Measurement of Total Fission Number by Delayed Neutron Method for Burst Reactor

ased on the comparison of the delayed neutron counter rate of known fission rate with the delayed neutron counter rate of a burst, a method to determine burst total fission number of burst reactor was built. The relative standard uncertainty of total fission number is 4% using BF₃ long counters as detector. The measured 30 burst total fission numbers are according with that from other methods.
