1. There are 3 locations: reaction vessel (nuclear fuel reacts here), steam generator, steam turbine
2 There are 2 loops: 1 loop (or "nuclear island") connects the reaction . The container is connected to the steam generator, and the 2nd loop (or "conventional island") connects the steam generator and the steam turbine
3 Process:
(1) THE. the cooling water from the 1st loop passes through the reaction. When it enters the container, it absorbs the heat of the nuclear reaction and the temperature increases; when it passes through the steam generator, it transfers heat to the water of the second circuit, and at the same time, the temperature decreases and returns to the reaction vessel to absorb heat again.
(2) When the water from the 2nd loop passes through the steam generator, it absorbs heat from the cooling water from the 1st loop and turns into water vapor. It then enters the turbinesteam and drives the steam. steam turbine to turn. The steam turbine drives the generator through a shaft. The rotor spins to produce electricity; After the water vapor works in the steam turbine, it turns into liquid water and returns to the steam generator to absorb heat again.
The water in the two circuits of the steam generator is always separated to ensure that the second circuit is not radioactive
"Technical regulations for water drainage systems radioactive waste from light water reactors of nuclear power plants. The standard “Technical Regulations on Radioactive Wastewater Discharge Systems from Light Water Reactor Nuclear Power Plants” applies to the design and operation of radioactive liquid effluent discharge systems from water reactor nuclear power plants light and heavy water reactor as well as the management of radioac liquid effluentstifs. dump. The Qinshan Nuclear Power Plant is the first 300,000 kilowatt pressurized water reactor nuclear power plant designed, built, operated and managed by China itself. It is located in Qinshan Town, Haiyan County, Jiaxing City, Zhejiang Province.
