Meanwhile, Mitsubishi Heavy Industries (MHI) has completed construction of a new plant at its Takasago Machinery Works in Hyogo prefecture dedicated to production of steam turbine rotors for nuclear power plants.

The company said the new plant will play a key role for MHI's advanced pressurized water reactors (APWRs) for the US and European markets by producing one of the world's largest nuclear power plant turbines, featuring 70-inch (1.8 metre) class turbine blades.
 
The new plant will boost MHI's annual rotor production capacity from the current six to ten and significantly push forward the company's plan to establish a "two NPPs per year" production structure. A plant dedicated to processing 70-inch class forged turbine blades is scheduled to be completed within the current fiscal year.
 
MHI has so far manufactured and supplied turbines for all 24 PWR units in operation or under construction in Japan. The company has also received export orders for turbines for nuclear power plants, including from China, Spain and Slovenia.
 

The contract, worth some ¥10 billion ($110 million), was placed by China Guangdong Nuclear Power Holding Corp (CGNPC), which is constructing the two CPR1000 units in Guangdong province. The first delivery under the contract is scheduled to be in April 2011. The first of the two 1000 MWe, Chinese-designed pressurized water reactors (PWRs) is set to start operating in 2013.

 

In July 2007, Mitsubishi Electric received an order for six digital I&C systems for CPR1000-type units from China Nuclear Power Engineering Corp (CNPEC), an engineering subsidiary of CGNPC. At that time, Mitsubishi Electric and CTEC proposed the digital I&C solution based on the system applied in advanced nuclear power plants in Japan. The order was the first I&C system developed by a Japanese company for Chinese nuclear power plants.

 

Following on from previous orders, the contract for Yangjiang units 1 and 2 means that Mitsubishi Electric's digital I&C system has now been adopted in eight out of ten CPR1000-type reactors under construction in China. It also raises the possibility that the system will continue to be applied as a standard in CPR1000 plants yet to be built.

 

CGNPC owns four nuclear power reactors in operation and ten units under construction out of the total of 30 reactors currently in operation or being built in China. The company plans to construction some 20 CPR1000 units within the next decade.

 

Mitsubishi Electric said that it is seeking to further expand its digital I&C system business in cooperation with Mitsubishi Heavy Industries, Mitsubishi Corp and CTEC.
