China Begins Construction Of 5 Nuclear Plants For 2009

Mercredi, avril 29th, 2009
China begins construction of its planned five nuclear power stations in the eastern and southern regions this year, the country’s energy planner  announced in  in Beijing.

The locations of the five projects will be in the coastal Zhejiang province, Shandong Province and southern Guangdong and Hainan provinces, the National Energy Administration (NEA) announced at a meeting on nuclear power application.

The construction of the Sanmen Nuclear Power Plant in Zhejiang has already begun Sunday (Apr  19).

It would be the first third-generation pressurized water reactor in the country using AP 1000 technologies developed by US-based Westinghouse, and also the first in the world using such technologies.

The first generating unit with a capacity of 1.25 million kw was expected to start operation in 2013. The plant will eventually have six such units.

« We will build more generating units with AP 1000 technologies and introduce them to inland provinces based on the construction and operation of the Sanmen project, » said Sun Qin, vice head of NEA.

The first three inland nuclear power plants in Hubei, Hunan and Jiangxi provinces were likely to get approval for construction by the end of this year or early next year, the administration said.

The other two of  the five projects scheduled for 2009, the Shandong Rongcheng Nuclear Power Plant, will begin its construction phase in September.

The project, with a generating capacity of 200,000 kW, will be domestically-designed and equipped with some fourth-generation nuclear reactor technologies, according to the NEA.

China’s mainland currently has 11 nuclear reactors at six plants, all on the east coast, with a combined installed capacity of 9.07 million kW.

Of the 11 reactors, three use domestic technologies, two are equipped with Russian technology and four with French technologies, and two are Canadian designed. All the 11 reactors employ second-generation nuclear power technologies.

To meet its economic growth, the country planned to have 40 million kW of installed nuclear capacity on its mainland by 2020, which would be 4 percent of projected electricity supply capacity, or double the current level.

Westinghouse Electric Co.’s  work  on the first  AP1000 nuclear plant on the island of Sanmen, China,  is under a 2007 contract signed by Westinghouse, its partner The Shaw Group Inc., China’s State Nuclear Power Technology Corp. and Sanmen Nuclear Power Co. of China National Nuclear Corp.

The plant is expected to begin generating electricity in 2013, according to a statement from Westinghouse.

China South Africa : Nuclear reactor technology

Jeudi, avril 2nd, 2009

China and South Africa have been steadily increasing their bilateral economic relations. However, the combination of one developed country pairing with a developing one does not involve a lop-sided partnership, but remains mutually beneficial to both. China has granted aid for infrastructure development, set up companies, sent technical manpower and helped South Africa advance, in return for access to its raw materials, oil and energy sources. Lasting relationships are built on the foundation of strong economic fundamentals.

China and South Africa have signed a Memorandum of Understanding that will enable cooperation between the two countries to develop the pebble bed nuclear reactor technology. China has the technical expertise required for building the pebble bed nuclear reactor, having built its own in 2000, which became fully operational in 2003. Now China’s Institute of Nuclear and New Energy Technology of Tsinghua University is working in collaboration with Pebble Bed Modular Reactor Pty Ltd of South Africa. PBMR technology was originally developed in Germany and was later licensed to both China and South Africa. The two nations further developed the concept though in diverse ways. Nonetheless, the commitment of both is to develop efficient and clean nuclear power, to be able to eventually ease out coal power generation, which is environmentally harmful and expensive as well. The CEO of Pebble Bed Modular Reactor, Jaco Kriek stated that though the technical approach of the two projects was different, the fundamental basis remained the same, that is, to use high temperature, gas cooled reactors using pebble fuel to get the best, reliable, clean and sustainable sources of energy. Pebble bed technology was going to overtake other power sources as it offers smart grid solutions for electricity, steam solutions for petrochemical projects, and high temperature hydrogen production.

Countries all over the world to meet their extensive energy requirements are tapping alternative sources of energy, and pebble bed technology is being increasingly rated as one safe alternative. Pebble fuel is being used as a heat source in both China and South Africa though the technology is different. The first commercial scale plant in China (HTR-PM) uses indirect cycle, steam turbine systems, while the South African PBMR is developing a direct cycle gas turbine system.
