China as a member state of the International Atomic Energy Agency (IAEA) has adopted the International Nuclear and Radiological Event Scale (INES) in reporting Licensing Operational Events (LOEs) identified in all mainland nuclear power stations. This is an internationally recognised standard that help the public, media and the nuclear community to understand the significance of nuclear events.

Public Notification Mechanism for Non-Emergency Licensing Operational Events (LOEs)

In order to enhance transparency and public understanding on the operation of the nuclear power station, both Daya Bay and Ling Ao Nuclear Power Stations have adopted a public notification mechanism to publish information of non-emergency LOEs (INES level 0 or 1, with no nuclear safety significance or consequence respectively) through the website of Daya Bay Nuclear Power Operations and Management Company (DNMC), and those of Daya Bay further at the website of Hong Kong Nuclear Investment Company Limited (HKNIC), within two working days after an event being identified.

Communication under Emergency Situation

If an emergency event (generally INES Level 2 or above) is identified which may potentially give rise to radiological consequences at the station site or the outside environment, the Daya Bay Nuclear Power Station will activate an “Emergency Response Command Centre” which will take lead in on-site emergency response, and report to relevant government authorities at Guangdong Province, which will in turn, notify its counterpart in the Hong Kong SAR Government and provide relevant information. The Chinese authorities would also meet their obligation under the International Atomic Energy Agency Convention on Early Notification of a Nuclear Accident and inform the Agency and neighbouring states.
