　　Applications

　　Nuclear Steam Generator for Export

　　Product supplied: Alloy 800 Steam Generator U Tube for Nuclear Power

　　Description： Jiuli is the first Chinese manufacturer who has successfully manufactured alloy 800 steam generator U tube according to the international specification requirements from end-users and designers.

　　Nuclear Fuel Cladding Tube and Hexagonal Tube

　　Description: Nuclear fuel cladding tube is the first barrier against the nuclear leak accidents and the key material for reload cycle extension and economic operation. The stainless steel nuclear fuel cladding tube and hexagonal tube independently developed and produced by Jiuli with good tolerance are proved good performance by all type of testing and actual applications.

　　AP1000 Nuclear Power Plant

　　Product supplied: Alloy 690 Steam Generator U Tube for Nuclear PowerHeat Transfer C-Tubing (Passive Residual Heat Removal Heat Exchanger)

　　               非能动余热排出热交换器用C形传热管

　　Description: 1 .Alloy 690 U tube is a key component in the third-generation of nuclear steam generator. The alloy 690 U tube for nuclear steam generator of CAP1400 which was jointly researched and developed by Jiuli and National Nuclear Power Shanghai Nuclear Engineering Research and Design Institute has been successfully used in nuclear power units.

　2. Heat transfer C-tubing used in passive residual heat removal heat exchanger is characterized by great difficulties in production. The heat transfer C-tubing being successfully manufactured by Jiuli in China for the first time is a milestone in the third-generation passive nuclear power plants. Passive residual heat removal heat exchanger is the key equipment in large scale advanced pressurized water reactors.

　　ITER Nuclear Fusion Project

　　Product supplied: PF Jacket Pipe for ITER Nuclear Fusion Units

　　Description: PF jacket round-square pipe is the key component of “International Thermonuclear Experimental Reactor” (ITER). After the tests, the properties of the PF jacket round-square pipes produced by Jiuli satisfy all DA technical specifications, and it has a great elongation at 4.2K low temperature.
