FIELD: reactor measurements; reactor core monitoring.
SUBSTANCE: proposed device has pulse-current ionization chamber, spectrometric amplifier, amplifier signal-to-code converter, three discriminators, three dividers, four pulse shapers, four run-code converters, control and processing device. Spectrometric amplifier output is connected to inputs of discriminators; outputs of first, second, and third discriminators are connected to inputs of first, second, and third dividers, respectively. Output of first discriminator is connected through first pulse shaper to input of first run-code converter. Output of first divider is connected through second pulse shaper and second run-code converter to unibus. Output of second divider is connected through pulse shaper and third run-code converter to unibus. Output of third divider is connected through fourth pulse shaper and fourth run-code converter to unibus. The latter is connected to control and processing device.
EFFECT: enhanced measurement accuracy.
