China National Nuclear Corporation (CNNC) said. This officially marks the start of operation “laying the foundation for subsequent grid-connected power generation and commercial operation”.

Karachi 3 is the second 1100MWe Hualong One (HPR1000) to be constructed outside China. Karachi 2 began commercial operation in May 2021. Two Hualong One units are operating in China at units 5&6 of the Fuqing nuclear plant in Fujian province. Fuqing 5 began commercial operation in January 2021and Fuqing 6, which started up in December, achieved full power on 19 February.  

As to Pakistan, five nuclear reactors provide around 8% of the country's energy mix: four CNNC-supplied CNP-300 pressurised water reactors at Chashma in Punjab, and Karachi 2.

CNNC in 2017 signed a cooperation agreement with the Pakistan Atomic Energy Commission on the construction of a Hualong One as a fifth unit at Chashma.
