The annual power generation volume of 50 billion kWh has steadily advanced my country's ecological nuclear power construction

On September 25th, the China -Canton Nuclear Nuclear Tiaolong Ridge Nuclear Power Project Hualong -No. 2 Duke Dome was successfully completed by the China Construction Power Construction Co., Ltd. Stage steering equipment installation phase.

In recent years, as my country's nuclear power technology has become more secure, clean, and efficient, the concept of ecological nuclear power has emerged. Lian Guogang, a member of the my country Nuclear Power Standardization Technical Committee, believes that from the "nuclear power plant" to the "ecological nuclear power plant", it is not just the difference between the two words. Today, the environmental protection requirements are increasingly improved and the public has participated in the decision -making of the project widespread. Ecological nuclear power is an important measure to solve the development of the current development of nuclear power.

Guangdong Taipingling Nuclear Power is the first ecological nuclear power demonstration project in China. It is invested and constructed by China Guang Nuclear Group. The total investment of the project is estimated to be about 120 billion yuan. The plan is divided into 6 million kilowatt -class nuclear power units. Intellectual property "Hualong One" nuclear power integration technology, China Construction Power undertakes the construction tasks of the nuclear island of units 1 and 2 of Unit 1 and 2.

The "three livingism" relationship between nuclear power and natural environment, social environment, mutual life, and regeneration is the basic theory of ecological nuclear power. It requires respect and maintenance of nature as the premise to establish sustainable production methods and consumption methods. On the one hand, through the optimization and transformation of technology and facilities, the nuclear power plant has minimized the impact on the surrounding environment; on the other hand, through a reasonable design layout, the nuclear power plant can keep the surrounding natural environment as much as possible.

The dome is an important barrier to the safety of the nuclear power plant. It is an important part of ensuring the integrity and sealing of the reactor plant and achieving the inherent safety. As a result, the dome lifting is the most important milestone node for the construction of nuclear power stations. Unit 2 of the nuclear island dome is a half -opening bowl -shaped structure. The diameter of the lower mouth is 45.000 meters, the height is 13.661 meters, and the weight is 225.844 tons. The area of ​​the dome is equal to the size of the 4 standard basketball courts.

It is a big challenge to hang the dome to a high altitude of 70 meters and fall on the nuclear island tube, and the deviation control is at the millimeter level. In order to successfully complete the No. 2 nuclear island dome, China Construction Power and the China -China -Guangzhou nuclear project team carefully planned, followed up and implemented, continuously improved, and used smart nuclear power construction technology such as BIM to perform animation simulation of the lifting process in advance. In the cradle ", ensure that the dome is accurate, and a successful lifting. The project team carried out a total of more than a hundred types of work, emergency drills, dome testing, rivet workers and welders welded exercises, including large and small hanging discussions and technical intercourse. More than a hundred pieces.

Since China Construction Power participated in the construction of the first large commercial nuclear power plant in my country in 1987, it participated in the construction tasks of 11 29 nuclear power units, occupying half of my country's nuclear power construction field, and gradually built "nuclear power construction" into the company " Fist "products, and have unique competitive advantages in the field of nuclear power construction.

The construction of the nuclear island tube steel lining as scheduled is the key prerequisite for the "Hualong Coronation". During the construction process, China Construction Power vigorously carried out technological innovation. Construction of methods, replacing the industry's customary block installation and welding, accelerated the progress of steel lining, shorten the key construction path period for one and a half months, and obtained three national patents. At the same time, the steel lining modular lifting technology is also the first R & D and application in the national nuclear power field, filling the domestic technology gap.

According to statistics, the nuclear island of DV and 2 of the Taipingling Nuclear Power Project will use 130,000 tons of steel bars, and the internal structure of the nuclear island is very complicated. The project team develops a three -dimensional physical reinforcement modeling tool and application plug -in, forming its own set of nuclear power reinforced BIM samples and processing software systems. Relying on technology, it has an efficiency of 2%and is expected to save more than 1,300 million yuan.

The completion of the dome lifting is marked that the project is fully shifted from the civil construction stage to the installation stage of the equipment. It is reported that after the first phase of the nuclear power project was completed and put into operation, the annual power generation will reach 16.8 billion kilowatt -hours. After all the six machine groups in the third phase of the third phase will be completed, the annual power generation will reach 50 billion kilowatt -hours. The sustainable development of the Greater Bay Area provides clean energy, effectively improves the power supply structure of the coastal areas in the southeast, and helps the Greater Bay Area. At the same time, it is also positive for my country's "double carbon" policy.

At present, the construction of ecological civilization in my country has entered a critical period of the key strategic direction of carbon reduction as the key strategic direction, promoting pollution reduction coordination, promoting comprehensive green transformation of economic and social development, and improving the quality of ecological environment from quantity to qualitative change. Tan Jiansheng, deputy chairman of the China Energy Research Association, said that the practice of ecological nuclear power is the solemn initiative of the nuclear power industry from cleaning to ecology, from environmental integration to environmental symbiosis, which is an inevitable development direction in response to the requirements of the times.
