REACTIMETRE ADJUSTMENT METHOD Russian patent published in 2010 - IPC G21C17/10 

FIELD: power industry.

SUBSTANCE: reactimetre adjustment method consists in carrying out subsequent operations. First, there performed is discrimination of current pulses of fission chamber above level of high-frequency interference; then there determined is neutron flow density up to the transition level of counting channel to current level; there determined are readings of counting and current channels of reactimetre during transition process and neutron flow density is increased above transition level. After that neuron flow density is decreased below the above level, and by determining the counting channel readings, current value is calculated and compensation of false currents of fission chamber is performed.

EFFECT: invention allows decreasing measurement errors in transient operating modes of reactimetre and increasing adjustment accuracy.
