How to go from nuclear power to nuclear power

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.
