The light-water reactor (LWR) is a type of thermal-neutron reactor that uses normal water, as opposed to heavy water, as both its coolant and neutron moderator – furthermore a solid form of fissile elements is used as fuel. Thermal-neutron reactors are the most common type of nuclear reactor, and light-water reactors are the most common type of thermal-neutron reactor.
Electronuclear cogeneration plant with light water reactor and system for capturing atmospheric co2 or for desalinating sea water without drawing liquid water therefrom or releasing same into the environment
The invention relates to a nuclear cogeneration plant with a light water reactor (LWR) and a system for capturing atmospheric CO2 or for desalinating sea water without withdrawing liquid water therefrom or releasing same into the environment. The invention essentially consists in using, in combination, a thermal storage loop, arranged between the primary circuit and the secondary circuit of a reactor, with a system for capturing atmospheric carbon dioxide or for desalinating sea water at the condenser of the secondary circuit.

Dual isolation valve system for fuel transfer tube in pressurized light water reactor nuclear power plant
PCT designated stageWO2026134519A1Operating means/releasing devices for valvesSlide valveIsolation valvePressurized water reactor
The dual isolation valve system for a fuel transfer tube in a pressurized light water reactor nuclear power plant, according to the present invention, is characterized in that: in order to withdraw nuclear fuel from a fuel building and reload nuclear fuel into a reactor within a reactor building through a fuel transfer tube, a motor-operated gate isolation valve and a manual isolation valve are installed at the front side of the fuel transfer tube, relative to the fuel building side, in order to fill and drain a reactor refueling water storage tank; the manual isolation valve on the fuel building side is maintained in an open state; a plurality of disc-fastening holes are formed along the outer circumference of the disc of the motor-operated gate isolation valve; a disc protrusion is inserted into the inside of the fuel transfer tube; a disc step circumference is larger than the outer diameter of the fuel transfer tube so as to seal the fuel transfer tube; and the disc of the motor-operated gate isolation valve moves downward due to the driving of a motor (M), causing the motor-operated gate isolation valve to block the fuel transfer tube and maintain the tube in a closed state, the disc being an isolation valve disc that functions as a blind flange.
