During the post Japanese nuclear power accident period, China's mechanical properties provided the performance "nuclear" to "nuclear" from

it seems that China's nuclear power, once deeply depressed, has seen a glimmer of dawn. Recently, Xu Yuming, Deputy Secretary General of the China Nuclear Energy Industry Association, said at an international nuclear energy conference that during the "12th Five Year Plan" period, China's nuclear power installed capacity will reach 50million kW, and by 2020, China's nuclear power installed capacity is expected to reach 70million kW. As for whether this goal can really be achieved at that time, Xu Yuming affirmed that "it is completely possible"

affected by the Fukushima nuclear power accident in Japan, the Chinese government has suspended all new nuclear power projects for the purpose of safety inspection, and made it clear that no nuclear power projects, including those that have carried out preliminary work, shall be approved before China's nuclear safety plan is approved

the Chinese government's statement after the nuclear accident in Japan has suddenly frozen China's nuclear power construction, which has been heating up in recent years, and the construction enthusiasm that has been ignited has also been reduced to the lowest

compared with the silence of the nuclear power industry some time ago, Xu Yuming's answer this time is a positive signal. Although his remarks cannot represent the final decision of the official, at least they can reflect China's current attitude towards the development of nuclear power

how about China's attitude towards nuclear power? After the Fukushima nuclear power accident in Japan, nuclear power suppliers at home and abroad have shown great concern about the changes in China's nuclear power policy. Not long ago, it was originally a small-scale nuclear power development exchange conference, but it attracted a large number of domestic and foreign enterprises and consulting institutions to send representatives to attend. They are all speculating on the attitude of China's top management. As long as there is a glimmer of hope, they will not easily give up the market opportunity in this large nuclear power construction country

it is understood that among the nearly 60 nuclear power units under construction in the world, China has become the country with the largest scale of nuclear power under construction in the world. The annual fixed asset investment in the field of nuclear power construction is more than 70 billion yuan, with strong demand and huge market space

according to the statistics of China Electricity Council, by the end of last year, 13 nuclear power units with an installed capacity of 10.82 million KW had been put into operation in mainland China. It is also understood that at present, the national energy administration has approved the construction of 12 nuclear power projects, a total of 34 units, with a total installed capacity of 36.92 million KW, of which 24 have been started, and the rest will be completed by 2020

Xu Yuming said that with the existing nuclear power installed capacity and the nuclear power installed capacity that has been under construction and can be operated by the end of the 12th Five Year Plan, China's nuclear power installed capacity will exceed 40million kW in 2015, close to 50million kW. He further said that by 2020, with the continuous maturity and improvement of China's second-generation, second-generation improved and third-generation nuclear power units, mass production will also be accelerated. By then, China's nuclear power installed capacity will reach 70million kW to 80million kW

Xu Yuming, who once served as director of the science and Technology Bureau of China National Nuclear Industry Corporation and director of the second Department of system engineering of the Commission of science, technology and industry for national defense, has a deep industry background. To this end, his statement boosted the confidence of nuclear power builders. However, Xu Yuming also euphemistically said that the further development of nuclear power will not be clearer until the nuclear safety plan is issued

it is understood that China's nuclear safety plan has been formulated for a long time, but it has not been completed yet for various reasons. Without the nuclear safety plan, the relevant national departments cannot carry out scientific, standardized and unified supervision of nuclear power plants from the aspects of standards, regulations and supervision, and ensure the safe operation of nuclear power plants

previously, many nuclear power experts said that China's nuclear power development will not be affected by the Fukushima nuclear power accident in Japan, and the status of nuclear power will continue to be consolidated and strengthened in the future. The state has requested that the nuclear safety plan be prepared as soon as possible. It is said that the preparation time will be shortened as far as possible and will be issued as soon as possible

who will fill the power gap in the future

in recent days, the media reports about power shortages around the country have been increasing, and a variety of complex factors have made the power gap continue to increase. According to the prediction of the China Electricity Council, power supply and demand will be tight during the "12th Five Year Plan". It is worth noting that the new round of power shortage "threat" has once again pushed nuclear power to a particularly eye-catching position

relevant data show that in the first quarter of this year, the national infrastructure added 13.79 million kw of power generation capacity, 2.34 million KW less than the same period last year. "Hubei Engineering Laboratory for physical property testing technology of functional film materials" was recently established in Wuhan. Among them, thermal power increased by 10.01 million KW, but 2.68 million KW was put into operation less than the same period last year

according to statistics, during the "Eleventh Five Year Plan" period, due to the inclination of power engineering construction investment to the field of non fossil energy power generation, the completed amount of thermal power investment decreased rapidly from 227.1 billion yuan in 2005 to 131.1 billion yuan in 2010

for this reason, Wang Zhixuan, Secretary General of the China Electricity Council, warned that the current serious shortage of power supply under construction, coupled with the serious loss of thermal power and the reduction of construction enthusiasm, is likely to cause an unreasonable rapid decline in the scale of thermal power production in the next few years, which can not meet the growth of power demand. It is expected that the contradiction between power supply and demand will become more prominent during the 12th Five Year Plan period, especially in the middle of the 12th Five Year Plan period

the shortage of thermal power installation must be replaced by corresponding units, so that the "threat" of future power shortage will not really become possible. Xue Jing, director of the statistical information department of the China electricity Union, said in an interview that the China electricity union actively supports the development of nuclear power on the premise of ensuring safety. In this regard, Wang Zhixuan also said that promoting the efficient development of nuclear power will help alleviate the power shortage dilemma in the future. As a national authoritative organization in the power industry, the attitude of China Electricity Council is commendable, which may also indicate that the power industry is full of expectations for the future of nuclear power

