Scientific design of a large-scale sodium thermal–hydraulic test facility for KALIMER—Part I: Scientific facility design

Scientific design of a large-scale sodium thermal–hydraulic test facility for KALIMER—Part II: Validation of reactor pool design using CFD analyses

“…The design parameters of the test facility were determined using an appropriate scaling method for similarity, and it has been described in the Part I paper (Hong et al, 2013). The present work validates the scaled reactor vessel design from the multi-dimensional temperature and flow distribution perspectives using three-dimensional CFD analyses for both the KALIMER-600 prototype and the one-fifth scale model.…”

“…However, the present CFD analyses do not consider the temperature variations of the thermodynamic properties of sodium; instead, constant values were used. The variations of the sodium temperature based on the designed temperature of the hot and cold pools was approximately 150 K, and the thermodynamic properties varied by less than 10% in this level of temperature variation (Hong et al, 2013). The representative thermodynamic properties of sodium are presented in Table 2.…”

“…According to the scaling criteria given in Part I (Hong et al, 2013), the scaling ratios of the one-fifth model to prototype are 1/5 for the length, 1/25 for the area, 1 ffiffiffi 5 p for the velocity, 1=ð25…”

“…The thermal hydraulic test facility was scaled down to be one-fifth of the size of KALIMER-600. The sizing of the test facility was determined based on a similarity scaling law as described in Part I of this research (Hong et al, 2013).…”
