Debye-Waller factors of the light actinide metals

Description: Time-of-flight neutron powder diffraction was used to determine the Debve-Waller factors of light actinide metals. The Debye-Waller factor is a measure of the mean-square atomic displacement that arises from the thermal motion ofthe atoms in any solid. Its temperature dependence determines a Debye-Waller temperature, {Theta}{sub DW}, that is characteristic of the elastic properties of the solid. The data are obtained by Rietveld analysis of neutron diffraction powder patterns obtained at severa… more

Structure and phase transformations in uranium metal

Description: In common with other elemental actinides, metallic uranium exists in several allotropic forms, differing from one another by complex but subtle atomic rearrangements. This article reviews progress in understanding the successive phase transformations from the perspective of soft-mode instabilities.

Nuclear metallurgy lectures: Chapter 1

Description: The purpose of this course is two-fold. It should serve as a review for the metallurgist of the classical metallurgical concepts applied to such metals as uranium, thorium, plutonium, and zirconium. These metals are relatively unfamiliar to the metallurgist, but the concepts are still the same ones applied to familiar metals. The second purpose is to acquaint the non-metallurgist with the reasons for selection, advantages, and disadvantages of the various fuels and structural materials used in … more

Estimation and Characterization of Decontamination and Decommissioning Solid Waste Expected From the Plutonium Finishing Plant

Description: Purpose of the study was to estimate the amounts of equipment and other materials that are candidates for removal and subsequent processing in a solid waste facility when the Hanford Plutonium Finishing Plant is decontaminated and decommissioned. (Building structure and soil are not covered.) Results indicate that {approximately}5,500 m{sup 3} of solid waste is expected to result from the decontamination and decommissioning of the Pu Finishing Plant. The breakdown of the volumes and percentages… more

Critical mass control: Continuous neptunium

Description: During April 1962, equipment in both the main Redox Building (202-S) and the Plutonium Concentration Building (233-S) vas rearranged to allow the accumulation and recovery of neptunium without interference with the production of uranium and plutonium. In order to do this, the former rework column (1S) was put into continuous service as a neptunium recovery column, the Third Plutonium Cycle was converted to a neptunium decontamination cycle, and ion-exchange equipment was installed in the 233-S … more

Critical mass control specifications: Hoods 7-C and 9-B

Description: This report discusses the critical mass control specifications for Hoods 7-C and 9-B have become obsolete due to needed storage within the confines of Hood 9-C, and equipment modifications. Nuclear safety in Hood 7-C and 9-B depends almost entirely on controlling the mass and geometry of the plutonium compounds not confined by the processing equipment. Generally, the processing vessels and associated piping are designed and arranged in the hood to be critically safe at full operating capacity. … more
