It is specialized in pumps and valves for nuclear power plants, including sales, design, engineering, manufacturing, assembly, testing and after-sales service of reactor coolant pumps and nuclear class 2 & 3 pumps and valves for nuclear islands, as well as pumps and valves for conventional islands.
SEC-KSB is certified according to ISO9001, ISO14001, OHSAS18001 and ASME Code. In addition, it has obtained the Design and Manufacturing Licenses for Civil Nuclear Safety Class 1, 2 and 3 Pumps from NNSA.
It has manufactured and delivered more than 200 sets of nuclear class and conventional pumps since it was put into operation in the end of 2011, including 4 reactor coolant pumps (RSR) for Changjiang NPP, residual heat removal pumps, condensate pumps and auxiliary pumps for AP1000 Sanmen and Haiyang projects, and charging pumps, residual heat removal pumps, low pressure injection/safety containment spray pumps, condensate pumps for HPR1000 Fuqing Unit 5.
The 6 RSRs it will provided for Zhangzhou Units 1 & 2 - China’s first HPR 1000 reactors after technology fusion are being manufactured as scheduled. It will also provide wet winding motor RCPs (ie. RUV) for CAP1400 demonstration project and the full-sized prototype of RUV completed the final qualification test in July 2019. At the same time, SEC-KSB is actively developing CAP1000/CAP1700 50Hz RUVs.
SEC-KSB aims to form its own independent technology and intellectual property, as well as internationalized procurement and manufacturing, to provide customers with complete and reliable nuclear pump and valve products.
