The heat generated from the core of a research reactor is removed by a primary cooling system (PCS). Most reactors of relatively low power are designed using an open type reactor and pool. Thus, the primary coolant can be discharged to the reactor pool. However, the discharged coolant toward the top of the open type pool should be minimized for operator safety because it contains many kinds of radio-nuclides. This means that it is important for a PCS discharge header to be designed for minimizing bulk flow in the pool. ANSYS-CFD was employed to design a PCS discharge header and to analyze the flow characteristics in the pool. Several discharge headers were simulated with a similar scaled geometry and the boundary conditions of an actual research reactor. To minimize the bulk flow toward the top of the pool, it was analyzed that the magnitude and direction of velocity at the hole of the discharge header should be reduced. The results showed that the CFD analysis can be used as a tool for designing and modifying the PCS discharge according to various types of reactor pools.
