Characterization of oil and gas waste disposal practices and assessment of treatment costs. Final report

Description: This study examines wastes associated with the onshore exploration and production of crude oil and natural gas in the US. The objective of this study was to update and enhance the current state of knowledge with regard to oil and gas waste quantities, the potential environmental impact of these wastes, potential methods of treatment, and the costs associated with meeting various degrees of treatment. To meet this objective, the study consisted of three tasks: (1) the development of a production… more

Characterization of stainless steel 304 tubing

Description: Earlier studies have shown that stainless steel 304 (SS304) containing martensite is susceptible to hydrogen embrittlement. This generated concern regarding the structural integrity of SS304 tubing we use in the W87 pit tube. During surveillance operations, the pit tube undergoes a series of bending and straightening as it goes through a number of surveillance cycles. This motivated the study to characterize austenitic SS304 tubing obtained from Rocky Flats. The tubes continued to display struc… more

Chinese Missile and Nuclear Proliferation: Issues for Congress

Description: The President has identified proliferation as a primary danger to U.S. security interests. China has contributed to the danger by providing nuclear weapons technology to Pakistan, and other nuclear technology to Iran and Algeria. China has also supplied CSS-2 intermediate range ballistic missiles to Saudi Arabia, Silkworm anti-ship missiles to Iran and Iraq, and ballistic missile technology to Pakistan and perhaps Iran, North Korea and others. China developed the mobile, solid-fuel M-9 and M-… more

Configuration management compliance matrix for K Basins

Description: This compliance matrix identifies the criteria of the configuration management program at K Basins and identifies the current methods, i.e., systems, processes, procedures, and programs, that implement the configuration management criteria. The matrix identifies the current K Basins implementing methods established through an initial assessment. This initial assessment of the implementation is reflected in the compliance matrix and forms the basis for subsequent detailed evaluations to ensure t… more

D0 Silicon Upgrade: Transfer Line Branch Considerations for Solenoid & VLPC

Description: The transfer line for the solenoid currently has a dead branch on it. Issues regarding the solenoid transfer line also apply to the VLPC transfer line. Issues that need to be addressed are: (1) What is the heat load on the branch? (2) Would it be a good idea to run the LN2 radiation shield on the branch? (3) What are the thermal acoustic oscillation parameters of a dead headed branch? A simple remedy, although not analyzed was to install a jumper with a flow restriction at the end of the helium… more

DSI3D-RCS: Theory manual

Description: The DSI3D-RCS code is designed to numerically evaluate radar cross sections on complex objects by solving Maxwell`s curl equations in the time-domain and in three space dimensions. The code has been designed to run on the new parallel processing computers as well as on conventional serial computers. The DSI3D-RCS code is unique for the following reasons: Allows the use of unstructured non-orthogonal grids, allows a variety of cell or element types, reduces to be the Finite Difference Time Domai… more

Energy and particle flow in low temperature plasmas

Description: Increased interest in the development of high density plasma sources for ultra large scale integrated circuit manufacturing with varying geometry and power coupling strategies require the development of 2D models for accurate plasma reactor studies. An objective of their research was to develop a computationally efficient numerical code that would be useful as a design tool for inductively coupled plasma reactors. To achieve that goal the authors created a 2D fluid model (INDUCT2D) of an argon … more

Enhancing the use of coals by gas reburning-sorbent injection. Quarterly report No. 30, January 1--March 31, 1995

Description: The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x} and sulfur (SO{sub x}), on two coal fired utility boilers in Illinois. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 50 percent in SO{sub x} emissions, by a combination of two developed technologies, gas reburning (GR) and sorbent injection (SI). With GR, about 80--85 percent of the coal fuel is f… more

Enhancing the use of coals by gas reburning-sorbent injection. Quarterly report No. 32, July 1--September 30, 1995

Description: The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitions. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 5… more

Ergodic mixing for turbulent drift motion

Description: The statistical properties of the long-time chaotic two-dimensional (2D) drift motion of a charged particle in an inhomogeneous magnetic field {beta}(x,y) and a time-dependent electrostatic potential {phi}(x,y,t) are studied by numerical symplectic integration. For a conditionally periodic potential with two or more incommensurate frequencies, an ergodic behavior is demonstrated in which the probability density of the particle position is proportional to the magnetic field {beta}. The accuracy … more

Evaluation of gas-reburning and low NO{sub x} burners on a wall fired boiler. Progress report No. 18, January 1--March 31, 1995

Description: The primary objective of this project is to evaluate the use of Gas Reburning and Low NO{sub x} Burners (GR-LNB) for NO{sub x} emission control from a wall fired boiler. It is anticipated that, if the demonstration is successful, the GR-LNB technology could become commercialized during the 1990`s and will be capable of (1) achieving significant reduction in the emissions of nitrogen oxides and sulfur dioxide (another acid rain precursor) from existing facilities to minimize environmental impact… more

Extending Fuzzy System Concepts for Control of a Vitrification Melter

Description: Fuzzy systems provide a mathematical framework to capture uncertainty. The complete description of real, complex systems or situations often requires far more detail and information than could ever be obtained (or understood). Fuzzy approaches are an alternative technology for both system control and information processing and management. In this paper, we present the design of a fuzzy control system for a melter used in the vitrification of hazardous waste. Design issues, especially those rela… more

Finding the Higgs boson: A status report

Description: The search for the Higgs boson of the minimal Standard Model has been a major focus of experimental high energy physics for some years now. Here, the authors review the current experimental limits and discuss the prospects for finding the Higgs boson at future accelerators, such as LEPII and the LHC. They consider only the Standard Model Higgs boson. Since a null result which definitively excluded a Higgs boson below some mass scale would be extremely important, they emphasize the case where th… more

Functional design criteria 241-AP-102 Flexible Receiver System

Description: A mixer pump was installed in the 1.07 m (42-in.) riser of the central pump pit of tank 241-AP-102 to mitigate potential fluid separation particle sedimentation by mixing the tank`s contents. The mixer pump performed this function until failure. Its removal is now necessary to meet possible tank content removal commitments or other corrective actions. The proposed removal procedure requires a flexible receiver that will provide a barrier to contamination during removal and transfer of the pump … more
