Description
By use of thermal-hydraulic analysis code ''STREAM'', numerical calculations were carried out on the steady-state fluid flow in the 16N decay tank which is to be installed in the primary cooling system of upgraded JRR-3. This report presents the analytical results of numerical calculations for the 16N decay tank. For the design of 16N decay tank, it is necessary to realize as uniform a flow distribution in the tank as possible so as to prolong staying time of fluid in the tank, for effectively decaying in the tank 16N which was produced in the core. As the results, the configuration, the flow area and so on of the tank could be obtained which can satisfy the staying time of fluid in the tank which is required from the viewpoint of shielding of the upgraded JRR-3.
