METHOD OF SIMULATING NUCLEAR REACTOR REACTIVITY Russian patent published in 2009 - IPC G06G7/54 

FIELD: physics; computer engineering.

SUBSTANCE: present invention relates to hybrid computer technology and can be used for calibrating devices for measuring reactivity of nuclear reactors. In the process of step accessing memory on the first step, the first element of the second array is stored for time Δt, equal to the access cycle, in an auxiliary memory device. On each step, starting with the second, the stored element is replaced in the auxiliary memory device by the previous element of the second array and is stored for a time Δt. On each step, the first analogue signal is generated, the value of which is given by the current element of the second array, and the second analogue signal, the value of which is given by the stored array element of the auxiliary memory device. The difference between the second and first analogue signals is integrated on the time interval Δt under the condition for equality of constant integration time to the access cycle and the output signal is generated from the obtained integral signal.

EFFECT: reduction of memory, simplification of the design of the simulator, improvement of its size and weight characteristics, cutting on time for preparing data when programming the control unit of the simulator and reducing expenditure on components during manufacture.
