Key pump valve technology to enhance China's assault nuclear localization

"Go buy some nuclear-related corporate stock in China!" Areva insiders told jokes half jokingly. Notha recently officially announced that Areva Group, which won the bid for the construction of China's nuclear power station, is one of the oldest cooperative partners in China's nuclear power plant construction. However, they now have to face a new situation. According to the national "Eleventh Five-Year Plan", by 2020, the localization of nuclear power equipment in China will need to reach more than 70%. This is how much pressure again Areva people. "A key point of domestication of nuclear power plant equipment is that you can save money." A veteran of China's nuclear industry told reporters that at present, they are studying the reliability of technology transfer of foreign enterprises and the reliability of domestic equipment. It is estimated that under the national nuclear power development plan, China-made nuclear power equipment will usher in a market of 360 billion yuan. Spring belongs to domestic nuclear power equipment two years ago to mention nuclear power "localization of equipment" seems impossible. Xu Yong (pseudonym), a sales manager of a Sino-Japanese joint venture nuclear equipment company in Jiangsu Province, has been running between the few nuclear power plants in China all year round. "At that time, I just wanted to be able to sell the pipes we produced to Qinshan Nuclear Power Station. However, they eventually Choose a foreign-made equipment, think it is more secure. "Xu Yong said the latest rules will allow their business usher in a harvest period. "National Nuclear Power Development Plan" shows that by 2020, China will strive to increase the installed capacity of nuclear power operation from the current 9.068 million kilowatts to 40 million kilowatts, and eventually build 20 nuclear power plants. These nuclear power plants will fully adopt the most advanced third generation nuclear power technology in the world. According to the plan, the proportion of nuclear power in China's total installed capacity of power will be raised from less than 2% to 4% now, and the estimated total investment will reach 450 billion yuan. "At present, 450 billion yuan of construction investment will be 70% to 80% of the share of Chinese enterprises, after all, this market is nearly 360 billion yuan." Fu Manchang, secretary-general of the Chinese Institute of Nuclear Science and Technology disclosed that "the future of domestic equipment difficult to enter the nuclear power plant Will be greatly improved under the national plan. "It is understood that some important nuclear power plants originally produced by Chinese enterprises have recently been exported to South Korea. "The huge market for nuclear power construction will drive our nuclear power equipment manufacturing industry and the subsequent export of nuclear power equipment will be one of the plans for the future," Fu Manchang said. It is reported that in the domestic construction of large-scale nuclear power plant orders, only qualified enterprises in order to participate in the certification. $$ Div $$ There is a huge cost of construction behind the plan. A nuclear equipment manufacturer in Jiangsu told the reporter: "If you use locally made equipment or a joint-venture nuclear equipment, the price may be cheaper than the direct purchase of imported equipment by nearly 40% It is understood that the price of some imported components is several times the price of domestic components. "The construction cost of nuclear power plants will directly affect the cost of power generation of nuclear power plants and how to reduce costs so that the country's nuclear power development plan can be implemented, which is a must in our industry." The aforementioned nuclear industry veteran said. Areva also agree with this view, in his view, the initial cost of generating nuclear power plant is very alarming. If you can reduce costs in the early stage, will substantially reduce the price of nuclear power. It is understood that the cost of nuclear power plant mainly from the previous investment in the construction costs, and the cost of nuclear raw materials is only one-tenth of the cost of electricity. If the initial investment into the cost, the initial cost of nuclear power plants will be much higher than the cost of thermal power, which is difficult to promote one of the reasons nuclear power projects. According to the French nuclear power plant construction plan, with the loan amounting to 42% of the total investment, the annual debt of the nuclear power plant in the initial stage of construction is 1.8 times of the annual income, which in turn leads to very high electricity price cost. "Only after 20 years of operation will the price of nuclear power plant show its superiority." According to the sources, "the electricity price will drop to 0.3 yuan at this time." According to informed sources, construction of China's nuclear power plants will reach 70% 80% of the costs need to finance the community. At present, if the construction costs are taken into account, China's new nuclear power plant generating costs will be at a very high level, the current thermal power is expected to double the price. The fourth generation of autonomous nuclear power technology still needs time Domesticization of nuclear power equipment is an inevitable general direction, but the domestic equipment manufacturers in a short period of time to create a standard equipment is a problem. In response, Fu Man Chang said that Chinese enterprises are fully capable of producing components in line with the standards and regulations. At the same time, a foreign nuclear power company explained to reporters: "There are problems with the safety and stability of the equipment produced by Chinese enterprises, which is one of the reasons why many Chinese nuclear power plants used to adopt imported equipment in the past." To this person, To large-scale development of nuclear power equipment localization is an inevitable trend, but he believes that can not blindly localization. It seems that the decision-makers in China's nuclear power have also realized this issue. Nuclear power producers with state-owned assets are making every effort to speed up their entry into the industry. However, the security of technology transfer, but also so that decision-makers are a big headache. By the end of 2006, the United States Westinghouse Consortium officially won the bid for the construction of China's third-generation nuclear power station. Subsequently, China National Nuclear Technology Co., Ltd. and the United States Westinghouse Jointly signed the third generation of nuclear power technology transfer and nuclear island equipment procurement contract in Beijing. Four AP1000 units will be introduced from Westinghouse Electric Company in the United States. The transfer of technologies includes core technologies such as AP1000 main pump technology, AP1000 burst valve technology, containment technology, pressure vessel, steam generator, integrated head sealing technology and operation management technology . Had been excluded Areva greatly stimulated. According to outside reports, some Chinese officials told Areva not to completely exclude Areva from the "Great Leap Forward" of China's nuclear power. Sure enough, Areva won eight billion euros of civil nuclear cooperation agreements on the occasion of French President Nicolas Sarkozy's visit to China in November 2007. The huge amount is also unprecedented on the global civilian nuclear market. At this moment, China and the nuclear power planning once again entered the stage of "experimental field", that is, allowing Westinghouse AP1000 technology, France EPR technology and Qinshan Nuclear Power Station's third generation nuclear power technology to compete on the same stage for a long time, with a view to effect. It is understood that Areva and the Guangdong Nuclear Power Group's specific business contract is still under negotiation. In the field of nuclear power is still the third generation of nuclear power technology discussion, the fourth generation of independent research and development of nuclear power technology has been Chinese researchers into the calendar, "around 2035." Senior nuclear experts Wang Naiyan said. Small data "National Nuclear Power Development Plan" shows that by 2020, China will strive to increase the installed capacity of nuclear power operation from the current 9.068 million kilowatts to 40 million kilowatts, and eventually build 20 nuclear power plants. These nuclear power plants will fully adopt the most advanced third generation nuclear power technology in the world. At present, China's nuclear power construction, using Areva France, Westinghouse and Qinshan third-generation technology on the same stage competitive mode.

Laminate Flooring

Laminate flooring is mainly made of high density fiber board,pressed on top the decor paper to imitate the wood design and wear layer on top to make sure it has good performance of anti-scratch.With cheaper cost,laminate flooring is popular with global customers.

The important thing to remember is laminate is thick and tough, not like plastic-based flooring that you can score and snap with a knife, so you`ll need powered saw and should be comfortable using one.
