Alternative Fuels and Advanced Technology Vehicles: Issues in Congress

Description: Alternative fuels and advanced technology vehicles are seen by proponents as integral to improving urban air quality, decreasing dependence on foreign oil, and reducing emissions of greenhouse gases. However, major barriers—especially economics—currently prevent the widespread use of these fuels and technologies. The 112th Congress has debated alternative fuels and advanced technology vehicles directly and as it has addressed other key topics. On June 16, 2011 the Senate approved S.Amdt. 476 wh… more

Alternative Inspection Methods for Single Shell Tanks

Description: This document was prepared to provide evaluations and recommendations regarding nondestructive evaluation methods that might be used to determine cracks and bowing in the ceiling of waste storage tanks on the Hanford site. The goal was to determine cracks as small as 1/16 in. wide in the ceiling, and bowing as small as 0.25 in. This report describes digital video camera methods that can be used to detect a crack in the ceiling of the dome, and methods for determining the surface topography of t… more

Amine Extraction of Plutonium From Nitric Acid Solutions Loading and Stripping Experiments

Description: Information is presented on a suitable amine processing system for plutonium nitrate. Experiments with concentrated plutonium nitrate solutions show that trilaurylamine (TLA) - xylene solvent systems did not form a second organic phase. Experiments are also reported with tri-noctylamine (TnOA)-xylene and TLA-Amsco - octyl alcohol. Two organic phases appear in both these systems at high plutonium nitrate concentrations. Data are tabulated from loading and stripping experiments. (J.R.D.)

Amtrak and Energy Conservation: Background and Selected Public Policy Issues

Description: A rationale for federal financial support to Amtrak has been that rail service conserves energy, compared to other forms of intercity passenger transportation. The numbers discussed in this report suggest that the rationale might not be valid with regard to autos and buses. The report discusses some public policy implications that could follow from that conclusion.

Analysis of Base-Case Particle Tracking Results of the Base-Case Flow Fields (ID:U0160)

Description: The purpose of this analysis is to provide insight into the unsaturated-zone (UZ) subsystem performance through particle tracking analyses of the base-case flow fields. The particle tracking analyses will not be used directly in total-system performance-assessment (TSPA) calculations per se. The objective of this activity is to evaluate the transport of radionuclides through the unsaturated zone and to determine how different system parameters such as matrix diffusion, sorption, water-table ris… more

Analysis of Limitations Imposed on One-Spool Turbojet-Engine Designs by Turbines Having Downstream Stators at 0, 2.0, and 2.8 Flight Mach Numbers

Description: Memorandum presenting an aerodynamic design-point analysis of one-spool turbojet engines with one-stage turbines with one and with two rows of downstream stator blades. The object of the analysis was to evaluate the design characteristics of the turbines in comparison with conventional one- and two-stage turbines, to determine the extent to which exit whirl can be increased before causing weight-flow capacity to decrease, and to determine the effect of downstream stators on engine design limita… more

Analytical Radiation Transport Benchmarks for The Next Century

Description: Verification of large-scale computational algorithms used in nuclear engineering and radiological applications is an essential element of reliable code performance. For this reason, the development of a suite of multidimensional semi-analytical benchmarks has been undertaken to provide independent verification of proper operation of codes dealing with the transport of neutral particles. The benchmarks considered cover several one-dimensional, multidimensional, monoenergetic and multigroup, fixe… more

Analytical theory of ion-temperature-gradient instability

Description: The relationship between the threshold values of ion-temperature-gradient instabilities and the temperature parameters of plasmas is investigated analytically in slab and toroidal geometries separately. It is found that the threshold values increase rapidly when the ion temperature becomes much higher than the electron temperature. The change of the threshold vaues with respect to the ion temperature is quite similar for both geometric models. This finding is consistent with PLT observations. F… more

Description: The RAR/SAR is a high-priority radar system for the joint US/UK Program. Based on previous experiment results and coordination with the UK, specifications needed for future radar experiments were identified as follows: dual polarimetric (HH and VV) with medium to high resolution in SAR mode. Secondary airborne installation requirements included; high power (circa 10kw) and SLIER capability to emulate Tupelev-134 type system; initially x-band but easily extendible to other frequencies. In FY96 w… more

Assessing the Effects of Radiation Damage on Ni-base Alloys for the Prometheus Space Reactor System

Description: Ni-base alloys were considered for the Prometheus space reactor pressure vessel with operational parameters of {approx}900 K for 15 years and fluences up to 160 x 10{sup 20} n/cm{sup 2} (E > 0.1 MeV). This paper reviews the effects of irradiation on the behavior of Ni-base alloys and shows that radiation-induced swelling and creep are minor considerations compared to significant embrittlement with neutron ,exposure. While the mechanism responsible for radiation-induced embrittlement is not f… more

Atomistic simulation of point defects and dislocations in bbc transition metals from first principles

Description: Using multi-ion interatomic potentials derived from first-principles generalized pseudopotential theory, we have been studying point defects and dislocations in bcc transition metals, with molybdenum (Mo) as a prototype. For point defects in Mo, the calculated vacancy formation and activation energies are in excellent agreement with experimental results. The energetics of six self-interstitial configurations in Mo have also been investigated. The <110> split dumb-bell is found to have the lowes… more

Automobile and Light Truck Fuel Economy: The CAFE Standards

Description: On April 6, 2006, the National Highway Traffic Safety Administration (NHTSA) released a final rulemaking for sport utility vehicles (SUVs) and light duty trucks beginning with model year (MY) 2008. The rule restructures the Corporate Average Fuel Economy (CAFE) program for light trucks to establish standards based upon vehicle size, as opposed to the current program with one average standard for all light trucks. It marks a significant change to the CAFE program for trucks.
