Control Decisions for Flammable Gas Hazards in Waste Transfer Systems

Description: This report describes the control decisions for flammable gas hazards in waste transfer systems (i.e., waste transfer piping and waste transfer-associated structures) made at control decision meetings on November 30, 1999a and April 19, 2000, and their basis. These control decisions, and the analyses that support them, will be documented in an amendment to the Final Safety Analysis Report (FSAR) (CHG 2000a) and Technical Safety Requirements (TSR) (CHG 2000b) to close the Flammable Gas Unreviewe… more

Inorganic, radioisotopic and organic analysis of 241-AP-101 tank waste

Description: Battelle received five samples from Hanford waste tank 241-AP-101, taken at five different depths within the tank. No visible solids or organic layer were observed in the individual samples. Individual sample densities were measured, then the five samples were mixed together to provide a single composite. The composite was homogenized and representative sub-samples taken for inorganic, radioisotopic, and organic analysis. All analyses were performed on triplicate sub-samples of the composite ma… more

Midwest Gasoline Prices: A Review of Recent Market Developments

Description: This report provides background information regarding the especially high gasoline prices in the upper Midwest during the late spring and early summer of 2000. While the Federal Trade Commission is investigating the possibility of collusion, several identifiable factors have contributed to this localized situation. Contributors to the higher prices appear to be problems at two pipelines supplying the area with gasoline, the use of ethanol-only reformulated gasoline in Chicago and Milwaukee, and… more

Repository Closure and Sealing Approach

Description: The scope of this analysis will be to develop the conceptual design of the closure seals and their locations in the Subsurface Facilities. The design will be based on the recently established program requirements for transitioning to the Site Recommendation (SR) design as outlined by ''Approach to Implementing the Site Recommendation Baseline'' (Stroupe 2000) and the ''Monitored Geologic Repository Project Description Document'' (CRWMS M&O 1999b). The objective of this analysis will be to a… more

Site Recommendation Subsurface Layout

Description: The purpose of this analysis is to develop a Subsurface Facility layout that is capable of accommodating the statutory capacity of 70,000 metric tons of uranium (MTU), as well as an option to expand the inventory capacity, if authorized, to 97,000 MTU. The layout configuration also requires a degree of flexibility to accommodate potential changes in site conditions or program requirements. The objective of this analysis is to provide a conceptual design of the Subsurface Facility sufficient to … more

Studies of tritiated co-deposited layers in TFTR

Description: Plasma facing components in TFTR contain an important record of plasma wall interactions in reactor grade DT plasmas. Tiles, flakes, wall coupons, a stainless steel shutter and dust samples have been retrieved from the TFTR vessel for analysis. Selected samples have been baked to release tritium and assay the tritium content. The in-vessel tritium inventory is estimated to be 0.56 g and is consistent with the in-vessel tritium inventory derived from the difference between tritium fueling and tr… more

Support Services for Ceramic Fiber-Ceramic Matrix Composites

Description: Structural and functional materials used in solid- and liquid-fueled energy systems are subject to gas- and condensed-phase corrosion and erosion by entrained particles. For a given material, its temperature and the composition of the corrodents determine the corrosion rates, while gas flow conditions and particle aerodynamic diameters determine erosion rates. Because there are several mechanisms by which corrodents deposit on a surface, the corrodent composition depends not only on the composi… more

Antiproton and electron optics for electron cooling

Description: Optical issues for electron cooling in the Recycler are discussed. An optimal value of the antiproton beta-function depends on the cooling purposes (longitudinal or transverse), on the antiproton emittances and the energy spread. A proposal is suggested for the optimal optics at the so-called SS30HB interval in the Recycler, where electron cooling is supposed to be applied. Both electron cooling and the phase trombone requirements are taken into account. The electron optic scheme is also presen… more

Clear Sky Identification Using Data From Remote Sensing Systems at ARM's Southern Great Plains Site

Description: Clouds profoundly affect our weather and climate due, in large part, to their interactions with radiation. Unfortunately, our understanding of these interactions is, at best, incomplete, making it difficult to improve the treatment of atmospheric radiation in climate models. The improved treatment of clouds and radiation, and a better understanding of their interaction, in climate models is one of the Department of Energy's Atmospheric Radiation Measurement (ARM) Program's major goals. To learn… more

Electronic Commerce: An Introduction

Description: Electronic commercial transactions over the Internet, or “e-commerce,” have grown so fast over the last five years that many experts continue to underestimate its growth and development. Whether retail business-to-customer or business-to-business transactions, e-commerce shows no signs of slowing down. In turn, policymakers both in the United States and abroad are likely to face increasingly complex issues of security, privacy, taxation, infrastructure development and other issues in 2000 a… more

Entanglement and Quantum Computation: An Overview

Description: This report presents a selective compilation of basic facts from the fields of particle entanglement and quantum information processing prepared for those non-experts in these fields that may have interest in an area of physics showing counterintuitive, ''spooky'' (Einstein's words) behavior. In fact, quantum information processing could, in the near future, provide a new technology to sustain the benefits to the U.S. economy due to advanced computer technology.

AN INNOVATIVE INTEGRATED APPROACH TO MINIMIZING GYPSUM AND PYRITE WASTES BY CONVERSION TO MARKETABLE PRODUCTS

Description: The objective of this research program is to develop a novel integrated process to eliminate millions of tons of gypsum and pyrite wastes generated annually by the U.S. energy industries and reduce the emission of millions of tons of greenhouse gas carbon dioxide. This was accomplished by converting gypsum and pyrite wastes to marketable products such as lime, direct reduced iron (DRI), and sulfur products and obviating the need to calcine millions of tons of limestone for use in utility scrubb… more

Method to Correlate CFD Discriminator Level and Energy Deposition by Neutrons and Photons in a Fast Plastic Scintillating Detector

Description: This paper presents an experimental approach to determine the neutron and gamma ray thresholds in fast, organic scintillating detectors. Neutron threshold energy is determined using a time-of-flight technique, while gamma ray threshold is inferred by locating the Compton edge for various reference gamma sources. These energy thresholds are then related to the Constant Fraction Discriminator (CFD) levels used in these experiments.

First, to specify, order and install a new high current ion source for more rapid and stable proton irradiation. Second, to assess the use of low temperature irradiation and chromium pre-enrichment in an effort to isolate a radiation damage microstructure in stainless steel without the effects of RIS. Third, to initiate irradiation of reactor pressure vessel steel and … more
