Development of Monitoring and Control Systems in Cavity Cooling System Test Loop for The Experimental Power Reactor

Abstract

The Experimental Power Reactor as a fourth type of reactor currently being developed in Indonesia is high temperature gas cooled reactor which has a passive cooling system. This passive cooling system uses the principle of natural circulation through changes in water density and called as reactor cavity cooling system. To study the reactor cavity cooling system, a test facility will be created at BATAN which is called the Cavity Cooling Test Loop. This test facility consists of mechanical systems, piping and instrumentation. The instrumentation are includes temperature measurement, flow rate, pressure and heating control. Measurement and control monitoring systems that are needed in order to get data effectively and efficiently have not been made. Therefore, in this study, LabVIEW was used to create monitoring and control programs. A program to monitor temperature, flow rate and pressure has been made with a measurement point of 60 thermocouples, 1 flowmeter, and 1 pressure sensor. The heaters control program is made for 10 units with control of each heater ranging from 200°C to 900°C. Simulation has been done to test the performance of the program using DAQ simulator. Based on the simulation results, the program can be applied to the test facility by paying attention to the input type in the DAQ module.
