Automatical panel establishment of cooling water provider in the ventilation system of intermediate radiation zone of the G.A. Siwabessy reactor

It has been established automatical panel of chilled water supply system in the intermediate radiation zone of the RSG-GAS ventilation system. It has been done by installing a thermostat sensor in the entry of water pipe lines. The scope and steps of work done consist of studying how the old system, making the plans for the new panel, making and assembling the control panel and running test of the panel. From the results of the running test using basic mode chiller shows that at temperatures < 11,5°C chiller that operates is one unit, at temperatures of 11,5°C to 13,5°C chiller that operates are two units while at temperatures >13,5°C chiller that operates are 3 unit. By the operation of the indicator lights that are mounted in the control panel and the operation of three chillers at the time of the running test shown that the automated panel water supply system is ready to be used to support the operation of the intermediate ventilation system radiation zone of the RSG-GAS.
