they are completely safe and reliable, China uses the most advanced technology and the most stringent standards for the development of nuclear power, and strictly manages the entire life cycle of nuclear facilities from siting, design, construction, and operation to decommissioning. Since 1985, when the first nuclear power plant on the Chinese mainland, the Qinshan Nuclear Power Plant, began construction, China has adopted safe and reliable reactor technology, and learned from the experiences and lessons of major nuclear accidents abroad to make safety improvements. The safety performance of the units is better guaranteed. After more than 30 years, China has achieved independent design, construction and operational capability in nuclear power, and entered a new stage of safe and efficient development. China took the lead in the construction and operation of the GW-class pressurized water reactor, AP1000, using advanced passive safety systems, and the European advanced pressurized water reactor, EPR. The Hualong-1 nuclear reactor, a product of independent research and development, ranks among the highest in the world in terms of safety design. Construction of the demonstration project is being carried out in accordance with the highest quality standards, making the Hualong-1 a highlight of China's "going global" strategy. By June 2019, China had 47 nuclear power units in operation, ranking third in the world, and 11 nuclear power units under construction, ranking first in the world. The performance indicators of nuclear power units are generally good. By June 2019, the industry had operated safely and stably for more than 300 reactor-years, and there had been no incidents or accidents at or above Level 2 under the International Nuclear and Radiological Event Scale (INES). The incidence of Level 0 deviations and Level 1 anomalies had also decreased. In the comprehensive ranking of similar units of the World Association of Nuclear Operators (WANO) in recent years, operating units in China have performed above the world median for more than 80 percent of the indicators, and have reached the world advanced level for more than 70 percent of the indicators. In 2018, China led the world with 12 operating units achieving full marks in WANO composite index.
