YUMMY: The Yucca Mountain MCNP-Library (open access)

YUMMY: The Yucca Mountain MCNP-Library

Point-wise libraries provided with the MCNP code contain neutron data for a limited number of temperatures. However, it is important to have the option of using data from a wide range of temperatures for transport calculations. For this purpose, a multi-temperature, ACE-format neutron library was generated for 134 nuclides, as requested by Yucca Mountain Project (YMP) staff. The library is referred to as YUMMY (YUcca Mountain MCNP-librarY). The neutron cross section data are based on ENDF/B-V or ENDF/B-VI evaluations that were requested by YMP staff. This document provides the details of the new library and its use in criticality safety benchmark problems, a Pressurized Water Reactor design and waste package models in MCNP4C.

Double-shell target design for the NIF: Noncryogenic ignition and nonlinear mix studies for Stockpile Stewardship (open access)

Double-shell target design for the NIF: Noncryogenic ignition and nonlinear mix studies for Stockpile Stewardship

Double-shell ignition is complementary to the baseline approach by virtue of not requiring: (1) cryogenic preparation and fielding, (2) high-contrast pulse-shaping for shock-timing, and (3) demanding x-ray flux symmetry control. The use of simpler low-contrast pulse-shaping potentially allows more benign hohlraum conditions by reducing the risk of laser backscatter. In addition, the associated higher laser fluence threshold for optics damage initiation allows the possibility of more routine high-fluence shots with 2{omega} on the NIF. Based on LDRD-sponsored research in FY01-03 on NIF double-shell ignition target designs, the feasibility of this approach was advanced through both a highly successful implosion campaign on the Omega laser facility and a variety of design improvements for mitigating instability. The double-shell implosion campaign on Omega achieved the important milestone of repeatably demonstrating dominant primary (2.45 MeV) neutron production from the mix-susceptible compressional phase of a double-shell implosion, using fall-line design optimization and exacting fabrication standards. Showing effective control of fuel-pusher mix during final compression is an essential element for achieving ignition. In our studies to control mix by reducing hydrodynamic instability a new pathway for destructive Rayleigh-Taylor growth on the outer surface of the inner shell at ignition scales was identified. However, highly resolved multi-mode …

Identification of Non-Pertechnetate Species In Hanford Tank Waste, Their Synthesis, Characterization, And Fundamental Chemistry (open access)

Identification of Non-Pertechnetate Species In Hanford Tank Waste, Their Synthesis, Characterization, And Fundamental Chemistry

This proposal had three major goals: (1) develop capillary electrophoresis mass spectrometry as a characterization technique, (2) separate a non-pertechnetate fraction from a waste sample and identify the non-pertechnetate species in it by CEMS, and (3) synthesize and characterize bulk quantities of the identified non-pertechnetate species and study their ligand substitution and redox chemistry.

High Level Waste Lag Storage and Feed Blending (open access)

High Level Waste Lag Storage and Feed Blending

SRTC performed small-scale tests to determine the behavior associated with blending streams in the High-level Waste (HLW) Lag Storage and Feed Blending Process System for the Hanford Waste Treatment and Immobilization Plant (WTP). The work reported here was planned and designed in response to the test specification. The Office of River Protection Hanford Waste Treatment and Immobilization Plant consists of three primary facilities: a Pretreatment Facility and two facilities for low-activity and high-level waste vitrification. The Pretreatment Facility contains unit operations which receive waste feed from the Hanford Tank Farms and separate it into two treated waste streams: a low-activity, liquid waste stream stripped of most solids and radioisotopes (processed through the Low-Activity Waste Vitrification Facility) and a high-level waste slurry containing most of the solids and radioisotopes (processed through the High-Level Waste Vitrification Facility). Blending of the later solids a nd radioisotopes streams and their resulting properties is the subject of this report. These mixtures are shown to be unreactive and pumpable by using statistically designed combinations of nonradioactive simulants for the process streams. Properties of the mixtures are also predicted numerically (with the Environmental Simulation Program) and compared with the experimental results. The results did not reveal any …

Stability of High-Level Waste Forms (open access)

Stability of High-Level Waste Forms

The objective of the proposed effort is to use a new approach to develop solution models of complex waste glass systems and spent fuel that are predictive with regard to composition, phase separation, and volatility. The effort will also yield thermodynamic values for waste components that are fundamentally required for corrosion models used to predict the leaching/corrosion behavior for waste glass and spent fuel material. This basic information and understanding of chemical behavior can subsequently be used directly in computational models of leaching and transport in geologic media, in designing and engineering waste forms and barrier systems, and in prediction of chemical interactions.

