  • THE IDA-80 MEASUREMENT EVALUATION PROGRAMME ON MASS SPECTROMETRIC ISOTOPE DILUTION ANALYSIS OF URANIUM AND PLUTONIUM - VOLUME 1 - DESIGN AND RESULTS

Abstract

An analytical measurement evaluation programme has been carried out with 33 laboratories of 15 countries or international organizations participating, under the auspices of ESARDA and and with the support of IAEA, for acquisition of basic data on the uncertainties involved in mass spectrometric isotope dilution analysis as applied to the determination of uranium and plutonium in active feed solutions of reprocessing plants. Element concentrations and isotopic compositions of all test materials were determined with high accuracy; more than 60000 analytical data were evaluated by statistical methods mainly to calculate estimates of the variances for the different uncertainty components contributing to the total uncertainty of this analytical technique. Also investigated were sample ageing, influence of fission products, spike calibration, ion fractionation, Pu-241 decay correction, minor isotope measurement and errors in data transfer. The "dried sample" technique and the"in- "in-situ" spiking method of undiluted samples of reprocessing fuel solution with 235-U - 242-Pu metal alloy spikes, were tested successfully.
