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 Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents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.

This paper describes an application of the U.S. Department of Energy`s (DOE) performance goal based method for the design and evaluation of structures, systems, and components (SSCS) at Fluor Daniel Hanford, Inc. (FDH). The philosophy on which DOE`s method is based has been employed to construct a graded approach to the minimum structural design and evaluation criteriz@ used at the DOE Hanford Site that complies with the DOE Order 54E;0.28, Natural Phenomena Hazards Mitigation. The FDH structural design and evaluation criteria applies to both nuclear and non-nuclear SSCs that are not covered by a reactor safety analysis report.

This semiannual progress report contains the following appendices: description of the 1,000 lb steam/h watertube research boiler; the Pennsylvania CGE model; Phase II, subtask 3.9 coal market analysis; the CGE model; and sector definition.

This program is being conducted as a cooperative agreement between the Consortium for Coal Water Mixture Technology and the U.S. Department of Energy. Activities this reporting period are summarized by phase. Phase I is nearly completed. During this reporting period, coal beneficiation/preparation studies, engineering designs and economics for retrofitting the Crane, Indiana boiler to fire coal-based fuels, and a 1,000-hour demonstration of dry, micronized coal were completed. In addition, a demonstration-scale micronized-coal water mixture (MCWM) preparation circuit was constructed and a 1,000-hour demonstration firing MCWM began. Work in Phase II focused on emissions reductions, coal beneficiation/preparation studies, and economic analyses of coal use. Emissions reductions investigations involved literature surveys of NO{sub x}, SO{sub 2}, trace metals, volatile organic compounds, and fine particulate matter capture. In addition, vendors and engineering firms were contacted to identify the appropriate emissions technologies for the installation of commercial NO{sub x} and SO{sub 2} removal systems on the demonstration boiler. Information from the literature surveys and engineering firms will be used to identify, design, and install a control system(s). Work continued on the refinement and optimization of coal grinding and MCWM preparation procedures, and on the development of advanced processes for beneficiating high ash, high sulfur …

Goal of the National Ignition Facility (NIF) is to achieve thermonuclear ignition in a laboratory environment in inertial confinement fusion (ICF). This will enable NIF to service the DOE stockpile stewardship management program, inertial fusion energy goals, and advance scientific frontiers. All of these applications will make use of the extreme conditions that the facility will create in the target chamber. In the case of a prospected 20 MJ yield scenario, NIF will produce 10{sup 19} neutrons with DT fusion 14 MeV energy per neutron. There will also be high-energy x rays as well as solid, liquid, and gaseous target debris produced either directly or indirectly by the inertial confinement fusion process. A critical design issue is the protection of the final optical components as well as sophisticated target diagnostics in such a harsh environment.

Designing a computer control system for the National Ignition Facility (NIF) is a complex undertaking because of the system`s large size and its distributed nature. The controls team is addressing that complexity by adopting the object-oriented programming paradigm, designing reusable software frameworks, and using the Common Object Request Broker Architecture (CORBA) for distribution. A prototype system for image-based automatic laser alignment has been developed to evaluate and gain experience with CORBA and OOP in a small distributed system. The prototype is also important in evaluating alignment concepts, image processing techniques, speed and accuracy of automatic alignment objectives for the NIF, and control hardware for aligment devices. The prototype system has met its inital objectives and provides a basis for continued development.

The second phase, coating of Si{sub 3}N{sub 4} by oxides, was started during this reporting period. Si{sub 3}N{sub 4} samples were coated by CMZP and Mg-coated Al{sub 2}TiO{sub 5} by a double-dip procedure.

We summarize our calculation of the total cross section for top quark production at hadron colliders within the context of perturbative quantum chromodynamics, including resummation of the effects of initial-state soft gluon radiation to all orders in the strong coupling strength.

This paper discusses the regulatory exemptions for shipping packages that contain limited amounts of fissile material and concerns that have arisen over the adequacy of these regulations. The results of an ongoing review of these exemptions by the various regulatory agencies will be presented in the session.

Periodical discussing the United States Supreme Court's decision that Texas's redistricting in the early 1990s was unconstitutional. It summarizes the court's opinion and addresses the potential impact of redrawing districts in Texas for the 1996 congressional elections.

Due to the relocation of a magnet power supply, the installation of a buss, and an installation of chokes. and their need for cooling water a redesign of the Low Conductivity Water (LCW) system has been undertaken. This new system required the determination of an optimal pipe diameter for the High Bay pipe as well as the determination of the pressure drop and temperature rise in the buss. Based on numerous calculations it has been determined that the High Bay pipe should be 1 1/2 inch (1.90 O.D. x 1.610 I.D-40S steel). While the pressure drop in the buss was calculated to be 7.699 psi. Based on such a low pressure drop, no need for any additional pumps has presented itself. Finally, the temperature rise in the buss has been determined to be about 29.39 F for the Assembly Hall (route No.1). and 13.93 F for the Collision Hall (route No.2). The purpose of this engineering note is to explain the redesign of the low conductivity water system (LCW) at D-Zero. The areas to be covered include the sizing of the High Bay, the pressure drop and temperature rise in the buss. In addition, I will try to determine if …
