Hualong No. 1 Domestic First ACP1000 Steam Generator Successfully Passed Hydrostatic Test

In News by administrator

At 11:50 pm on November 25th, 2016, the first hydraulic pressure test of ACP1000 steam generator made in China was successfully completed by Dongfang Electric (Guangzhou) Heavy Machinery Co., Ltd. This node marks the “China Dragon Group’s own intellectual property rights reactor type” Hua Longyi. No. “The end of the manufacturing process for the first nuclear island master equipment. The steam generator is the key equipment for energy transfer in the primary and secondary circuits of nuclear islands and is the second barrier for nuclear power plant nuclear safety. Under the witness of the Nuclear Safety Bureau North China Railway Station, Fuqing Owner, nuclear power plant, engineering company leaders and supervision and manufacturing representatives, the test has undergone the work pressure, design pressure and test pressure test as stipulated in the technical documents in order to meet the technical specifications. The first and second side hydrostatic pressure tests were passed once.

The “Hualong I” steam generator is the advanced concept of the nuclear power generation technology that has been widely adopted by CNNC in the second generation of improved nuclear power station steam generator design. It has made a number of major technological improvements, and its safety indicators and technical performance have been achieved. The advanced level of the international three-generation nuclear power technology has complete independent intellectual property rights.

Dongfang Electric (Guangzhou) Heavy Machinery Co., Ltd. undertook the manufacturing task of the “Hualong-1” steam generator. In order to overcome technical difficulties, the “Hualong-1” steam generator research group was set up, and the deep hole processing of the tube sheet was conquered. , Tube supporting plate Plum hole broaching process, tube bundles and support plates and other internal assembly processes, closing the gap heat treatment anti-DING and other technical difficulties, the final completion of the steam generator.

The success of the Hualong No. 1 steam generator water pressure test will speed up the construction of the CNNC demonstration project and signify that China’s nuclear power is steadily moving toward the world.
