HPR1000（Hua-long Pressurized Reactor）is main brand of China nuclear power industry "go global" strategies. In July 27, medium-pressure safety injection pump and emergency boride pump of HPR1000, researched and developed by Chongqing Pump Industry Co.,Ltd.(CQPI) affiliated with Chongqing Machinery Electrics(Group) Co.,Ltd. (CME) independently, has passed state nuclear power experts group appraisal.
The research and development for medium-pressure safety injection pump of HPR1000 is the most difficult. Its characteristic is little tolerance and high cavitation performance, which can run flat at small flow but head decreased rapidly at large flow. Besides, emergency boride pump adopts several knowledge patents with characteristics of small vibration, low noise and stable operation.
Experts group has carried out site evaluation for running situation and index parameters of model machine, listened to summary report of CQPI and reviewed related technical documents, unanimously agreed to appraisal. The experts group has agreed that the research and development of medium-pressure safety injection pump and emergency boride pump of HPR1000 is successful. The two types of pump have reached international advanced level, filling the domestic blank, with high social and economic benefits.
