Abstract

ANALISIS STABILITAS SUHU TERAS REAKTOR TRIGA 2000 BANDUNG AKIBAT TRANSIEN REAKTIVITAS. Penelitian ini dilakukan untuk memperoleh gambaran tentang stabilitas dan respon transien suhu teras akibat perubahan reaktivitas selama operasi rutin. Diasumsikan reaktor sebagai suatu sistem linier tergumpal dengan neutron kasip satu grup, pengaruh fraksi hampa serta racun xenon terhadap reaktivitas diabaikan. Dan hasil evaluasi yang dilakukan dengan metode Nyquist, metode Root Locus dan diagram Bode diperoleh informasi bahwa, sistem selalu dalam keadaan stabil berapapun penguatanya dan mempunyai respontransien yang baik, karena perbandingan koefisien suhu negatif air terhadap bahan bakar adalah 1,54 lebih kecil dan batas atasnya, yaitu 14 x 106. Dengan menggunakan diagram Bode dapat ditunjukan pula sistem mempunyai kestabilan relatif dengan gainmargin 65 db dan phase margin 41° yang terjadi pada frekuensi-frekuensi jauh di atas frekuensi termal.

Abstract

The FLUENT V4.25 program is the CFD (Computational Fluid Dynamics) simulation. It can be used for fluid flow and heat transfer analyses and others. Regarding the program, the test is needed to know the validity, to verify that the program will give good output. Based on the test using experimental data on four heated parallel rod bundles, the output FL UENT V4.25, it gave a good result, where the differences between calculation and experimental data are not significant. It is expected that the FLUENT V4. 25 program may achieve success in thermo-hydraulic analysis on other similar systems.

Abstract

The thermohydraulic aspect utilization on a nuclear reactor is very dominant, because the system gives limitation on the reactor operation. Regarding the problem, theoretical analysis of thermohydraulic aspect is done for a research reactor of 2 MW with hexagonal configuration of fuel elements With an assumption that the power generation each fuel element is the same and the other facilities are neglected, the output of FLUENT V4.25 program gave information that theoretically this research reactor can be operated on thermal power of 2 MW.
