10 MW Supercritical CO2 Turbine Test (open access)

10 MW Supercritical CO2 Turbine Test

The Supercritical CO2 Turbine Test project was to demonstrate the inherent efficiencies of a supercritical carbon dioxide (s-CO2) power turbine and associated turbomachinery under conditions and at a scale relevant to commercial concentrating solar power (CSP) projects, thereby accelerating the commercial deployment of this new power generation technology. The project involved eight partnering organizations: NREL, Sandia National Laboratories, Echogen Power Systems, Abengoa Solar, University of Wisconsin at Madison, Electric Power Research Institute, Barber-Nichols, and the CSP Program of the U.S. Department of Energy. The multi-year project planned to design, fabricate, and validate an s-CO2 power turbine of nominally 10 MWe that is capable of operation at up to 700°C and operates in a dry-cooled test loop. The project plan consisted of three phases: (1) system design and modeling, (2) fabrication, and (3) testing. The major accomplishments of Phase 1 included: Design of a multistage, axial-flow, s-CO2 power turbine; Design modifications to an existing turbocompressor to provide s-CO2 flow for the test system; Updated equipment and installation costs for the turbomachinery and associated support infrastructure; Development of simulation tools for the test loop itself and for more efficient cycle designs that are of greater commercial interest; Simulation of s-CO2 power cycle …

Civilian Intelligence Community: Additional Actions Needed to Improve Reporting on and Planning for the Use of Contract Personnel (open access)

Civilian Intelligence Community: Additional Actions Needed to Improve Reporting on and Planning for the Use of Contract Personnel

A letter report issued by the Government Accountability Office with an abstract that begins "Limitations in the intelligence community's (IC) inventory of contract personnel hinder the ability to determine the extent to which the eight civilian IC elements--the Central Intelligence Agency (CIA), Office of the Director of National Intelligence (ODNI), and six components within the Departments of Energy, Homeland Security, Justice, State, and the Treasury--use these personnel. The IC Chief Human Capital Officer (CHCO) conducts an annual inventory of core contract personnel that includes information on the number and costs of these personnel. However, GAO identified a number of limitations in the inventory that collectively limit the comparability, accuracy, and consistency of the information reported by the civilian IC elements as a whole. For example, changes to the definition of core contract personnel and data shortcomings limit the comparability of the information over time. In addition, the civilian IC elements used various methods to calculate the number of contract personnel and did not maintain documentation to validate the number of personnel reported for 37 percent of the 287 records GAO reviewed. Further, IC CHCO did not fully disclose the effects of such limitations when reporting contract personnel and cost information …

Constitutional Analysis of Suspicionless Drug Testing Requirements for the Receipt of Governmental Benefits

This report gives an overview of the issues related to federal or state laws that condition the initial or ongoing receipt of governmental benefits on passing drug tests. These regulations are vulnerable to constitutional challenge, most often due to issues of personal privacy and Fourth Amendment protections against "unreasonable searches."

Effect of Phosphate, Fluoride, and Nitrate on Gibbsite Dissolution Rate and Solubility (open access)

Effect of Phosphate, Fluoride, and Nitrate on Gibbsite Dissolution Rate and Solubility

Laboratory tests have been completed with simulated tank waste samples to investigate the effects of phosphate, fluoride, and nitrate on the dissolution rate and equilibrium solubility of gibbsite in sodium hydroxide solution at 22 and 40{degrees}C. Results are compared to relevant literature data and to computer model predictions. The presence of sodium nitrate (3 M) caused a reduction in the rate of gibbsite dissolution in NaOH, but a modest increase in the equilibrium solubility of aluminum. The increase in solubility was not as large, though, as the increase predicted by the computer model. The presence of phosphate, either as sodium phosphate or sodium fluoride phosphate, had a negligible effect on the rate of gibbsite dissolution, but caused a slight increase in aluminum solubility. The magnitude of the increased solubility, relative to the increase caused by sodium nitrate, suggests that the increase is due to ionic strength (or water activity) effects, rather than being associated with the specific ion involved. The computer model predicted that phosphate would cause a slight decrease in aluminum solubility, suggesting some Al-PO4 interaction. No evidence was found of such an interaction.

Federal Workforce: Recent Trends in Federal Civilian Employment and Compensation (open access)

Federal Workforce: Recent Trends in Federal Civilian Employment and Compensation

A letter report issued by the Government Accountability Office with an abstract that begins "From 2004 to 2012, the federal non-postal civilian workforce grew by 258,882 employees, from 1.88 million to 2.13 million (14 percent). Permanent career employees accounted for most of the growth, increasing by 256,718 employees, from 1.7 million in 2004 to 1.96 million in 2012 (15 percent). Three agencies--the Departments of Defense (DOD), Homeland Security (DHS), and Veterans Affairs (VA)--accounted for about 94 percent of this increase. At DOD, officials said that converting certain positions from military to civilian, as well as the growth of the agency's acquisition and cybersecurity workforce, contributed to this overall increase. At VA, officials said the increased demand for medical and health-related services for military veterans drove most of the growth in personnel levels. DHS officials said the increase in employment was due in large part to the nation's border security requirements. (In contrast, ten agencies had fewer career permanent employees in 2012 than they did in 2004). Government-wide, most of the increase in employment from 2004 to 2012 occurred within occupational categories that require higher skill and educational levels. These categories include professional occupations (e.g., doctors and scientists), and administrative occupations …
