Abstract—the classical nuclear instrumentation in fast reactors monitors the core neutron flux from shut down to full power over ~10 decades. This wide range necessitates combination of various detectors and electronic systems, with interlocks and overlapping. Also there is a tradeoff between the accuracy and response times. To overcome this problem, a special technique, viz. principal component analysis in frequency domain is proposed. This paper discusses the detailing of the technique, results obtained, future scope.
