China's first domestic nuclear power --- the successful completion of the Qinshan Nuclear Power Station has been put into operation the biggest technological transformation, at 1:45 p.m. yesterday, well into the East China power grid. This is the reporter from the nuclear group was informed of the Qinshan Nuclear Power Company.
It is reported that the Qinshan nuclear power plant 300,000 kilowatts of PWR nuclear power plant last year at 17 o'clock on the October 28 from the East China Power Grid solution out, the beginning of the tenth refueling overhaul. Qinshan Nuclear Power Company to overcome the tight time limit, task and the limited area of the site, such as difficulties in 75 days 20 hours of time to complete a total of more than 7,200 maintenance projects, including 37 major technological transformation.
The chief architect of Qinshan Nuclear Power Station, Chinese Academy of Sciences, Academy of Sciences to Ouyang said that the overhaul of the Qinshan Nuclear Power Station is put into production since the first overhaul of the most complex and technical, more nuclear power generating units will make "strong" safety, the operation will effectively extend the life span.
Qinshan Nuclear Power Xiao Jian, general manager of the company said that the technical transformation has greatly improved the reliability of the nuclear reactor operation and safety of our country's other nuclear power plant operation, maintenance and improvement of accumulated valuable experience.
Roof replacement of the reactor pressure vessel and protection of the digital transformation of the system overhaul is the most important technological transformation of the two projects. Pressure vessels, placed security of nuclear fuel reactor core components, and the new roof to replace the use of anti-stress corrosion resistance of the alloy material better, better protection of the safe operation of the reactor. Qinshan nuclear power plant protection system using analog signals in the past, this is in accordance with national laws and regulations and the latest standards for digital transformation.
