The First Responder Network and Next- Generation Communications for Public Safety: Issues for Congress

Since September 11, 2001, when communications failures contributed to the tragedies of the day, Congress has passed several laws intended to create a nationwide emergency communications capability. Yet the United States has continued to strive for a solution that assures seamless communications among first responders and emergency personnel at the scene of a major disaster. To address this problem, Congress included provisions in the Middle Class Tax Relief and Job Creation Act of 2012 (P.L. 112-96) for planning, building, and managing a new, nationwide, broadband network for public safety communications, and assigned additional spectrum to accommodate the new network.

Managing Critical Isotopes: DOE's Isotope Program Needs Better Planning for Setting Prices and Managing Production Risks (open access)

Managing Critical Isotopes: DOE's Isotope Program Needs Better Planning for Setting Prices and Managing Production Risks

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Energy’s (DOE) Isotope Development and Production for Research and Applications program (Isotope Program) provides over 300 different isotopes for commercial and research applications. The Isotope Program is responsible for 243 stable isotopes that are no longer produced in the United States but are sold from the program’s existing inventory and for 55 radioactive isotopes, called radioisotopes, that the program is able to produce at DOE facilities. An additional 10 isotopes sold by the Isotope Program are provided by the National Nuclear Security Administration (NNSA), a separate agency within DOE, as by-products of its nuclear weapons program."

Military Disability System: Preliminary Observations on Efforts to Improve Performance (open access)

Military Disability System: Preliminary Observations on Efforts to Improve Performance

Testimony issued by the Government Accountability Office with an abstract that begins "Case processing times under the Integrated Disability Evaluation System (IDES) process have increased over time, and measures of servicemember satisfaction have shortcomings. Each year, average processing time for IDES cases has climbed, reaching 394 and 420 days for active and reserve component members in fiscal year 2011—well over established goals of 295 and 305 days, respectively. Also in fiscal year 2011, just 19 percent of active duty servicemembers and 18 percent of guard or reserve members completed the IDES process and received benefits within established goals, down from 32 and 37 percent one year prior. Of the four phases comprising IDES, the medical evaluation board phase increasingly fell short of timeliness goals and, within that phase, the time required for the military’s determination of fitness was especially troubling. During site visits to IDES locations, we consistently heard concerns about timeframes and resources for this phase of the process. With respect to servicemember satisfaction with the IDES process, GAO found shortcomings in how these data are collected and reported, such as unduly limiting who is eligible to receive a survey and computing average satisfaction scores in a manner that …

Experimental Study of Parametric Dependence of Electron-scale Turbulence in a Spherical Tokamak (open access)

Experimental Study of Parametric Dependence of Electron-scale Turbulence in a Spherical Tokamak

Electron-scale turbulence is predicted to drive anomalous electron thermal transport. However, experimental study of its relation with transport is still in its early stage. On the National Spherical Tokamak eXperiment (NSTX), electron-scale density fluctuations are studied with a novel tangen- tial microwave scattering system with high radial resolution of ±2 cm. Here, we report a study of parametric dependence of electron-scale turbulence in NSTX H-mode plasmas. The dependence on density gradient is studied through the observation of a large density gradient variation in the core induced by an ELM event, where we found the first clear experimental evidence of density gradient stabilization of electron-gyro scale turbulence in a fusion plasma. This observation, cou- pled with linear gyro-kinetic calculations, leads to the identification of the observed instability as toroidal Electron Temperature Gradient (ETG) modes. It is observed that longer wavelength ETG modes, k⊥ρs < 10 (ρs is the ion gyroradius at electron temperature and k⊥ is the wavenumber perpendicular to local equilibrium magnetic field), are most stabilized by density gradient, and the stabilization is accompanied by about a factor of two decrease in electron thermal diffusivity. Comparisons with nonlinear ETG gyrokinetic simulations shows ETG turbulence may be able to explain the …

Uranium Enrichment Standards of the Y-12 Nuclear Detection and Sensor Testing Center (open access)

Uranium Enrichment Standards of the Y-12 Nuclear Detection and Sensor Testing Center

The Y-12 National Security Complex has recently fabricated and characterized a new series of metallic uranium standards for use in the Nuclear Detection and Sensor Testing Center (NDSTC). Ten uranium metal disks with enrichments varying from 0.2 to 93.2% {sup 235}U were designed to provide researchers access to a wide variety of measurement scenarios in a single testing venue. Special care was taken in the selection of the enrichments in order to closely bracket the definitions of reactor fuel at 4% {sup 235}U and that of highly enriched uranium (HEU) at 20% {sup 235}U. Each standard is well characterized using analytical chemistry as well as a series of gamma-ray spectrometry measurements. Gamma-ray spectra of these standards are being archived in a reference library for use by customers of the NDSTC. A software database tool has been created that allows for easier access and comparison of various spectra. Information provided through the database includes: raw count data (including background spectra), regions of interest (ROIs), and full width half maximum calculations. Input is being sought from the user community on future needs including enhancements to the spectral database and additional Uranium standards, shielding configurations and detector types. A related presentation are planned …

METAL MEDIA FILTERS, AG-1 SECTION FI (open access)

METAL MEDIA FILTERS, AG-1 SECTION FI

One application of metal media filters is in various nuclear air cleaning processes including applications for protecting workers, the public and the environment from hazardous and radioactive particles. To support this application the development of the ASME AG-1 FI Standard on Metal Media has been under way for more than ten years. Development of the proposed section has required resolving several difficult issues associated with operating conditions (media velocity, pressure drop, etc.), qualification testing, and quality acceptance testing. Performance characteristics of metal media are dramatically different than the glass fiber media with respect to parameters like differential pressures, operating temperatures, media strength, etc. These differences make existing data for a glass fiber media inadequate for qualifying a metal media filter for AG-1. In the past much work has been conducted on metal media filters at facilities such as Lawrence Livermore National Laboratory (LLNL) and Savannah River National Laboratory (SRNL) to qualify the media as High Efficiency Particulate Air (HEPA) Filters. Particle retention testing has been conducted at Oak Ridge Filter Test Facility and at Air Techniques International (ATI) to prove that the metal media meets or exceeds the 99.97% particle retention required for a HEPA Filter. Even with his testing, …

Changes to MFRSRCLDOD1MIN Datastream (open access)

Changes to MFRSRCLDOD1MIN Datastream

Significant updates were made to the multifilter rotating shadowband radiometer (MFRSR) cloud optical depth (MFRSRCLDOD) value-added product (VAP) in 2011. The original intent of the update was to add quality control (QC) flags and to update the VAP to use the improved retrievals of liquid water path (LWP) from the Microwave Radiometer Retrievals (MWRRET) VAP rather than the statistical retrievals of LWP from the Microwave Radiometer Line of Sight (MWRLOS) datastream. Although this was originally intended to be a straightforward update of the code, it became more complicated due to the following factors: (1) a new developer and translator team were working with the code; (2) numerous small changes had to be made to the code to consistently implement the QC flags; and (3) ARM standards have changed over the years since the code was originally developed.
