A Unified and Mechanistic Approach to Creep-Fatigue Damage

Description: A new creep-fatigue equation is proposed that takes into account both plastic strain and strain rate. The coefficients and exponents in the damage-rate equation are interpreted by means of the various damage mechanisms of the material. The damage-rate equation has been integrated to analyze various phenomena such as the effects of plastic strain rate on monotonic tensile or creep rupture time, rising mean strain on the low-cycle fatigue behavior at elevated temperature, tensile and compressive … more

Leakage Flow-Induced Vibrations for Variations of a Tube-in-Tube Slip Joint

Description: Variations in the design of a specific slip joint separating two cantilevered, telescoping tubes conveying water were studied to determine their effect upon the leakage flow-induced vibration self-excitation mechanism known to exist for the original slip joint geometry. The important parameters controlling the self-excitation mechanism were identified, which, along with previous results, allowed the determination of a comprehensive set of design rules to avoid unstable vibrations. This was poss… more

Thermodynamic Analysis of Multicomponent Working Fluids for Rankine Bottoming Cycle Applications

Description: The basic equations underlying a computer code are developed to describe the thermodynamic behavior of multi-component working fluids in Rankine cycles. The code is to be employed in the performance analysis of Rankine bottoming cycle systems. The performance of such systems depends strongly on the working fluid characteristics. The introduction of multi-component mixtures makes available a broad spectrum of fluid properties achievable by varying the mixture composition. The code provides a too… 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

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

Proceedings of the Sixth Meeting of the International Collaboration on Advanced Neutron Sources

Description: Representatives of the Laboratories of the International Collaboration on Advanced Neutron Sources gathered between 28 June and 2 July, 1982 at Argonne National Laboratory for their sixth meeting, ICANS-VI. The meeting was the first opportunity for participants to see Argonne's Intense Pulsed Neutron Source, which went into full operation in August, 1981, and in an important sense celebrated the coming-on-line of this most recent entry into the world's complement of the new generation of neutro… more

Environmental Surveillance of the Palos Park Forest Preserve

Description: This is the second report describing an ongoing environmental surveillance program conducted at the Palos Park Forest Preserve near Chicago, Illinois. The Preserve was a site of a nuclear research laboratory (Site A) from 1943 to 1956 and a radioactive waste burial site (Plot M) from 1944 to 1949. An extensive radiological characterization of the site was conducted from February 1976 to August 1977, and tritium in the form of water was found to be the only radionuclide that migrated from the nu… more

Shellside Waterflow Pressure Drop and Distribution in Industrial-Size Test Heat Exchanger

Description: The shellside pressure drop between the inlet and outlet nozzles as well as the pressure drops through individual sections of different shell-and-tube test-exchanger configurations are measured under water flow. The segmentally baffled test exchanger is nominally 0.6 m (2 ft) in diameter, 3.7 m (12 ft) long and contains a tube bundle of 19 mm (0.75 in.) outside-diameter tubes. Results are reported of 24 test cases obtained from various combinations of parameters: 30 degrees triangular or 90 deg… more

Separation of Rubidium from Irradiated Aluminum-Encapsulated Uranium

Description: A procedure was developed for separating rubidium from irradiated aluminum encapsulated uranium. The separations procedure produces a final ultra-high purity rubidium chloride product for subsequent high performance mass spectrometric analysis. The procedure involves first removing most of the macro-components and fission products by strong base anion exchange using, first, concentrated HCl, then oxalic acid media and second, selectively separating rubidium from alkaline-earth ions and other al… more

Improving the Accuracy of Computed Singular Values

Description: This paper describes a computational method for improving the accuracy of a given singular value and its associated left and right singular vectors. The method is analogous to iterative improvement for the solution of linear systems. That is, by means of a low-precision computation, an iterative algorithm is applied to increase the accuracy of the singular value and vectors; extended precision computations are used in the residual calculation. The method is related to Newton's Method applied to… more

Plan for the Future of Neutron Research on Condensed Matter : An Argonne National Laboratory Report Prepared in Response to the "Report of the Review Panel on Neutron Scattering"

Description: The Review Panel on Neutron Scattering has recommended an expanded budget to allow systematic development of the field. An alternative plan for the future of neutron research on condensed matter is presented here, in case it is not possible to fund the expanded budget. This plan leads, in a rational and logical way, to a world-class neutron source that will ensure the vitality of the field and exploit the many benefits that state-of-the-art neutron facilities can bring to programs in the materi… more

Electron Scattering : Lectures Given at Argonne National Laboratory

Description: This report is an almost verbatim copy of lectures on Electron Scattering given at Argonne National Laboratory in the Fall of 1982 by John Dirk Walecka. Professor Walecka was an Argonne Fellow in the Physics Division from October 1982 to January 1983. The original intent was to type the lecture notes. However, to finish the report in a reasonable time it was necessary to transcribe most of the equations by hand which led to certain notational difficulties. With a single exception in lecture no.… more

Test Results for 36-V Li/FeS Battery

Description: This report describes a collaborative effort between Argonne National Laboratory (ANL) and the Westinghouse Naval Systems Division from 1986 to 1989. This effort resulted in the design, fabrication, and testing of two 36-V lithium-alloy/iron monosulfide (Li/FeS) batteries. The test results provided validation of a conceptual design for a full-scale electric van battery, as well as design and performance data for 12-V Li/FeS modules and fractional-scale battery components.
