HTR-PM全尺寸氦循环器的耐久性试验研究

Research on the durability test of HTR-PM full-scale helium circulator

氦气循环器是HTR-PM中将氦气冷却剂从反应堆堆芯循环到蒸汽发生器的关键组件。由于没有这种循环器的工程经验,因此制作了一个完整的模型来进行测试。样机的整个参数与实际的工厂循环器相同,设计是垂直布局,其转子由主动磁轴承支撑。整个模型,包括电机和冷却器,均密封在压力容器中。由于模型是一个大型的机电系统,并且该设计包括许多新系统,因此需要进行大量测试以确保其安全性和可靠性。在核能与新能源技术研究所(INET)中建立了氦循环器工程测试设施(ETF-HC)。

Helium circulator is a critical component required for HTR-PM to circulate reactor coolant through the reactor core and steam generators.Since there is no engineering experience with this circulator,a full-scale mock-up is manufactured for tests.The whole parameters of the mock-up are as the same as the actual plant circulator for HTR-PM.The mock up design is a vertical layout with its rotor supported by active magnetic bearings.The whole mock-up including motor and cooler are sealed in a pressure vessel.Since the mock-up is a large mechanical-electrical system and the design includes many new systems,extensive tests are needed to ensure its safety and reliability.An Engineering Test Facility for Helium Circulator(ETF-HC)was then built in Institute of Nuclear and New Energy Technology(INET).
