G. A. Last reports on metallic uranium irradiation studies: cluster irradiations, tubular element irradiations, MTR-ETR irradiations on NaK capsules, effects of pH on film formation, fuel performance, effect of pressure on swelling, and ETR rupture tests. R. D. Leggett reports on irradiation program, and pore site and distribution in irradiated uranium.

The objective of this test was to irradiate self-supported fuel elements under conditions of severity comparable to those expected for future loadings of this geometry. From this irradiation an attempt was made to determine the resistance to corrosion of cooled cladding, the effect of supports on cladding corrosion and coolant flow patterns, resistance of ``hot-spot`` type of attack, and rupture resistance of projection fuel elements. These results are compared to rib supported control elements in a relative manner. To accomplish this comparison, four shortened columns of 1.47% enriched self-supported fuel were charged into B Reactor on 11-27-59, along with four columns of 1.47% enriched, current geometry fuel under authority of reference 1. As authorized, operating conditions were balanced as closely as possible within equipment and calculational limitations to minimize any ``built-in`` differences between the two materials being compared in order that exposure could be used as the basis for the rupture and corrosion comparisons.

Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Will Wilson, regarding a legal question submitted for clarification: Whether a farmer hauling livestock to market in his unlicensed trailer, returns the same livestock to his farm, would be violation of Article 6675a-2, V.C.S.

The fabrication, irradiation and evaluation of the first two superheat fuel assemblies is described in detail. Experimental data indicate that, in general, the nuclear superheat fuel elements have performed satisfactorily under the testing conditions used. Certain problem areas which will influence future fuel element designs have been defined.
