A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

One key aspect for high gain direct drive inertial confinement fusion is the imprint of perturbations in the outer surface of a capsule due to nonuniformities in the direct laser illumination of the capsule. Direct drive implosions are achieved by uniformly irradiating the outside surface of a hollow spherical capsule that contains a layer of fusionable D-T on its inner surface. The intensity of laser irradiation is down with a low intensity ``foot`` at 10{sup 13} W/cm{sup 2} for several nanoseconds before it builds up to more than 10{sup 15} W/cm{sup 2} during the main drive portion of the pulse. Laser ablation of the capsule surface produces a high pressure that accelerates the capsule shell radially inward in a spherical implosion. During this acceleration, perturbations due to surface roughness and due to imprint from spatial nonuniformities in the laser irradiation undergo Rayleigh-Taylor growth, potentially severely degrading performance. Our interest is in studying the imprint process and subsequent Rayleigh-Taylor growth of perturbations in a foil target that is irradiated by a low intensity laser speckle pattern. Previous experiments have been done to study laser imprint with an x-ray laser backlighter at the Nova laser using 0.35 micrometer laser irradiation of a …

The objective of this project was to characterize metallic emissions from representative coals and develop strategies for their control. A technique for flue gas desulfurization is the use of calcium based sorbents, and the degree of metals capture of these sorbents under different conditions will be researched. The objective of the first year of the study was to understand the evolution of metallic aerosol size distributions and the capture characteristics of various sorbents. Also, the metallic emissions resulting from the combustion of two seams of Ohio coals were to be characterized. Studies on the evolution of the metallic aerosol size distributions have been completed and the use of silicon and calcium based sorbents for capture of lead species has been examined. Co-injection of metallic compounds along with organometallic silicon indicated a high degree of capture of lead in a certain temperature region. Preliminary results with calcium based sorbents also indicate capture of metallic species. In the second year, the work was extended to examine three different aspects: (1) understanding the mechanisms of capture of metals by vapor phase sorbents; (2) role of chlorine in speciation of metals and its importance in metals capture; and (3) capture of mercury by aerosol …

Vegetation at Yucca Mountain, Nevada, was monitored over a six-year period, from 1989 through 1994. Yucca Mountain is located at the northern limit of the Mojave Desert and is the only location being studied as a potential repository for high-level nuclear waste. Site characterization consists of a series of multidisciplinary, scientific investigations designed to provide detailed information necessary to assess the suitability of the Yucca Mountain Site as a repository. This vegetation description establishes a baseline for determining the ecological impact of site characterization activities; it porvides input for site characterization research and modeling; and it clarifies vegetation community dynamics and relationships to the physical environment. A companion study will describe the impact of site characterization of vegetation. Cover, density, production, and species composition of vascular plants were monitored at 48 Ecological Study Plots (ESPs) stratified in four vegetation associations. Precipitation, soil moisture, and maximum and minimum temperatures also were measured at each study plot.

This document covers the End Point Criteria for Fuel Supply Shutdown Facilities that is to be attained for the transfer of these facilities to the EM-40 Program.

This document summarizes the information on the historical uses, present status, and the sampling and analysis results of waste stored in Tank 241-SY-103. This report supports the requirements of the Tri-Party Agreement Milestone M-44-09.

The objective of these studies which began in 1993 was to provide new information on electron and ion transport and reactions in model liquids and biomimetic systems that is pertinent to the roles of charged species in inducing radiobiological damage and to elucidate the interrelationship among the carcinogenicity, mutagenicity and electrophilicity of chemicals. This final report summarizes research efforts in the following areas: electrons in biological systems; and electron and ion transport and reactions in model liquids. In biological systems attention was focused on the following: excess electrons as probes of carcinogen electrophilicity; cost effectiveness of k{sub e} as a carcinogen-screening test; and conversion of k{sub e} to a carcinogen-screening electronic device. In model liquids, research was focused on two areas. The first investigated radiation-induced dimerization of fullerenes. The second area studied radiolytic synthesis of fullerene derivatives.

There are a wide variety of radioactive, toxic, and heavy metal contaminants in the ground waters and soils at DOE facilities. Some of the most common are uranium, technetium, trichloroethylene, and polychlorinated biphenyls. The project is a challenging task based on several key factors. For the removal of radio nuclide or heavy metal particles, first, on a mass fraction basis there is only a small amount of radionuclide particles in either writer or soil. In this way, a successful separation process must be capable of removing small amount of radio nuclide particles or other heavy metals from a very large quantities of soil or water. This feature poses a significant difficulty for most separation technologies which have a low specific processing capacity. Second, in addition to the need to have a high specific processing capacity, the separation technology must be able to selectively separate fine particles. For example, it is expected that most of radionuclide particles as well as 10-30% of the soil particles (depending on the site) are in the size range of less than 100 microns. Thus, a successful separation process must also be capable of efficiently removing minute quantities of small-sized particles from large quantities of soil …

This analysis is prepared by the Mined Geologic Disposal System (MGDS) Waste Package Development Department (WPDD) to determine the viability of the Defense High-Level Waste (DHLW) Glass waste package concept with respect to criticality regulatory requirements in compliance with the goals of the Waste Package Implementation Plan (Ref. 5.1) for conceptual design. These design calculations are performed in sufficient detail to provide a comprehensive comparison base with other design alternatives. The objective of this evaluation is to show to what extent the concept meets the regulatory requirements or indicate additional measures that are required for the intact waste package.
