Abstract

EVALUASI  FLUKS NEUTRON THERMAL DAN EPITHERMAL DI FASILITAS SISTEM RABBIT RSG GAS TERAS 89.  Pengukuran fluks neutron thermal dan epithermal di fasilitas iradiasi sistem rabbit dipandang perlu dilakukan kembali sebagai  evaluasi. Metode yang digunakan adalah dengan melakukan aktivasi keping Au terbuka, dan keping Au yang terbungkus Cd. Keping diiradiasi pada posisi RS-1, RS-2 dan RS-4 selama 300 detik dalam reaktor berdaya 15MW. Hasil pengukuran fluks neutron thermal di posisi RS-1 adalah sebesar 4,4689E+13 n/cm2.s dan epithermal 4,014E+12 n/cm2.s. Untuk posisi RS-2 adalah 4,0631E+13 n/cm2.s untuk thermal dan 4,280E+12 n/cm2.s untuk epithermal. Posisi RS-4 adalah 4,2152E+13 n/cm2.s untuk thermal dan 3,531E+12 n/cm2.s  untuk epithermal. Koreksi pengukuran dilakukan dengan menggabungkan faktor penyumbang kesalahan. Nilai  ketidakpastian      pada   posisi RS-1 adalah 5,068 %,    RS-2;  5,096 % dan RS-4 adalah 5,093 %. Bila dibandingkan dengan hasil pengukuran fluks neutron sebelumnya yaitu pada teras ke 54, hasil pengukuran fluks neutron ini tidak mengalami perbedaan yang signifikan. Pengukuran secara rutin diperlukan teristimewa pada setiap adanya perubahan pada konfigurasi bahan bakar reaktor untuk mengetahui besaran fluks neutron pada setiap posisi iradiasi. Kata kunci: fluks neutron thermal, epithermal, sistem rabbit  ABSTRACTEVALUATION OF THERMAL AND  EPITHERMAL NEUTRON FLUX  IN THE RABBIT SYSTEM  OF THE RSG GAS 89TH CYCLE FACILITY. Re-measurements of thermal and epithermal neutron flux at the irradiation facility of  rabbit system is necessary  for evaluation. The method used is to perform the activation of Au foil, and Au-wrapped Cd. The foils were irradiated at position RS-1, RS-2 and RS-4 for 300 seconds in a 15MW power  reactors. The results of measurements of thermal neutron flux in the position of RS-1 is 4,4689E + 13 n / cm2.s and epithermal is  4,014E + 12 n / cm2.s. While in the position of RS-2 is 4,0631E + 13 n / cm2.s for thermal and 4,280E + 12 n / cm2.s to epithermal. The position of the RS-4 is 4,2152E + 13 n / cm2.s for thermal and 3,531E+12 n/cm2.s  for epithermal. Measurement correction is done by combining the factor of contributor’s mistake. The uncertainty factor to the position of RS-1 is 5.068%, RS-2; 5.096% and RS-4 is 5.093%. When compared to the results of previous measurements of neutron flux on core 54, the results of neutron flux measurement is not experiencing a significant difference. Measurements are routinely required especially on any changes to the configuration of the reactor fuel to determine the amount of neutron flux at the position. Keywords: thermal and epithermal neutron flux, rabbit system

Abstract

Currently the tour and travel business in Indonesia has experienced a rapid increase. This is seen from the high interest of Indonesian travelers to travelThis research is quantitative, the sample taken is active students in the even semester of the Faculty of Economics and Business, Indonesian Christian University, as many as 96 respondents. To measure the level of satisfaction of traveloka consumers, a performance analysis and performance of the Cartesian diagram is used, and the variables used in this study are professionalism and skills, attitudes and behavior, accessibility and flexibility, reliability and trustworthiness, recovery and reputation and credibility. Keywords : professionalism and skills, attitudes and behavior, accessibility and flexibility, reliability and trustworthiness, recovery and reputation and credibility, customer satisfaction and services quality
