The nuclear power plants in Daya Bay and Ling Ao continue to meet safety standards despite three minor incidents in the last 16 months, according to a safety committee that monitors the two neighbouring facilities.

Speaking to the media after an annual meeting on Thursday, committee chairman Dr Raymond Ho Chung-tai said the stations appeared to meet high safety performance standards and show “good implementation of safety and quality management”.

Hong Kong deserves role in nuclear reactor risk management, experts say

However, three minor safety incidents were reported by the two stations since the beginning of last year. An issue with a fire extinguisher caused a “below scale” (level 0) incident at Daya Bay last October.

Daya Bay, partly owned by CLP Power, provides the city with about a quarter of its electricity needs.

Two level 0 incidents occurred at Ling Ao this year. The first case, in January, involved an air vent closing unexpectedly, while the second, just last week, involved the filters of a water intake pipe being blocked by a large accumulation of small krill-like shrimp.

“The level 0 incidents carried no safety significance or impact on the environment or public safety,” Ho said.

Established in 1988, the 17-member committee advises the operators of the Daya Bay and Ling Ao nuclear power stations in Shenzhen on safety measures and reports back to the Hong Kong public.
