Open pool type research reactor is widely designed in consideration of the reactor utilization and accessibility. A coolant flows into a reactor structure assembly and goes to fuel assemblies in the downward flow type reactor. Inlet and outlet pipes of the primary coolant system are directly connected to the reactor structure assembly. The primary coolant system circulates the coolant from the reactor core to the heat exchanger in order to remove the fission heat continuously. There are holes in the reactor structure assembly for the by-pass flow path and the reactor utilization. The strainer is installed on each hole to prevent to enter foreign materials from the reactor pool to fuel assemblies.
When the loss of coolant accident occurs in the pipe of the primary coolant system, the coolant is flowed out from the reactor pool to the primary coolant system through strainers. The loss coefficient of the strainer is one factor to determine the flow rate. The flow field of the strainer is numerically simulated to calculate the loss coefficient based on the velocity and pressure. The loss coefficient of 8.0 ± 1.0 is obtained from the numerical and analytical methods.
