The peculiarity of China is that the use of hydropower as an alternative low-carbon source of energy often becomes both economically and environmentally disadvantageous. Most of the new dams are to be built in the ecologically sensitive southwestern regions.
For the population living there, the construction is becoming a big problem. Construction of dams may result in flooding of fertile land and increase the risk of flooding. As many river ecosystems have been damaged, environmentalists have called for a ban on major hydropower projects.
The country is now turning to large-scale use of renewable energy sources. Considerable investments are going into constructing solar and wind power generators, but their use is also limited. Such generators have low power, depending on weather conditions, and occupy valuable land. When deployed in the western desert regions and transmitting solar and wind power over long distances, significant losses are incurred.
Experts argue that solar and wind power can only play an auxiliary role and be used to supply urban and rural enterprises and households but will not be able to provide enough power to newly developed industrial areas. The further development of nuclear power has become economically justified.
As noted in a previous piece on the future of nuclear power, meeting the rapidly growing demand for low-carbon energy will require the rapid development of nuclear power, which should provide up to 25 percent of electricity by 2050. It means that over the next 30 years, global nuclear energy production will need to triple. Instead of declining, nuclear power production will skyrocket, and the Fukushima effect will steadily disappear. This piece focuses on the future development of nuclear power in China.
As of the end of 2020, the top three nuclear-generating countries based on installed capacity were the U.S., which produced 98.2 GW (which was 20 percent of the country's total capacity), France, 63.1 GW (70 percent of the total capacity), and China – 47.5 GW (5 percent of the total capacity).
In the previous five years, i.e., between 2016 and 2020, a total of 20 new commercial nuclear power units were commissioned with an additional installed capacity of 23.45 GW. These figures show that the volume of commissioned capacities has doubled in just five years. And it's reported that 17 nuclear power units with a total capacity of 18.53 million kilowatts are currently under construction.
According to GlobalData Plc, China will quickly rise in the rankings of the world's leading nuclear energy producers, overtaking France as the world's second nuclear power producer by 2022 and ranked first in the world by 2026.
The country must have its most modern nuclear reactors to implement such ambitious plans. In 2015, China began constructing a new block of the Fuqing nuclear power plant for the first time, based on its technologies. The historic power-up of China's first Hualong One Reactor, the result of 30 years of research and development, took place in November 2020.
Commissioned by the National Energy Administration (NEA), these reactors were jointly designed by two nuclear companies – China General Nuclear Power Group and China National Nuclear Corporation (CNNC). They solved the problem of combining two reactor designs: ACP1000 and ACPR1000, based initially on the French M310 reactor.
Thus, at the end of last year, China became the fourth country to develop its technology of third-generation nuclear reactors after the U.S., France, and Russia. This remarkable achievement means that China has broken the foreign monopoly on nuclear technology and has become one of the leading countries in this area. Each Hualong One power unit's installed capacity is about 1.2 GW, and the reactor can generate annually about 10 billion kWh of electricity per year.
One Hualong One power unit will reduce carbon dioxide emissions by 8.16 million tons and reduce carbon consumption by 3.12 million tons annually. "China is capable of mass production of its third-generation Hualong One reactor, which can be seen as China's newest business model," said CNNC chairman Wang Shoudun. Work in this direction is one of the 16 key national scientific and technical projects.
In the next 30 years, the total generated power of Chinese nuclear reactors must grow more than sevenfold. The world has never seen projects of this magnitude. It will take significant efforts from the state, scientists, engineers, and technologists to achieve such an ambitious goal. But without work on such an unprecedented scale, the global challenge of tackling climate change will not be possible.
