Abstract:
Based on the principle of neutron multiplicity and data unfolding mathematics,this paper developed the software which can execute the neutron multiplicity analysis,neutron attenuation analysis,parameter calibration,Pu mass solution with the neutron pulse sequence acquisition method.The measurement system consisted of detector,nuclear electronic apparatus,pulsed sequence acquisition and analysis software was tested and calibrated by californium source.Three mental plutonium components with different mass were used for experimental assay and validation,which showed that the assay bias was within 15% against the nominal value of the samples.
