Abstract
In this research, data acquisition studies for signals from the neutron detectors and fuel thermo -couples
of ITU TRIGA MARK-II nuclear reactor was implemented. Also, spectral properties related to the data
were examined using frequency and time-frequency domain techniques. Fundamental frequency
component at 50 Hz of electric power network and its harmonics were removed from the original
signals by wavelet analysis approach.
Key Words : TRIGA MARK II Nuclear Reactor, frequency domain analysis, Wavelet Analysis
ÖZET
Bu çalýþmada ÃTÜ kampüsünde bulunan TRIGA MARK-II tipi nükleer reaktörde, güvenlik kanalý
nötron detektörleri ve yakýt sýcaklýðý termo -çiftine iliºkin veriler toplanarak frekans ve zaman-frekans
taným bölgesi analizleri gerçekleþtirilmiþtir. Ayrýca 50 Hz'lik þebeke frekansý etkisi dalgacýk analizi
tekniði ile filtrelenmiþtir.
