About the nuclear power station
The Daya Bay Nuclear Power Station is the nation’s first large-scale commercial nuclear power station. It is also one of the earliest, largest and most successful joint venture projects since the reform and opening up of the Mainland.
The station produces approximately 15 billion kWh of electricity per year. To ensure that more non-carbon and cost-competitive energy is provided to Hong Kong, Daya Bay increases its electricity supply to Hong Kong from 70% to around 80% of its output starting from late 2014, meeting a quarter of Hong Kong’s electricity needs.
Benefits of nuclear power
Nuclear power is non-carbon emitting with no other air emissions. It is safe, reliable, cost-competitive with stable supply, making it an important part in the fuel mix.
Safety excellence and emergency preparedness
At Daya Bay Nuclear Power Station, Defence-in-depth principles are used to ensure robust safety back up support. Over the years, Daya Bay has always maintained excellent performances in plant reliability, operation and safety. It has always ranked high in the World Association of Nuclear Operators (WANO)'s performance indices across major aspects of generation capability, plant safety and efficiency, industrial safety and radiation protection.
Site selection
Daya Bay is located in a seismically stable region. The site was selected according to international guidelines and stringent safety assessment by the National Nuclear Safety Administration.
Plant design
The design of nuclear power station to allow for natural hazards such as tsunami or earthquake is tailor made for the local situation around the site.
Operational safety
In the event of an emergency due to equipment failure or human error, our auxiliary equipment will step in to maintain the safe operation of the plant.
Emergency preparedness
We have well-established contingency plans at Daya Bay. Communication mechanism is also in place to facilitate communication in the unlikely event of a nuclear accident.
Comprehensive environmental monitoring
To safeguard the health of its staff and the general public, Daya Bay has a comprehensive monitoring system in place to monitor its radiation impact during operation both within the site and in the surrounding environment. Regular checks over the years show that:
- There has been no excessive or undue release of radioactivity; and
- The effect of radioactive releases on the environment is very low if not negligible.
