The Ability of the United States Federal Radiological Monitoring and Assessment Center to Collect and Disseminate Environmental Measurements during Radiological Emergencies (open access)

The Ability of the United States Federal Radiological Monitoring and Assessment Center to Collect and Disseminate Environmental Measurements during Radiological Emergencies

The Federal Radiological Monitoring and Assessment Center (FRMAC) is the United States’ response organization for radiological emergencies. The FRMAC is structured as an operations center and employs the combined resources of several federal agencies to respond to any disaster resulting in the release of radioactivity. The mission of the FRMAC is to support state and local authorities in the gathering of environmental data using an array of survey equipment ranging from alpha probes, beta/gamma probes, and high-purity germanium (HPGe) spectroscopy to the gathering of physical samples. Once collected, the data are projected on maps to assist public officials make protective action decisions. In addition to the accumulation of data, it is the legal obligation of the FRMAC to keep archival records of all data points and their actions. During an event, it is conceivable that hundreds to thousands of sample points will be recorded over a relatively short time. It is in the interest of the federal government and public that the information collected be put to the best use as fast as possible. Toward this end, the Remote Sensing Laboratory, working under the direction of the United States Department of Energy’s National Nuclear Security Administration, is investigating the use …

ACCU Core Sampling/Storage Device for VOC Analysis (open access)

ACCU Core Sampling/Storage Device for VOC Analysis

The Accu Core sampler system consists of alternating cylindrical clear acrylic sections and one-inch cylindrical stainless steel sections arranged in clear shrink wrap. The set of alternating acrylic and stainless steel sections in the shrink wrap are designed to fit in a Geoprobe dual-tube penetrometer for collection of continuous soil cores. The clear acrylic sections can have 1/2-inch access holes for easy soil headspace screening without violating the integrity of the adjacent stainless steel sections. The Accu Core sampler system can be used to store a soil sample collected in the stainless steel section by capping the ends of the section so it becomes a sample storage container. The sampler system can also be used to collect a subsurface soil sample in one of the sections that can be directly extruded from the section into a container for storage during shipment to the laboratory. In addition, the soil in a sampler section can be quickly sub-sampled using a coring tool and extruded into a storage container so the integrity of the soil is not disrupted and the potential for VOC loss during sub-sampling is greatly reduced. A field validation study was conducted to evaluate the performance of the Accu Core …

Baghouse Slipstream Testing at TXU's Big Brown Station (open access)

Baghouse Slipstream Testing at TXU's Big Brown Station

Performing sorbent testing for mercury control at a large scale is a very expensive endeavor and requires months of planning and careful execution. Even with good planning, there are plant limitations on what operating/design parameters can be varied/tested and when. For parameters that cannot be feasibly tested at the full scale (lower/higher gas flow, different bag material, cleaning methods, sorbents, etc.), an alternative approach is used to perform tests on a slipstream unit using flue gas from the plant. The advantage that a slipstream unit provides is the flexibility to test multiple operating and design parameters and other possible technology options without risking major disruption to the operation of the power plant. Additionally, the results generated are expected to simulate full-scale conditions closely, since the flue gas used during the tests comes directly from the plant in question. The Energy & Environmental Research Center developed and constructed a mobile baghouse that allows for cost-effective testing of impacts related to variation in operating and design parameters, as well as other possible mercury control options. Multiple sorbents, air-to-cloth ratios, bag materials, and cleaning frequencies were evaluated while flue gas was extracted from Big Brown when it fired a 70% Texas lignite-30% Powder …

Borehole seismic monitoring of seismic stimulation at OccidentalPermian Ltd's -- South Wason Clear Fork Unit (open access)

Borehole seismic monitoring of seismic stimulation at OccidentalPermian Ltd's -- South Wason Clear Fork Unit

Seismic stimulation is a proposed enhanced oil recovery(EOR) technique which uses seismic energy to increase oil production. Aspart of an integrated research effort (theory, lab and field studies),LBNL has been measuring the seismic amplitude of various stimulationsources in various oil fields (Majer, et al., 2006, Roberts,et al.,2001, Daley et al., 1999). The amplitude of the seismic waves generatedby a stimulation source is an important parameter for increased oilmobility in both theoretical models and laboratory core studies. Theseismic amplitude, typically in units of seismic strain, can be measuredin-situ by use of a borehole seismometer (geophone). Measuring thedistribution of amplitudes within a reservoir could allow improved designof stimulation source deployment. In March, 2007, we provided in-fieldmonitoring of two stimulation sources operating in Occidental (Oxy)Permian Ltd's South Wasson Clear Fork (SWCU) unit, located near DenverCity, Tx. The stimulation source is a downhole fluid pulsation devicedeveloped by Applied Seismic Research Corp. (ASR). Our monitoring used aborehole wall-locking 3-component geophone operating in two nearbywells.

