China's Small Modular Reactor Linglong No. 1 Successfully Completes Cold Functional Test

China's small modular reactor (SMR) "Linglong No. 1" has reportedly completed its cold functional test (CFT) successfully in recent days.

China SMR Linglong No. 1.

According to state-run media outlets such as Global Times and Xinhua News Agency on the 17th, China National Nuclear Corporation (CNNC), a state-owned enterprise, announced the news regarding Linglong No. 1, which is installed in Changjiang, Hainan Province, the previous day.

The cold functional test is considered the first comprehensive health check of the entire nuclear power plant system. It is a stage that evaluates the integrity, reliability, and safety of the system before moving on to the next phase, such as the hot functional test (HFT).
