Fuel cycle methods : first-order spherical harmonics formulations capable of treating low density regions.

Description: In this report we present an approach to deal with a problem encountered in different type of systems and specific configurations: the treatment of low density regions. This is the case of gas cooled reactors, voided configurations (evaluations of associated reactivity coefficients), beam region of external source driven systems, etc. The approach is to form the nodal response matrix using the first-order form of the transport equation, for then the cross section no longer appears in the denomi… more

FY03 DNAPL Characterization of the A-14 Outfall

Description: Residual dense non-aqueous phase liquid (DNAPL) contamination continues to be one of the most challenging remediation and characterization problems at SRS and sites around the world. Chlorinated solvents were usually released as DNAPLs to/the subsurface where they move in an unstable fashion driven by gravitational and,capillary forces. They are often retained in small discrete blobs in fine grain materials in the vadose zone and contaminate ground water by slow continuous release through disso… more

User's guide, version 1 RESRAD-BIOTA : a tool for implementing a graded approach to biota dose evaluation.

Description: This Interagency Steering Committee on Radiation Standards (ISCORS) Technical Report provides a User's Guide for the RESRAD-BIOTA code. The RESRAD-BIOTA code is a tool for implementing a graded approach to biota dose evaluation. The RESRAD-BIOTA code was principally sponsored and developed by the U.S. Department of Energy (DOE), with support from the U.S. Environmental Protection Agency (EPA) and the U.S. Nuclear Regulatory Commission (NRC), through the informal interagency Ecological Radiologi… more

Investigation of the Rayleigh-Taylor and Richtmyer-Meshkov instabilities

Description: Some of the major difficulties encountered in the effort to achieve nuclear fusion by means of inertial confinement arise from the unstable behavior of the interface between the shell material and the nuclear fuel which develops upon implosion of the shell by direct or indirect laser drive. The fluid flows that develop (termed the Rayleigh-Taylor (RT) and the Richtmyer-Meshkov (RM) instabilities) cause the gassified shell material to mix with the nuclear fuel, causing a reduction in energy yiel… more

A Hydro-Economic Approach to Representing Water Resources Impacts in Integrated Assessment Models

Description: Grant Number DE-FG02-98ER62665 Office of Energy Research of the U.S. Department of Energy Abstract Many Integrated Assessment Models (IAM) divide the world into a small number of highly aggregated regions. Non-OECD countries are aggregated geographically into continental and multiple-continental regions or economically by development level. Current research suggests that these large scale aggregations cannot accurately represent potential water resources-related climate change impacts. In addit… more

NARAC Products File Description Version 2.1

Description: The National Atmospheric Release Advisory Center (NARAC) Products File is primarily used to transmit information about an atmospheric release calculation (a run) done on NARAC's centralized system to end user tools such as the NARAC iClient and the NARAC Web. This Products File uses the eXtensible Markup Language (XML) to store this information. Normally, the name of this file is products.xml. This document describes the structure and content of this products.xml file.

Dissolution of Highly Enriched Uranium from the Idaho National Engineering and Environmental Laboratory

Description: Since the capability to purify uranium (U) was terminated at the Idaho National Engineering and Environmental Laboratory (INEEL) in the early 1990's, excess highly enriched uranium (HEU) from the cleanout of uranium trioxide (UO3) production equipment will be shipped to the Savannah River Site (SRS) for disposition. The excess material will be dissolved in Phase I of HB-Line, purified by solvent extraction, and blended with normal U to an enrichment which can be used to fabricate fuel for Tenne… more

Clean Air and New Source Review: Defining Routine Maintenance

Description: The Environmental Protection Agency (EPA) final rule on clarifying the definition of routine maintenance under its New Source Review (NSR) process exempts industrial facilities from undergoing NSR if they are replacing safety, reliability, and efficiency rated components with new, functionally equivalent equipment and if the cost of the replacement components is under 20 percent of the replacement value of the process unit.
