The multi-purpose development of nuclear energy has broad prospects
Large "scenery" base long-distance transmission, if it can be matched with nuclear power as a stable support power supply, long-distance transmission will not appear no-load or low-load operation. While saving energy and reducing emissions, nuclear power can also provide strong support for the "scenery" that cannot be scheduled.
Haiyang nuclear energy heating and waste heat desalination, as well as Rongcheng High temperature gas cooled reactor demonstration project waste heat utilization, etc., show that the multi-purpose development of nuclear energy has broad prospects. In addition, if the use of nuclear energy to produce hydrogen, than electrolytic hydrogen, natural gas hydrogen production efficiency, but also reduce carbon emissions. Once the economy of the multi-purpose development of nuclear energy is improved, its scale and standardized development will gradually improve, and then give full play to its potential and further improve its economy.
The economy of third-generation nuclear power will continue to improve
With large one-time investment in nuclear power, long construction cycle and zero emissions, the cost of third-generation nuclear power will continue to decrease with technological improvement and mass construction in the future, and the corresponding electricity price competitiveness and economy will also be improved. In addition, China's nuclear power itself should run with base load, but in the past few years, some units have decreased the number of power generation hours. In the past two years, the state has paid special attention to this issue, coupled with changes in the electricity market, nuclear power has gradually realized base-load operation, and its economy and role have been guaranteed.
Nuclear power itself is the attribute of power generation, if the full generation, then heating, hydrogen production and seawater desalination may be more economical, but also to further highlight the comprehensive utilization of nuclear energy competitiveness and market prospects. In addition, all parties are currently developing newer technologies such as small reactors and high temperature gas cooled reactors, and with technological progress, heating and steam supply can be achieved around the city. Therefore, nuclear power will certainly play an increasing role in achieving the goal of carbon peak and carbon neutrality in the future.
Nuclear power development needs both safety and economy
According to the "China Nuclear Energy Development Report (2020)" released by the China Nuclear Energy Industry Association last year, it is expected that in the "14th Five-Year Plan" and the medium and long term, China is expected to continue to steadily promote the construction of nuclear power at the pace of 6-8 units per year. For China's economic volume and electricity demand, nuclear power generation in the future will only rise to about 10%-15%, but such construction capacity and speed is also the world's leading.
Safety is the lifeline of nuclear power, under the premise of safety, nuclear power development must be economical. At the end of the last century and the beginning of this century, the economy of nuclear power needed to be improved, and Westinghouse continuously refined optimization from construction, manufacturing, operation and maintenance costs to improve the economy of nuclear power.
At present, we are seeing initial results in China's AP1000 nuclear power project. Economy is a test for the entire nuclear power supply chain and follow-up service chain, and China's nuclear power industry chain will continue to help nuclear power projects achieve economic improvement.
Efficient and comprehensive utilization of nuclear energy remains a long and arduous task
To achieve the goal of carbon peak and carbon neutrality, nuclear energy and its comprehensive utilization are very important. On the one hand, we will continue to vigorously develop a new generation of nuclear power technology to continuously improve safety and reduce emissions. On the other hand, nuclear energy is used for heating. With the development of technology, especially the maturity of the fourth-generation nuclear energy system technology, nuclear energy heating and seawater desalination will play a greater role in the sustainable development of energy and water security.
The comprehensive utilization of nuclear energy has a very important strategic significance for carbon peak and carbon neutrality, and is a key field for the country to achieve sustainable development of energy strategy. It is necessary to formulate scientific planning, increase investment, and strive to promote scientific research and industrialization in related fields. The use of high temperature gas cooling to produce hydrogen is of great significance to replace fossil fuel hydrogen production, but these are still at the forefront of scientific and technological development, there are a large number of technical and industrial problems to be solved, and national policies are required to vigorously promote the efficient and comprehensive utilization of nuclear energy.
The "China solution" to nuclear power will help reduce carbon emissions
Nuclear fusion is of great significance to future energy security and the development of human society, but its economy does not have many advantages at present, so our country innovatively put forward the "Chinese plan" of nuclear energy utilization.
