The thermal-hydraulic research supporting the development of an integral type reactor named System-integrated Modular Advanced ReacTor (SMART) is discussed. First, SMART program introduced. Standard Design Approval (SDA) for was certificated in 2012 based on extensive technical validation activities during 2009 to 2012, and a set passive safety systems (PSSs) designed validated 2013 2015 after Fukushima Daiichi accident. During 2016 2018, Kingdom Saudi Arabia Korea conducted 3-year project...
The Strouhal number from trapezoidal cylinders depends on the Reynolds as well height ratio, which is ratio of rear face to that front face. For Re=100 and 150, distributions numbers show their minimum values at a 0.7 0.85, respectively. However, for Re=200, variation increases square section decreases. After showing maximum value 0.7, it decreases It then again smaller ratios. Movement flow separation point corners change secondary vortex strength are important factors in determining...
Vortex shedding behind a square cylinder in an oscillatory incoming flow is studied at Reynolds numbers of 80, 100 and 200 by numerical solutions. The forcing frequencies investigated for the are ff/fso=0.4∼4.0 amplitudes normalized mean velocity 0.1, 0.2 0.4, where fso vortex frequency under steady ff flow. In lock-on region, periodic state there strong regularity between drag lift forces. different phase diagram forces brought on mode. difference nearly same magnitude 65∼70 degrees region....
Small reactors can apply to local power demands or remote areas. SMART, which produce 90 MWe of electricity and 40,000 tons/day sea-water desalination for a 100,000 population city, is promising advanced integral type small reactor. The thermal hydraulic analysis code with drift flux model, TASS/SMR, was developed conservative simulation break loss coolant accident in SMART. Taking into account SMART-specific inherent characteristics, the adopts Chexal–Lellouche correlation model. capability...
The system-integrated modular advanced reactor (SMART) new phase (SMART-P) with a rated thermal power of 65.5 MW is currently being developed at the Korea Atomic Energy Research Institute. It an innovative design to achieve high degree safety by adopting inherent safety-improving features and passive systems. Realistic conservative calculations parameter study for steam-line pipe break have been carried out means TASS/SMR code. A set transients whole system SMART-P investigated from point...
