Operational event at Ling Ao Nuclear Power Station
The Nuclear Emergency Committee Office of the Guangdong Province notified the Security Bureau today (March 18) of an operational event at Ling Ao Nuclear Power Station (LNPS), a Security Bureau spokesperson said today.
Through a feedback review at LNPS, it was discovered that on November 27, 2024, during the replacement of the demineralizer in Unit 1's chemical and volume control system, the outlet isolation valve of the demineralizer was not closed as required. This resulted in a drop in the volume of certain liquids within the system. Station staff immediately halted the relevant operation, and the volume of the liquids promptly resumed normal. Throughout the above event, Unit 1 remained in a safe and stable condition, with all relevant parameters within normal ranges.
As this event holds certain reference and learning value, LNPS classified it as a Level 0 deviation on March 17, with a view to raising awareness among station staff and helping them learn from the experience. This deviation did not affect the safety of the Unit, the health of the workers, the nearby public or the environment. LNPS has reported the relevant situation to the nuclear safety regulatory authority and will strengthen experience feedback to ensure the safe and stable operation of its units.
The Daya Bay Nuclear Power Operations and Management Co Ltd has released the details of this event on its website (www.dnmc.com.cn) (Chinese only), which can be viewed in the "operational events" section under the "nuclear and radiation safety information" page of the website.
New control on regulated mercury-added products to take effect on December 31
The control for newly regulated mercury-added products under the newly amended Mercury Control Ordinance (Cap. 640) will take effect on December 31, 2025, covering eight newly regulated mercury-added products (see Annex).
The Government completed the amendments to the Mercury Control Ordinance in June this year to implement amendments adopted at the fourth meeting of the Conference of the Parties to the Minamata Convention on Mercury to gradually phase out mercury-added products that are harmful to human health or the environment, so as to reduce the opportunities of the public's exposure to these mercury-added products for safeguarding public health and protecting the environment.
An Environmental Protection Department (EPD) spokesman said, "Once the amendments to the Ordinance come into effect, the manufacture, import, export and supply of the relevant regulated mercury-added products will be prohibited. Anyone who contravenes the above regulations commits an offence and, upon conviction, is liable to a maximum fine of $50,000 and imprisonment for one year."
Under the new measure, the Government has set a grace period for the supply of newly regulated mercury-added products (not applicable to production, import and export of the related product) until January 2029. After the grace period, if anyone continues to supply the relevant regulated mercury-added products, the authorities will initiate prosecution after collecting sufficient evidence.
To help the trades understand the new control requirements, the EPD has earlier written to stakeholders, including importers, exporters and distributors of the concerned mercury-added products, to detail the implementation specifics of the new controls, and has conducted visits to stakeholders to provide guidance.
Relevant information has been uploaded to the EPD's dedicated website (www.epd.gov.hk/epd/english/international_conventions/mercury/mco.html). For any enquiries regarding the newly amended Mercury Control Ordinance, please contact the EPD at 2838 3111 or via email at enquiry@epd.gov.hk.
