Scientific Workstation Evaluation Project: Multidisciplinary Experience with a Scientific Workstation

Description: This document is a formal report on the scientific workstation evaluation project. The objective of this project has been to evaluate a scientific workstation. When new computing systems appeared that exhibited the capabilities necessary to do scientific computing work at relatively low equipment cost, both the staff of the Argonne scientific divisions and we (the Computing Services staff) wished to know more about the equipment and the vendor claims.

Flow-Induced Vibration of the SSME Lox Posts : Additional Issues

Description: A mathematical model is presented for flow-induced vibration of the Space Shuttle Main Engine (SSME) liquid oxygen (LOX) posts. The definition of the critical flow velocity is addressed, and detuning of the vibrations of the LOX posts is discussed. Nonuniform flow distributions in the axial and transverse directions are examined briefly, followed by upstream turbulence. The dependence of response upon post location is addressed briefly. Scruton's number, a mass-damping parameter, is defined and… more

Comparison of the CRAY X-MP-4, Fujitsu VP-200, and Hitachi S-810/20 : an Argonne Perspective

Description: A set of programs, gathered from major Argonne computer users, was run on the current generation of supercomputers: the CRAY X-MP-4, Fujitsu VP-200, and Hitachi S-810/20. The results show that a single processor of a CRAY X-MP-4 is a consistently strong performer over a wide range of problems. The Fujitsu and Hitachi excel on highly vectorized programs and offer an attractive opportunity to sites with IBM-compatible computers.

Germanium-Lithium Argon Scanning System (GLASS) : Design and Experience Through 1974

Description: The germanium-lithium argon scanning system (GLASS) was installed in EBR-II to monitor and analyze the gamma activity of the reactor cover gas and the reactor building air. GLASS has the capability to identify and measure 20 or more gamma peaks. Applied to the reactor cover gas, this capability has proven useful in identifying the source of fission-gas leakage from fuel elements. The gamma-peak data can clearly distinguish a carbide-fuel source from an oxide-fuel source and can often help disti… more

A Summary on Experimental Methods for Statistical Transient Analysis of Two-Phase Gas-Liquid Flow

Description: Much work has been done in the study of two-phase gas-liquid flows. Although it has been recognized superficially that such flows are not homogeneous in general, little attention has been paid to the inherent discreteness of the two-phase systems. Only relatively recently have fluctuating characteristics of two-phase flows been studied in detail. As a result, new experimental devices and techniques have been developed for use in measuring quantities previously ignored. This report reviews and s… more

Considerations Affecting Deep-Well Disposal of Tritium-Bearing Low-Level Aqueous Waste from Nuclear Fuel Reprocessing Plants

Description: Present concepts of disposal of low-level aqueous wastes (LLAW) that contain much of the fission-product tritium from light water reactors involve dispersal to the atmosphere or to surface streams at fuel reprocessing plants. These concepts have been challenged in recent years. Deep-well injection of low-level aqueous wastes, an alternative to biospheric dispersal, is the subject of this presentation. Many factors must be considered in assessing its feasibility, including technology, costs, env… more

Design and Fabrication of the EBR-II Environmental Instrumented Subassembly : Test XX07

Description: The EBR-II environmental instrumented subassembly (EISA), or Test XX07, was designed, fabricated, and irradiated to provide in-core measurements of irradiation conditions. This subassembly contained 57 elements with uranium metal-5 wt.% fissium fuel and four non-fueled elements. It was instrumented with two permanent-magnet flowmeters, 13 coolant thermocouples at various axial and radial locations, 10fuel-centerline thermocouples, and two self-powered detectors. The subassembly was irradiated i… more

Fuel Dynamics Loss-of-Flow Test L3 : Final Report

Description: The behavior of FTR-type, mixed-oxide, pre-irradiated, ''intermediate-power-structure'' fuel during a simulation of an FTR loss-of-flow accident was studied in the Mark-IIA integral TREAT loop. Analysis of the data reported here leads to a postulated scenario (sequence and timing) of events in the test. This scenario is presented, together with the calculated timing of events obtained by use of the SAS code.

Theory of Ionization by Electron Collisions

Description: The problem of calculating comprehensive sets of cross sections for ionization of atoms and molecules is reviewed. Emphasis is put on targets that are already ionized and lower-energy collisions for which the incident electron must be treated on a par with target electrons. The physical circumstances are discussed in which perturbation methods should be adequate, and special investigations are recommended to identify the relevant ranges of parameters more precisely and dependably. A new R-matri… more
