About CNNP Nuclear Power Operations Management, CNNO

China National Nuclear Operations Management (CNNO) has been a COG member since 2003. CNNO is the operator of the Qinshan Phase III (Third Qinshan) nuclear power plant situated in China’s Zhejiang Province. It is adjacent to Qinshan Phase I (Unit 1) and Qinshan Phase II (Units 2 and 3) nuclear power plants.

In 1996, Atomic Energy of Canada Limited (AECL) signed a $4-billion contract for the sale of two CANDU 6 reactors to China.

Qinshan Phase III (Units 4 and 5) use the CANDU-6 technology and are the first heavy water reactors to operate in China. Construction started in June 1998 with AECL as the general contractor. Qinshan Unit 4 began commercial operation on Dec. 31, 2002 and Qinshan 5 on July 24, 2003. Qinshan is the first CANDU-6 project to use open-top reactor building construction and the first project where commercial operation began earlier than its projected date.

Approximately one-third of all new nuclear power plant construction in the world is currently taking place in China.
