Qinshan Nuclear Power Plant

Active reactors ( gross ):

Reactors under construction ( gross ):

The Qinshan Nuclear Power is located in Qinshan, Haiyan county ( about 100 km southwest of Shanghai ) in Zhejiang Province in the People's Republic of China. Currently, seven blocks with 4320 MW of gross capacity in operation. Two more reactors, each with 1080 MW of gross capacity under construction, more blocks are planned.

Qinshan -1 is the only block that was not planned as a twin and built. He was almost entirely developed and built in China. Responsible was the Shanghai Nuclear Engineering Research & Design Institute ( SNERDI ). The reactor pressure vessel, however, was supplied by Mitsubishi. The reactor type was also exported to Pakistan, in order to build the nuclear power plant Chashma. The operator of Block 1 is Qinshan Nuclear Power Company.

Blocks 2 and 3, an enlarged version of Qinshan -1. The operator here is Qinshan Nuclear Power JV Corporation, Ltd. ..

History

The nuclear power plant was built in four phases.

In first phase of Qinshan reactor 1 was built with a gross output of 310 MW. Construction began on 20 March 1985. The reactor was first critically on 31 October 1991. The plant was the first designed and built in Germany nuclear power plant in China, ie more than 95 % of the components come from domestic production.

The reactor was shut down by mid-1998 for 14 months for urgent repair work.

In October 2007 Qinshan -1 shut down for a renewal for about two months, during which the entire instrument and control systems are being replaced, along with the reactor pressure vessel head and control rod drive. The work could lead to a lengthening of the duration of the original planned 30 years.

In the second phase of the Qinshan reactors were 2- 1and Qinshan 2-2 medium size of the Chinese type CNP -600 built with 650 MW. The steam generators were manufactured by Shanghai Boiler Factory in conjunction with Westinghouse. On June 2, 1996, start of construction of Qinshan 2-1, on 1 April 1997 for Qinshan 2-2 for the first time were critical on November 15, 2001 and February 25, 2004 and has focussed since April 18, 2002. May 3, 2004 are in commercial operation.

The third phase includes the construction of two reactors in the CANDU design. The reactors were developed in a joint venture with Atomic Energy of Canada Limited. This was reportedly the largest business venture between Canada and China up to this point. Construction of the two reactors of 700 MW gross power was on 8 June 1998 and September 25, 1998. Reactor Qinshan 3-1 of Qinshan reactor was posted on September 21, 2002, 3-2 on January 18, 2003 for the first time critically. Since 31 December 2002 and 27 July 2003, the two units are in commercial use. The blocks were delivered turnkey. These are the first of CANDU reactors in China. In 2010 experiments the spent fuel from normal light water reactors in Qinshan reactor were first started, 3-1 to reuse. For this, the old fuel, which still contains sufficient U235, blended with depleted uranium to produce fuel, which corresponds to natural uranium. The tests are carried out in collaboration with the Canadian CANDU developer Atomic Energy of Canada Limited ( AECL ).

The fourth construction phase continues the Phase II and expanded nuclear power plant with two more reactors of the type CNP- 600 with 650 MW. The Qinshan reactors 2-3 and 2-4 are Qinshan since 28 March 2006 and 28 January, 2007 construction. Qinshan 2-3 was connected on 1 August 2010 at the East China power grid. After a trial period of commercial operation started in October 2010. Qinshan 2-4 was connected on 25 November 2011 to the mains supply and taken into commercial operation on 30 December 2011.

Data of the reactor units

The Qinshan Nuclear Power has seven blocks in operation, and two more are under construction:
