TASS/SMR-S is thermal-hydraulic design code for safety analysis of SMART plant. SBLOCA is considered as the design basis accident in the SMART. The capability of TASS/SMR-S for SBLOCA analysis was assessed using LOFT L3-7 as TMI action plan. Because TASS/SMR-S has been developed only for SMART, which is an integral reactor with helical steam generator heat exchanger, the steam generator model of TASS/SMR-S cannot be used directly for LOFT experiment that involves the use of U-tube steam generator. Therefore, the general heat structure model of TASS/SMR-S was used for modeling the SG heat exchanger. Nevertheless, TASS/SMR-S predicted important thermal-hydraulic parameters such as system pressure, fluid temperatures, and cladding temperature of reactor within reasonable error ranges. Further, TASS/SMR-S was applied to simulate SBLOCA in the SMART plant. In this simulation, thermal hydraulic parameters similar to those predicted in LOFT L3-7 were predicted.
► TASS/SMR-S code is thermal hydraulic design code for SMART. ► Thermal hydraulic design code must be assessed using ITE such as LOFT and semiscale test. ► TASS/SMR-S was assessed for SBLOCA using LOFT L3-7 with good agreement. ► It is proven that TASS/SMR-S has feasibility of application to SBLOCA. ► TASS/SMR-S was applied to simulate SBLOCA scenario of SMART.
