Germany's KSB Group has been awarded a contract to supply six reactor coolant pumps for use at China’s Zhangzhou nuclear plant in Fujian province, where construction of two Hualong One units is expected to begin next year.

On 15 December, SEC-KSB Nuclear Pumps & Valves announced it had been awarded a "triple-digit million euro" order from China National Nuclear Corporation (CNNC) subsidiary China Nuclear Power Engineering to supply six RSR 750-type pumps. Each pump is driven by a 10,000-volt motor with a rating of 6,600kW. A pump set (comprising pump and motor) weighs some 110t and has a maximum flow rate of about 24,500 cubic metres per hour.

The contract includes the supply of accessories, such as tools and spare parts. The pumps are scheduled to be delivered in 2020 and 2021.

SEC-KSB is a joint venture established in June 2008 between Shanghai Electric (55%) and KSB (45%). It is responsible for all of KSB's nuclear activities for pumps and valves in China, regarding sales, order processing, engineering and design, manufacturing, assembly, testing and service. The Zhangzhou NPP is being built by CNNC Guodian Zhangzhou Energy – a joint venture between CNNC and China Guodian Corp established in November 2011. The initial phase of the plant was to feature AP1000 units but will now comprise four Hualong One reactors, with two more following in Phase II.