Managing Tight Binding Receptors for New Spearations Technologies (open access)

Managing Tight Binding Receptors for New Spearations Technologies

Much of the earth's pollution involves compounds of the metallic elements, including actinides, strontium, cesium, technetium, and RCRA metals. Metal ions bind to molecules called ligands, which are the molecular tools that can manipulate the metal ions under most conditions. This DOE-EMSP sponsored program strives (1) to provide the foundations for using the most powerful ligands in transformational separations technologies and (2) to produce seminal examples of their applications to separations appropriate to the DOE EM mission. These ultra tight-binding ligands can capture metal ions in the most competitive of circumstances (from mineralized sites, lesser ligands, and even extremely dilute solutions), but they react so slowly that they are useless in traditional separations methodologies. Two attacks on this problem are underway. The first accommodates to the challenging molecular lethargy by developing a seminal slow separations methodology termed the soil poultice. The second designs ligands that are only tight-binding while wrapped around the targeted metal ion, but can be put in place by switch-binding and removed by switch-release. We envision a kind of molecular switching process to accelerate the union between metal ion and tight-binding ligand. Molecular switching processes are suggested for overcoming the slow natural equilibration rate with which ultra …

Temporary Losses of Highway Capacity and Impacts on Performance: Phase 2 (open access)

Temporary Losses of Highway Capacity and Impacts on Performance: Phase 2

Traffic congestion and its impacts significantly affect the nation's economic performance and the public's quality of life. In most urban areas, travel demand routinely exceeds highway capacity during peak periods. In addition, events such as crashes, vehicle breakdowns, work zones, adverse weather, railroad crossings, large trucks loading/unloading in urban areas, and other factors such as toll collection facilities and sub-optimal signal timing cause temporary capacity losses, often worsening the conditions on already congested highway networks. The impacts of these temporary capacity losses include delay, reduced mobility, and reduced reliability of the highway system. They can also cause drivers to re-route or reschedule trips. Such information is vital to formulating sound public policies for the highway infrastructure and its operation. In response to this need, Oak Ridge National Laboratory, sponsored by the Federal Highway Administration (FHWA), made an initial attempt to provide nationwide estimates of the capacity losses and delay caused by temporary capacity-reducing events (Chin et al. 2002). This study, called the Temporary Loss of Capacity (TLC) study, estimated capacity loss and delay on freeways and principal arterials resulting from fatal and non-fatal crashes, vehicle breakdowns, and adverse weather, including snow, ice, and fog. In addition, it estimated capacity loss …

Canted Undulator Front-End Exit-Mask Flow-Induced Vibration Measurements. (open access)

Canted Undulator Front-End Exit-Mask Flow-Induced Vibration Measurements.

All of the high-heat-load critical components in the new canted-undulator front-end (CU FE) design use wire-coil inserts inside of the cooling channels to significantly enhance heat transfer. Wire-coil inserts have replaced the copper-mesh inserts used in previous front-end high-heat-load critical-component designs. The exit mask, the most downstream component in the CU FE line relative to the x-ray beam path, has an exit aperture of 2 mm vertical x 3 mm horizontal and is the most sensitive component, in terms of final beam stability, of all of the CU FE components. In general, final beam stability is determined by the storage-ring output-beam stability and not by the CU FE components. Although front-end components are not very sensitive to vibration, several measurements have been performed to assess the flow-induced vibration associated with the CU FE exit mask. Results yield only 0.16 {micro}mrms vertical displacement and 1.0 {micro}mrms horizontal displacement under worst-case conditions. The maximum displacement values are very small compared to the aperture size, and therefore flow-induced vibration has a negligible effect on the CU FE output beam stability. More general measurements have also been performed to directly compare flow-induced vibration in an open, unrestricted tube relative to the same tube containing …

Nuclear Fuel Leasing, Recycling and proliferation: Modeling a Global View (open access)

Nuclear Fuel Leasing, Recycling and proliferation: Modeling a Global View

On February 11, 2004, U.S. President George W. Bush, in a speech to the National Defense University stated: ''The world must create a safe, orderly system to field civilian nuclear plants without adding to the danger of weapons proliferation. The world's leading nuclear exporters should ensure that states have reliable access at reasonable cost to fuel for civilian reactors, so long as those states renounce enrichment and reprocessing. Enrichment and reprocessing are not necessary for nations seeking to harness nuclear energy for peaceful purposes.'' This concept would require nations to choose one of two paths for civilian nuclear development: those that only have reactors and those that contain one or more elements of the nuclear fuel cycle, including recycling. ''Fuel cycle'' states would enrich uranium, manufacture and lease fuel to ''reactor'' states and receive the reactor states' spent fuel. All parties would accede to stringent security and safeguard standards, embedded within a newly invigorated international regime. Reactor states would be relieved of the financial, environmental (and political) burden of enriching and manufacturing fuel and dealing with spent fuel. Fuel cycle states would potentially earn money on leasing the fuel and perhaps on sales of reactors to the reactor states. Such …

