIC code model for PCCSperformance analyses was set up and the design parameters such as the heat exchanger sizes, locations,and water pool tank volumes were analyzed to investigate the feasibility of installing this type of PCCS inPWRs like OPR-1000 being operated in Korea. We identified the size of the circulation loop and heatexchangers as major design parameters affecting the performance of PCCS. The analyses showed that theheat exchangers in the inside of the containment would be more influential on the heat removalcapability of PCCS than that installed in the water pool at the outside of the containment. Hence, it wasrecommended to down-size the heat exchangers in the water pool to optimize PCCS without compromisingits performance. Based on the parametric study, it was demonstrated that a closed-loop type PCCScould be designed sufficiently compact for installation in the available space within the containment ofPWRs like OPR-1000.
