“…All SMART components herein were considered following the design features of both the steam generators and the pressurizer enclosed in the reactor pressure vessel, as shown in the left side of Figure 2 (original design) 19 . For the pool‐type concept development, the reactor pressure vessel was submerged in a water pool under a fixed ratio of water:air (ie, 70:30), as presented in the right side of Figure 2 (double‐containment design).…”

Summary In March 2015, the Kingdom of Saudi Arabia signed an agreement with South Korea to build the system‐integrated modular advanced reactor (SMART) originally developed by the Korean Atomic Energy Research Institute. The SMART is a structurally contained safe dual‐purpose power plant reactor that produces both electricity and desalination. This study aims to design a double‐containment structure with a pool‐type concept to enhance the SMART safety and develop a robust design for future modular reactors. For that purpose, a theoretical model is developed herein, which leads to the modeling of a double‐containment structural design of a water pool. The model calculates various parameters (ie, temperature, pressure, phasic velocities, and condensable gases) and is used to develop a simulation program for use in a computational assessment. Moreover, two best‐estimate thermal hydraulic engineering programs, namely THEATRe and RELAP5, are used to simulate the original SMART with the double‐containment water pool structure. The differences in the modeling strategies of the two simulation techniques are discussed to accurately measure various technical parameters. Accordingly, a nodalization diagram of the reactor and the pool‐type concept are developed and simulated. The results obtained from the computational models yield the error of >2%, depicting accuracy. A small‐break loss of coolant accident is also simulated to mitigate the transient conditions. The result verifies the adoptability of this reactor concept in any other small modular reactor.

NUMERICAL STUDY ON CONDENSATION IN IMMERSED CONTAINMENT SYSTEM OF ADVANCED SMR DURING UNCONTROLLED DEPRESSURIZATION.A number of Small Modular Reactor designs have been developed by several countries and mostly each comes with specific innovative improvements. One of them is NuScale reactor which implements a steel, small size immersed-in-pool containment system. This new approach derives new challenges as control for temperature and pressure inside the containment is conducted without any active system. Passive heat transfer and condensation is important parameter that needs to be investigated for this kind of containment design. Hence, this work examines the condensation, pressure and the effect of pool temperature on capability of the containment to remove heat and maintain integrity passively. The work is performed using numerical simulation by modeling the reactor in RELAP5 code. Calculation result shows that during depressurization, maximum pressure limit of 5.5 MPa is not exceeded. Besides, the containment design provides enough capability to transfer heat from the containment to water pool passively. This work also investigates sensitivity analysis of pool temperature which shows that for an increase of about 17 o C, heat removal from the containment to water pool is only slightly affected with value less than 3 percent.Keywords: Containment, Condensation, RELAP5, NuScale, Depressurization ABSTRAK STUDI NUMERIK PROSES KONDENSASI PADA SISTEM PENGUNGKUNG TERENDAM UNTUK SMR SAAT DEPRESURISASI TAK TERKENDALI.
