Nuclear
power in Chinna: Daya Bay Nuclear Power Station
Most of mainland China's electricity is produced from fossil
fuels (80% from coal, 2% from oil, 1% from gas in 2006) and hydropower (15%).
Mainland China has 14 nuclear power reactors in operation, more than 25
under construction, and more about to start construction soon.

Technology has been drawn from France Canada and Russia, with local development based
largely on the French element. The latest technology acquisition has been from
the USA (via Westinghouse, owned by Japan's Toshiba) and France. The
Westinghouse AP1000+ is the main basis of technology used in here. The
first place our group had visited was Daya Bay Nuclear Power Station in
Guangdong.
The Daya Bay nuclear station is the third generation of
nuclear plant built in 1990s, while the one is Japan was built in late
1960s-70s and used older reactors. The Daya Bay nuclear power plant, however,
was built in the 1990s in line with IAEA's new standard.
The two reactor units
Daya Bay Nuclear power plant, also known as Guangdong Nuclear
Power Station, is located at Da Keng, Daya Bay in Shenzhen (about 45 km from
the city center), a Southern city in China and about 50 km north from Hong Kong.
After arriving at the Power Plant, Mr. "K?" ( sorry I forgot his
name) 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.
We are waiting for the presentation
After the presentation ( Khun Polgrit fr.EGAT and Mr."K")
We went to the Exhibition Room and Mr. "K" showed us the models
of the nuclear power plant and explained the working principle of Pressurized
Water Reactor (PWR).

We only got to viewing platforms around the plant to have a good look and we took a lot of pictures of the plant.
