Reactor FaceMap Tool: A modern graphics tool for displaying reactor data

Description: A prominent graphical user interface in reactor physics applications at the Savannah River Site is the reactor facemap display. This is a two dimensional view of a cross section of a reactor. In the past each application which needed a facemap implemented its own version. Thus, none of the code was reused, the facemap implementation was hardware dependent and the user interface was different for each facemap. The Reactor FaceMap Tool was built to solve these problems. Through the use of modern … more

Microstructural Analyses of Topopah Spring Tuff from the Large Block Test at Fran Ridge, Nevada

Description: Microstructural information (e.g., porosity, pore size distribution, and surface area) of porous media is critical to understanding water transport mechanisms and physical properties and their bearing on geophysical measurements. We report microstructural data obtained by mercury injection porosimetry (MIP) on 33 samples of densely welded Topopah Spring tuff from Fran Ridge, Yucca Mountain, Nevada Test Site (NTS), Nevada. The characterization of these samples is also important for the interpret… more

Evidence for dibaryon resonances in nucleon-nucleon scattering

Description: There has been a revival of interest in the subject of nucleon-nucleon resonances in the past 3 to 4 years, largely generated by experimental results from the polarized beam program at the Argonne ZGS. Evidence from experimental results and phase shift and phenomenological analyses incorporating these results regarding the existence of these resonances is summarized. 20 figures.

New National Wind Potential Estimates for Modern and Near-Future Turbine Technologies

Description: Recent advancements in utility-scale wind turbine technology and pricing have vastly increased the potential land area where turbines can be deployed in the United States. This presentation quantifies the new developable land potential (e.g., capacity curves), visually identifies new areas for possible development (e.g., new wind resource maps), and begins to address deployment barriers to wind in new areas for modern and future turbine technology.

Dimensional Stability of Heavy Walled Incoloy 800 Cladding Tubes, Data

Description: The effects of SCB coating, thermal shock and hermal scak on the dimensional stability of four heavy walled Incolcy 800 cladding tubes, ranging in thickness from 20 to 44 mils, was investigated. The results of the study were summarized in TI-759-240-029. This report serves as a repository for the detailed data and profilometer traces used in the preparation of that summary.

Surface structure determinations of crystalline ionic thin films grown on transition metal single crystal surfaces by low energy electron diffraction

Description: The surface structures of NaCl(100), LiF(100) and alpha-MgCl2(0001) adsorbed on various metal single crystals have been determined by low energy electron diffraction (LEED). Thin films of these salts were grown on metal substrates by exposing the heated metal surface to a molecular flux of salt emitted from a Knudsen cell. This method of investigating thin films of insulators (ionic salts) on a conducting substrate (metal) circumvents surface charging problems that plagued bulk studies, thereby… more

Electromagnetic Imaging of CO2 Sequestration at an Enhanced Oil Recovery Site

Description: Lawrence Livermore National Laboratory (LLNL) is currently involved in a long term study using time-lapse multiple frequency electromagnetic (EM) characterization at a waterflood enhanced oil recovery (EOR) site in California operated by Chevron Heavy Oil Division in Lost Hills, California (Figure 1). The petroleum industry's interest and the successful imaging results from this project suggest that this technique be extended to monitor CO{sub 2} sequestration at an EOR site also operated by Ch… more

Reservoir Characterization: Electromagnetic Imaging of CO2 for EOR Processes

Description: Lawrence Livermore National Laboratory is currently involved in a long term study using time-lapse multiple frequency electromagnetic (EM) imaging at a carbon dioxide (CO{sub 2}) enhanced oil recovery (EOR) site in the San Joaquin Valley, California. The impetus for this proposed research project is to develop the ability to image subsurface CO{sub 2} during EOR processes while simultaneously discriminating between background heavy petroleum and water deposits. Using field equipment developed a… more

Electromagnetic Imaging of CO2 Sequestration at an Enhanced-Oil-Recovery Site

Description: The two year LDRD-ER-089 project Electromagnetic Imaging of CO{sub 2} Sequestration at an Enhanced-Oil-Recovery Site used a dual track approach to imaging and interpreting the effectiveness and migration of CO2 injection at an enhanced oil recovery site. Both field data and laboratory data were used together to aid in the interpretation and understanding of CO{sub 2} flow in a heavily fracture enhanced oil recovery site. In particular, project highlights include; {lg_bullet} The development of … more

Interpretation Of Multifrequency Crosswell Electromagnetic Data With Frequency Dependent Core Data

Description: Interpretation of cross-borehole electromagnetic (EM) images acquired at enhanced oil recovery (EOR) sites has proven to be difficult due to the typically complex subsurface geology. Significant problems in image interpretation include correlation of specific electrical conductivity values with oil saturations, the time-dependent electrical variation of the subsurface during EOR, and the non-unique electrical conductivity relationship with subsurface conditions. In this study we perform laborat… more

Electrical properties of Topopah Spring tuff as a function of saturation

Description: Much attention has been focused on the hydrologic properties of tuff from the potential nuclear waste repository at Yucca Mountain, Nevada. The successful characterization of the near-field environment of the potential repository depends on the ability to understand and predict the movement of water within the matrix and fractures when the rock mass is heated by nuclear waste. This understanding will come only after many combined laboratory experiments, field tests, and model calculations have … more
