Abstract : Noise analysis experiments were conducted on the TRIGA-F reactor at the Armed Forces Radiobiology Research Institute at Bethesda, Maryland. A pseudo-random reactivity perturbation was inserted into a cold critical core. Power level fluctuations were monitored and an estimated transfer function was constructed. From graphical plot analysis, the breakpoint frequency corresponding to beta/1 was measured to be 183 (units) 1/sec. This is the first such measurement on a TRIGA-F reactor by forced oscillation and is accurate to accepted values.
