en.Wedoany.com Report on Mar 23rd, Recently, the KSB Group officially announced that it has secured a nuclear reactor coolant pump (RCP) order worth €150 million (approximately RMB 1.18 billion), marking the largest single order in the group's history. This order is for a nuclear power project in Eastern Europe. Due to confidentiality agreements, the specific project name has not been disclosed. The products are eight reactor main coolant pumps (nuclear RCPs), each weighing over 100 tons with a power output of 8MW, which are core equipment for the primary circuit of a pressurized water reactor.
The scope of the order includes equipment manufacturing, primary circuit safety testing, and delivery. All production will be carried out at the group's headquarters factory in Frankenthal, Germany, with delivery scheduled over the next several years in batches. These eight nuclear RCPs correspond to two million-kilowatt-class pressurized water reactor units, with each reactor configured with four main pumps. They serve as core supporting equipment for the new nuclear power project in Eastern Europe.
The nuclear RCP is the sole rotating equipment in the primary circuit of a nuclear power plant, directly determining the operational safety and thermal efficiency of the reactor. The technological barriers for third-generation nuclear RCPs are extremely high, with only a few companies globally possessing the supply capability, such as KSB, Hitachi, Mitsubishi, and China's SEC-KSB. KSB's nuclear RCP technology covers mainstream third-generation pressurized water reactor models, including Hualong One, Guohe One, CAP1000/1400, and the European EPR. SEC-KSB, a joint venture established by KSB and Shanghai Electric, serves as a core manufacturing base for nuclear RCPs in China. It has already achieved batch supply for projects like Hualong One and Guohe One, with its technology and manufacturing system fully aligned with KSB's global standards.
This order sends a clear signal of Europe's nuclear power revival. Following the Russia-Ukraine conflict, Europe, aiming for energy independence and decarbonization, is accelerating the process of restarting and building new nuclear power plants. Eastern European countries such as Poland, the Czech Republic, Hungary, and Romania have all introduced nuclear power plans. The construction of third-generation units has entered a phase of concentrated equipment procurement, and orders for key components like nuclear RCPs will continue to be released.
From a corporate strategy perspective, this order provides dual support for KSB's performance and technological barriers. The €150 million order value accounts for 5%–8% of its 2025 revenue, securing core production capacity for the next 3–5 years. The realization of this order further consolidates KSB's leadership position in the global nuclear RCP and power plant pump sectors, laying a market foundation for European SMR projects and subsequent new nuclear power unit orders. Simultaneously, the European order will drive supply chain synergy with SEC-KSB in China, enhancing the efficiency of its global manufacturing network.
The global nuclear RCP market is highly concentrated. Major players include KSB (European and Chinese markets), Hitachi (Japanese and U.S. markets), Mitsubishi (Japanese market), China's SEC-KSB, and Shenyang Blower Works Group. This substantial order further widens the technological and market gap between KSB and other European pump manufacturers like Sulzer and Flowserve in the nuclear main pump sector, strengthening its dominant position within the European nuclear power supply chain.
This order is not only a milestone for KSB's global nuclear power business but also confirms that Europe's third-generation nuclear power has entered the engineering implementation phase. The demand for core equipment such as nuclear-grade pumps and valves is on an upward trajectory, and the competitive landscape of the global nuclear power equipment market will further concentrate towards leading enterprises.
