The study of applicability of nuclear fuel material isotopic composition measurement method based on photonuclear reaction on identifying HEU was studied in this paper. The principle of PFRR method was validated by Kimura et. al. [1] by assuming a Gaussian photon source while in this paper, Bremsstrahlung induced photon source spectrum was used.
