The self-developed million-kilowatt nuclear power plant main feed pump group successfully passed the full flow test assessment and the special assessment of cold and thermal shock tests.


On January 27, 2015, relevant leaders and experts from the Science and Technology and Progress Department of the National Energy Administration, China Machinery Industry Federation, China Nuclear Power Engineering Co., Ltd., China Nuclear Power Engineering Co., Ltd., China Central Plains Foreign Engineering Co., Ltd. and other units were at the site of our company's high-power nuclear pump testing center, jointly witnessed the special tests such as the full speed normal temperature performance test (including 30% minimum flow performance test), cold and heat shock test of the main feed pump set of the million kilowatt nuclear power plant independently developed by our company and China Nuclear Power Engineering Co., Ltd, the test values of flow, lift, power, efficiency, vibration, noise, bearing temperature, start-stop and operation of the pump unit under various working conditions all meet the requirements of the technical specifications of the main feed water pump unit of Fuqing Units 5 and 6. Among them, the thermal shock time of the pump unit and the vibration value under 30% minimum flow condition are better than the requirements of the pump unit test outline, which are unanimously recognized and praised by the experts and leaders present. The pump unit has been developed for more than 3 years. During this period, leading experts from China Nuclear Power Engineering Co., Ltd., China Nuclear Power Engineering Co., Ltd., Daya Bay Nuclear Power Operation Management Co., Ltd. and other units have provided technical support and assistance. I would like to express my heartfelt thanks.
