Analysis of China's nuclear power development trend and advantages and disadvantages (2)

3, the effectiveness of nuclear power. A 1 million-kilowatt nuclear power plant needs about 110 to 13 billion yuan of investment. According to the expert's on-site inspection, it is believed that the site of the furnace (general Wengyu Village) in the Xitou Town of Xiuyu District in Putian City has 6 to 12 sets of nuclear power generating units of 1 million kilowatts, which is estimated based on the construction of six million kilowatt nuclear power units. The investment will be at least 60 billion yuan. After the project is completed, it is estimated that it will bring about 1.7 billion yuan in tax revenue each year. After the project is completed, it is estimated that an additional education fee of 50 million yuan will be added each year, which can greatly improve the local educational conditions. The nuclear power project has been settled in Putian City. A huge investment will surely drive the rapid economic development of Putian City, and it will greatly promote the coastal industry of Putian City. As a complex product system, the nuclear power industry has relatively high requirements for corresponding supporting facilities. Putian City can use its own advantages to find mutually beneficial entry points for both sides, develop machinery manufacturing and service industries, seize opportunities to upgrade the industry, and promote the entire nuclear power industry. The development of the chain. For example, Haiyan County in Zhejiang Province was originally a relatively backward and poor area. After the Qinshan Nuclear Power Station was established in Haiyan County, it was a large local taxpayer every year. During the construction period, the average annual tax revenue was about 200 million yuan. By 2006, the output value of nuclear power was as high as 5 billion yuan. With a taxation of up to 800 million yuan, it has effectively promoted the development of the local economy and now ranks 34th among the top 100 counties in the country. Taking Qinshan Phase II two sets of 650,000 kilowatts nuclear power units as an example, the entire project has invested RMB 14.8 billion. Six shareholders have invested a total of RMB 2.4 billion. During the calculation period (25 years) of the project, a return of RMB 200 billion to shareholders will be given to the country. It pays 200 billion yuan in taxes, and has a repayment of 200 billion yuan, which has good economic benefits.

4, the limitations of nuclear power. Although the huge amount of investment in nuclear power projects can promote the local economic and social development, nuclear power projects have settled in the area. Given the special nature of nuclear power plants, special protections have to be restricted within different distances. The main protection areas of nuclear power plants are divided into non-residential areas and restricted areas, and also include some special protection areas. In non-residential areas with a radius of 0.5 to 1 kilometer around the reactor of a nuclear power plant, the water, soil and original features of the site shall be maintained. Except for the buildings of nuclear power plants, construction of any permanent buildings, quarrying, blasting, and deforestation shall be prohibited. Soil, building graves, etc. In a restricted area with a radius of 7 km, centered on nuclear reactors, no large-scale industrial enterprises, mining enterprises and institutions may be built, especially large-scale flammable, explosive, toxic, corrosive, radioactive and other dangerous goods manufacturing enterprises. Facilities such as transportation, pipelines and warehouses shall not build prisons, large ports and railway hubs; limit the establishment and development of various types of development zones; control the scale of new hospitals, schools, convalescence, and tourism projects; More than one concentration of resident centers. Within 16 kilometers from the site, it is not appropriate to construct the airport, including the vertical projection of the air corridor and the distance from the edge line within 4 kilometers of the site. The temperature of seawater at the outlet of a nuclear power plant was increased by 4 degrees in a range of 0.6 square kilometers, and the temperature was increased by 1 degree in a range of 8 square kilometers. According to the calculation of 6 generating sets, the new nuclear power plant requires a sea area and a land area of ​​about 4,000 mu.