Nuclear fusion is highly safe, highly sustainable, uses more than 90% of nuclear fuel, produces very little nuclear waste and is environmentally friendly. If nuclear fusion can be achieved, then the entire fusion, fission, mixing reactor can be used by human society.
China has always attached importance to technological breakthroughs in the field of nuclear fusion, and has made great investments. At present, China is expected to achieve innovative solutions for the utilization of nuclear energy in China, if it can achieve comprehensive utilization in urban construction, cogeneration and other aspects, it will be of great benefit to the realization of carbon reduction goals.
It is hoped that the policy will give more support to nuclear heating
Last year, the country's first nuclear commercial heating project in Haiyang nuclear power plant for the first time, the first phase of the project is 700,000 square meters. This winter, Haiyang will usher in 4.5 million square meters of nuclear heating area, which means that Haiyang city will achieve full coverage of "zero carbon" heating, Haiyang will become the country's first "zero carbon" heating city.
Nuclear heating has been supported by the guidance of national ministries and local governments, and the next need for enterprises to "draw a blueprint to the end" and plan nuclear heating regional programs in advance. It is hoped that the policy will give more support to the price of nuclear heating and encourage more enterprises to actively participate. At the same time, it also calls on more scientific research institutions and equipment manufacturers to jointly improve the scientific nature of nuclear heating, in order to promote more "zero carbon" experience.
Nuclear technology has a wide range of applications
Nuclear technology holds great promise for energy conservation, as it modifies molecules to produce better materials. For example, when applied to automobile tires, it can not only save 20% rubber, but also extend the life of the tire. It has a wide range of application scenarios in industry, agriculture, energy and so on.
If the relevant technology can solve the energy storage problem, then the "scenery" problem will be solved. Solar photovoltaic panels can be installed on the roof of each home to generate electricity, and self-sufficiency can also achieve surplus electricity Internet access. At the same time, nuclear technology can also be applied to carbon capture and storage technology, as well as big data, blockchain, artificial intelligence and other cutting-edge technology cross-combination fields. Therefore, if you effectively use nuclear technology and related resources to maximize energy efficiency, you can really help to achieve the goal of carbon peak and carbon neutrality.
The multi-purpose development of nuclear energy has ushered in an opportunity
On July 13, CNNC's Hainan Changjiang Multi-purpose modular small reactor technology demonstration project officially started at the Hainan Changjiang Nuclear Power Plant site. At this point, the project has become the world's first onshore commercial modular small reactor started.
Different from traditional nuclear power technology, modular SMR technology has the characteristics of miniaturization, modularity, integration and passivity, high safety, short construction cycle and flexible deployment, and can be used as a clean distributed energy, which can meet various uses such as seawater desalination, district heating and cooling, and industrial heating while supplying power. It is suitable for parks, islands, mining areas, high energy consumption enterprises and other scenarios. In addition to Linglong No. 1, CNNC is also targeting winter heating in the three North, North China, Northwest and other places. Under the goal of reaching the peak of carbon and carbon neutrality, the multi-purpose development of nuclear energy has ushered in a development opportunity.
The comprehensive utilization of nuclear energy is on the rise
The key to achieving the goal of carbon peaking and carbon neutrality is the green and low-carbon development of energy, and the most urgent task at present is to accelerate scientific and technological innovation. Nuclear energy is a safe and efficient clean energy, and the nuclear energy utilization industry is a high-tech industry, playing an irreplaceable role in the energy transformation. In the past decade, the state has determined the policy of actively and orderly development of nuclear power under the premise of safety, while the comprehensive utilization of nuclear energy in heating, industrial steam, seawater desalination and other fields is on the rise.
In the future, with large pressurized water reactor as a large base load, the comprehensive utilization of large-scale power generation, industrial steam, seawater desalination, heating and cooling, large-scale hydrogen production and other terminal energy products will be formed, supplemented by "landscape storage", to provide smart energy solutions, which will help Yantai City accelerate the realization of carbon peak and carbon neutrality.
