Significant modifications have been made to the Reactor Cavity Cooling System test loop at the Center for Nuclear Reactor Technology and Safety - BATAN, from being originally water-cooled with a long piping system to being air-cooled with U-Type flow. Analytical prediction of the thermal parameters of a passive cooling system is needed to provide initial data on the characteristics of the system so that it can be used as a reference in the implementation of experiments. The method used in this prediction is entirely based on empirical data from the literature which is then processed into a MATLAB-based calculation program. This test loop is in the form of a hollow beam with a width of 0.3 m, a length of 0.8 m, and a height of 9 m which is divided into two spaces with the bottom parts are connected. One side of the cavity wall is an electric heater plate with dimensions of 0.8 m long and 9 m high. At the top of the two chambers, there are holes where the air enters and leaves after passing through the heating surface. With this study, it can be predicted the mass flow rate of air, the amount of power evacuated, and the resulting air temperature distribution. With 4 variations of heating temperature, namely 50 °C, 100 °C, 150 °C and 200 °C for air temperatures of 30 °C, it was predicted an increase in power from 498 W to 10255 W, an increase in mass flow rate from 0.031 kg/s to 0.064 kg/s, and an increase in evacuated air temperature from 47 °C to 188 °C. The results of this prediction can be used as reference data before the experiment is carried out. [ABSTRACT FROM AUTHOR] |