Changes in vigorous physical activity and incident diabetes inmale runners (open access)

Changes in vigorous physical activity and incident diabetes inmale runners

We examined the dose-response relationship between changes in reported vigorous exercise (running distance, {Delta}km/wk) and self-reported physician diagnosed diabetes in 25,988 men followed prospectively for (mean {+-} SD) 7.8 {+-} 1.8 years. Logistic regression analyses showed that the log odds for diabetes declined significantly in relation to men's {Delta}km/wk (coefficient {+-} SE: -0.012 {+-} 0.004, P < 0.01), which remained significant when adjusted for BMI (-0.018 {+-} 0.003, P < 0.0001). The decline in the log odds for diabetes was related to the distance run at the end of follow-up when adjusted for baseline distance, with (-0.024 {+-} 0.005, P < 0.0001) or without (-0.027 {+-} 0.005, P < 0.0001) adjustment for BMI. Baseline distance was unrelated to diabetes incidence when adjusted for the distance at the end of follow-up. Compared to men who ran <8 km/wk at the end of follow-up, incidence rates in those who ran {ge} 8 km/wk were 95% lower between 35-44 yrs old (P < 0.0001), 92% lower between 45-54 yrs old (P < 0.0001), 87% lower between 55 and 64 years old (P < 0.0001), and 46% lower between 65-75 yrs old (P = 0.30).

Defense Acquisitions: Missile Defense Agency's Flexibility Reduces Transparency of Program Cost

Testimony issued by the Government Accountability Office with an abstract that begins "Over the next 5 years the Missile Defense Agency (MDA) expects to invest $49 billion in the Ballistic Missile Defense (BMD) system's development and fielding. MDA's strategy is to field new capabilities in 2-year blocks. In January 2006, MDA initiated its second block--Block 2006--to protect against attacks from North Korea and the Middle East. Congress requires GAO to assess MDA's progress annually. GAO's March 2007 report addressed MDA's progress during fiscal year 2006 and followed up on program oversight issues and the current status of MDA's quality assurance program. GAO assessed the progress of each element being developed by MDA, examined acquisition laws applicable to major acquisition programs, and reviewed the impact of implemented quality initiatives."

Defense Management: High-Level Leadership Commitment and Actions Are Needed to Address Corrosion Issues

A letter report issued by the Government Accountability Office with an abstract that begins "Corrosion can have a deleterious effect on military equipment and infrastructure in terms of cost, readiness, and safety. Recognizing this concern, the Bob Stump National Defense Authorization Act of Fiscal Year 2003 required the Department of Defense (DOD) to designate an official or organization to oversee and coordinate efforts to prevent and mitigate corrosion. Recently, the National Defense Authorization Act of Fiscal Year 2006 directed GAO to examine the effectiveness of DOD's corrosion prevention and mitigation programs. In addition, GAO evaluated the extent to which DOD has incorporated corrosion prevention planning in acquiring weapon systems. GAO reviewed strategy documents, reviewed corrosion prevention planning for 51 recent major weapon system acquisitions, and interviewed DOD and military service officials."

DERIVATIONS FOR HOOP STRESSES DUE TO SHOCK WAVES IN A TUBE (open access)

DERIVATIONS FOR HOOP STRESSES DUE TO SHOCK WAVES IN A TUBE

Equations describing the hoop stresses in a pipe due to water hammer have been presented in the literature in a series of papers, and this paper discusses the complete derivation of the pertinent equation. The derivation considers the pipe wall response to a water hammer induced shock wave moving along the inner wall of the pipe. Factors such as fluid properties, pipe wall materials, pipe dimensions, and damping are considered. These factors are combined to present a single, albeit rather complicated, equation to describe the pipe wall vibrations and hoop stresses as a function of time. This equation is also compared to another theoretical prediction for hoop stresses, which is also derived herein. Specifically, the two theories predict different maximum stresses, and the differences between these predictions are graphically displayed.

Developing the Galactic Diffuse Emission Model for the GLAST Large Area Telescope (open access)

Developing the Galactic Diffuse Emission Model for the GLAST Large Area Telescope

Diffuse emission is produced in energetic cosmic ray (CR) interactions, mainly protons and electrons, with the interstellar gas and radiation field and contains the information about particle spectra in distant regions of the Galaxy. It may also contain information about exotic processes such as dark matter annihilation, black hole evaporation etc. A model of the diffuse emission is important for determination of the source positions and spectra. Calculation of the Galactic diffuse continuum g-ray emission requires a model for CR propagation as the first step. Such a model is based on theory of particle transport in the interstellar medium as well as on many kinds of data provided by different experiments in Astrophysics and Particle and Nuclear Physics. Such data include: secondary particle and isotopic production cross sections, total interaction nuclear cross sections and lifetimes of radioactive species, gas mass calibrations and gas distribution in the Galaxy (H{sub 2}, H I, H II), interstellar radiation field, CR source distribution and particle spectra at the sources, magnetic field, energy losses, g-ray and synchrotron production mechanisms, and many other issues. We are continuously improving the GALPROP model and the code to keep up with a flow of new data. Improvement in any …

