China Valves Technology (CVVT) said that its gate and check valves used in the core island of nuclear power plants has successfully passed all tests administered by China Institute of Atomic Energy (CIAE) and Nuclear Power Institute of China (NPIC).

CIAE is the primary nuclear science and technology research institute in China and NPIC is the leading base in China for nuclear reactor engineering research, design, testing and operation.

The prototype valves, which has a diameter of 250mm and 1500lb of compressive resistance, is now eligible to be supplied for core islands of nuclear power plants.

According to National Development and Reform Commission (NDRC), China will install at least eight nuclear power generating units each year between 2010 and 2020.

Each nuclear power generating unit will require more than 30,000 valves, of which over one-third are used in the core island.
