Safe and Reliable Operation of Nuclear Power Plants 

As of December 31, 2020, there were 49 units in operation on the Chinese mainland. They have been operating safely and reliably for 407 reactor years, with a good safety record. No operational events rated at level 2 or above on the International Nuclear and Radiological Event Scale have ever occurred. The radioactive effluents from the nuclear power plants in operation are far below the limits specified by the state, and the absorbed dose rate in air is within the range of local background radiation levels. Environmental monitoring shows that there has been no significant change in the ambient radiation levels around the nuclear power plants compared with pre-construction levels. In the comprehensive ranking of similar units by the World Association of Nuclear Operators (WANO) in recent years, operating units in China have performed above the world median on more than 80 percent of the indicators, and have been at the top level on more than 70 percent of the indicators. In 2020, 28 operating units earned full marks in the WANO composite index, tied for first place with 55 other units in the world.