Project 1: Microbial Genomes: A Genomic Approach to Understanding the Evolution of Virulence. Project 2: From Genomes to Life: Drosophilia Development in Space and Time (open access)

Project 1: Microbial Genomes: A Genomic Approach to Understanding the Evolution of Virulence. Project 2: From Genomes to Life: Drosophilia Development in Space and Time

This project seeks to use the genomes of two close relatives, A. actinomycetemcomitans and H. aphrophilus, to understand the evolutionary changes that take place in a genome to make it more or less virulent. Our primary specific aim of this project was to sequence, annotate, and analyze the genomes of Actinobacillus actinomycetemcomitans (CU1000, serotype f) and Haemophilus aphrophilus. With these genome sequences we have then compared the whole genome sequences to each other and to the current Aa (HK1651 www.genome.ou.edu) genome project sequence along with other fully sequenced Pasteurellaceae to determine inter and intra species differences that may account for the differences and similarities in disease. We also propose to create and curate a comprehensive database where sequence information and analysis for the Pasteurellaceae (family that includes the genera Actinobacillus and Haemophilus) are readily accessible. And finally we have proposed to develop phylogenetic techniques that can be used to efficiently and accurately examine the evolution of genomes. Below we report on progress we have made on these major specific aims. Progress on the specific aims is reported below under two major headings--experimental approaches and bioinformatics and systematic biology approaches.

Shedding New Light on Exploding Stars: Terascale Simulations of Nuetrino-Dreiven Supernovas and Their Nucleosynthesis

Project Abstract This project was a continuation of work begun under a subcontract issued off of TSI-DOE Grant 1528746, awarded to the University of Illinois Urbana-Champaign. Dr. Anthony Mezzacappa is the Principal Investigator on the Illinois award. A separate award was issued to Santa Clara University to continue the collaboration during the time period May 2003 ? 2004. Smolarski continued to work on preconditioner technology and its interface with various iterative methods. He worked primarily with F. Dough Swesty (SUNY-Stony Brook) in continuing software development started in the 2002-03 academic year. Special attention was paid to the development and testing of difference sparse approximate inverse preconditioners and their use in the solution of linear systems arising from radiation transport equations. The target was a high performance platform on which efficient implementation is a critical component of the overall effort. Smolarski also focused on the integration of the adaptive iterative algorithm, Chebycode, developed by Tom Manteuffel and Steve Ashby and adapted by Ryan Szypowski for parallel platforms, into the radiation transport code being developed at SUNY-Stony Brook.

The Deformation-DIA: A Novel Apparatus for Measuring the Strength of Materials at High Strain to Pressures at Elevated Temperature (open access)

The Deformation-DIA: A Novel Apparatus for Measuring the Strength of Materials at High Strain to Pressures at Elevated Temperature

The primary focus of this 3-year project was to develop and put to use an instrument to test experimentally the effect of pressure on body centered cubic (BCC) metals and other materials of interest to the Stockpile Stewardship program. Well-resolved materials testing requires measurements of load and deformation rate be measured at separable conditions of temperature, pressure, and plastic strain. The new apparatus at the heart of this work, the Deformation-DIA (D-DIA), began the project as a design concept. Its principal feature would be the capability to extend the conditions for such controlled materials testing from the current pressure limit of about 3 to almost 15 GPa, a factor of 5 increase. Once constructed and successfully tested, the plan of the project was to deform samples of BCC metals at arbitrary temperature and high pressures in order to provide preliminary measurements of strength and to prove its worth to the Stockpile Stewardship program. The project has been a stunning success. Progress toward demonstrating the worth of the D-DIA as a workhorse instrument for materials strength measurement at high pressure was given a huge boost by the fact that the machine itself functioned flawlessly from the very start, allowing the investigators …

Environmental Protection Issues in the 108th Congress

The 108th Congress has acted on a variety of disparate environmental measures; some of these represent proposals or issues that had been under consideration in the 107th Congress and earlier. Environmental issues considered by Congress tend to fall into several major categories: (1) funding issues — whether funding levels are adequate and focused on appropriate priorities; (2) expanding, renewing, or refocusing specific environment programs; (3) environmental issues that are important “subsets” of other major areas of concern, such as energy, defense, or transportation programs; and more recently, (4) terrorism and infrastructure protection in areas such as wastewater and chemical facilities.
