Abstract:
The safety logic channel periodic test device for high flux engineering test reactor（HFETR） was designed to detect the availability of the safety logic channel, and to find the reject-action fault of the safety logic channel. The operation principle and equipment composition of the device were introduced. The device was tested with manual and automatic modes. The effects of the test device on the logic channel were analyzed. Long-term operation practice shows that the safety logic channel periodic test device meets the test demand.
