NEUTRON FLUX MEASUREMENTS IN THE ROTARY RACK OF THE REAKTOR TRIGA PUSPATI
Abstract
ABSTRACT
Neutron flux is an essential parameter in evaluating the performance of research reactors. The neutron flux distribution in the core region of the Reaktor TRIGA PUSPATI (RTP) has been measured through the neutron activation analysis method, using bare and cadmium covered gold wires activation. The aim of the measurement is to determine the neutron flux in the rotary rack at the end-of-cycle (EOC) RTP core-15. The wires were irradiated in the rotary specimen rack with the reactor operated at 750 kW. The gamma activities of the wires are measured by using high-purity germanium (HPGe) gamma detector.
ABSTRAK
Fluks neutron merupakan parameter penting dalam penilaian prestasi sesebuah reaktor penyelidikan. Taburan fluks neutron terma di dalam teras Reaktor TRIGA PUSPATI (RTP) diukur melalui teknik analisis pengaktifan neutron menggunakan pengaktifan wayar emas dan wayar emas dilindungi rod kadmium. Objektif pengukuran ini ialah menentukan nilai fluks neutron di rak berputar di penghujung kitaran konfigurasi teras RTP yang ke-15. Eksperimen dijalankan di fasiliti penyinaran rak berputar dengan kuasa reaktor 750 kW. High-Purity Germanium (HPGe) Gamma Detector digunakan untuk pengukuran aktiviti gamma wayar yang disinarkan.
