Burner Stabilized Flames in Fluids

Description: In this report it is shown that a burner placed in a combustible fluid can have a stabilizing effect on a plane flame. A mathematical model is derived in which the flame is modeled as a surface of discontinuity in the flow field. Jump conditions for the fluid variables, as well as an expression for the flame speed, are obtained from an asymptotic analysis of the detailed structure of the flame. The model is applied to investigate the linear stability of a plane flame. Stable behavior is shown t… more

Corrosion Behavior of Several Metals in Ethylene Glycol-Base Heat-Transfer Fluids under Conditions Encountered in Solar Energy Systems

Description: The corrosion behavior of aluminum, copper, and iron in inhibited ethylene glycol-ASTM corrosive water solutions was evaluated in a laboratory loop under isothermal and heat-flux conditions for 1000 h at temperatures between 378 and 413 degrees K, in static autoclave tests at 450 degrees K for 500 h, and by potentiodynamic polarization measurements at temperatures between 298 and 348 degrees K. The effect of time, temperature, and ethylene glycol concentration of the heat-transfer fluid on the … more

Experiments on Cold-Trap Regeneration by NaH Decomposition

Description: Cold-trap regeneration may be very important in future LMFBRs because of the expected high hydrogen source from the steam generators. This hydrogen precipitates as NaH in the cold trap and may fill the trap within one year of operation. Several methods of cold-trap regeneration were considered, but the simplest and least expensive appears to be decomposition of NaH under vacuum at elevated temperatures. Experiments were done to assess the feasibility of this method for cold-trap regeneration. S… more

Branching Fraction in the Radioactive Decay of ⁸⁵mKr

Description: The branching fraction in the decay of the fission product ⁸⁵m-krypton⁸⁵m to the ground state ⁸⁵krypton (10.75 y) was measured relative to the total decay to both ⁸⁵krypton and ⁸⁵Rb. Samples of uranium-235 were highly irradiated in a high-flux reactor and dissolved. ⁸⁵Rb was measured by isotope-dilution mass spectrometry, and the ⁸⁵krypton was counted in GM tubes the counting efficiencies of which were calibrated with a standardized ⁸⁵krypton gas of known disintegration rate. The branching frac… more

Corrosion and Mechanical Behavior of Materials for Coal Gasification Applications

Description: A state-of-the-art review is presented on the corrosion and mechanical behavior of materials at elevated temperatures in coal-gasification environments. The gas atmosphere in coal-conversion processes are, in general, complex mixtures which contain sulfur-bearing components (hydrogen sulfide, SO2, and COS) as well as oxidants (carbon dioxide/carbon monoxide and water/hydrogen). The information developed over the last five years clearly shows sulfidation to be the major mode of material degradat… more

SACO-1: a Fast-Running LMFBR Accident-Analysis Code

Description: SACO is a fast-running computer code that simulates hypothetical accidents in liquid-metal fast breeder reactors to the point of permanent subcriticality or to the initiation of a prompt-critical excursion. In the tradition of the SAS codes each sub-assembly is modeled by a representative fuel pin with three distinct axial regions to simulate the blanket and core regions. However, analytic and integral models are used wherever possible to cut down the computing time and storage requirements. Th… more

COMMIX-SA-1: a Three-Dimensional Thermohydrodynamic Computer Program for Solar Applications

Description: COMMIX-SA-1 is a three-dimensional, transient, single-phase, compressible-flow, component computer program for thermohydrodynamic analysis. It was developed for solar applications in general, and for analysis of thermocline storage tanks in particular. The conservation equations (in cylindrical coordinates) for mass, momentum, and energy are solved as an initial-boundary-value problem. The detailed numerical-solution procedure based on a modified ICE (Implicit Continuous-Fluid Eulerian) techniq… more

The Delayed-Neutron Fraction in a Pulsed Spallation Neutron Source

Description: The fraction of delayed neutrons beta in slow-neutron beams from a uranium-238 pulsed spallation neutron source is 0.0053 for 300 MeV protons. This measurement appears to be the first one of this quantity. The result indicates that, for most classes of measurements, the delayed-neutron background in time-of-flight instruments will be unimportant, and places constraints on the physics description of spallation targets. The measurement was performed at the prototype pulsed spallation neutron sour… more

Fast Critical Assembly Safeguards: NDA Methods for Highly Enriched Uranium. Summary Report, October 1978 - September 1979, Volume 3

Description: Nondestructive assay (NDA) methods, principally passive gamma measurements and active neutron interrogation, have been studied for their safeguards effectiveness and programmatic impact as tools for making inventories of highly enriched uranium fast critical assembly fuel plates. It was concluded that no NDA method is the sole answer to the safeguards problem, that each of those emphasized here has its place in an integrated safeguards system, and that each has minimum facility impact.

Conceptual Design of Electrical Balance of Plant for Advanced Battery Energy Storage Facility. Annual Report March 1979

Description: Large-scale efforts are in progress to develop advanced batteries for utility energy storage systems. Realization of the full benefits available from those systems requires development, not only of the batteries themselves, but also the ac/dc power converter, the bulk power interconnecting equipment, and the peripheral electric balance of plant equipment that integrate the battery/converter into a properly controlled and protected energy system. This study addresses these overall system aspects… more

Stability of Tube Rows in Crossflow

Description: A mathematical model for the instability of tube rows subjected to crossflow is examined. The theoretical model, based on the fluid-force data for a pitch-to-diameter ratio of 1.33, provides additional insight into the instability phenomenon. Tests are also conducted for three sets of tube rows. The effects of mass ratio, tube pitch, damping, detuning and finned tubes are investigated. Theoretical results and experimental data are in good agreement.

Fuel-Motion Diagnostics and Cineradiography

Description: Nuclear and non-nuclear applications of cineradiography are reviewed, with emphasis on diagnostic instrumentation for in-pile transient-reactor safety testing of nuclear fuel motion. The primary instrument for this purpose has been the fast-neutron hodoscope, which has achieved quantitative monitoring of time, location, mass, and velocity of fuel movement under the difficult conditions associated with transient-reactor experiments. Alternative diagnostic devices that have been developed have no… more

Randomly Generated Test Problems for Positive Definite Quadratic Programming

Description: A procedure is described for randomly generating positive definite quadratic programming test problems. The test problems are constructed in the form of linear least squares problems subject to linear constraints. The probability measure for the problems so generated is invariant under orthogonal transformations. The procedure allows the user to specify the size of the least squares problem (number of unknown parameters, number of observations, and number of constraints); the relative magnitude… more

An LMA-Based Theorem Prover

Description: We describe here a theorem prover constructed from the facilities provided by Logic Machine Architecture (LMA). This program is not part of LMA itself, but illustrates the level of inference-based system which can be constructed from the LMA package of tools. It is a clause-based theorem prover supporting a wide variety of techniques which have proven valuable over the years in a long-running automated deduction research project. In addition, it is designed to present a convenient, interactive … more
