Description: Das Projekt "Development and performence assessment of measurement systems for nuclear materials, 1992-1994" wird vom Umweltbundesamt gefördert und von European Commission, Joint Research Centre (JRC). Institute for Transuranium Elements (ITU) durchgeführt. Objective: To develop methods for the destructive analysis of the samples taken from the open fuel cycle and, in particular, from reprocessing plants. General Information: Progress to end 1991. The analytical tools for safeguards analysis were further refined and progress was made in achieving the set goal of an overall error of less than 0.1 per cent . A set-up to accelerate plutonium dissolution by applying a high frequency field (microwave) was successfully tested. The titration program was modified and extended. The data transfer between the mass spectrometer and the PDP computer was improved. Progress was made in the development of an expert system for quality assurance and error detection. An expert system for the programming of robotized sample dissolution was developed. The results of this work were summarised in 5 conference papers. Detailed description of work foreseen in 1992 (expected results). Investigations will be made to reach the goal of 0.1 per cent accuracy in critical safeguards measurements and the application of these methods to an on-site laboratory. The processes of dissolution and titration of product samples of U and Pu will be robotized for the onsite laboratory. Investigations of the error sources of the measurement of U and Pu concentrations by isotope dilution will be carried out and the results incorporated in the quality assurance program. The measurement of Pu by isotope dilution gamma spectrometry for safeguards purposes will be investigated for potential application at reprocessing plants. A portable K-edge absorption device using an isotope source for uranium products samples will be tested for its application on- site at reprocessing plants. Short description of evolution of work in 1993. Further improvement of techniques for the destructive analysis of fissile materials.
