CONTROL METHOD FOR A PRESSURIZED WATER NUCLEAR REACTOR

摘要

This invention relates to a control method for a pressurised water nuclear reactor, said reactor comprising a core generating thermal power; means of acquiring magnitudes representative of core operating conditions (thermal power, temperature of the primary coolant); said method comprising a step to regulate the temperature of the primary coolant if the temperature of the primary coolant for a given thermal power is outside a predefined set temperature interval (ΔTREF) depending on the reactor power, said set temperature interval (ΔTREF) being characterised by a variable amplitude (ΔT) on a thermal power range between N % and 100% nominal power, where N is between 0 and 100; a zero amplitude at 100% nominal power; a zero amplitude at N % nominal power; said regulation not taking place while the temperature of the primary coolant is inside said temperature interval (ΔTREF) for a given thermal power.

1. A method of controlling a pressurised water nuclear reactor, said reactor comprising:
a core generating thermal power; means of acquiring magnitudes representative of core operating conditions (thermal power, temperature of the primary coolant); said method comprising regulating the temperature of the primary coolant if the temperature of the primary coolant, for a given thermal power, is outside a predefined set temperature interval (ΔTREF) depending on the reactor power, wherein said set temperature interval (ΔTREF) comprises: a variable amplitude (ΔT) on a thermal power range between N % and 100% nominal power, where N is between 0 and 100; a zero amplitude at 100% nominal power; a zero amplitude at N % of the nominal power;said regulation not taking place while the temperature of the primary coolant is inside said temperature interval (ΔTREF) for a given thermal power.
