The nuclear level air ejector equipment developed by Xuanda industrial group passed the appraisal

"after appraisal, the nuclear level air ejector equipment developed this time not only meets the design requirements of the product, but also has larger capacity and better performance compared with the similar imported equipment used in some domestic nuclear power plants." Recently, at the nuclear power equipment appraisal meeting presided over by the China Machinery Industry Federation, the energy and mine of the Chinese Academy of Engineering

"after appraisal, the nuclear air ejector equipment developed this time not only meets the design requirements of the product, but also has larger capacity and better performance compared with the similar imported equipment that uses hydraulic pressure to exert experimental force by this testing machine used in some domestic nuclear power plants." Recently, at the nuclear power equipment appraisal meeting hosted by the China Machinery Industry Federation, ye Qizhen, a world leading R & D Technician of the Ministry of energy and mining engineering of the Chinese Academy of engineering who provided the production of new composite materials for large structures, announced that the nuclear power products developed by Xuanda industrial group in our city had passed the appraisal. This is a solid step for Xuanda to explore the nuclear power market

it is understood that in recent years, many pump and valve enterprises in our city have actively developed other nuclear power valves and supporting equipment through independent research and development, cooperative research and development, aiming at import substitution as the main direction, realizing the localization of imported valve equipment, improving the competitiveness of domestic nuclear power valves, and seizing the nuclear power market. At present, in addition to Xuanda, Shenjiang valve, Jiangnan Valve and other high-tech enterprises in our city are aiming to develop the nuclear power market

nuclear air ejector

just like the air conditioner in the room

it was learned at the appraisal meeting in Xuanda industrial group that the investment of this project exceeded 6million yuan, which lasted more than a year. Xuanda industrial group and Shanghai Nuclear Engineering Research and Design Institute formed a research and development team, and successfully developed the nuclear air ejector in cap1400 main control room. At present, the equipment has completely independent intellectual property rights, and has applied for a number of technical patents

in the subsequent equipment test demonstration, more than 30 relevant experts from all over the country analyzed the simulated use and use effect of the equipment on site. Gehonghui, deputy chief engineer of Shanghai Nuclear Engineering Research and Design Institute, who participated in the research and development, said, "the cap1400 nuclear level air ejector we designed and developed is the key equipment of the emergency system in the main control room of the nuclear power plant, just like the air conditioner in the room, to ensure the residence requirements of the personnel in the main control room within 72 hours in the event of an accident or power failure in the nuclear power plant."

Ye Qizhen said after the experiment: "at this stage, some domestic nuclear power plants rely on imports for similar equipment, and the product developed by Xuanda has reached the use demand of nuclear power plants, filled the domestic gap, and surpassed the imported products in technical indicators, reaching the international leading level, with good social and economic benefits and promotion and application prospects."

set up a nuclear power equipment research and development center

from the research and development of equipment in the field of nuclear power to the technological upgrading of nuclear grade special valves, Wenzhou local valve enterprises with technological innovation as the core competitiveness of enterprises are taking pump and valve as the leading industry and making a cross-border transformation to the field of nuclear power equipment

"in the field of nuclear power equipment, Xuanda has carried out research and development and iteration of nuclear grade air ejectors, and continuously carried out product technological innovation on special alloy valves to meet the application needs of nuclear power development." In the view of Ye Jixuan, chairman of Xuanda industrial group, nuclear power is an important national development strategy in clean energy. The "going global" of nuclear power technology in the future is also an opportunity for enterprises to transform and upgrade themselves

it is understood that as a provincial high-tech industrialization demonstration enterprise, Xuanda industrial group has taken nuclear power as a key pass in 6 cities and focused on the transformation and development fields of the top 10 new material industry chains according to local conditions. At present, the annual R & D investment of the enterprise in nuclear power technology has exceeded 5% of the annual output value. On the basis of the establishment of Xuanda group's nuclear power equipment R & D center, the new R & D building of Xuanda group, which the enterprise has invested 30million yuan, is also about to be completed

Wenqi nuclear power products fill the domestic gap

recently, the pump and valve Research Institute of Lanzhou University of technology hosted the "China (Wenzhou) pump and valve development forum". The experts of China Guangdong Nuclear Engineering Co., Ltd. at the meeting said that China attaches great importance to the development of clean energy such as nuclear power. In China's energy structure adjustment, nuclear power has always been placed high hopes, which brings considerable market space to the domestic nuclear power valve market. According to the 13th five year plan of China's nuclear power, by 2020, the installed capacity of nuclear power operation will reach 58million kW, and more than 30million kW are under construction. To achieve the target of 88million kW of total installed capacity in operation and under construction on time, at least 6 units will be started every year during the 13th Five Year Plan period

recently, the reheat valve group of the steam turbine generator unit of the megawatt nuclear power plant, which was jointly developed by our City Jiangnan Valve Co., Ltd. and Shanghai steam turbine plant, appeared in the second military civilian integration development high-tech achievements exhibition and became the focus of attention. Academician Ye Qizhen said that this product has filled the domestic gap, and its main performance indicators have reached the international advanced level. It will change the long-term dependence on imports of nuclear power reheat valve group products, and promote the independent research and development level of China's nuclear power supporting equipment

Shenjiang valve is the second enterprise in our city to obtain the production license of nuclear power valves. Its electric ball valves and gate valves have been used in many nuclear power plants. The relevant person in charge of Shenjiang valve said that the competition in the pump and valve industry is becoming increasingly fierce. Enterprises must show their unique skills in order to stand out from thousands of enterprises and become bigger and stronger. The nuclear power valve with extremely high technical threshold is a "touchstone". Through this test, the design and development ability and quality assurance ability of the enterprise are self-evident, and it is natural to win the market initiative. It is understood that the nuclear fuel repair system jointly developed by the company and Shanghai Nuclear Engineering Design Institute is almost odorless, filling the domestic gap, and the products are even exported and applied to Pakistan Chashma nuclear power station.
