The Hong Kong operator of the Daya Bay nuclear power plant has rejected accusations that it was slow in reporting a radiation leak. At a special Legislative Council meeting, lawmakers questioned whether the Hong Kong Nuclear Investment Company had the authority to report such incidents in a timely manner. The company, a subsidiary of CLP Power, is a minority partner in the joint venture with the state-owned Guangdong Nuclear Investment Company, which controls 75 per cent of the stake. 'Is the minority stake a hindrance to early reporting?' asked Democratic Party legislator Cheung Man-kwong. [Does it mean] that you could not do what you want to do?' The incident was classified as 'level one' on a scale of 0-7, and only incidents at level two or above need to be reported to the public immediately, according to the International Atomic Energy Agency. Flaws in a water pipe in the cooling system exposed workers to radiation equivalent to two chest X-rays during maintenance on one of the two reactors on October 23. But it was revealed yesterday that the Hong Kong operator was only informed of the incident four days later. The company then reported to its board of directors, including two officials from the Hong Kong Security Bureau and the Environment Bureau on November 2. It was not until Monday that the incident was made public on the company's website. Margaret Ng Ngoi-yee, a Civic Party lawmaker, asked whether the Hong Kong company could decide what the Hong Kong government and the public needed to know. Chan Siu-hung, managing director of Hong Kong Nuclear Investment, said its minority status did not affect its readiness to reflect Hong Kong people's concern about improving the notification system. 'We won't give up reflecting Hong Kong's people's demand for improving the notification system. 'In fact, we did raise the issue but we should do that with our partner and we are still waiting for their reply.' Chan's company insisted that the incident had no safety implications, but government officials in Hong Kong have also raised concerns over the delay in announcing the incident. The company was previously criticised for not reporting earlier that a fuel rod crack had occurred in the second reactor in May. 'We want the company to have quick, timely and simultaneous public release of information relating to nuclear power, and make reasonable arrangements to step up transparency,' said Lai Tung-kwok, the undersecretary for security. Lai said a review of the notification system was ongoing and findings could be ready by early next year.
