EXTRACTION OF NEPTUNIUM FROM ACIDIC SOLUTIONS BY ORGANIC NITROGEN AND PHOSPHORUS COMPOUNDS (open access)

EXTRACTION OF NEPTUNIUM FROM ACIDIC SOLUTIONS BY ORGANIC NITROGEN AND PHOSPHORUS COMPOUNDS

Neptunium distribution coefficients from acid nitrate, chloride, and sulfate solutions by several organic nitiogen and phosphorus compounds were measured as functions of several extraction variables, including neptunium valence, acid and salt concentration, and reagent concentration. Extractability by all the reagents varied in the order Np(IV)> Np(VI)>> Np(V). Except for primary amines, all reagents extracted Np(IV) much more strongly from nitrate than sulfate solutions. Among organonitrogen compounds the order of extractability of Np(IV) was: quaternary> tertiary> primary and secondary from nitrate solutions but primary>> secondary> tertiary from sulfate solutions. Neptunium(IV) nitrate extractions with the different extractants passed through maxima at widely different acid concentrations. In most cases, extraction increased when nitric acid was replaced by nitrate salt. Extraction was usually approximately proportional to the square of the reagent concentration. (auth)

Low Temperature Thermoluminescence of Gamma Irradiated Potassium Dihydrogen Phosphate (open access)

Low Temperature Thermoluminescence of Gamma Irradiated Potassium Dihydrogen Phosphate

Thermoluminescence in potassium dihydrogen phosphate (KDP) induced by Co/ sup 60/ gamma irradiation at liquid nitrogen temperature (-198 deg C) was investigated. Glow curves in the temperature range --196 to 0 deg C were measured for a series of gamma exposure dosages ranging from 10/sup 4/ roentgen to 5 x 10/sup 6/ roentgen. The heating rate used for glow curve measurements was 12 deg C per minute. Twice recrystallized Mallinckrodt reagent grade potassium dihydrogen phosphate, with a grain size between 100 and 170 mesh, was used for most samples. In the case of the powder samples, the glow curve for an exposure dose of 10/sup 4/ roentgen exhibited two peaks in this temperature range, one at approximately --78 deg C and the other at approximately -146 deg C. The -78 deg C peak split into two distinct peaks with increasing dosage. At still higher doses an additional peak at about -9 deg C became evident. This peak may, however, be due to aluminum oxide. Calculation of the trap depth, E, and the frequency factor, s, associated with the --78 deg C peak, by the approximate method of Grossweiner yielded values of 0.485 ev and 9.97 x 10/sup 10/ sec/sup -1/ …

INFLUENCE OF RADIATION FROM AN UNSHIELDED REACTOR ON A NATURAL MICROFLORA (open access)

INFLUENCE OF RADIATION FROM AN UNSHIELDED REACTOR ON A NATURAL MICROFLORA

The soil microflora and its respiratory activity were measured in soil cores collected at different distances from an unshielded reactor. No direct correlation was found between dose received and microbial counts or respiration. Indication of a correlation between dose and microbial respiration was obtained after eliminating the overriding influence of moisture. Radiation probably affected the soil microflora through damage to the phanerogam vegetation rather than directly. This preliminary study indicates the need to have undisturbed sampling areas close to the ORNL fast burst reactor. Extensive dosimetry, both in and above the soil, in these areas, and a program of long-term ecological descriptibn, should be started before the reactor becomes operational. (auth)

Ion-beam inertial fusion: the requirements posed by target and deposition physics (open access)

Ion-beam inertial fusion: the requirements posed by target and deposition physics

The demonstration of ICF scientific feasibility requires success in target design, driver development and target fabrication. Since these are interrelated, we present here some results of ion beam target studies and relate them to parameters of interest to ion accelerators. Ion deposition physics have long been a well known subject apart from high beam currents. Recent NRL experiments at up to 250 kA/cm/sup 2/ ions confirm the classical deposition physics now at current densities which are comparable to most ion targets. On the other hand, GSI data at low current density but 1 to 10 MeV/nucleon are continually being accumulated. They have yet to find anomalous results. Relying on target concepts outlined briefly, we report on the energy gain of ion-driven fusion targets as a function of input energy, ion ranges and focal spot radius. We also comment on some consequences of target gain versus driver and reactor requirements.

Delay line proportional chambers for the Fermilab external muon identifier (open access)

Delay line proportional chambers for the Fermilab external muon identifier

Thirty-nine one meter square proportional chambers with delay line readout were constructed for the external muon identifier of the Fermilab 15 foot bubble chamber. They provide X,Y,U(45/sup 0/) and T (avalanche time) information using a single wire plane, etched strip cathodes and nine amplifiers. They have a time resolution of +-27ns, single particle spatial resolution of +-2 to +-3mm and double particle resolution of approximately 2/sup 1///sub 2/ to 4cm. The energy accessible to each wire is limited so none of the wires in the first 25 chambers has broken since their installation in 1973 to 1974.

for filtration of plutonium oxalate slurries. A scalpel produces a slit in the filter precoat, leading to increased filtration in this slit, and the oxalate is removed by a doctor knife; this technique results in prolonged blowback cycles and more uniform delivery of filtered oxalate to subsequent processing steps. Several types of filter media were tested, and rigid porous aluminum oxide was found to be the best one. (D.L.C.)

