FIELD: nuclear physics and equipment.
SUBSTANCE: invention relates to means of determining response speed and accuracy of a reactivity calculator. Signal of neutron flux density of the nuclear reactor rated for reactivity is introduced into detector signal generator, in which neutron flux density signal is converted into signal identical to real signal of neutron detector, which is sent to the converter of the signal of the neutron detector into an electrical signal, the converted electric signal of the neutron detector is fed to the input of the evaluator of reactivity from which the response signal of the attested reaction computer is sent to the recording equipment. Further, this signal is compared to a reference value of reactivity, by the difference of which a reactivity calculator is certified.
EFFECT: high reliability and accuracy of determining error and response time during physical start-up and operation of a nuclear reactor.
