Probing processes are used intermittently and not effectively as an on-line measurement device. This project was needed to evolve machine probing from merely a setup aid to an on-the-machine inspection system. Use of probing for on-machine inspection would significantly decrease cycle time by elimination of the need for first-piece inspection (at a remote location). Federal Manufacturing and Technologies (FM and T) had the manufacturing facility and the ability to integrate the system into production. The Contractor had a system that could optimize the machine tool to compensate for thermal growth and related error.

The objective of this project is to design, construct and field demonstrate a membrane system to recover natural gas liquids (NGL) and remove water from raw natural gas. An extended field test to demonstrate system performance under real-world conditions would convince industry users of the efficiency and reliability of the process. The system has been designed and fabricated by Membrane Technology and Research, Inc. (MTR) and will be installed and operated at British Petroleum (BP)-Amoco's Pascagoula, MS plant. The Gas Research Institute will partially support the field demonstration and BP-Amoco will help install the unit and provide onsite operators and utilities. The gas processed by the membrane system will meet pipeline specifications for dewpoint and Btu value and can be delivered without further treatment to the pipeline. Based on data from prior membrane module tests, the process is likely to be significantly less expensive than glycol dehydration followed by propane refrigeration, the principal competitive technology. At the end of this demonstration project the process will be ready for commercialization. The route to commercialization will be developed during this project and may involve collaboration with other companies already servicing the natural gas processing industry.

Iron aluminide weld overlays are being investigated for corrosion and erosion protection of boiler tubes in low NOx burners. The primary objective of the research is to identify overlay compositions which can be deposited in a crack-free condition and provide corrosion protection in moderately reducing environments. In the current phase of work, Fe-Al alloy weld overlays were produced by depositing commercially pure aluminum wire on to low carbon steel substrates using Gas Tungsten Arc Welding. A systematic variation of the wire feed speed and current, two major factors affecting dilution, resulted in a variation in aluminum contents of the welds ranging from 3--42 wt% aluminum. The aluminum content was observed to increase with wire feed speed and a decrease in the current. The aluminum content was also found to affect the cracking susceptibility of the overlays. At 10wt% aluminum, few to no cracks were observed in the deposits. Above this value, cracking was prevalent throughout the weld. In addition, two types of microstructures were found correlating to different concentrations of aluminum. A homogeneous matrix with second phase particles consisting of coarse columnar grains was found for low aluminum concentrations. With higher aluminum contents, a two-phase constituent was observed to surround …

SRNL was tasked to simulate the draining of interstitial liquid from Tank 25 saltcake which is scheduled to take place in 2005. The salt processing plan baseline identifies a target of 135,000 gallons of interstitial liquid to be removed from Tank 25. Due to the uncertainty of the Tank 25 material properties and conditions, several cases were modeled varying the saltcake and interstitial liquid properties. The cases present a wide range of performance. The nominal baseline, case 1, removed the 135,000 gallons in approximately 1,030 hours of pump operation. The cases with optimal drain characteristics (high intrinsic permeability, high temp.) drain the 135,000 gallons in less time. Those with less favorable drain conditions did not approach the 135,000 gallons in a reasonable amount of time. Common to all cases unable to achieve the target volume was the low temperature at which they were run, 30 C (the lowest modeled), though there were additional contributing factors. A summary of the results are shown in Table 1.

Plutonium solutions stored at the Plutonium Finishing Plant must be treated to convert the plutonium to a safe, solid form for storage and to remove the americium so that radiation exposure can be reduced. Extraction chromatographic resins will be tested for separating plutonium from these solutions in the laboratory. Separation parameters will be developed during the testing for large scale processing of the solutions. Use of chromatographic resins will allow plutonium separation with minimum of chemical addition to the feed and without the need for plutonium valence adjustment. The separated plutonium will be calcined to plutonium oxide by direct solution calcination.

This document examines the potential use of Thomson-Radiated Extreme X-ray (T-REX) sources for Fluorescence Imaging in the Nuclear Domain (FIND) of special nuclear materials. A back-of-the-envelope, relative comparison of T-REX sources vs. Bremsstrahlung sources for this application is presented. It is estimated that use of T-REX for FIND could be as much as 5 x 10{sup 12} more effective than the use of anode based sources. Furthermore it is estimated that illumination of samples of dimension 1 cm on a side could produce up to {approx}10{sup 9} detectable photons per second.

The objective of this proposed research is to improve and expand the detection and analysis capabilities of the automated, concrete evaluation (ACE) system. MoDOT and Honeywell jointly developed this system. The focus of this proposed research will be on the following: Coordination of concrete imaging efforts with other states, Validation and testing of the ACE system on a broad range of concrete samples, and Identification and development of software and hardware enhancements. These enhancements will meet the needs of diverse users in the field of concrete materials, construction, and research.

