Continuous-flow leach testing method for various nuclear waste forms

Description: Nuclear waste is planned to be buried in deep geological repositories. If these repositories were ever invaded by ground water, the waste form could be corroded and the nuclear waste released to the surrounding geologic medium. The rate at which this flowing ground water corrodes the waste form can be studied using the Lawrence Livermore National Laboratory's single-pass continuous-flow leaching test. This repository-relevant leaching test places the waste form of interest into a flowing stream… more

Filamentation of a converging heavy ion beam

Description: A major concern in the use of heavy ion beams as igniters in pellet fusion systems is the vulnerability of the beam to the transverse flamentation instability. The undesirable consequence of this mode is the transverse heating of the beam to the extent that convergence on the pellet becomes impossible. This work considers the case of a beam injected into a gas filled reactor vessel, where finite pulse length and propagation distance play an important role in limiting growth. Two geometries are … more

GAMIDENT: a program to aid in the identification of unknown materials by gamma-ray spectroscopy

Description: A computer code, called GAMIDENT, was written to help identify isotopes by their gamma-ray emissions and thus to assist in the non-destructive assay of unknown materials. The program searches a file (called GAMIN) of gamma-ray spectra, from both radioactive decays and neutron captures, for matches with observed photon energies. This report describes the search procedure used, outlines the use of the code, and gives examples. The code is designed for operation at the Lawrence Livermore Laborator… more

Low-cost solar array project. Task I. Silicon material: investigation of the hydrogenation of SiCl/sub 4/. Third quarterly report

Description: A laboratory stainless steel reactor has been constructed and installed to study the hydrogenation of SiCl/sub 4/, 3 SiCl/sub 4/ + 2 H/sub 2/ + Si reversible arrow 4 SiHCl/sub 3/. The reactor is designed to operate at pressure up to 500 psig which is the proposed operating pressure range of the Union Carbide EPSDU; silane-to-silicon process. Series of experiments were carried out to measure the reaction kinetics. The effect of reactor temperature on the rate of the hydrogenation of SiCl/sub 4/ … more

Nova chain design and performance

Description: During the past year design of the Nova laser has undergone significant change as a result of developments in our laser glass and optical coating evaluation programs. Two notable aspects of the glass development program deserve emphasis. First, vendor qualification for production of fluorophosphate laser glass is progressing satisfactorily. There is a reasonable expectation that vendors can meet fluorophosphate glass specifications within Nova schedule constraints. Secondly, recent gain saturat… more

Prayer and Religion in the Public Schools: What Is, and Is Not, Permitted

Description: Few areas of constitutional law have proven to be as controversial and as subject to misinterpretation as that concerning the constitutionality of government-sponsored religious activities in public schools. In the last three decades the Supreme Court in five decisions and the State arid lower Federal courts in dozens of related decisions have attempted to articulate the 1 / meaning of the religion clauses of the First ~mendment- for a variety of such activities, including State-sponsored praye… more

Precipitation and Lake-Level Changes in the West and Midwest Over the Past 10,000 to 24,000 Years. Final Report

Description: The goal of the research described in this report is to document the climatic variability over the past 10,000 to 20,000 years in areas in which sites may be designated for the burial of nuclear wastes. Three separate data sets were studied, and the results are presented in three chapters. The first data set consisted of radiocarbon dates documenting past changes in lake levels in lakes and playas in the western United States. The sites were mapped where water levels were higher than the levels… more

Program GROUPIE (version 79-1): calculation of Bondarenko self-shielded neutron cross sections and multiband parameters from data in the ENDF/B format

Description: Program GROUPIE reads evaluated data in the ENDF/B format and uses these data to calculate Bondarenko self-shielded cross sections and multiband parameters. To give as much generality as possible, the program allows the user to specify arbitrary energy groups and an arbitrary energy groups and an arbitrary energy-dependent neutron spectrum (weighing function). To guarantee the accuracy of the results, all integrals are performed analytically; in no case is iteration or any approximate form of i… more

Stellarmak a hybrid stellarator: Spheromak

Description: This paper discusses hybridization of modified Stellarator-like transform windings (T-windings) with a Spheromak or Field-Reversed-Mirror configuration. This configuration, Stellarmak, retains the important topological advantage of the Spheromak or FRM of having no plasma linking conductors or blankets. The T-windings provide rotational transformation in toroidal angle of the outer poloidal field lines, in effect creating a reversed B/sub Toroidal/ Spheromak or adding average B/sub T/ to the FR… more

Studies of the dissolution of geothermal scale

Description: Samples of geothermal scale formed from Magmamax No. 1 and Woolsey No. 1 wells in the Imperial Valley, Calif., were exposed to concentrated and dilute solutions of common laboratory reagents. The time of exposure and temperature of the reagent were also varied. Several reagents easily dissolved significant amounts of the scale. An in situ test was performed with marginal success.
