Geophysical and geochemical models of the Earth's shields and rift zones

Description: This report summarizes a collection of, synthesis of, and speculation on the geophysical and geochemical models of the earth's stable shields and rift zones. Two basic crustal types, continental and oceanic, and two basic mantle types, stable and unstable, are described. It is pointed out that both the crust and upper mantle play a strongly interactive role with surface geological phenomena ranging from the occurrence of mountains, ocean trenches, oceanic and continental rifts to geographic dis… more

Tank study committee report

Description: Six major problem areas have surfaced in the past twenty-five years concerning the use of plutonium tankage. The most significant of these involves the use of borosilicate glass as a neutron absorber. Approximately thirty recommendations and criteria resulted from a study of these problem areas. Not all of the criteria and recommendations are unanimously supported by all members of the committee. The committee agrees that problem areas that can be handled on a short-term basis are being pursued… more

Development of optimum conditions for drying ion exchange resin in a fluidized bed dryer

Description: Drying of Amberlite IRC-72 ion exchange resin in a fluidized bed dryer was investigated. Resin water content was measured as a function of drying time for various drying temperatures, bed loadings, and air flow rates. An incomplete equation for the induction period and complete model for constant rate drying were developed. Further development of an induction period model requires installation of an accurate air flow measurement device. A drying temperature of 200/sup 0/F results in the shortes… more

Cold Dissolved Saltcake Waste Simulant Development, Preparation, and Analysis

Description: CH2M Hill Hanford Group, Inc. is identifying and developing supplemental process technologies to accelerate the Hanford tank waste cleanup mission. Bulk vitrification, containerized grout, and steam reforming are three technologies under consideration for treatment of the radioactive saltcake wastes in 68 single-shell tanks. To support development and testing of these technologies, Pacific Northwest National Laboratory (PNNL) was tasked with developing a cold dissolved saltcake simulant formula… more

Fundamental nucleon-nucleon interaction: probing exotic nuclear structure using GEANIE at LANCE/WNR

Description: The initial goal of this project was to study the in-medium nucleon-nucleon interaction by testing the fundamental theory of nuclear structure, the shell model, for nuclei between {sup 8}Zr and {sup 100}Sn. The shell model predicts that nuclei with ''magic'' (2,8,20,28,40,50, and 82) numbers of protons or neutrons form closed shells in the same fashion as noble gas atoms [may49]. A ''doubly magic'' nucleus with a closed shell of both protons and neutrons has an extremely simple structure and is… more

Investigation of in situ hydrothermal oxidative destruction of NDMA

Description: Rate constants for the aqueous oxidation of N-nitrosodimethylamine (NDMA) have been measured in aqueous phosphate-buffered solutions using Dickson-type vessels. The initial NDMA concentrations ranged from 2.5 to 2.8 ppm and reaction temperatures varied from 180 C to 220 C. Quantitation of NDMA was performed by gas chromatography-mass spectrometry (GC-MS) using selected ion monitoring (SIM). NDMA loss with concomitant production of nitrite and nitrate confirmed that mineralization of NDMA occurr… more

Computational Theory of Warm Condensed Matter

Description: We have developed an improved computational theory of condensed matter in the regime where T {le} T{sub Fermi}. Previous methods of calculating the equation of state (EOS) relied on interpolation between low-temperature (solid) and high-temperature (plasma) limits, or employed severe approximations. Recent theoretical and experimental developments have highlighted the need for accurate EOS and opacity data in the intermediate temperature range and offer the opportunity to test theoretical model… more

Edge-Spread Functions Expected for Several Changes in a Commercial Flat-Panel System

Description: The Bldg. 239 radiography facility uses a 9 MeV bremsstrahlung linac and a commercially available fiat-panel detector system. Ref. [1] discusses the facility in detail. Ref. [1] furthermore discusses the imaging quality of the fiat-panel system, and identifies several sources of image blur for the system in question. The maim'' contributors to the imaging blur are radiation scattered from the front cover of the detector housing, radiation scattered from the back cover of the detector housing, a… more

Laser materials processing applications at Lawrence Livermore National Laboratory

Description: High power and high radiance laser technologies developed at Lawrence Livermore National Laboratory (LLNL) such as copper-vapor lasers, solid-state slab lasers, dye lasers, harmonic wavelength conversion of these lasers, and fiber optic delivery systems show great promise for material processing tasks. Evaluation of models suggests significant potential for tenfold increases in welding, cutting, and drilling performance, as well as capability for applications in emerging technologies such as mi… more

Developmental requirements for canning a low density thoria demonstration load

Description: The feasibility of fabricating aluminum clad, low-density ({approximately} 65 per cent theoretical density) thoria elements using thoria produced-by a modified Sol Gel process, low frequency-low energy vibration for compaction, and the TIG welding process for closure welding has been demonstrated by Hanford Laboratories (HL). They have also assembled thoria fuel elements for the initial irradiation to produce 1 to 2 kgs. of U-233. At this time, it is expected that Hanford will be asked to produ… more

Fuel failure Lot KY-928-Q D Reactor

Description: On February 13, D Reactor sustained a bumpered enriched fuel element failure in process tube 3289. The element failed in the twenty-first position from the rear of the charge and was from lot KY-928-Q. Visual examination of the failed element indicated the failure mechanism to be cleavage of the uranium core. This conclusion was substantiated in part by the appearance of ``worm tracks`` in the aluminum jacket. The fuel failure was detected approximately three hours after the reactor had resumed… more

Process water treatment for reactor effluent activity control: Budget study

Description: The purpose of this study is to provide budgetary data for modifying and monitoring the present water treatment process at B, C, D, KE, and KW reactor plants to effect a reduction in the activity of the reactor effluent water discharged to the Columbia River. The study is subdivided into three parts: facilities for sodium silicate addition at each reactor water plant, on-plant facilities for the manufacture and supply of sodium silicate, and instrumentation for monitoring the water treatment pr… more

Infrared spectroscopy of organic free radicals related to combustion processes

Description: We will explore a variant of resonant two-photon ionization (R2PI). Development of the IR + UV R2PI experiment is underway. We have used optical R2PI and pulsed field ionization detection to obtain vibrational spectra of the benzyl and phenylsilane cations. In benzyl, we have learned about the vibronic coupling in the mixed 1{sup 2}A{sub 2}-2{sup 2}B{sub 2} system near 450 nm by projecting the mixed states onto the manifold of cation vibrational states. In phenylsilane{sup +}, we find that the … more

Results of preliminary reconnaissance trip to determine the presence of wetlands in wet forest habitats on the Island of Hawaii as part of the Hawaii Geothermal Project, October 1993

Description: In October 1993, the authors sampled soils, vegetation, and hydrology at eight sites representing a range of substrates, elevations, soil types, and plant community types within rainforest habitats on the Island of Hawaii. Their purpose was to determine whether any of these habitats were wetlands according to the 1987 Corps of Engineers Wetlands Delineation Manual. None of the rainforest habitats they sampled was wetland in its entirety. However, communities established on pahoehoe lava flows c… more