it is understood that according to the Research Report on the 12th Five Year Plan of the power industry issued by the China Electricity Council, the power consumption of the whole society will reach 5.99 trillion ~ 6.57 trillion kwh in 2015. During the 12th Five Year Plan period, the average annual growth rate will be 7.5 ~ 9.5%, and the benchmark scheme is 6.27 trillion kwh, with an average annual growth rate of 8.5%

the goal of the power industry planning in 2015 is: the national installed power generation capacity will reach about 1437 million KW, with an average annual growth of 8.5%, including 284million kW of hydropower, 41million kW of pumped storage, 933 million kw of coal power. Finally, industry insiders said that 43 million KW of nuclear power, 30 million kw of gas power, 100million kW of wind power, 2million kW of solar power, 3million kW of biomass power and others

looking forward to the growing power demand, relevant industry insiders said that if China's nuclear power development plan is significantly reduced due to the nuclear accident in Japan, who will fill the remaining installed capacity gap? According to reports, China's nuclear power generation in 2010 accounted for about 2% of the country's total power generation, equivalent to a reduction of 25million tons of standard coal and 73million tons of carbon dioxide emissions per year. In this regard, industry insiders further pointed out that if the installed capacity of nuclear power is not increased, who will reduce the carbon emissions equivalent to three times of the current stage

energy bottleneck and emission reduction pressure

at this stage, energy conservation and emission reduction is an important task in economic development. At the end of 2009, China announced China's carbon emission reduction target, that is, "by 2020, China's carbon dioxide emissions per unit of GDP will be reduced by 40% to 50% compared with 2005, and the proportion of non fossil energy will reach about 15% in 2020"

as a binding indicator incorporated into the medium and long-term planning of national economic and social development, the proportion of carbon emission reduction and non fossil energy determines that China's power structure must be adjusted

according to the planning and research of China Electricity Council, during the "12th Five Year Plan", the total installed capacity of non fossil energy power generation will reach 474million kW, accounting for 33% of the total installed capacity, which is 6.3 percentage points higher than that in 2010; Non fossil energy power generation is about 1.52 trillion kwh, accounting for 24.1% of the total power generation, an increase of about 3 percentage points over 2010; Non fossil energy power generation can replace fossil energy by 500 million tons of standard coal, accounting for about 11.9% of primary energy consumption

in the total installed capacity of non fossil energy power generation, according to the established goal, the installed capacity of nuclear power will account for about 10%. Some experts pointed out that compared with renewable energy such as wind energy and solar energy, the advantages of nuclear energy are mainly reflected in the long-term and stable energy supply. "As a safe, clean and efficient energy, nuclear power is the most practical alternative energy to ensure the safety of energy supply, adjust the power structure and protect the ecological environment in China."

according to insiders, due to the influence of natural conditions, the instability of wind and solar power has always been an important factor restricting their development. It is estimated that the actual efficiency of wind and solar power installation is only 40% of that of thermal power

it is also understood that at present, the technologies of wind power and photovoltaic power generation in China are still developing and immature, so their construction costs are high and their economic competitiveness in the market is weak. These factors also determine that wind and solar power are difficult to become the main source of electricity in the short term

at the same time, insiders also said that although China's large-scale hydropower development has resource potential and development technology advantages, which can replace the output of some thermal power units, hydropower development also faces many problems and challenges, such as land inundation, ecological environment protection, resettlement, development difficulty, international river development and so on

in contrast, nuclear power is not restricted by region, and there are more options for construction site selection. The advantages of nuclear power will determine its important position in the future power structure

observation: choosing nuclear power

it should not be difficult for China to continue to choose nuclear power

on the premise of ensuring safety, the constraints of energy and environment, as well as the pressure of power demand, have created a good opportunity for the rapid development of nuclear power in the future

in recent years, with the sustained and rapid development of China's economy, the acceleration of industrialization and urbanization, the upgrading of residents' consumption structure, and the rapid growth of power demand, the task of power production has become very urgent

in today's high coal price, how to get rid of the restriction of high coal price on power has become the primary problem affecting the smooth operation of the economy. It is understood that China's coal production bases are mainly distributed in Shanxi, Shaanxi and the west of Inner Mongolia, while coal consumption centers are mainly distributed in the southeast coast. This supply-demand pattern directly forms the current situation of tight coal transportation with long haul distance and large volume, and leads to the continuous rise of coal prices

it is estimated that the fuel quantity of nuclear power plants with the same power is about one tenth of the weight of coal. And the nuclear power unit can be built near the load center, with significant layout advantages

in terms of cost, the development of nuclear power undoubtedly also has a high competitive advantage. According to a study by the Chinese Academy of engineering, the specific investment of Qinshan Phase II project in China is 1330 US dollars/kW, which is the lowest cost project in the world. In 2005, the electricity price was 38.5 cents/kWh, while the electricity price of the newly-built desulfurization coal-fired power plant in Zhejiang in the same period was 43 cents/kWh. Compared with renewable energy such as wind energy, the cost competitive advantage of nuclear power is more prominent

the importance of developing the nuclear power industry is also reflected in the transformation and improvement of the manufacturing capacity of nuclear power equipment. Current total production of nuclear power equipment manufacturing in China
