Installation has been completed from an internal reactor from the Hualong One reactor being built in unit 3 of the Karachi nuclear power plant in Pakistan. The ones for unit 2 are installed in January 2019. The units are scheduled for commercial operations respectively in 2021 and 2022.

Internal reactors are the main structures in reactor pressure vessels that have one or more functions such as supporting the core, maintaining fuel alignment, directing primary coolant flow, providing radiation shielding for reactor vessels, and guiding in-core instrumentation.
Internal installation of the reactor at Karachi 3 completed on April 4, the Chinese National Nuclear Company (CNNC) announced today. The milestone, the company said, lays a “strong foundation” for further flushing of the main set of units and the start of cold tests.
Karachi 2 and 3 are the first exports of China’s Hualong One design, with construction of unit 2 starting in 2015 and unit 3 in 2016.
In addition to the two units that are being built in Karachi, six Hualong One units are being built in China. CNNC built two units at the Fuqing plant in Fujian province, while China General Nuclear (CGN) built two units at the Fangchenggang site in Guangxi province. The four units are expected to be connected to the Chinese network this year. Construction began at a unit in Zhangzhou in Fujian last September and at Taipingling in Guangdong at the end of December.
CGN proposes to use the British version of the Hualong One design – HPR1000 – in a prospective new nuclear power plant in Bradwell, England.
