The outer containment dome of Karachi Unit 2 was successfully installed on June 17.
This milestone marks the end of general construction work on Karachi Unit 2, and will be followed up by containment and heat tests.
The HPR1000 (Hualong 1), China's self-developed third-generation nuclear power technology, adopts a double containment design, with the outer containment providing protection for the primary containment.
The outer containment dome is a 366-ton multi-surface shell made up of 63 prescribed components.
CNNC has four HPR1000 units under construction around the world, which make up the world's only third-generation pressurized water reactor nuclear power project constructed according to schedule.
