Abstract
EVALUASI PARAMETER NISBAH NEUTRON TERMAL TERHADAP EPITERMAL f DAN PARAMETER DI FASILITAS IRADIASI SISTEM RABIT RERAS RSG GA SIWABESSY. Telah dilakukan pengukuran parameter nisbah fluks neutron termal terhadap epitermal f di posisi fasilitas iradiasi sistem ‘rabbit’ RS-1 s/d RS-4 dan parameter teras silisida reaktor RSG-GAS. Pengukuran dilakukan dengan metoda aktivasi keping. Dalam penentuan parameter dilakukan pencocokan persamaan pangkat (power) pada daerah energi epitermal terhadap spektrum neutron. Berdasarkan pencocokan tersebut dapat ditentukan parameter sebesar 0,0267, 0,0255 dan -0,0346 masing-masing pada posisi sistem rabbit, IP2 dan CIP reaktor RSG-GAS. Besarnya nisbah fluks neutron termal terhadap fluks epitermal f di fasilitas iradiasi sistem rabbit RS-1 hingga RS-4 mendekati 40.
ABSTRACT
EVALUATION OF THERMAL TO EPITERMAL NEUTRON FLUX RATIO f AND PARAMETER IN RABBIT SYSTEM IRRADIATION FASILITY OF RSG G.A. SIWABESSY REACTOR. Determination of neutron flux thermal to epithermal ratio f and parameter has been done in irradiation facility of RSG G.A. Siwabessy reactor. Those parameters are needed to determine the concentration of an element in a sample using ko NAA method. Parameters f was measured using foil activation method and parameter was obtained from power function fitting at epithermal neutron spectrum. Based on the fitting method the parameter was determined of 0.0267, 0.0255 and -0.0346 at system rabbit, IP2 and CIP irradiation position. The neutron flux thermal to epithermal ratio f at all rabbit system is closed to 40.
