Vallourec Wins Order for Chinese Nuclear Power Plant Tubes

The fabricator will supply 1 mm thick nickel-alloy tubes for nuclear reactors Fuqing 5 and 6 to obtain its qualification for the new ACP1000 Chinese reactor design.

Vallourec (Paris, France), a world leader in premium tubular fabrication solutions, announced that its subsidiary, Valinox Nucléaire, which specializes in tubes for nuclear power plants, has won a contract to supply tubes for the Chinese nuclear reactors Fuqing 5 and 6 in the Fujian province.

In a steam generator, 1 mm thick nickel alloy tubes from Valinox Nucléaire enable thermal exchange between the pressurized water of the primary loop coming from the reactor and the steam of the secondary loop rotating the turbine. This contract represents 750 km of tubes intended for the steam generators of the plant’s two units operated by CNNC (Chinese National Nuclear Corporation).

This contract enables Valinox Nucléaire to obtain its qualification for the new Chinese reactor design, the ACP1000. By broadening its offer and experience, Vallourec will benefit from the new reactor’s potential, which will become a standard for the Chinese domestic market and for export. This third-generation pressurized water reactor, which has a capacity of 1,100 MW, was developed entirely in China by CNNC.

Nicolas de Coignac, the director in charge of the Vallourec Power business line, said, “With this new order for the Chinese nuclear market, which represents half of the worldwide nuclear market, we strengthen our global leadership in tubes for steam generators. By qualifying for the new Chinese standard, our subsidiary Valinox Nucléaire confirms its reputation for technical excellence in the critical tubes located in a plant’s primary loop, and enables us to reaffirm our determination to support our Chinese customers in their ambitious nuclear program.”

This contract comes at a time when Valinox Nucléaire, a world leader in steam generator tubes designed for nuclear power plants, has just completed its first tour around the world in tubes. Between 1974 and 2014, the wholly-owned subsidiary of Vallourec produced 40,000 km of tubes, which is the equivalent of the circumference of the earth.
