Simulator of Reactor Kinetics

摘要

This paper describes the design concepts of digital-to-analog simulators of nuclear reactor reactivity and gives information pattern about power signal which corresponds to fixed value of reactivity. The main design concept for digital-to-analog simulator is decadic partition of power signal level with normalization of decades to the specified number which corresponds to number of bits of digital-to-analog converter (DAC) and storing of the duplicated information concerning the power signal. This paper proposes the design of simulator based on 12-bit DAC. The simulator has ≤1% relative error for reactivity value corresponding to output signal of DAC-simulator within three decades of power signal variation.
