Shanghai equips in nuclear report homebred change a domain to obtain major breakthrough. Recently, study by Chinese nuclear power the designing institute is own design, Shanghai is electric the first nucleus island that company of mill of the first machine tool makes independently is crucial equipment -- Qin Shan 2 period the component inside 3 aircrew caboodle carries extend project smoothly check and accept leave factory, implementation is all and homebred change, indicating reactor of report of our country nucleus is crucial the design of equipment makes a technology reach international level.
The component inside caboodle is the core equipment of reactor of nuclear power plant, form by 10 thousand many spare partses, use nuclear class stainless steel and nickel entirely base alloy, it is collect nicety treatment, nicety solders the large facility at an organic whole. Its main function is " consolidate " , prop up and secure nuclear fuel component; "Damping " , build reasonable flow passageway to reduce reactor to shake; "Protect " , for pressure vessel " wear " on radiation protection is taken etc. The difficulty that its nicety treatment, nicety solders to be assembled with nicety depends on stainless steel plasticity be out of shape big, machine and solder to be out of shape extremely easily, the control such as quantity of the cooling quantity in cause treatment process, the stress that hold clip, cutting and solder balance of the stress in the process, all very crucial. After general assembly, in height the error of 9 meters of central drive lines inside is less than 0.2 millimeter.
Develop to accelerate nuclear cable industry, shanghai is electric 2005 the concerned nucleus report that issues the standard, war industry board piece close to recombine, implementation is high grade asset and market sale, make, the advantage assemble that scientific research develops, establish Shanghai electric factory of the first machine tool limited company. Since the company holds water, already carried on equipment of key of island of nucleus of 22 nucleuses report creates the job, include home is new the component inside all nuclear island caboodle in construction of round of 2 acting telegram that add a nucleus and the contract that control marvellous actuating device, it is nuclear power plant of hill of the Qin Dynasty, mountain bay nuclear power plant, Pakistan to just hope early or late Ma nuclear power plant offer high grade product, the project such as caboodle of caboodle of air cooling of high temperature of university of the success Tsinghua that finish, Chinese experiment fast crowd, Chinese advanced research.
Current, shanghai is electric assuming system of nuclear island, groovy island, auxiliary equipment, control 4 board piece nuclear phone equipment develops the mission, make in equipment of domestic nucleus phone whole set faculty joins with apparent put together in the enterprise and be good at, among them, marvellous actuating device of the component inside caboodle, control is made is home exclusive. First phase of marvellous actuating device of the component inside the lot that invests 310 million yuan in base of equipment of the reshipment that face harbor, control transforms a project to already built in the round, implemented the component part inside caboodle by the past " produce 1 a few years " to at present " annual produce 3 " jump litre. 2 period the project is being advanced actively at present, be expected to produce the engineering capability of marvellous actuating device of the component inside 6 caboodle, control in 2010 body year after year, those who become the island of nucleus of report of Shanghai electric nucleus that has international competition ability to create base is important form, can satisfy the need that industry of cable of our country nucleus admits basically. -- news source: International power network
