Measurement of the SRE Power Coefficients and Reactor Parameters Utilizing the Oscillation Techniques

An experiment was performed on the SRE, wherein relative stability analysis and the determination of core dynamic parameters were accomplished. The technique was one of producing a sinusoidal change in reactivity through oscillation of an existing control rod and measuring the reactor flux and temperature responses by use of a correlation technique which allows measurement of only the fundamental frequency of reactor response. The ability to isolate the fundamental frequency permitted the analysis of data with distortions or small signal to noise ratios present. By isolating individual gains and response times, the simplified individual transfer functions of fuel, moderator and coolant were determined. These transfer functions were used in the equation for the power coefficient to separate the isothermal temperature coefficients of reactivity.
