| Pressure stabilizer |
| The pressure stabilizer is important equipment to control the primary line pressure and make overpressure protection. Its main function covers: pressure control is to control the pressure variation within the specified scope in the course of system operation; water level regulation is to make up RCP system’s the change of water volume serving as the buffering tank for primary line coolant; Overpressure protection: involve in the startup of reactor and reactor shutdown regulation, that is, enable the step-up of RCP system when starting the reactor, and step-down of RCP system when stopping the reactor; it is attached with the function of degassing. |

300MW nuclear unit steam generator |
HEC (QHD) Heavy Equipment Company Limited |

|
|
| 300MW nuclear unit steam generator |
The chief function of 300MW nuclear unit steam generator is to serve as heat exchanger transferring the heat in primary line coolant to the feedwater of secondary line, enabling to generate saturated steam to drive the power unit in the secondary line. The coolant flowed from the reactor go through the hot pipe in primary line and enter into the inlet pipe of the lower gland of the steam generator and then into water chamber, flow within the reversal U-shaped tube bundle. The outer surface of the reversal U-shaped tube is in contact with the feedwater of the secondary line, enabling the gasification of the secondary line. This way, the heat exchange between primary and secondary line is made. Two steam generator for each unit.
300MW nuclear unit steam generator is vertical U-shaped tube one with natural circulation. It is 17.5m in height, 3m in diameter. Its main components are consisted of upper and lower gland, tube plate, U-shaped tube bundle, steam-water separator and cylinder etc. |

The high-temperature gas-cooled reactor is one reactor type with sound safety assurance widely recognized in the field of the international nuclear. It has perfect inherent safety, which will bring no harm to the public in the case of accident. Economically, it can compete with other power generation mode, as it has the merit of high power generation efficiency, single system structure and short construction duration.
The high-temperature gas-cooled reactor evaporator is in use of cellular spiral tube construction, vertical layout, and it is consisted of 19 heat exchange units.
Purpose: power generation, high parameter steam supply etc. The very-high-temperature gas-cooled reactor with high parameter can be used in aquathermolysis hydrogen production, coal gasification and cracking etc. |

|
| AP1000 non-dynamic residual heat removal exchanger |
| Non-dynamic residual heat removal exchanger is the equipment to discharge the AP1000 nuclear island non-dynamic residual heat. When there occurs non-LOCA accident, it is used to discharge the reactor core residual heat in emergency. Non-dynamic residual heat removal exchanger inlet piping is connected with RCS heat pipe, while its outlet piping connected with the cold chamber of the lower gland, constituting one loop for natural circulation. |

|
|
| AP1000 reactor core make-up water tank |
| Reactor core make-up water tank is one vertical cylindrical carbon steel vessel lined with stainless steel with hemispherical upper and lower glands, serving as the equipment to discharge the non-dynamic residual heat of AP1000 nuclear island. When there occurs non-LOCA accident, in case the normal make-up water is not available or insufficient, Reactor core make-up water tank will provide make-up and boronizing for the RCS. |

|
| AP1000 steam generator |
AP1000 nuclear series equipment is use of Generation III nuclear technology introduced from America Westinghouse Corporation.
Steam generator is one of the main equipment for nuclear island, whose function is to make heat exchange between primary line coolant and secondary line feedwater, and transfer the nuclear reaction heat of the reactor core to the feedwater of the secondary line, and generate saturated steam. Steam generator is the hub to connect primary line with secondary line. Tube plate and U-shaped tube constitutes part of the primary coolant’s pressure boundary of the reactor, serving as the separative enclosure to separate the medium in the primary and secondary side.
AP1000 nuclear reactor type is use of U-shaped steam generator, two steam generator for each unit. |
