Abstract

Reactor power frequency spectrum measurements at various power levela-OW, 1KW, 50KW, 100KW were made with TRIGA-MARK-II. An ion chamber was exposed to reactor flux, and the fluctions in its output current were analyed in a tunable bandpass filter to get the frequency spectrum of these fluctuation. The measured frequency spectrum of pile determined the modules of modules of zero power transfer function and indicated a prompt neutron mean life time of (7.90$\pm$1.62)X10 sec based on effective delayed neutron faction of 0.0075. The absolute value of reactor power obtained by noise analysis agreed within 5% with the power meter indication at the power below 10Kw.

TRIGA MARK-II 원자로의 각출력에 대한 주파수스펙트럼을 측정하므로서 원자로의 전달함수의 계수율을 선정하였다. 랜덤한 파일잡음의 검출은 전전력에서 10-7A인 평행원부형 전리함을 이용하였다. 주파수스펙트럼은 동조형대역통과 여파기를 가지고 해석하여 원자로의 동특성과 그 피라미터를 구하고 전력측정을 하였다.
