FIELD: physics.
SUBSTANCE: in the method of measuring neutron power of a nuclear reactor in absolute units F=V·γ, where V is the reactor power value in arbitrary units, γ is a coefficient of proportionality, neutron power of the nuclear reactor in arbitrary units is measured as the average count rate of the neutron detector in a stationary critical state using measurement means. The coefficient of proportionality is calculated using an autocorrelation function value. The means of measuring the number of neutrons used is an ionisation chamber for determining fluctuation of the number of neutrons. The method includes separately measuring the average value of current of the ionisation chamber and the fluctuating component of the current of the ionisation chamber continuously over time with a discrete interval, calculating the autocorrelation function of the fluctuating current of the ionisation chamber and then calculating the coefficient of proportionality.
EFFECT: increasing the maximum values of F.
