ANP PROJECT QUARTERLY PROGRESS REPORT 15 e ANALYTICAL STUDIES OF REACTOR MATERIALS C. D. Susano Analytical Chemistry Division C. R. Baldock Stable Isotope Research and Production Division An empirical volumetric method for the determination of zirconium in reactor fuels has been developed. The method is based on the measurement of the basicity produced by the reaction between zirconium hydroxide and excess p o t a s s i u m f 1 u o r i d e . An i n d i r e c t volumetric method for the determination of zirconium, which depends oc precipitating zirconium as the slightly soluble benzoate or m-nitrobenzoate and subsequently determining the organic acid by titration, proved unsatisfactory because of the variable composition of the precipitate. Attempts to determine zirconiuni by titrating zirconium m-nitrobenzoate in nonaqueous media with perchloric acid were not successful. The use of mandelic acid as a precipitant for zirconium in the presence of a large excess of uranium was shown to be superior to phenyl ar sonic acid, m-nitrobenzoic acid, and cinnamic acid. The stability of the chromium comp 1 ex with diphenyl c arb az i d e was increased by development of the complex in 0.2 N perchloric acid. The separation of traces of aluminum in reactor fuels by means of anionic-exchange resins was studied; preliminary results indicate that this technique is feasible. A billiography of recent literature on bromine trifluoride as a reagent for the determinationof oxygen in metallic oxides has been started. An improved apparatus for the deterniination of trace amounts of water in solids was designed and fabricated for measuring the electrical conductivity of anhydrous hydrogen fluoride to determine its water concentration. 190 J. M. Warde Metallurgy Division In addition to the chemical analyses, various compounds of interest were examined by spectrographic or petrographic techniques . The useful - ness of the spectrograph has been enhanced by the construction of a source that is good for temperatures approaching 2850°C. The petrographic studies have led to the classification of many complex compounds that are not found in the literature. ‘[he work of the ANP Analytical Laboratory service group consisted chiefly of analyses of beryllium- and zj rconium-bearing fluoride mixtures. A review of the methods used and a summary of the services performed are included. CHEMICAL ANALYSIS OF REACTOR FUELS J. C. White J. E. Lee, Jr. C. M. Boyd W. J. Ross C. K. Talbott Analytic a1 Chemistry Division The research and developmental work on methods for the analysis of reactor fuels and their components has been of a diversified nature during this quarter. The pr iniary interest has been in the development of a volumetric method for the determination of zirconium. Other problems that have been studied include: the colorimetric determination of chromium; the determination of oxygen in metallic oxides; the separation and determination of traces of aluminum in reactor fuels; the determination of water in components of reactor fuels; the design of apparatus that w i l l permit the measurement of the conductivity of liquid hydrofluoric acid so that