DOD and VA Outpatient Pharmacy Data: Computable Data Are Exchanged for Some Shared Patients, but Additional Steps Could Facilitate Exchanging These Data for All Shared Patients (open access)

DOD and VA Outpatient Pharmacy Data: Computable Data Are Exchanged for Some Shared Patients, but Additional Steps Could Facilitate Exchanging These Data for All Shared Patients

Correspondence issued by the Government Accountability Office with an abstract that begins "Since 1998, the Department of Defense (DOD) and the Department of Veterans Affairs (VA) have been working to electronically exchange patient health data, including outpatient pharmacy data, cross their electronic health information systems. Exchanging outpatient pharmacy data is important for DOD and VA because certain DOD and VA patients, known as shared patients, receive health care from both agencies. Clinicians' access to complete health information from both agencies' health information systems could assist clinicians in making more informed medical decisions and help prevent adverse medication reactions--which include detrimental or unintended reactions when multiple medications are taken together and allergic reactions to a medication. In March 2004, DOD and VA began collaborating on a long-term initiative to make their outpatient pharmacy data computable. Computable data refer to data that are in a format that a computer application can act on: for example, to provide automatic checks for adverse medication reactions or to plot graphs of changes in vital signs such as blood pressure. In reporting on this initiative in the past, GAO noted that the agencies have experienced delays in their efforts to begin exchanging computable outpatient pharmacy data. …

Environmental Biosciences Program Report for Year 3

In May 2002, the United States Department of Energy (DOE) signed Assistance Instrument Number DE-FC09-02CH11109 with the Medical University of South Carolina (MUSC) to support the Environmental Biosciences Program (EBP). This funding instrument replaces DOE Assistance Instrument Number DE-FC02-98CH10902. EBP is an integrated, multidisciplinary scientific research program, employing a range of research initiatives to identify, study and resolve environmental health risks. These initiatives are consistent with the MUSC role as a comprehensive state-supported health sciences institution and with the nation's need for new and better approaches to the solution of a complex and expansive array of environment-related health problems. The intrinsic capabilities of a comprehensive health sciences institution enable MUSC to be a national resource for the scientific investigation of environmental health issues. EBPs success as a nationally prominent research program is due, in part, to its ability to task-organize scientific expertise from multiple disciplines in addressing these complex problems. Current research projects have focused EBP talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene and low-dose ionizing radiation. Work on the trichloroethylene research projects has been slowed as a result of funding …

EXCITATION OF STRUCTURAL RESONANCE DUE TO A BEARING FAILURE (open access)

EXCITATION OF STRUCTURAL RESONANCE DUE TO A BEARING FAILURE

Vibration due to a bearing failure in a pump created significant vibrations in a fifteen foot by fifteen foot by eight feet tall mounting platform due to excitation of resonant frequencies. In this particular application, an 18,000 pound pump was mounted to a structural steel platform. When bearing damage commenced, the platform vibrated with sufficient magnitude that conversations could not be heard within forty feet of the pump. Vibration analysis determined that the frequency of the bearing was coincident to one of the natural frequencies of the pump, which was, in turn, coincident to one of the natural frequencies of the mounting platform. This coincidence of frequencies defines resonance. Resonance creates excessive vibrations when the natural frequency of a structure is coincident to an excitation frequency. In this well documented case, the excitation frequency was related to ball bearing failures. The pump is a forty foot long vertical pump used to mix nuclear waste in 1,300,000 gallon tanks. A 300 horsepower drive motor is mounted to a structural steel platform on top of the tank. The pump hangs down into the tank from above to mix the waste and is inaccessible after installation. Initial awareness of the problem was due …

Exercises Abroad: How Differing National Experiences are Reflected in Emergency Response Planning and Exercises

Recently a member of the U.S. Department of Energy’s (DOE) Consequence Management Response Team took part in outreaches and an exercise in different foreign countries. In Brazil and South Korea, the outreaches revolved around a nuclear power plant exercise. In Canada, participation was limited to a table top Consequence Management exercise. This talk will briefly discuss each event and resulting pertinent observations. In each case, it became evident that governments respond to disasters very differently, and that these differences are not only culturally based, but also influenced by each government’s respective experience in dealing with natural disasters.

Fabrication of (Mn,Co)3O4 Surface Coatings onto Alloy Substrates (open access)

Fabrication of (Mn,Co)3O4 Surface Coatings onto Alloy Substrates

Ferritic stainless steels are promising candidates for IT-SOFC interconnect applications due to their low cost and resistance to oxidation at SOFC operating temperatures. However, several challenges remain, including long term electrical conductivity and surface stability under interconnect exposure conditions and chromia scale evaporation. One means of extending interconnect lifetime and improving performance is to apply a protective coating, such as (Mn,Co)3O4 spinel, to the cathode side of the interconnect. These coatings have proven effective in reducing scale growth kinetics and Cr volatility. This report describes several procedures developed at PNNL for fabricating (Mn,Co)3O4 spinel coatings onto ferritic stainless steels.
