ANALISIS UNJUK KERJA PENUKAR KALOR REAKTOR SERBAGUNA GA. SIWABESSY MENGGUNAKAN SATU JALUR PENDINGIN

The performance analysis of multipurpose reactor G.A. Siwabessy heat exchange analysis using single line cooling. The performance of heat exchanger and the supporting component should decrease, because the reactor has been operated since 14 years. The evaluation and the analysis has been done to know the perforactormance of heat exchanger. This investigation has been done using the computer code named CATHENA which was developed by Atomic Energy of Canada Limited (AECL). The calculation simulation is done with the reactor system model with single line and reactor power is 10 MW. The result are compared with experiment data at same condition and provide that the correction factor of the above parameters. The correction for each parameters are the followings: the temperature of the primary side of heat exchanger at the inlet is 13.97%, at the outlet is 3.8%. At the secondary side of heat exchanger, the inlet temperature is 19.86% and the outlet temperature 11.95%. The operational pressure of the inlet on the primary side HE is 11.54% and the outlet 49.37%. The secondary side is 28.87% and 1.5%. The inlet flow rate of the primary side 14.9% and the secondary side 6.78%. This result shows the minimum the maximum correction factor 1.5% and 49.37% respectively.
