IMPULSE-CURRENT IMITATOR OF KINETICS OF NUCLEAR REACTOR Russian patent published in 2006 - IPC G06G7/48 

FIELD: analog computer engineering, possible use for checking devices for measuring reactivity of nuclear reactors.

SUBSTANCE: impulse-current imitator of kinetics of nuclear reactor contains measuring amplifier, enveloped by check connection, and inverting amplifier, a group of N circuits of input resistors and commutating keys, high voltage amplifier, a group of circuits of resistors for forming output current and keys for selecting value of current, reactivity sign selection commutator, voltage to frequency converter, and generator of output impulses. Additionally, imitator contains control block and N controllable commutators.

EFFECT: increased trustworthiness of imitation of substance of nuclear reactor being modeled in area of high absolute values of reactivity.
