Summary

In March, 2001 at the Joint Research Center in Ispra Italy, a measurement program was implemented by the Institut de Radioprotection et de Sûreté nucléaire (IRSN), Fontenay-Aux-Roses, France, for the nondestructive analysis of special nuclear material held by the Joint Research. Staff of IRSN and ORTEC measured and analyzed well-characterized uranium and plutonium samples. Three of the software programs evaluated were, GammaVision (Version 5.1),[1] Program ISOTOPIC (Version 2.0.4),[2]. and PC/FRAM (Version 2.3).[3] The GammaVision evaluation determined if the peak areas were adequately determined. ISOTOPIC used modeling to compute correction factors for attenuation and geometry to determine gram quantities of each nuclide. PC/FRAM was used to determine “ISOTOPIC ratios” or weight percent of the plutonium isotopes. Samples were analyzed as unknowns and the average uncertainties determined for homogenous material consisting of: UO2, U3O8, PuO2 and MOX. Several nonhomogeneous samples were prepared in order to simulate containers of radioactive waste. Results of these measurements are presented. Information from this exercise was used to determine accuracy estimates for inspection teams who would use these methods to measure and analyze uranium and plutonium samples of similar composition at French nuclear sites.
