Abstract EN
In an open-pool type research reactor, the primary cooling system can be designed to have a downward flow inside the core during normal operation because of the plate type fuel geometry.
There is a flow inversion inside the core from the downward flow by the inertia force of the primary coolant to the upward flow by the natural circulation when the pump is turned off.
To delay the flow inversion time, an innovative passive system with pump flywheel and GCCT is developed to remove the residual heat.
Before the primary cooling pump starts up, the water level of the GCCT is the same as that of the reactor pool.
During the primary cooling pump operation, the water in the GCCT is moved into the reactor pool because of the pump suction head.
After the pump stops, the potential head generates a downward flow inside the core by moving the water from the reactor pool to the GCCT and removes the residual heat.
When the water levels of the two pools are the same again, the core flow has an inversion of the flow direction, and natural circulation is developed through the flap valves.
