Analisis Desain Konseptual Sistem Pendingin Pasif Pasca Shutdown Reaktor PCMSR

One of the most important components in the design of 4th generation nuclear reactors is the development of cooling devices that are able to naturally circulate (natural circulation). In this research, numerical analysis has been carried out to get the heat exchanger size that still meets the natural circulation criteria. Analysis was carried out on the conceptual design of the passive cooling system after shutdown from the PCMSR reactor. The results showed that the size obtained was able to meet the natural circulation criteria without the need for additional components (chimney).
