The Hydrogen Content of Fabricated Uranium

Description: The hydrogen contents of several types of fabricated uranium have been determined by a vacuum method and expressed in terms of ccH2/ccU. The data indicate that alpha-rolled metal contains about 0.25 ccH2(STP)/ccU whereas beta heat-treated uranium yielded values between 0.30 and 0.37 cc per cc. Restricted efforts were made to determine where in the heat treatment the 5 to 10 cc of hydrogen per slug were taken up. It appears that no one operation is wholly responsible for this additional gas, although reactions between beta heat treated surfaces containing microscopic defects, and nitric acid may possibly play a large role. In general it may be said that slug produced by powder metallurgical techniques contain less hydrogen than pieces produced by rolling and heat treatment.

SM-1 Research and Development Program: Long-lived Induced Activity Buildup During SM-1 Core I Lifetime. Task XVIII, Phase I

Description: Abstract: The results of activity buildup studies in the SM-1 performed during Core I lifetime (June 3, 1957 to April 28, 1960) are reported. Data are presented on the extent, nature, and mechanism of the buildup of long-lived gamma emitting nuclides in the reactor primary system. Radiation levels after reactor shutdown are presented, as well as mathematical equations used to account for the observed activity levels. The data have shown that Co60 is the major contributor to radiation levels in the SM-1. Co60 activity arises from the cobalt in Haynes 25 alloy flux suppressors, and the cobalt impurity in stainless steel. After 35 months operation at an average power level of 55%, deposited Co60 activity accounted for approximately 83% of the total radiation level (mr/hr) contributed by the long-lived gamma emitting nuclides. The contribution of the primary coolant activity to the total radiation level is insignificant when compared to the contribution of the activity deposited on the walls of the system. The radiation level on the super-heater side of the steam generator was about 1400 mr/hr after 35 months of reactor operation. The percentages of Co60 activity in the coolant and in the deposits were not the same. This indicates either that nuclides are depositing irreversibly on the surface of the system, or that all nuclides are not exchanging at the same rate. The ratio of Co58/Co60 in the deposits shows that a major fraction of the nuclides are irreversibly deposited. Mathematical equations derived during the course of work were used to predict the observed activity buildup on SM-1 primary system surfaces. Certain constants in the the equations were obtained from the experimental data. Calculated values of activity levels based on the equations were in good agreement with the activity levels found on the primary system. The equations may be …

SM-2 Critical Experiments : CE-1

Description: Abstract: Critical experiment studies were performed, varying the parameters U235, B10 and metal to water ratio, in the SM-2 7 x 7 core configuration with 38 stationary elements and seven control rods of the SM-1 (APPR-1) type. An experimental mock-up of the SM-1 was assembled using the basic SM-2 fuel plates. Excellent agreement between the SM-1 boron loading, determined by chemical analysis, and the SM-1 mock-up boron loading, for equivalent bank positions, was noted. Several SM-2 mock-ups, cold clean and midlife, were assembled and studied with regard to reflector effects, flow divider effects, relative control rod array worths, critical rod configurations, and relative power distributions. The results of these experiments indicate as satisfactory a U235 loading of 36.4 Kg and a B10 loading of 63.4 grams for the SM-2. Attention is drawn to numerous power peaks present in the active core. The open seven control rod array has a slight reactivity advantage over the closed seven array and consequent minor disadvantage with respect to "stuck rod" criteria.

Comparison of AMOS computer code wakefield real part impedances with analytic results

Description: We have performed eleven AMOS (Azimuthal Mode Simulator)[1] code runs with a simple, right circular cylindrical accelerating cavity inserted into a circular, cylindrical, lossless beam pipe to calculate the real part of the n = 1(dipole) transverse wakefield impedance of this structure. We have compared this wakefield impedance in units of ohms/m(Wm) over the frequency range of 0-1 GHz to analytic predictions from Equation (2.3.8) of Briggs et al[2]. The results from Equation (2.3.8) were converted from the CGS units of statohms to the MKS units of ohms({Omega}) and then multiplied by (2{pi}f)/c = {Omega}/c = 2{pi}/{lambda}, where f is the frequency in Hz, c is the speed of light in vacuum in m/sec, {omega} is the angular frequency in radians/sec, and {lambda} is the wavelength in m. The dipole transverse wakefield impedance written to file from AMOS must be multiplied by c/o to convert it from units of {Omega}/m to units of {Omega}. The agreement between the AMOS runs and the analytic predictions are excellent for computational grids with square cells (dz = dr) and good for grids with rectangular cells (dz < dr). The quantity dz is the fixed-size axial grid spacing, and dr is the fixed-size radial grid spacing. We have also performed one AMOS run for the same geometry to calculate the real part of the n = 0(monopole) longitudinal wakefield impedance of this structure. We have compared this wakefield impedance in units of {Omega} with analytic predictions from Equation (1.4.8) of Briggs et al[1] converted to the MKS units of {Omega}. The agreement between the two results is excellent in this case. For the monopole longitudinal wakefield impedance written to file from AMOS, nothing must be done to convert the results to units of {Omega}. In each case, the computer calculations were carried out to …

