Abstract

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 regulating valve and a fourth regulating valve to form a steam condensation water system. On the premise of ensuring nuclear safety, a nuclear power unit has the capabilities of producing industrial steam and producing fresh water through a seawater desalination technology.

Description

technical field [0001] The invention belongs to the technical field of pressurized water reactor nuclear power plants, and in particular relates to a combined heat, electricity and water system and a production process suitable for large pressurized water reactor nuclear power units. Background technique [0002] The technical safety and reliability of pressurized water reactor nuclear power units have been fully verified. At present, the pressurized water reactor nuclear power unit mainly generates electricity in China, and assists in providing a small amount of hot water to the urban hot water pipe network for heating residents. Due to the low steam parameters of PWR nuclear power units, there is no precedent in the field of industrial steam supply by nuclear power units. It is necessary to explore technical solutions for the technical transformation of PWR nuclear power units to produce industrial steam. [0003] Conventional cogeneration has achieved success in thermal ...
