Kajian unjuk kerja detektor Fluks Neutron di daerah Intermediate pada reaktor serbaguna G.A. Siw Abessy

Abstract

Telab dilakukan kajian unjuk kerja detektor fluks neutron di daerah Intermediate dari segi instrumentasi neutronik untuk mengetabui karakteristik detektor CIC yang digunakan pada daerah intermediate dan menentukan kemampuan operasi instrutnennya. lJnjuk kerja dan kemampuan operasi instrumentasi ditentukan dengan mernbandingkan basil pengukuran dengan standar yang diberikan oleh Into-atom. Dengan memperhatikan basil dalam uji kanal pengukuran maka dapat diketahui kelayakan kanal rasing-rasing detektor.Selain itu pula untuk mengetabui karakteristik detektor C1C dibuatlab kurva karakteristik kompensasi. Bari kajian unjuk kerja berdasarkan metode pembanding, uji kanal pengukuran, dan kurva karakteristik kompensasi diperoleb basil babwa terdapat penyimpangan kabel koaksial pada detektor JKT 02 CX 811 dan .MKT 02 CX 821. Kanal pengukuran kedua detektor masib dalam kondisi balk. •Dengan merujuk basil yang didapat dari kurva karakteristik kompensasi, detektor :KT 02 CX 821 terdapat penyimpangan. The assessment of the flux neutron's detector have been worked in the intermediate range of the instrumental neutron side. The purpose of this assessment is to obtain the characteristics of C1C's detector that been used in the intermediate range and to determine ability of the instrumental operation. The assessment and ability of the instrumental operation was determined by comparing the result of measured with the standard of the Inte•atom. By concerning the result of the measuring canal test to obtain the ability of the canal of each detectors, the curve of compensation characteristics was made to obtain the characteristics of CIC's detector. Result of the assessment, according to the method of comparing, the measuring canal test and the curve of compansation characteristics, exhibits the deviations of coaxial cable on the detector of JKT 02 CX 811 and JKT 02 CX 821. The measuring canal of those detectors was in a good condition. According to the result from the curve of compensation characteristics that shown a deviation on detector of MKT 02 CX 821
