The principle of photofission reaction ratio (PFRR) method was proposed and validated by an ideal Gaussian photon source simulation previously. In this research, Bremsstrahlung spectrum photon sources were applied to the method to identify high-enrichment uranium. We have investigated the applicability of the Bremsstrahlung photons for PFRR
