ABSTRAK

Telah dilakukan penelitian yang berjudul pemetaan fluks neutron pada kolom iradiasi sistem transfer pneumatik pasca perubahan bahan bakar reaktor Kartini. Tujuan dari penelitian ini adalah mendapakan pemetaan fluks neutron pasca perubahan bahan bakar dan nilai banding cadmium. Metode pengukuran fluks neutron dilakukan dengan metode tidak langsung yaitu Analisis Aktivasi Neutron (AAN). Dalam penelitian ini menggunakan sampel berupa  yang diiradiasi dalam fasilitas iradiasi sistem transfer pneumatik. Pencacahan sampel menggunakan detektor Geiger Muller yang telah terkalibrasi sebelumnya. Dari hasil penelitian fluks neutron termal yang diperoleh sebesar (1,611094,64104) n cm-2 s-1. Sementara itu, untuk nilai banding cadmium diperoleh sebesar 1,30(9,9310-6).

Kata kunci: Neutron termal, nilai banding cadmium, pemetaan fluks neutron, sistem transfer pneumatik.

ABSTRACT

A neutron flux mapping study was conducted on the irradiation column of the pneumatic transfer system after the change of Kartini reactor fuel. The purpose of this research is to obtain neutron flux mapping after the change of fuel and cadmium appeal value. Neutron flux measurement method is done by indirect method of Neutron Activation Analysis (AAN). In this study using  samples  that are irradiated in the irradiation facility of the pneumatic transfer system. Sample enumeration using Geiger Muller detector that has been previously calibrated. From the results of thermal neutron flux research were obtained (1,611094,64104) n cm-2 s-1. Meanwhile, for the cadmium appeal value was 1.30 ± (9.93 × 10-6).

Keyword: Thermal neutron, cadmium appeal value, neutron flux mapping, pneumatic transfer system.
