A TRANSISTORIZED REACTIVITY COMPUTER
Reactor kinetics equations are shown to consist of three major components: a fast term, a product or quotient, and a summation of transient terms. These can be synthesized by using a number of simpIe R-C networks having time constants related to the fast time constant and to the decay constants of the various groups of delayed neutron emitters, plus either an analog multiplier or divider. If an input signal proportional to neutron flux or reactor power is applied to this network, the output is proportional to reactivity. A circuit is shown that incorporates these principIes, using a diode divider. Curves are presented of output reading, indicating transient reactivity, for input currents having constant positive period, as obtained from a motordriven potentiometer. It is shown that these curves are in agreement with calculated curves of reactivity for such periods. (auth)
