X-ray fluorescence spectrometry was evaluated for the determination of glass content and homogeneity of glass incorporating high-level radioactive waste. Accuracy and precision were determined for analyses of Al/sub 2/O/sub 3/, SiO/sub 2/, CaO, TiO/sub 2/, MnO, Fe/sub 2/O/sub 3/, and NiO in specimens of known composition. These specimens were prepared by fusing powdered glass with nonradioactive synthetic waste. Matrix effects of sodium on these analyses were specifically evaluated. X-ray fluorescence spectrometry was shown to be applicable to the proposed determinations by comparing the known glass contents of 14 glass waste compositions with those calculated from experimentally determined concentrations of SiO or TiO/sub 2/.

A nondestructive technique, using penetrating x radiation, has been developed to measure the density uniformity of low-Z, compressible materials that is independent of material thickness. Thickness independence is achieved by simultaneously monitoring the transmitted and scattered x rays. Results on samples of pressed carbon materials have demonstrated that there is the expected linear relationship between measured quantities and material density, independent of material thickness, and that this is a viable means of measuring density uniformity.

The experimental efforts focused on both the development of a large aperture 2 MeV, 1A Cs/sup +/ ion beams and also a 750 kV, 60 mA Xe/sup +/ ion beams. A conceptual design and cost procedure for heavy-ion induction linacs are considered. Theoretical activities are reported on beam transport, final focusing, parameter studies, and comparison of instability theory with simulation results. (MOW)

The storage protein of maize, zein, is translated from messenger RNA on ribosomes bound to the outer membrane of the zein protein bodies. No other proteins appear to be made on this membrane. Before zein is transported through the protein body membrane it undergoes at least two post-translational modifications, which are discussed.

In order to separate the entire effect of two-particle on-shell scatterings in three-particle systems from the effects of hidden mesonic degrees of freedom (off-shell effects and three-body forces), the zero range limit of the Karlsson-Zeiger equations. Although the Faddeev equations are ambiguous in this limit, the KZ equations remain well defined. Using only two-particle phase shifts, binding energies, and reduced widths, these zero-range equations uniquely predict the three-particle observables which would occur in the absence of hidden mesonic degrees of freedom. The three-particle amplitudes possess all requisite physical symmetry properties, and can be proved to be unitary if the spectator basis is orthonormal and complete. Possible extensions of the scheme for the analysis of three-particle final states, to zero range four-particle equations, and to relativistic systems are conjectured.

The results of zircaloy cladding deformation tests in which the test parameters simulated LWR fuel rods and LOCA conditions are presented.

An administrative plan for the ZT-40 project has been developed. It describes baselines and procedures that will be used for the remainder of the construction phase of the project.
