Radiolytic and Thermal Generation of Gases from Hanford Grout Samples : Interim Report

Description: Gamma irradiation of WHC-supplied samples of grouted Tank 102-AP simulated nonradioactive waste has been carried out at three dose rates, 0.25, 0.63, and 130 krad/hr. The low dose rate corresponds to that in the actual grout vaults; with the high dose rate, doses equivalent to more than 40 years in the grout vault were achieved. An average G(H2) = 0.047 molecules/100 eV was found, independent of dose rate. The rate of H2 production decreases above 80 Mrad. For other gases, G(N2) = 0.12, G(O2) =… more

Radiolytic and Radiolytically Induced Generation of Gases from Synthetic Wastes : Final Report

Description: To better understand the processes leading to the generation and release of gases from waste tanks, the authors studied the radiolytic and thermal generation of H2, N2O, N2, O2, and NH3 in nonradioactive waste simulant solutions and slurries. The radiolytic sources for H2 are e(sub aq)⁻ and its predecessors and H atoms. Radiolysis of the water generates some H2 and an additional amount comes from the hydrogen abstraction reaction H + RH(yields) H2+R(center_dot). Nitrate scavenges e(sub aq)(sup … more

Programming in Fortran M Revision 1

Description: Fortran M is a small set of extensions to Fortran that supports a modular approach to the construction of sequential and parallel programs. Fortran M programs use channels to plug together processes which may be written in Fortran M or Fortran 77. Processes communicate by sending and receiving messages on channels. Channels and processes can be created dynamically, but programs remain deterministic unless specialized nondeterministic constructs are used. Fortran M programs can execute on a rang… more

Background to the Overthrow of President Aristide

Description: This report provides background information on the violent and authoritarian traditions that have characterized Haiti's political dynamics since Haiti attained independence in 1804. It examines Haiti's difficult path toward democracy after the fall of the Duvalier regime, from numerous short-lived governments until the election of Aristide. Finally, the report also surveys Aristide's rule and his subsequent overthrow by the Haitian military.

Thermo-hydraulic analysis of the TPX superconducting TF magnets

Description: The superconducting magnets in Fusion Reactors are subjected to pulsed, nuclear, and resistive heating. The thermo-hydraulic response of the helium forced-flow cooled conductors to the various heat sources is critical to magnet design and performance. Recently developed computer codes allow accurate modeling of conductor response and have been used as an aid to design of the toroidal field (TF) magnets for the Tokamak Physics eXperiment (TPX). The authors present results of design studies that … more

Enhanced Coherence X-Ray Laser Experiments and Simulations

Description: Bright, spatially coherent x-ray lasers (XRLs) have applications in areas such as holography, interferometric imaging, and non-linear optics. Nominally, the authors can improve XRL coherence by either increasing the length or by reducing the aperture. Length can be increased by coupling multiple stages of XRLs or by using multilayer optics, but the effective gain length of an XRL is limited by refractive propagation and multilayer damages. The laser aperture is typically limited by the best-foc… more

Fast-neutron scattering from vibrational palladium nuclei

Description: Neutron total cross sections of elemental palladium are measured from {approx}0.6--4.5 MeV. These results, combined with others previously reported from this laboratory, provide a detailed knowledge of the neutron total cross sections of palladium from {approx}0.1--20 MeV. Differential neutron elastic-scattering cross sections are measured from {approx}1.5--10 MeV in sufficient energy and angle detail to well define the energy-average behavior. Concurrently, neutron inelastic-scattering cross s… more

A literature review of actinide-carbonate mineral interactions

Description: Chemical retardation of actinides in groundwater systems is a potentially important mechanism for assessing the performance of the Waste Isolation Pilot Plant (WIPP), a facility intended to demonstrate safe disposal of transuranic waste. Rigorous estimation of chemical retardation during transport through the Culebra Dolomite, a water-bearing unit overlying the WIPP, requires a mechanistic understanding of chemical reactions between dissolved elements and mineral surfaces. This report represent… more

Microwave Michelson Interferometer system report of first use on a railgun, Green Farm, San Diego, CA

Description: This report summarizes the successful first attempt to use a Michelson microwave interferometer to measure the position of a projectile throughout its acceleration by a railgun. The test was performed at the DNA Green Farm facility operated by Maxwell Labs Inc. The test was performed using the ARDEC-ACB gun to accelerate a 1.1 kg polycarbonate projectile-to about 2.5 km/s. The projectile had an initial injection velocity of about 490 m/s.

TORT certification package

Description: The TORT code has been certified. TORT is a three-dimensional discrete ordinates transport theory code, than can solve neutron, photon, or coupled neutron/photon problems. The code will be used primarily for shielding and radiation field calculations SRS. As defined in this work, certification dies not imply validation. The code must be validated for a particular type of calculation before it can be used for critical applications.

Integrated seismic study of naturally fractured tight gas reservoirs. Technical progress report for the period: 7/1/93--9/31/93

Description: The study area is located at the southern end of the Powder River Basin in Converse County in east-central Wyoming. It is a low permeability fractured site, with both gas and oil present. Reservoirs are highly compartmentalized due to the low permeabilities, and fractures provide the only practical paths of production. During this eighth quarter of the seismic study of this area, work continued in processing seismic data, collecting additional geological information to aid in the interpretation… more
