From the beginning of 1954, the Soviet Union’s first civilian nuclear power, nuclear power in developed countries has been rapid development, especially in the 1960-1970’s, but then the United States and the Soviet Union, Chernobyl Two Three Mile Island nuclear accident has slowed the pace of development of nuclear power in the world. And as the oil climbed to a peak of $more than 100 a barrel, the development of nuclear power was revived. But in 2011, the spill in Japan’s Fukushima nuclear power plant reappeared, and some countries and regions, such as Germany and Switzerland, decided to abandon nuclear power.
Yang Hanxin, a doctor in the Department of nuclear engineering, University of Manchester, thinks that the core of nuclear waste is not only the consideration of safety, but also the factors such as slowing down of energy demand and impact of renewable energy. In fact, many countries, especially developing countries, need a lot of electricity, and it is more urgent to develop nuclear energy.
Data show that at present, there are 448 nuclear power plants in 31 countries in the world, and the total installed capacity is 400 million kilowatts, which accounts for about 10% of the world’s total electricity generating capacity, reaching 16% at the peak. At the same time, as of July 1, 2017, the construction and construction of nuclear power units are 59, 160 units, the market size is close to 1 trillion and 200 billion US dollars.
Francois Morin with a color to do a more detailed analysis and explanation. As you can see, there are 45 countries worldwide are actively considering the development of nuclear power projects, such as Argentina, Belarus, Bangladesh, Brazil, Finland, Chinese, Hungary, India, Iran, Pakistan, Romania, Britain, Russia, Slovakia, United Arab Emirates, Turkey, etc.. It is expected that by 2050, the new 1000GW nuclear power installed capacity will be added to 25% of the total power generation capacity.
China is considered to be one of the most important forces. According to the “Chinese power development” 13th Five-Year “plan” requirements, in 2020 the national nuclear power installed capacity will reach 58 million kilowatts, the construction scale of 30 million kilowatts. According to the data, as of November 2017, China (excluding the Taiwan region) has invested 37 units of the nuclear motor group, which has been put into commercial operation, and 19 units in the construction of the nuclear motor group. Nuclear power installed capacity ranked fourth in the world, generating more power than Japan, entering the top three in the world, in the construction of nuclear power units for many years in the world first.
Over the past year, China “nuclear safety law” formally promulgated, “Interim Measures for the protection of the safety of nuclear power consumption” issued, the civil engineering construction demonstration fast reactor, which is less than expected, at the beginning of the year plan started 8 units still waiting for the final approval of the three door first AP1000 reactor failed to schedule production, not even complete the loading node.
Xu Yuming, deputy director of the expert committee of the China Nuclear Energy Industry Association, believes that the development of China’s nuclear power is still in a strategic opportunity period. He analyzed that nuclear power is the only energy that can replace coal in large scale and provide stable and reliable power for grid. It is indispensable for the construction of green low-carbon energy system in China. At the same time, the proportion of nuclear power generation and power generation is very low, and there is enough room for development. It is expected that in 2030, the installed capacity of China’s nuclear power can reach 100GW to 120GW, and the power generation capacity of nuclear power is up to about 8%. After 2040, the installed capacity of China’s nuclear power plant will reach 150GW, and the proportion of power generation is close to the current world average of 11%, which is more than quadrupled now.
However, it is not to be ignored that the development of China’s nuclear power is also facing many challenges, including security, economy, independent innovation, public understanding and support. In the third generation of nuclear power construction, there is a widespread problem of delay in construction and increase in construction cost. Moreover, the relationship between supply and demand of economy and electricity has entered the new normal, and the measures such as bidding online and limiting power consumption have reduced the utilization hours of nuclear power equipment.
