Water-Simulant Facility Installation for the Sodium-Cooled Fast Reactor KALIMER-600 and Global Flow Measurement

Abstract

Abstract. KAERI has developed a KALIMER-600 which is a pool-type sodium-cooled fast reactor with a 600MWe electric generation capacity. For a SFR development, one of the main topics is an enhancement of the reactor system safety. Therefore, we have a long-term plan to design the large sodium experimental facility to evaluate the reactor safety and component performance. In order to extrapolate a thermal hydraulic phenomena in a large sodium reactor, the thermal hydraulics phenomena is under investigation in a 1/10 th water-simulant facility for the KALIMER-600. In this paper, we shortly described the experimental facility setup and the measurement of the isothermal global flow behavior. For the flow field measurement, the PIV method was used in a transparent Plexiglas reactor vessel model at around 20 o C water condition.

Magnetohydrodynamic stabilizer suppressing gas entrainment for safety improvement in a sodium‐cooled fast reactor

“…In this study, the KSFR was used for evaluating the GE 38,39 . The LES model was adopted based on the results in Section 3.1.…”

“…The schematic of the 1/4 upper plenum of the KSFR is shown in Figure 1A. 38,39 The x-and z-directions are toward the right-hand and top sides, respectively. The radius and height are 1100 and 1400 mm, respectively.…”

“…Here, the KSFR, called Korea advanced liquid metal reactor (KALIMER), 38,39 was considered herein to evaluate the GE and MHD stabilization; the electrical output of the KALIMER is 150 MWe, and the flow rate at exit of the reactor core is 35 L/s (=2100 L/min). The IHX is installed at 90°, 180°, 270°, and 360°.…”

“…Therefore, the 1/4 partial mockup was considered in the previous study 38 based on the axisymmetric assumption; moreover, the geometry in only upper plenum was considered for simplification. The schematic of the 1/4 upper plenum of the KSFR is shown in Figure 1A 38,39 . The x ‐ and z ‐directions are toward the right‐hand and top sides, respectively.…”

“…In this study, the KSFR was used for evaluating the GE. 38,39 The LES model was adopted based on the results in Section 3.1. To satisfy the required SGS near the IHX and free surface, the total 486 314 structured cells were applied as shown in Figure 1B.…”
