METHOD OF NUCLEAR REACTOR CONTROL Russian patent published in 2014 - IPC G21C7/36 

FIELD: power engineering.

SUBSTANCE: method of nuclear reactor control is carried out by maintenance of specified temperature of coolant at the outlet of the reactor by variation of plant capacity by control elements of reactivity variation, by means of measurement of primary circuit coolant parameters. A setpoint of primary circuit coolant average temperature is introduced, a signal of deviation of the calculated average coolant temperature from this setpoint is generated, and using the produced signal, they regulate circulation of reactor coolant, besides, additionally they introduce process of connection and disconnection of the coolant average temperature controller. At the same time they disconnect the average temperature controller at the moment of connection of the regulator for maintenance of the specified coolant temperature at the outlet of the reactor, and connect it at the moment of completion of action of the controller of coolant temperature maintenance at the outlet of the reactor.

EFFECT: elimination of possible errors in calculation of dependence of steam temperature on coolant temperature, speed of reactor coolant optimisation and optimisation of operational properties of steam, efficiency factor.
