Recently, China's own design and manufacture 100% localization rate of the first set of one million kilowatt nuclear reactor components in Shanghai recently passed the acceptance, which is China's first second-generation nuclear reactor components improved.
According to the "Xinmin Evening News" report, by the Shanghai Machine Tool Works Co., Ltd. glue stick made the first set of nuclear equipment, designed for supporting Hongyanhe Unit 1 for a 9 meters tall and weighs 138 tons of the "big drum." In this large-scale structure bulky appearance is much within the universe: the composition of this extremely sophisticated devices, precise welding cylinder has more than 12,000 precision parts!
Manufactured the equipment, called the Shanghai Electric Group focused national strategy, courage, daring and innovative products, glue gun a traditional manufacturing enterprises with innovations that improve energy level and core competitiveness of a successful case. Shanghai Machine Tool Works Co., Ltd. the first executive director of Sun Zhongfei accept the Shanghai network media, said that this pile of components within the factory, marking the key equipment for China's nuclear power reactor design and manufacturing technology is already into the world standard.
According to reports, the red along the river within the Unit 1 reactor components, the guide tube is the last of a successful research project. 4.5 m long tube with 12 guide plates, each plate there are 24 holes, totaling more than 500 welds. Oriented not only to each board position of holes to be exact the same degree, and each hole must always be aligned in different welding line, the error rate can not be more than 0.02 mm (approximately 1 / 3 of hair wire). According to Mr. Sun said, the difficulty of welding technology was difficult Zeng them in inviting foreign companies to provide technical support to the case without the fruit, the factory self-determination, and ultimately overcome this difficulty.
According to another report, the Shanghai Machine Tool Works Co., Ltd. The first of the two input 360 million yuan conversion plant will be put into use in first half of 2011, when the average annual output of 8-10 sets will form a unit of production capacity. This means that the company's reactor control rod drive mechanism components and production capacity ranks first in the world.
Shanghai Machine Tool Plant was built first in 1944, the Department of Shanghai Machine Tool (Group) Co., Ltd. subordinate units, under the Shanghai Electric (Group) Corporation, located in Shanghai Pengpu industrial zone. Mainly engaged in the gear cutting machine tools, machine tool and automatic processing lines, three categories of nuclear pressure equipment research and development, production, sales and service.
