Recently, a number of domestic nuclear power development, mediaattention, the process of the nuclear power equipment to a climax.According to statistics, as of 2005, a total of 11 nuclear powerunits in China, 900 million kilowatts, accounting for the totalinstalled power generation capacity of about 2%. Formed Qinshan,Daya Bay in Guangdong and Jiangsu Tianwan-based three nuclear powerbases. In December 2006, CPI Westinghouse signed a contract withthe United States, using its third-generation AP1000 nuclear powertechnology to build the Sanmen and Haiyang nuclear power plant.China plans to build the next 30 to 40 such units, the first unitof the valves used in all imported, and then gradually localized.Relying on specific objectives and recent projects of DalianHongyanhe nuclear power plant construction projects to achieve thenon-nuclear grade and nuclear localization of all three valves, twovalves nuclear localization rate of 80%, the nuclear level valve 70%, the fourth unit to request all domestic. July 21, 2006, theState Council approved the construction of Phase II of GuangdongLing Ao Nuclear Power Plant, Zhejiang Sanmen nuclear power plantproject. Prior to this, China has built three nuclear power basesand put into operation the nuclear power installed capacity hasreached 8.7 million kilowatts. Considerable demand for nuclearpower valve Statistics show that the existing nuclear power plantsaround the world more than 500 seats, China has built six (totalinstalled capacity of 8.7 million kilowatts). At present, Chinabegan working on advanced third-generation technology, nuclearpower plant, the project has been included in 2006's in the 10thFive-Year Plan is expected to be completed by 2020 commerciallyavailable prototype fast reactor nuclear reactions. According to"Eleventh Five-Year Nuclear Power Plan", China's nuclear power by2020 to 4% of total electricity. This means that the next tenyears, China will increase by 40 million kilowatts of nuclear powerinstalled capacity, more than 30 new nuclear power plants. China'snuclear power by 2030 to 7% of total electricity. In the "during"the start of the 12 million kilowatts and medium-sized projects,total investment will be 150 billion yuan, of which the totalamount of investment in nuclear power valves total investment ofabout 2%, then in the "during" the nuclear power plant demandexceeds the valve will be 30 billion yuan, an average annual demandof 6 billion. The nuclear power plant maintenance costs spent onthe valve have to account for more than 50% of total maintenance.From the perspective of the development of China's nuclear powerplants, nuclear power is much higher than the demand valve of thepower plant with the capacity level. With a capacity of 80 millionkilowatts of nuclear power plants, for example, diameter DN25 ~1000 cm valve demand in 8000 to 10,000 units for the same powerplant 2 to 3 times. According to statistical analysis, there aretwo sets of a million-kilowatt nuclear power plant nuclear powerplant needs 30,000 units of various types of valves, according toan annual 2.5 million kilowatts of nuclear power unit construction,the annual demand for nuclear power valve about 3.8 million units.According to the National "Eleventh Five-Year Plan" forecasts,"Eleventh Five-Year" period, the amount of demand for nuclear powerplant valve 3.0 billion, an average annual demand of 6 billion. Inaddition, because nuclear power plant maintenance costs spent onthe valve on the general maintenance of nuclear power plantsaccounted for more than 50% of the total, so the annual cost ofnuclear power plant maintenance on the valve costs about $ 150million. From this point of view, nuclear power valve market demandis quite large. Now able to independently design and manufacture ofnuclear safety is the main safety valve two, three levels of safetyvalve, globe valve, check valve, ball valve, butterfly valve, airduct valves, diaphragm valves, control valves, safety valve, thevalve diameter from 1 / 2 mm to 40 mm, pressure levels from 150 to2500 pounds (lb), materials, carbon steel, stainless steel, bodymolding methods are casting, forging, plate welding structure, thedrive has Manual, electric and pneumatic. To design, manufacturethese valve manufacturers, China has 10, including 8 to obtain thedesign, manufacture (SZ) qualification license; 2 to obtainmanufacturing (Z) license is. With China getting into the fast laneconstruction of nuclear power, nuclear power, "made of complex" hasbecome more intense. Media reports said the authorities proposedthat in the next three or four years after the completion of newnuclear power plants, nuclear localization of from 50% to 70%; moreof a hurry the view that China's "15" period will enable thedomestic nuclear power equipment, the average localization rate of75% or more. These claims give people a feeling: the localizationhas been a foregone conclusion. However, one fact has been largelyignored: China's current nuclear power equipment design andmanufacturing level, compared with the international market thereis a certain distance. Who enmesh the pace of domestic Perhaps themost telling figures. According to statistics, currently built andthe construction of 8.7 million kilowatts of nuclear power unitshave 7.2 million kilowatts respectively, from France, Canada andRussia imports, while China's independent design, independentconstruction of nuclear power plants only Qinshan a 300,000kilowatts and two Qinshan two 