China National Nuclear Corp (CNNC) said its Tianwan nuclear power station, the biggest-ever joint project between China and Russia, began full commercial operation yesterday.

Located in Lianyungang, in East China's Jiangsu Province, the Tianwan station has two generating units with an installed capacity of 1,060 MW each.

The first unit began operating in May and has since produced 4.66 KW-hours of electricity.
