The maximum period sequence binary signal has been applied to measurements of the JRR-3 frequency response at 10 MW. Three measurements have been made to cover the frequency range of 0.003 to 10 radians/sec. The measurements were readily made when the reactor temperature was in equilibrium. Even when it was not, and the reactor power was varying slowly, a power drift compensating system made it possible to carry out accurate measurements. The results obtained under equilibrium and non-equilibrium conditions agreed well with each other.
A simple mathematical model has been used to predict the JRR-3 high power dynamics. The frequency response computed with the use of this model also agreed fairly well with the experimental data.