Southwest Border: More Timely Border Patrol Access and Training Could Improve Security Operations and Natural Resource Protection on Federal Lands

A letter report issued by the Government Accountability Office with an abstract that begins "Over the last 5 years, Border Patrol has nearly doubled the number of its agents on patrol, constructed hundreds of miles of border fence, and installed surveillance equipment on and near lands managed by the Departments of the Interior and Agriculture along the southwestern border. In so doing, the agency has had to comply with federal land management laws, and some have expressed concern that these laws may limit agents' abilities to detect and apprehend undocumented aliens. GAO was asked to examine (1) key land management laws Border Patrol operates under and how it and land management agencies coordinate their responsibilities under these laws; (2) how Border Patrol operations are affected by these laws; and (3) the extent to which land management agencies collect and use data related to the environmental effects of illegal activities, such as human trafficking and drug smuggling. GAO reviewed key land management laws, interviewed agents-in-charge at 26 Border Patrol stations responsible for patrolling federal southwest borderlands, and interviewed managers of these lands."

Defense Health Care: Health Insurance Stipend Program Expected to Cost More Than TRICARE But Could Improve Continuity of Care for Dependents of Activated Reserve Component Members

Correspondence issued by the Government Accountability Office with an abstract that begins "Since the September 11, 2001, terrorist attacks, the Department of Defense (DOD) has increased its reliance on its National Guard and reserve forces to support the Global War on Terrorism, and particularly Operation Iraqi Freedom. Congress has been interested in making improvements and enhancements to compensation and benefit programs for reserve component members. When reserve component members are activated for more than 30 days under federal authorities, they are covered under TRICARE, DOD's health care system. While reserve component members are automatically covered by TRICARE when activated, their spouses and other dependents have the option of using either TRICARE or their private health insurance. However, our prior work found that dependents of reserve component members who had dropped their private health insurance reported problems accessing the TRICARE system--such as difficulty finding a health care provider, establishing eligibility, understanding TRICARE benefits, and knowing where to go when questions and problems arise. In addition, maintaining continuity of care with the same health care providers, especially for dependents with chronic medical conditions, may be problematic after switching to TRICARE. To address these concerns, some legislative proposals would give reserve component members …

Piracy: A Legal Definition (open access)

Piracy: A Legal Definition

Pirate attacks in the waters off the Horn of Africa, including those on U.S.-flagged vessels, have brought continued U.S. and international attention to the long-standing problem of piracy in the region. A recent development in one of the piracy trials in Norfolk, VA, has highlighted a potential limitation in the definition of piracy under the United States Code. This report first examines the historical development of the offense of piracy, as defined by Congress and codified in the United States Code. The focus then turns to how contemporary international agreements define piracy. Finally, the report highlights a recent federal district court ruling that the offense of piracy under 18 U.S.C. § 1651 requires a robbery at sea.

VA Community Living Centers: Actions Needed to Better Manage Risks to Veterans' Quality of Life and Care

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Veterans Affairs (VA) annually provides care to more than 46,000 elderly and disabled veterans in 132 VA-operated nursing homes, called community living centers (CLC). After media reports of problems with the care delivered to veterans in CLCs, VA contracted with the Long Term Care Institute, Inc. (LTCI), a nonprofit organization that surveys nursing homes, to conduct in-depth reviews of CLCs in 2007-2008 and again in 2010-2011. GAO was asked to evaluate VA's approach to managing veterans' quality of care and quality of life in CLCs. This report examines (1) VA's response to and resolution of LTCI-identified deficiencies and (2) information VA collects about the quality of care and quality of life in CLCs and how VA uses it to identify and manage risks. To do this work, GAO interviewed officials from VA headquarters, examined all 116 2007-2008 and 67 2010-2011 LTCI reviews, and analyzed 50 CLCs' corrective action plans for 2007-2008 and 23 such plans for 2010-2011."

Military Training: DOD's Report on the Sustainability of Training Ranges Meets Annual Reporting Requirements but Could Be Improved

Correspondence issued by the Government Accountability Office with an abstract that begins "Realistic training ranges are one of the most valued assets the military has in preparing its personnel for their missions. Realistic training requires access to areas and environments that closely match the locations where the military may face combat or complex situations. International events, changes in strategy, force structure, base closures, and population growth are increasing the challenges the military faces in training its personnel to be prepared to defend the nation. Moreover, the military services report that they have increasingly lost training range capabilities because of factors such as encroachment. To respond to these challenges and increase the sustainability of military ranges, the Department of Defense (DOD) has launched a number of efforts aimed at preserving training ranges while also minimizing adverse environmental effects of training activities. As required by section 366(a) of the Bob Stump National Defense Authorization Act for Fiscal Year 2003 (as amended), DOD was to submit a comprehensive plan for using existing authorities available to the department to address training constraints caused by limitations on the use of worldwide military lands, marine areas, and airspace to Congress at the same time as the …

Surface Coal Mining: Information on Clean Water Act Section 404 Permit Reviews under Enhanced Coordination Procedures in Appalachia, Focusing on West Virginia

Correspondence issued by the Government Accountability Office with an abstract that begins "In 2009, West Virginia accounted for about 43 percent of the surface coal mining production in Appalachia. Surface coal mining in the mountainous areas of Appalachia--a process often referred to as mountaintop mining--has generated opposition in recent years because of its impact on landscapes, streams, ecosystems, and communities. In mountaintop mining, before the underlying coal can be extracted, the land is cleared of forest and other vegetation. Explosives or other techniques are then used to break up the overlying solid rock, creating dislodged earth, rock, and other materials known as "spoil." Some or most of the spoil is placed back on the mined-out area; however, spoil that cannot be safely placed back is often placed as "fill" in adjacent valleys or hollows. In some cases, this fill buries the headwaters of streams. Activities associated with surface coal mining are regulated under both the Surface Mining Control and Reclamation Act (SMCRA) and the Clean Water Act (CWA).3 SMCRA requires mine operators to obtain a permit before they begin mining. In West Virginia, the West Virginia Department of Environmental Protection (WVDEP) administers the SMCRA permit program, subject to the Department …
