During this period, work was continued on understanding the attrition of precipitated iron catalysts and work initiated on synthesizing catalysts containing silica binders. Use of a sedigraph particle size analyzer with an ultrasonic probe provides a simple method to test the strength of catalyst agglomerates, allowing the strength comparison of silica and hematite catalysts (the former is considerably stronger). Study of Fe/silica interactions was continued. Addition of a colloidal silica precursor to calcined Fe{sub 2}O{sub 3} catalyst had no detrimental effect on reducibility of the hematite to {alpha}-Fe. XRD and electron microscopy will be used to analyze the crystal structure and types of C present in samples from long Fischer-Tropsch runs.

We present recent results obtained with GAMMASPHERE for nuclei in the A{approx}80 mass region. These studies have concentrated on a systematic study of superdeformed bands and their transitional quadrupole moments. Normally-deformed rotational bands in a series of even-even T{sub z} = 1 nuclei were also investigated to probe the possible influence of the np pairing on the structure of their yrast bands.

The purpose of this calculation note is to provide the basis forcriticality consequences for the Tank Farm Safety Analysis Report(FSAR). Criticality scenario is developed and details and description of the analysis methods are provided.

Toxicological and radiological consequences were calculated for a maximum sodium fire in the 2727-W Sodium Storage Facility. The sodium is solid and cannot leak out of the tanks. The maximum fire therefore corresponded to the maximum cross-sectional area of one tank. It was shown that release of the entire facility inventory of {sup 22}Na is insufficient to produce an appreciable effect.
