(Yicai Global) June 18 -- Pakistan's Karachi Nuclear Power Plant, the first overseas project adopting China's home-grown third-generation Hualong One pressurized water reactor nuclear power technology, completed the engineering of its main structure yesterday.

The 366-ton dome of the K-2 unit's outer safety shell was successfully hoisted into place on the Karachi K-2 Nuclear Power Plant yesterday, online news outlet Huanqiu reported. 

The plant will conduct general and thermal testing of this security housing in the project's next phase, per the report.  

China National Nuclear contracted Pakistan's K-2 and K-3 nuclear power plant projects, and the Beijing-based company is now building four demonstration projects under construction both at home and abroad that apply the Hualong One technology.

PWRs comprise most of the world's nuclear power plants. Water in a PWR is pumped under high pressure to a reactor core where the energy released by atomic fission heats it. It then flows to a steam generator where it delivers its thermal energy to a secondary system which produces steam that flows to turbines which turn a dynamo.
