Nuclear cogeneration plant having a reactor with an indirect thermodynamic cycle without extraction or discharge of liquid water from/to the environment

A nuclear cogeneration plant, comprising:

• at least one nuclear reactor, comprising:
• a first fluid circuit, called the primary circuit, comprising at least a first intermediate heat exchanger;
• a second fluid circuit, called the secondary circuit, comprising at least one steam generator acting as a second intermediate heat exchanger, at least one turbine connected to the second heat exchanger, a condenser connected to the turbine and to the second heat exchanger for cooling the steam leaving the turbine, converting the steam back into water, and returning the water to the second heat exchanger;
• an alternator coupled mechanically to the turbine and designed to be connected to an electricity grid;
• a third fluid circuit configured as a closed loop for storing thermal energy, in which there flows a heat transfer fluid, comprising:
• at least a first reservoir, called the high-temperature reservoir, connected to the first intermediate heat exchanger;
• at least a first hydraulic pump, connected to the high-temperature reservoir and to the second intermediate heat exchanger;
• at least a second reservoir, called the low-temperature reservoir, connected to the second intermediate heat exchanger;
• at least a second hydraulic pump, connected to the low-temperature reservoir and to the first intermediate heat exchanger;
• and
• at least one dry-air cooling device connected in a closed loop to the condenser of the secondary circuit of the reactor.
