Primary study on holdup measurement of 235 U in pipe using γ-ray spectrometry and Monte Carlo simulation 1 corresp first-author E-mail: wulunqiang@163.com E-mail: wulunqiang@163.com wulunqiang@163.com 1 1 1 China Academy of Engineering Physics, Mianyang 621900, China China Academy of Engineering Physics, Mianyang 621900, China The pipe holdup measurement is very important for decommissioning nuclear facilities and nuclear-material control and accounting. The absolute detection efficiencies ( ε sp ) of full-energy γ rays peak under different source density distribution function have been simulated using the Monte Carlo (MC) software, and the counting rates ( n 0 ) of the characteristic γ rays have been measured using the γ spectrometer followed by the calculation of the holdup. The holdup is affected by the energy of γ rays, distance at which they are detected, pipe material, thickness, and source distribution of pipe, especially source distribution at a short distance. The comparative test of 235 U reference materials on the inner wall of Fe and Al pipes (the total mass of 235 U is 44.6 mg and 222.8 mg, respectively) have been accomplished using this method. The determined result of 235 U is 43.2mg ( U 0.95rel =5.4%) and 216.2mg ( U 0.95rel =3.2%), respectively, which are in accordance with the reference values.