600,000 kilowatts nuclear powerplant. Faced with this embarrassment, the State Council LeadingGroup of experts believe that nuclear power, China's nuclear powerin the construction and operation has been able to basicallyself-oriented, but the design and manufacturing from theinternational level there are still some gaps. Autonomy andindependence necessary to purchase their own design as the coreprinciple of autonomy to run, drive equipment's autonomy. Design isa leader, not their own design, equipment manufacture localizationis undoubtedly empty, this is the first nuclear localizationthreshold, while a threshold is derived from the manufacturingsector itself. Only the valve, for example, compared with foreignand domestic valve producers, there are types of valves for nuclearpower is not enough to provide complete design level, rough piecesof production technology (such as: nuclear safety valve of caststeel on steel The chemical composition, uniformity demanding, doesnot allow slag, porosity exists), machining technology, aidedmanufacturing technologies, test techniques and test methods aregaps, we must further develop nuclear power valve products toensure product quality in order to localization of nuclear power tomeet the demand valve. From domestic nuclear power equipmentmanufacturing capability and level of business equipment point ofview, industry experts believe that China's nuclear power equipmentcompanies are not worse than abroad, foreign and some we have.However, the level of our manufacturing processes still a gaprelative to developed countries. In addition, nuclear powerequipment manufacturing standards more stringent than othermachines. China's nuclear power equipment manufacturing enterprisesin the more or less on the level of management problems,particularly in business awareness of nuclear safety is not toostrong. China's development path is a light-water nuclearpressurized water reactor, close to the third generationtechnology. At present our own design and construction of steamturbine only 65 million kilowatts, while the international advancedlevel generally reached one million kilowatts, up to 135 millionkilowatts. China is the world's eight nuclear power plants canexport country, and the removal of this honor, but is exported toPakistan in June 2000 production of 300,000 kilowatts nuclear powerplant. Obtain the production license of China's nuclear powerequipment companies are quite a few, largely state-ownedenterprises, such as a heavy, heavy, Harbin Power Group, DongfangElectric Group Shanghai Electric Group, etc., but these companiesnot many orders for nuclear power equipment, they are basically into the task to do, not do without the state. Nuclear power as anuclear power equipment buyers of domestic-oriented investment firmis not a positive attitude so that equipment manufacturers are alsohelpless. These users generally trust-made equipment is not high,and rarely consider the cost-effective, more likely to be importedfrom abroad. This has become a nuclear power equipment on the road"a stumbling block." As a result of all the fetters of the nuclearlocalization expect too easily lead to the bubble effect. Somepeople predicted that China's nuclear power industry to really, themarket will take a long time. Just enter the nuclear power industryin China is ready to accelerate the development stage, the realacceleration until after 2010. According to national authorities inplanning, by 2020, increasing China's nuclear power installedcapacity will reach 36 million to 40 million kilowatts, involvingdirect investment of 300 billion yuan. Localization rate of 60%according to the average estimate of foreign nuclear powercompanies to provide equipment and technology from the nuclearshare of 120 billion yuan in direct about this point, thelocalization rate of increase equal to the nuclear power equipmentmanufacturing companies from abroad back to grab the meat of themouth. Do is more important than that The future of nuclear powermarket a broad space for development, more contrasting China'snuclear power equipment manufacturing industry survival of thestate of distress right now. To make nuclear localization of thevalve as soon as possible, Dongfang Electric Corporation and othercompanies are building nuclear power Nansha new heavy equipmentmanufacturing base. Yantai Moon joint venture with South Koreathree letters of the joint venture has officially put intooperation. Earlier media reports, the French nuclear powerequipment manufacturing companies AREVA group met with 15 Chinesemanufacturers for a wide range of joint ventures, such ascooperation with the Dongfang Boiler manufacture nuclear powerplant steam generator, and Shanghai No.1 Machine Tool Factorymanufacturing co reaction reactor pressure vessel component,Pioneer Motor Factory and the Shanghai Cooperation manufacturingcontrol rod drive mechanism, and so on. Cooperation was verysuccessful, domestic equipment manufacturing have reached theEuropean level. From the side also reflects the quality of Chinesemanufacturing enterprises to improve. In this process, China'snuclear power equipment manufacturing companies go step by step,Ling Ao nuclear power plant equipment manufacturing of two nuclearpower plants made of the overall capacity of 30%, then 55 Qinshantwo key nuclear device 47 to achieve a localization, equipmentlocalization rate of 55%. Insiders suggested that domesticconstruction is not how to say, but rather how to do it.
