KSB’s RUV reactor coolant pump has been certified for use in China's latest generation III+ nuclear power stations.
The German pump and valve manufacturer has already received its first order to supply five of the pumps for the Shidaowan nuclear power station, where the world’s largest AP/CAP series reactor will be built. Part of the order will be manufactured at KSB headquarters in Frankenthal, Germany, and part in Shanghai, where the Shanghai Electric-KSB Nuclear Pumps & Valves Co Ltd (SEC-KSB) joint venture is based.
The RUV pump prototype has successfully passed tests in Lingang, China. According to KSB, all measured values met or exceeded the official test specifications. In total the pump set was in operation for more than 700 hours, including more than 500 hours at a temperature of over 284°C. In line with the test specifications, the pump, which has a drive rating of about 7.5 MW, was started and stopped more than 550 times. KSB says that when dismantled after testing, all components were in perfect condition.
“The successful certification is an important milestone for KSB following a development period of close to ten years,” said Dr Stephan Bross, a member of KSB’s management. “It underlines our position as a technology leader in the nuclear market. This is a good starting point for us in the growing Chinese energy market. We are expecting to receive orders that will safeguard jobs also in Germany.”
