Ling Ao Unit 4 nuclear power plant enters commercial operation

Ling Ao Unit 4, the second unit of Ling Ao Phase II nuclear power plant, entered commercial operation in China on 7th August, 2011. Hitherto, Alstom has provided key equipment and services to the nuclear power plant and entered into the warranty period. After the operation of Unit 4, the Daya Bay/Ling Ao complex has become the largest nuclear power plant in the Guangdong province, with more than 50% of Chinas total units in operation. With these 2 additional 1080 MWe units, Guangdong province becomes one of the handful regions in the world with nuclear plants topping 6000 MWe in operation.

Similar to its sister unit Ling Ao Unit 3, Unit 4 also started up earlier than scheduled. Alstom and its long-established partner Dongfang Electric Corporation, Ltd (DECL) have once again joined hands in supplying turbine generator package to this important nuclear project.

Among the total 4 units in the Ling Ao nuclear power plant, Unit 4 enjoys the highest localization rate, with the main conventional island components designed by Alstom and supplied in partnership with DECL. The key components include GIGATOP 4 pole turbogenerator, Moisture Separator Reheater (MSR), the Condenser and the Low Pressure (LP) heater, and most of all, Alstoms ARABELLE(*) half-speed steam turbine, which is renowned for its compatibility with all reactor types, high efficiency, extended design lifetime, short overhaul periods, and low maintenance costs.

Alstoms ARABELLE technology has been widely applied to the prestigious nuclear projects in China, such as Hongyanhe, Ningde, Fuqing and Fangjiashan, as well as at Taishan, Chinas first EPR project.

As a leading supplier for Chinas nuclear industry, Alstoms presence in Chinas nuclear energy market dates back to more than 20 years. Partnering with DECL, Alstom has been involved in most of Chinas major nuclear projects by supplying close to 50% of conventional islands. The smooth and proven cooperation between the two parties ensured success in the Chinese nuclear market.

The successful start-up of Unit 4 represents a significant milestone for the Ling Ao project, for which Alstom is very proud as one of the key participants. Alstoms superior technology and know-how, coupled with our long-term partnership with DECL, allow us to continuously contribute to Chinas cleaner energy course during the 12th Five-Year Plan period, says Patrick Ledermann, Senior Vice President of Alstoms Nuclear Business.
