Comparison of TRAC and RELAP5 reactor system calculations for a DEGB LOCA in K-14. 1

Description: A comparison of TRAC and RELAP5 predictions of steady-state and DEGB LOCA results (FI phase) for K-14.1 has been made. Both codes had been previously benchmarked against 1985 L Reactor AC Flow data and were under configuration control. The purpose of the code-to-code comparison is to provide insight on the transient uncertainty in TRAC plenum and tank bottom plenum pressures. The comparisons focus on LOCA results between 0.5 and 2.0 s, which is the primary period of interest for Flow Instabilit… more

Genes and gene expression: Localization, damage and control -- A multilevel and inter-disciplinary study

Description: All projects are working toward a goal for describing the three dimensional nuclear topography in terms of relative spatial relationships among genes (specific DNA sequence). Methods are now being perfected to detect these genes, quantitatively and spatially, to perturb these genes specifically, and to measure the perturbation in order to assure specificity. We are developing methods to assay, after perturbation of the target DNA within living cells, whether or not only the target sequence are … more

H-Area Seepage Basins: Groundwater quality assessment report, Savannah River Site

Description: During the second quarter of 1990 the wells which make up the H-Area Seepage Basins (H-HWMF) monitoring network were sampled. Laboratory analyses were performed to measure levels of hazardous constituents, indicator parameters, tritium, nonvolatile beta, and gross alpha. A Gas Chromatograph Mass Spectrometer (GCMS) scan was performed on all wells sampled to determine any hazardous organic constituents present in the groundwater. The primary contaminants observed at wells monitoring the H-Area S… more

Quench propagation in the SSC dipole magnets

Description: The effects of quench propagation are modeled in 40mm and 50mm diameter collider dipole magnet designs. A comparative study of the cold diode (passive) and quench heater (active) protection schemes will be presented. The SSCQ modeling program accurately simulates the axial quench velocity and uses phenomenological time delays for turn-to-turn transverse propagation. The axial quench velocity is field dependent and consequently, each conductor's quench profile is tracked separately. No symmetry … more

Resolutions to difficulties experienced in SSC cable fabrication during the initial scale-up period

Description: Late in 1988, a prototype high speed cable machine was built by industry and delivered in FY88 for the Superconducting Super Collider (SSC), and delivered to New England Electric Wire Corp. for the fabrication of SSC cable. This cabling machine has produced the majority of the cable needed for the SSC Dipole Program. During the past year and a half we have experienced several cabling difficulties that were not seen previously. These difficulties were due to new techniques and equipment relating… more

Simulation of a Standing-Wave Free-Electron Laser

Description: The standing-wave free-electron laser (FEL) differs from a conventional linear-wiggler microwave FEL in using irises along the wiggler to form a series of standing-wave cavities and in reaccelerating the beam between cavities to maintain the average energy. The device has been proposed for use in a two-beam accelerator (TBA) because microwave power can be extracted more effectively than from a traveling-wave FEL. The standing-wave FEL is modeled in the continuum limit by a set of equations desc… more

The influence of interfacial properties on two-phase liquid flow of organic contaminants in groundwater

Description: The purpose of this project is to investigate how changes in interfacial chemical properties affect two-phase transport relationships. Specifically, the objective is to develop a quantitative theory that will enable the prediction of changes in the capillary pressure-saturation relationship, a fundamental constitutive relationship in multiphase flow modeling, from changes in interfacial properties through a knowledge of their effect on wettability. The information presented here summarizes the … more

Texture analysis of bulk YBa sub 2 Cu sub 3 O sub x by neutron diffraction

Description: Neutron diffraction has been used to generate Orientation Distribution Functions for two sinter-forged YBa{sub 2}Cu{sub 3}O{sub x} specimens. Sinter forging imparted a strong texture, with c axes of crystals preferentially aligned parallel to the forging direction. The distribution of a and b axes was not uniform, which may have implications to critical current density. 14 refs., 6 figs.
