Dramatic improvements have been made to the detonation modeling capability recently incorporated into MACH2. These improvements significantly improve the flexibility of the detonation model, allow for accurate depiction of real explosives, and permit highly efficient modeling of long, coaxial generators. In this document, we will first describe these improvements in some detail. We will then discuss the calibration of the detonation model to two explosive materials, PBX9501 and PBXN110. Finally, we will demonstrate the code`s capability for modeling long, coaxial magnetocumulative generators.

Accurately tracking welder qualification and assigning welders to jobs for which they are qualified is becoming more important as customers increasingly demand improved quality and conformance to industry standards. A computerized welder qualification records and tracking system (WPQ) was developed at the Oak Ridge Y-12 Plant to assist the user in this process. The system enables the user to consistently generate welder qualification records with minimal effort and increased accuracy, relate the welder qualification limits with the limits of the welding procedure specification, generate a printout which reports essential information for selecting qualified welders, and provide a method for updating welders based on process usage as permitted by the codes. Codes addressed by the system include American Society of Mechanical Engineers (ASME) Section IX, American Welding Society (AWS) D1.1, AWS D1.3 and AWS D9.1

The present report summarizes recent progress on the Phase I effort during the period January 1, 1994 through March 30, 1994. This report summarizes progress to date in refining the existing analytical models implemented in the IECM. In this report, the authors described the development of analytical models for the performance and costs of high-performance particulate control technologies, focusing on fabric filters. They pay special attention to developing models which can be used to estimate costs for systems whose performance is up to a factor of three below the present NSPS standards of 0.03 lb/MMBtu. Typically, the cost models relate the capital costs and the operating and maintenance (O&M) costs to process parameters and the costs of labor and materials. The capital cost models are anchored to a base capital cost for a specific size unit and adjusted according to the actual or design parameters. The performance models are constructed to estimate the process parameters for a desired level of emission control. The primary motivation for these models is to estimate the costs of complying with environmental standards on a basis which reflects recent advances in control technology. Finally, the authors incorporate the uncertainties in various process parameters and inputs …

Experimental study of low energy, highly charged ions with other atomic species requires an advanced ion source such as an electron beam ion source, EBIS or an electron cyclotron ion source, ECRIS. Five years ago we finished the design and construction of the Cornell superconducting solenoid, cryogenic EBIS (CEBIS). Since then, this source has been in continuous operation in a program whose main purpose is the experimental study of interactions of highly charged ions with atoms at keV energies. This progress report for the period February 16, 1993 to April 15, 1994 describes the work accomplished during this time in the form of short abstracts.

This DOE research project was established to document the integrated team approach for solving reservoir engineering problems. A field study integrating the disciplines of geology, geophysics, and petroleum engineering will be the mechanism for documenting the integrated approach. This is an area of keen interest to the oil and gas industry The goal will be to provide tools and approaches that can be used to detect reservoir compartments, reach a better reserve estimate, and improve profits early in the life of a field. Brief summaries of the project status are presented for: reservoir selection and data gathering; outcrop/corel log analysis/and correlations; internal architecture description; seismic analysis; and permeability experimental work.

This paper reports on the progress of a project to retrofit a Florida coal-fired power plant with a coal gasification combined cycle. Work has progressed on preliminary engineering, procurement, and a draft environmental impact statement. The paper discusses the resizing of the hot gas cleanup system, the modification of the schedule to eliminate the simple cycle commercialization and combine it with the combined cycle commercial operation, and the transport and installation of the radiant syngas cooler which is coming from Germany.

The study documented in WSRC-TR-93-614 performed an evaluation of the criticality potential associated with the Disassembly Basin Sand Filter for K and L Areas. The document reviewed incorporated results of calculations documented in the engineering calculation N-CLC-K-00151. Analyses of the contents of disassembly basin sludge has indicated that the sludge contains fissile material in excess of subcritical mass limits as specified in ANSI/ANS standards. Previous studies had determined that the fissile material can not collect into a critical configuration in the basin. Since the sand filter is intended to remove suspended particles from the basin water and could serve as a mechanism to collect the fissile material into a critical configuration, the study examined conditions under which criticality could occur in the sand filter. The study shows that criticality is not considered possible in the sand filter. This review emphasized the technical accuracy and presentation of the evaluation. The evaluation was also examined for the elements required for NCSEs. The review was performed in accordance with the NRTSC technical review requirements and procedures and the E7 Manual technical review requirements. The technical review (per the E7 manual) of the engineering calculation (N-CLC-K-0 1 5 1) was previously performed by this …

One of the programs of the Magnetic fusion Energy (MFE) Theory and computations Program is studying the anomalous transport of thermal energy across the field lines in the core of a tokamak. We use the method of gyrokinetic particle-in-cell simulation in this study. For this LDRD project we employed massively parallel processing, new algorithms, and new algorithms, and new formal techniques to improve this research. Specifically, we sought to take steps toward: researching experimentally-relevant parameters in our simulations, learning parallel computing to have as a resource for our group, and achieving a 100 {times} speedup over our starting-point Cray2 simulation code`s performance.
