To meet the monitoring needs for critical accidents in places with nuclear criticality accident risk,such as reactors,nuclear power plants,spent fuel post-processing facilities,and nuclear material storage and transportation facilities,the new type of neutron critical alarm instrument based on FPGA+ARM is designed.The neutron critical alarm instrument is composed of detection device,processing and displaying unit,and a platform that can send out alarm signals through sound and light,and has monitoring functions.According to performance testing,the equivalent dose rate radiation level of this event is 1 mSv/h,and the alarm response time is less than 10 ms.The neutron criticality alarm instrument meets the design requirements and can be used for monitoring and alarming of critical accidents in places with nuclear criticality accident risk.