FY04-Q4 REPORT: LX-17 MODELING

Description: TATB containing explosives tend to permanently expand as their temperatures are increased or thermally cycled, a phenomenon known as ''ratchet-growth.'' Mesoscale simulations using dissipative particle dynamics (DPD) have been carried out in order to study the geometric packing effects of TATB pressed powders under stress conditions. Further, our mesoscale simulations of polycrystalline TATB pressed powders have been used to predict hot-spot changes as a function of temperature (thermal cycling) and confinement. Our DPD simulations showed irreversible permanent growth in the mesoscale pressed powders only when crystal fracture induced by the anisotropic thermal expansion of TATB was incorporated into the model.

Preliminary hazard analysis for the Brayton Isotope Ground Demonstration System (including vacuum test chamber)

Description: The Preliminary Hazard Analysis (PHA) of the BIPS-GDS is a tabular summary of hazards and undesired events which may lead to system damage or failure and/or hazard to personnel. The PHA reviews the GDS as it is envisioned to operate in the Vacuum Test Chamber (VTC) of the GDS Test Facility. The VTC and other equipment which will comprise the test facility are presently in an early stage of preliminary design and will undoubtedly undergo numerous changes before the design is frozen. The PHA and the FMECA to follow are intended to aid the design effort by identifying areas of concern which are critical to the safety and reliability of the BIPS-GDS and test facility.

Exposure Based Health Issues Project Report: Phase I of High Level Tank Operations, Retrieval, Pretreatment, and Vitrification Exposure Based Health Issues Analysis

Description: The Department of Energy (DOE) has the responsibility to understand the ''big picture'' of worker health and safety which includes fully recognizing the vulnerabilities and associated programs necessary to protect workers at the various DOE sites across the complex. Exposure analysis and medical surveillance are key aspects for understanding this big picture, as is understanding current health and safety practices and how they may need to change to relate to future health and safety management needs. The exposure-based health issues project was initiated to assemble the components necessary to understand potential exposure situations and their medical surveillance and clinical aspects. Phase I focused only on current Hanford tank farm operations and serves as a starting point for the overall project. It is also anticipated that once the pilot is fully developed for Hanford HLW (i.e., current operations, retrieval, pretreatment, vitrification, and disposal), the process and analysis methods developed will be available and applicable for other DOE operations and sites. The purpose of this Phase I project report is to present the health impact information collected regarding ongoing tank waste maintenance operations, show the various aspects of health and safety involved in protecting workers, introduce the reader to the kinds of information that will need to be analyzed in order to effectively manage worker safety.

PHENIX EXPERIMENT AT RHIC: DECADAL PLAN 2004-2013

Description: The PHENIX Collaboration has developed a plan for the detailed investigation of quantum chromodynamics in the next decade. The demonstrated capabilities of the PHENIX experiment to measure rare processes in hadronic, leptonic and photonic channels, in combination with RHIC's unparalleled flexibility as a hadronic collider, provides a physics program of extraordinary breadth and depth. A superlative set of measurements to elucidate the states of both hot and cold nuclear matter, and to measure the spin structure of the proton has been identified. The components of this plan include: (1) Definitive measurements that will establish the nature of the matter created in nucleus+nucleus collisions, that will determine if the description of such matter as a quark-gluon plasma is appropriate, and that will quantify both the equilibrium and non-equilibrium features of the produced medium. (2) Precision measurements of the gluon structure of the proton, and of the spin structure of the gluon and sea-quark distributions of the proton via polarized proton+proton collisions. (3) Determination of the gluon distribution in cold nuclear matter using proton+nucleus collisions. Each of these fundamental fields of investigation will be addressed through a program of correlated measurements in some or all of the following channels: (1) Particle production at high transverse momentum, studied via single particle inclusive measurements of identified charged and neutral hadrons, multi-particle correlations and jet production. (2) Direct photon, photon+jet and virtual photon production. (3) Light and heavy vector mesons. (4) Heavy flavor production. These measurements, together with the established PHENIX abilities to identify hadrons at low transverse momentum, to perform detailed centrality selections, and to monitor polarization and luminosity with high precision create a superb opportunity for performing world-class science with PHENIX for the next decade. A portion of this program is achievable using the present capabilities of PHENIX experimental apparatus, but the physics …
