April 6, Institute of Nuclear Energy Technology, Chinese Academy of Sciences news that the advanced nuclear research team developed a new fuel assembly and cladding material, not only to solve the key technical problems of lead-based reactor core materials, but also for Other liquid metal cooling reactor fuel development to provide technical support. The nuclear reactor independent research and development technology to break the monopoly of foreign technology. In our country, in 2015, China's national installed capacity of nuclear power reached 26.43 million kilowatts, an average annual growth rate of about 17%. At present, the total nuclear power generation in China is far below the world average of 23.3%, with much room for growth. It was reported that lead-based reactors have been evaluated by GIF-4 as the fourth generation reactor expected to be the first to achieve industrial demonstration and commercial application. In addition to its outstanding advantages in terms of production safety and economy, lead-based reactors also have advanced nuclear energy "incineration" processing capability and nuclear fuel proliferation capability and are an advanced nuclear energy system capable of a wide range of applications and sustainable development. Therefore, lead-based reactor has a good industrial base, such as the Russian submarine equipped with lead-based reactor has nearly 100 reactor-year successful operation experience. Due to its huge commercial potential, the current lead-based reactor engineering applications in Russia and Europe are currently under way and commercial demonstrations are planned for 2021. At present, two low and middle-level radioactive waste disposal sites have been built and run in the country. The key equipment used in the nuclear waste disposal yard that has been built mainly depends on the import, the high price and the export control of the producing countries. Therefore, localization of equipment in the future is the trend of the times. By 2030, more than 200 active nuclear power units are expected to close in the world, with the retired market reaching nearly 100 billion U.S. dollars. Qinshan Nuclear 300,000 kilowatts generating units are expected to retire about 2025, the future civilian and military nuclear decommissioning related industries have great potential for development.
