The invention belongs to the technical field of pressurized water reactor nuclear power stations, and particularly relates to a heat-electricity-water combined system suitable for a large pressurized water reactor nuclear power unit and a production process. In the invention, a first nuclear power unit and a second nuclear power unit forms a nuclear steam supply system; a superheater, a steam generator, a deaerator, a secondary feed water heater, a primary feed water heater and a secondary water feeding pump form an industrial steam production system; a desalted water feeding pump, a water feeding tank, a desalted water facility, a seawater desalination facility, a heater, a first regulating valve, a second regulating valve, a seawater taking port, a seawater draining port, a standby fresh water taking port and a production water user form a seawater desalination and desalted water supply system; and a drainage pipeline returns to a pressurized water reactor nuclear power unit condenser through a third regula
