How can nuclear power help our country's energy structure green and low carbon transformation?

How can modern information technology enable nuclear power plant construction?

When it comes to energy saving and carbon reduction in the construction phase, Liaoning Xudabu nuclear Power Plant also has a say. At present, the 3 and 4 units of the Xudabu nuclear Power Plant are at the peak of construction. Kesong, general manager of CNNC Xudapu Project, introduced that during the project construction process, the design and construction team continued to promote technology, process and equipment innovation, vigorously carried out smart site construction, and focused on promoting "modular construction" to create "smart" projects.

Curzon said: "The construction of a nuclear power plant is a very complex and ambitious project, requiring the coordination of many professional and technical work, and in order to ensure safety, strict standards must be carried out." Now the civil construction including the later installation and commissioning stage is very different from before. We have built a smart project management platform of the project department, using modern information technologies such as the Internet of Things, artificial intelligence, BIM and big data to improve the digitization, visualization, wisdom and fine management level of the project construction process, so as to achieve real-time monitoring and control of project safety, quality, progress, cost and important on-site construction links."

It is understood that after the 3 and 4 units of the Xudabu nuclear power plant are put into use, the annual power generation is expected to reach 18 billion KWH or more, which is equivalent to an annual saving of about 6 million tons of coal and an annual reduction of 16 million tons of carbon dioxide emissions.

How can nuclear energy contribute to the construction of a new energy system?

Gao Bin, scientific and technological leader of China Nuclear Strategic Planning Research Institute, introduced that carbon emissions in the energy sector are one of the main sources of carbon dioxide emissions in China, of which the power industry accounts for 41% of carbon emissions in the entire energy sector. Therefore, it is particularly important to promote the revolution of energy consumption and production, accelerate the transformation of energy structure, and build a clean, low-carbon, safe and efficient modern energy system to achieve the "double carbon" goal.

Gao Bin said: "Nuclear power generation process does not produce greenhouse gas emissions, a million kilowatt-level nuclear power unit annual generation of nearly 8 billion KWH, compared with the same grade of coal-fired units, equivalent to reduce carbon dioxide emissions of 6.4 million tons." Compared from the life-cycle carbon emission intensity of different power supply varieties, the carbon emission intensity of nuclear power generation is comparable to hydropower and wind power, lower than photovoltaic power generation, and nuclear power generation does not produce sulfur dioxide, nitrogen oxides and other air pollutants, clean and low-carbon advantages are very obvious."

Gao Bin said that nuclear power has advantages in safety, efficiency and stability, and ensures a safe and stable supply of energy and electricity through coordination with renewable energy. In addition, in addition to the production of electricity, nuclear energy can also realize the comprehensive application of urban heating, industrial steam supply, seawater desalination, nuclear energy hydrogen production and other scenarios, providing important support for the low-carbon transformation of China's energy structure.

"With the continuous advancement of the construction of China's new power system, the proportion of new energy such as scenery in China's power system continues to rise." Nuclear power can bear the base load of the power grid, with the advantages of continuous and stable power supply, nuclear power and new energy such as scenery complement each other, coordinated development, can effectively support large-scale new energy online consumption, in the construction of new energy as the main body of the new power system to play a greater role. Nuclear energy can also be used for multiple purposes and multiple scenarios. For example, we have realized nuclear heating around Qinshan and Haiyang nuclear power bases. Tianwan Nuclear Power Plant is building China's first industrial use of nuclear energy steam supply project. In the future, nuclear energy can also be coupled with high-energy-consuming industries such as petrochemicals and steel to provide clean energy alternatives for high-energy-consuming industries. In the future, the value of clean, low-carbon, safe and efficient nuclear energy will be further highlighted, and it will better help China achieve its' dual-carbon 'goal." Gao Bin said.
