Nuclear Nonproliferation: U.S. Efforts to Help Other Countries Combat Nuclear Smuggling Need Strengthened Coordination and Planning

Description: A letter report issued by the General Accounting Office with an abstract that begins "The worldwide trafficking and smuggling of nuclear material has reportedly increased in recent years. The International Atomic Energy Agency (IAEA) reports 181 confirmed cases of illicit trafficking of nuclear material since 1993. Many of the cases reported by IAEA involved material that could be used to produce a "dirty bomb" that could spread radioactive contamination over a wide area. Nuclear material can b… more

Workforce Investment Act: Coordination of TANF Services Through One-Stops Has Increased Despite Challenges

Description: Testimony issued by the General Accounting Office with an abstract that begins "A central focus of welfare reform has been to help needy adults with children find and keep jobs. The Workforce Investment Act of 1998 (WIA) unifies a fragmented employment and training system. Despite its similar fundamental focus, the Temporary Assistance for Needy Families (TANF) program was not required to participate in the one-stop system, although many states are coordinating their TANF services through one-s… more

Energy Efficiency Standards and Labels in North America: Opportunities for Harmonization

Description: To support the North American Energy Working Group's Expert Group on Energy Efficiency (NAEWG-EE), USDOE commissioned the Collaborative Labeling and Appliance Standards Program (CLASP) to prepare a resource document comparing current standards, labels, and test procedure regulations in Canada, Mexico, and the United States. The resulting document reached the following conclusions: Out of 24 energy-using products for which at least one of the three countries has energy efficiency regulations, th… more

Measurement Issues for Energy Efficient Commercial Buildings: Productivity and Performance Uncertainties

Description: In previous reports, we have identified two potentially important issues, solutions to which would increase the attractiveness of DOE-developed technologies in commercial buildings energy systems. One issue concerns the fact that in addition to saving energy, many new technologies offer non-energy benefits that contribute to building productivity (firm profitability). The second issue is that new technologies are typically unproven in the eyes of decision makers and must bear risk premiums that… more

Energy Efficiency, Building Productivity and the Commercial Buildings Market

Description: The energy-efficiency gap literature suggests that building buyers are often short-sighted in their failure to apply life-cycle costing principles to energy efficient building technologies, with the result that under investment in these advanced technology occurs. This study examines the reasons this behavior may occur, by analyzing the pressures that market forces place on purchasers of buildings. Our basic conclusion is that the fundamental manner in which the buildings sector does business c… more

Electroproduction of strangeness on light nuclei.

Description: The A(e,e{prime} K{sup +})YX reaction has been investigated in Hall C at Jefferson Laboratory for 6 different targets. Data were taken for Q{sup 2} {approx} 0.35 and 0.5 GeV{sup 2} at a beam energy of 3.245 GeV for {sup 1}H, {sup 2}H, {sup 3}He, {sup 4}He, C and Al targets. The missing mass spectra are fitted with Monte Carlo simulations taking into account the production of {Lambda} and {Sigma}{sup 0} hyperon production off the proton, and {Sigma}{sup -} off the neutron. Models for quasifree p… more

Are recoil polarization measurements of G{sup P}{ovr sub E}/G{sup P}{ovr sub M} consistent with Rosenbluth separation data?

Description: Recent recoil polarization measurements in Hall A at Jefferson Lab show that the ratio of the electric to magnetic form factors for the proton decreases significantly with increasing Q{sup 2}. This contradicts previous Rosenbluth measurements which indicate approximate scaling of the form factors ({micro}{sub p} G{sub E}{sup p}(Q{sup 2})/G{sub M}{sup p} (Q{sup 2}) {approx} 1). The cross section measurements were reanalyzed to try and understand the source of this discrepancy. They find that the… more

Expanding the Allowable TRUPACT-II Payload

Description: The partnership between the Carlsbad Field Office (CBFO) and the TRU and Mixed Waste Focus Area (TMFA) was rewarded when several long-term projects came to fruition. The Nuclear Regulatory Commission (NRC) removed some of the conservatism in the TRUPACT-II Safety Analysis Report for Packaging (SARP) with their approval of Revision 19. The SARP strictly limits the payload constituents to ensure that hydrogen gas and other flammable volatile organic compounds (VOCs) don't build up to flammable/ex… more

Securing collaborative environments

Description: The diverse set of organizations and software components involved in a typical collaboratory make providing a seamless security solution difficult. In addition, the users need support for a broad range of frequency and locations for access to the collaboratory. A collaboratory security solution needs to be robust enough to ensure that valid participants are not denied access because of its failure. There are many tools that can be applied to the task of securing collaborative environments and t… more

Opportunities for Catalysis in The 21st Century. A report from the Basic Energy Sciences Advisory Committee

Description: Chemical catalysis affects our lives in myriad ways. Catalysis provides a means of changing the rates at which chemical bonds are formed and broken and of controlling the yields of chemical reactions to increase the amounts of desirable products from these reactions and reduce the amounts of undesirable ones. Thus, it lies at the heart of our quality of life: The reduced emissions of modern cars, the abundance of fresh food at our stores, and the new pharmaceuticals that improve our health are … more

Improving exchange-spring magnets with interfacial modification.

Description: Using magnetic thin film multilayers as model exchange-spring systems proves to be the promising intellectual path that helps generate the mechanistic and materials insights needed to create high-performance permanent magnet materials. We demonstrate a new route to improve exchange-spring magnets whereby the hard/soft interface in epitaxial Sm-Co/Fe and Sm-Co/Co bilayer thin film structures is modified via thermal processing. The effect of thermal processing is modeled with a graded interfacial… more

Increased Efficiencies in the INEEL SAR/TSR/USQ Process

Description: The Idaho National Engineering and Environmental Laboratory (INEEL) has implemented a number of efficiencies to reduce the time and cost of preparing safety basis documents. The INEEL is continuing to look at other aspects of the safety basis process to identify other efficiencies that can be implemented and remain in compliance with Title 10 Code of Federal Regulations (CFR) Part 830. A six-sigma approach is used to identify areas to improve efficiencies and develop the action plan for impleme… more

Making Energy-Efficiency and Productivity Investments in Commercial Buildings: Choice of Investment Models

Description: This study examines the decision to invest in buildings and the types of investment decision rules that may be employed to inform the ''go--no go'' decision. There is a range of decision making tools available to help in investment choices, which range from simple rules of thumb such as payback periods, to life-cycle analysis, to decision theoretic approaches. Payback period analysis tends to point toward lower first costs, whereas life-cycle analysis tends to minimize uncertainties over future… more

Monte Carlo Evaluation of the Improvements in Nuclear Materials Identification System (NMIS) Resulting From a DT Neutron Generator

Description: Nuclear safeguards active measurements that rely on the time correlation between fast neutrons and gamma rays from the same fission are a promising technique. Previous studies have shown the feasibility of this method, in conjunction with the use of artificial neural networks, to estimate the mass and enrichment of fissile samples enclosed in special, sealed containers. This paper evaluates the use of the associated particle sealed tube neutron generator (APSTNG) as the interrogation source in … more
