Security Bureau's response to Guangdong Nuclear Power Station incident

     In response to media enquiries on a Guangdong Nuclear Power Station incident, a Security Bureau spokesperson made the following reply:

     Upon receipt of an enquiry from Radio Free Asia (RFA) yesterday afternoon (June 14) concerning an incident that occurred on May 23 at the Guangdong Nuclear Power Station, the Security Bureau immediately sought information from CLP Power Hong Kong Ltd (CLP).

     We understand that CLP has made the following response regarding the enquiry:-

* On May 23, 2010, a small increase in radioactivity (radioactive iodine and noble gases) was observed in the reactor cooling water at Unit 2 of Daya Bay nuclear power plant. The level of radioactivity thereat has since then remained stable in the last two weeks, without any material change.

* Preliminary assessment indicates that there was a very small leakage at a fuel rod. A dedicated task group has been following up and monitoring the situation.

* The reactor cooling water is sealed in completely and isolated from the external environment, thus causing no impact to the public.

* Since the above increase in radioactivity is small, the operation of Daya Bay nuclear power plant has not been affected. The situation was below the rating for the International Nuclear Event Scale.

     Since the incident did not have any impact on nuclear safety, no immediate notification was required in accordance with the existing notification mechanism. The Security Bureau will continue to liaise with CLP to seek further information and follow up on the matter.

     The Hong Kong Observatory has set up a Radiation Monitoring Network (RMN) consisting of 10 radiation monitoring stations to monitor environmental radiation levels. The RMN measurement has not shown any abnormality between May 23 and June 13.
