On 5 January 2008 (Sat), Young Member Section of IMechE Hong Kong Branch organized a site visit to Daya Bay Nuclear Power Station in Guangdong. Daya Bay Nuclear power plant, also known as Guangdong Nuclear Power Station, is located at Da Keng, Daya Bay, about 45 km from the city centre of Shenzhen, and about 50 km north from Hong Kong. It was a nice sunny day and 38 participants joined this visit. In this visit, we are honoured to have Mr. Richard Fung, engineer of Hong Kong Nuclear Investment Company Limited and Ms. Annie Tong, our tour guide to give us a detailed introduction and explanation about the Daya Bay Nuclear Power Plant.

After arriving at the Power Plant, Mr. Fung gave us a presentation on the development and performance of the plant. The power station consists of two reactor units of French design Framatome 900 MW class Pressurised Water Reactors. Unit 1 and Unit 2 began commercial operation in February and May 1994 respectively. The gross power output of each unit is 984 MW. 70% of electricity generated is delivered to CLP Power Hong Kong Limited of Hong Kong and the remaining to Guangdong.

Then, Mr. Fung brought us to the Exhibition Room and showed us the models of the nuclear power plant and explained the working principle of Pressurized Water Reactor (PWR). We also visited the Training Centre and the Control Room Simulator. We also get to various viewing platforms around the plant to have a good look and we took a lot of beautiful pictures of the plant.

Our next stop was Lingao Nuclear Power Station, which is located at about 1 km northeast of Daya Bay Nuclear Power Plant. Lingao Nuclear Power Station is similar to Daya Bay Nuclear Power Plant in terms of design and equipment, and has a number of add-on technical improvement features. Having the experience of Daya Bay Nuclear Power Station, Lingao Nuclear Power Station realised the technology transfer principle and has accomplished self-reliance in design and manufacturing aspects for some parts of the equipment. Unit 1 and Unit 2 of LNPS have already begun commercial operation on 28 May 2002 and 8 January 2003 respectively. Two more units are being built and we IMechE members also has the chance to have a close look at the site work.

Before headed back to Hong Kong, We had a delicious lunch at the Expat Village, which is the accommodation for experts coming from foreign countries. The Premises was located next to a beautiful seaside and we also have the chance to have a short walk along the coast before travelling back home.

It was an educational and entertaining visit. With the help from Mr. Fung and Ms. Tong, the visit went on smoothly. Our participants also asked questions actively throughout the visit and Mr. Fung satisfied them with detailed and informative answers.

It was a precious chance to have a visit in a nuclear power plant. Members like the visit so much and this is what driving us to organise more activities for our members.
