Up to 19 of China National Nuclear Corporation’s (CNNC) nuclear power units would be likely to get full marks on a 100-point evaluation by WANO (World Association of Nuclear Operators) in December 2021, according to the latest performance indicator calculation rules. A total of 22 CNNC nuclear power units met the calculation conditions of the WANO composite index, with their average index reaching a record high of 99.51 and performance reaching advanced levels.

The 19 units are:

Units 1, 2, 3 and 4 at the Qinshan No 2 nuclear power plant;

Units 1 and 2 at the Qinshan No 3 nuclear power plant;

Unit 1 at the Fangjiashan nuclear power plant;

Units 1, 2, 3 and 4 at the Tianwan nuclear power plant;

Units 1, 2, 3 and 4 at the Fuqing nuclear power plant;

Units 1 and 2 at the Changjiang nuclear power plant; and

Units 1 and 2 at the Sanmen Nuclear Power Plant.

Note: WANO indicators are a common indicator system for the global nuclear power industry, composed of 14 individual indicators and a composite index. They evaluate nuclear power plants' comprehensive performance in terms of nuclear safety, power generation management, power plant equipment reliability, and industrial safety in a quantitative manner.
