Concrete mix design criteria, based on existing theories of proportioning and specifically oriented toward the solution of radiation shielding problems, were developed. Effects of aggregate gradation, cement-to- aggregate ratio, and water content were examined. A barytes concrete, designed according to these criteria, was thoroughly investigated in the Lid Tank Shielding Facility. Relative effectivenesses of dry aggregates, aggregates plus cement, and cured concrete were compared through thermal-neutron flux, fast- neutron dose, and gamma-ray dose measurements behind slab configurations. Attenuation was measured for the aggregate, the aggregate plus cement, and for the barytes concrete. Comparison with attenuations calculated on the basis of removal cross sections for the measured chemical compositions showed satisfactory agreement. (auth)

Incremental couples at 10% intervals across the U-Nb binary system were prepared and diffused. Irradiation damage of nickel single crystals bombarded with 3-Mev electrons from a Van de Graaff generator were studied by Kossel line techniques. It was concluded that most defects anneal out below room temperature and all anneal out below 400 deg C. The cold-rolled texture of tantaium is described by (200) and (110) pole figures. This texture may be approximated by the ideal orientations, {112} <011>, {100{ <011>, and {111} <112>. The directionality of Young's modulus, yield strength, and tensile strengih of tantalum is also presented. The effects of thermal gradients on the transformation kinetics and diffusion in U--10 wt.% Mo were investigated. The alloy U(Fe,Mn) was found to be paramagnetic from 480 to 10 deg K. The remanent magnetization of hematite along particular directions in the (111) plane and along the STA111! direction of a rectangular prism was measured during a complete cycle of temperature chsnge between 488 and 77 deg K. The remanent-temperature relationship snd the thermal hysteresis effect were also measured. The concept of space filling was developed for presenting geometrical relationships of different crystal structures. The structure of the pseudo-binary system ReTi/sub 2/--TiSi/sub …