This report details the progress made in by the SuperB Project in the area of the Collider since the publication of the SuperB Conceptual Design Report in 2007 and the Proceedings of SuperB Workshop VI in Valencia in 2008. With this document we propose a new electron positron colliding beam accelerator to be built in Italy to study flavor physics in the B-meson system at an energy of 10 GeV in the center-of-mass. This facility is called a high luminosity B-factory with a project name 'SuperB'. This project builds on a long history of successful e+e- colliders built around the world, as illustrated in Figure 1.1. The key advances in the design of this accelerator come from recent successes at the DAFNE collider at INFN in Frascati, Italy, at PEP-II at SLAC in California, USA, and at KEKB at KEK in Tsukuba Japan, and from new concepts in beam manipulation at the interaction region (IP) called 'crab waist'. This new collider comprises of two colliding beam rings, one at 4.2 GeV and one at 6.7 GeV, a common interaction region, a new injection system at full beam energies, and one of the two beams longitudinally polarized at the IP. Most …

A new temperature-profile method was recently developed for analyzing perturbed flow conditions in superheated porous media. The method uses high-resolution temperature data to estimate the magnitude of the heat-driven liquid and gas fluxes that form as a result of boiling, condensation, and recirculation of pore water. In this paper, we evaluate the applicability of this new method to the more complex flow behavior in fractured formations with porous rock matrix. In such formations, with their intrinsic heterogeneity, the porous but low-permeable matrix provides most of the mass and heat storage capacity, and dominates conductive heat transfer, Fractures, on the other hand, offer highly effective conduits for gas and liquid flow, thereby generating significant convective heat transfer. After establishing the accuracy of the temperature-profile method for fractured porous formations, we apply the method in analyzing the perturbed flow conditions in a large-scale underground heater test conducted in unsaturated fractured porous tuff. The flux estimates for this test indicate a significant reflux of water near the heat source, on the order of a few hundred millimeter per year-much larger than the ambient percolation flux of only a few millimeter per year.

Environmental Surveillance of the Hanford Site and surrounding areas is conducted by the Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy (DOE).

This calculation documents the design of the Spent Nuclear Fuel (SNF) and High-Level Waste (HLW) Cask storage slab for the Aging Area. The design is based on the weights of casks that may be stored on the slab, the weights of vehicles that may be used to move the casks, and the layout shown on the sketch for a 1000 Metric Ton of Heavy Metal (MTHM) storage pad on Attachment 2, Sht.1 of the calculation 170-C0C-C000-00100-000-00A (BSC 2004a). The analytical model used herein is based on the storage area for 8 vertical casks. To simplify the model, the storage area of the horizontal concrete modules and their related shield walls is not included. The heavy weights of the vertical storage casks and the tensile forces due to pullout at the anchorages will produce design moments and shear forces that will envelope those that would occur in the storage area of the horizontal modules. The design loadings will also include snow and live loads. In addition, the design will also reflect pertinent geotechnical data. This calculation will document the preliminary thickness and general reinforcing steel requirements for the slab. This calculation also documents the initial design of the cask anchorage. Other …

Two stirred tank slurry reactor tests of catalysts with nominal compositions 100 Fe/3Cu/4 K/2 Ca/16 SiO{sub 2} (run SB-3115) and 100 Fe/5 Cu/6 K/24 SiO{sub 2} (run SA-3155) were completed under task 5, The Effect of Source of Potassium and Basic Oxide Promoter, during the reporting period. Our assessment of the effects of addition of CaO promoter to our baseline catalysts B and C and the use of potassium silicate as the source of potassium promoter is as follows: in general, the addition of CaO promoter did not result in improved performance of the baseline catalysts; the use of CaO promoter may be best suited for operation at higher reaction pressures; the baseline procedure utilizing impregnation of Fe-Cu-SiO{sub 2} precursor with aqueous solution of KHCO{sub 3} as the source of potassium promoter is the preferred method of preparation; and the procedure which utilizes aqueous K{sub 2}SiO{sub 3} solution as the source of potassium also provides satisfactory results, and may be used as an alternative. A slurry reactor test (run SB-3425) was completed during the reporting period, following the catalyst pretreatment with H{sub 2} at 250{degrees}C for 4 h (Task 6. Pretreatment Effect Research). This pretreatment resulted in higher catalyst activity …

ORNL's advanced characterization capabilities were used to determine the physical and chemical structure of magnetic multilayer films intended for application in non-volatile magnetic random access memory devices and as magnetic sensors. ORNL modeling capabilities were used to incorporate this information into a first-principles based tool that can be used to model the magnetic and transport properties of these films. This modeling capability should be useful for understanding and optimizing novel magnetoelectronic devices.

This report summarizes the 1991 calendar year activities of the fusion gamma ray diagnostics project in the Physics Department at the Colorado School of Mines. Considerable progress has been realized in the fusion gamma ray diagnostic project in the last year. Specifically we have achieved the two major goals of the project as outlined in last year`s proposed work statement to the Office of Applied Plasma Physics in the DOE Division of Magnetic Fusion Energy. The two major goals were: (1) Solution of the severe interference problem encountered during the operation of the gamma ray spectrometer concurrent with high power levels of the neutral beam injectors (NBI) and the ICRH antenae. (2) Experimental determination of the absolute detection efficiency of the gamma ray spectrometer. This detection efficiency will allow the measured yields of the gamma rays to be converted to a total reaction rate. In addition to these two major accomplishments, we have continued, as permitted by the TFTR operating schedule, the observation of high energy gamma rays from the 3He(D,{gamma})5Li reaction during deuterium NBI heating of 3He plasmas.
