Evaluation of Cooling Tower Performance RSG-GAS Reactor Using One Line Cooling System

Utilization of the reactor operation must be done as optimal as possible, so that reactor operation needed efficiently. Reactor power needed in the operation continuously maximum only 15 MW, in this case can be anticipated by doing only using one line cooling system from two line cooling system is available. The consequences by using one line cooling system, it will be impact among performance of cooling tower, for that it is needed research about this case. The research of Multipurpose Reactor GA. Siwabessy's cooling tower when the reactor operator by one line cooling system conducted using the data of operation at 10 MW. The results of calculation showed that for design condition, the ratio of water flow rate to air (L/G) is 1.52, and number transfer unit (NTU) is 0.348. For experiment condition, it is achieved the average of L/G and NTU are 1.37 and 0.342 respectively. The performance value of cooling tower from experiment condition is 91%. That value is greater than feasible value for operation capability cooling tower from acceptable test procedure for industrial cooling tower namely 80%. (author)
