Nuclear Power Plant records 15-year safe operation
By People’s Daily Online, May 07, 2009
As of May 6, Daya Bay Nuclear Power Plant, which is the first large-scale commercial nuclear power station on the Chinese mainland, has recorded 15 consecutive years of safe and stable operation. It has provided 205.12 billion kilowatt-hours accumulatively to the power grid.
In comparison with the original feasibility study report, the electricity generated at Daya Bay Nuclear Power Plant has increased from 10 billion kilowatt-hours annually to over 15 billion kilowatt-hours, and the usability ratio of the generating units has risen from 65 percent to over 90 percent.
The benefits achieved in environmental protection and resource conservation are as remarkable as the economic benefits it has achieved.
It is estimated that the electricity generated from the plant to the power grid in its 15 years of operation is equivalent to a reduction of 86 million tons of standard coal consumption, based on the conversion of the average coal consumption of conventional power plants. Moreover, it has reduced carbon dioxide emissions by 134 million tons and sulfur dioxide emissions by 33,900 tons.
In terms of the nuclear safety level, the Daya Bay Nuclear Power Station’s Unit 1 has completed five consecutive fuel cycles without any unplanned automatic reactor shutdown since January 2002, totaling 2,457 days as of May 6, 2009, which is a record in China and meets the world-class standard. It currently ranks second in safety standards among the 64 units of this type built by the Electricite De France (EDF) Group worldwide.
Statistics show that since it commenced commercial operation, the Daya Bay Nuclear Power Station has accumulatively invested over 200 million USD, digested and implemented more than 1,470 technological transformations, continuously upgraded the safety performance of its units and the professional level of its staff, and produced noticeable technological and economic benefits and social effects.
