The K-3 unit of the Karachi Nuclear Power Project in Pakistan, the fourth entity to use a China-designed third-generation nuclear reactor, was successfully connected to the grid, laying solid foundations for commercial operation.

All four of the units adopting China’s Hualong One nuclear reactor are now connected to the grid and are generating electricity, China National Nuclear Corp (CNNC) said in a statement on 5 march.

The success in construction and operation of the nuclear reactors in Pakistan will make the Hualong One technology better received in the global market, especially in countries and regions participating in the Belt and Road Initiative, observers said.

As China's "calling card" for its nuclear power industry, Hualong One has become one of the most widely recognized third-generation nuclear power reactors in the market.
