Design-Development and Operation of the Experimental Boiling-Water Reactor (EBWR) Facility, 1955--1967

Description: The Experimental Boiling-Water Reactor (EBWR) was designed, built, and operated to provide experience and engineering data that would demonstrate the feasibility of the direct-cycle, boiling-water reactor and be applicable to improved, larger nuclear power stations; and was based on information obtained in the first test boiling-water reactors, the BORAX series. EBWR initially produced 20 MW(t), 5 MW(e); later modified and upgraded, as described and illustrated, it was operated at up to 100 MW(… more

A Portable Generic Elementary Function Package in Ada and an Accurate Test Suite

Description: A comprehensive set of elementary functions has been implemented portably in Ada. The high accuracy of the implementation has been confirmed by rigorous analysis. Moreover, we present new test methods that are efficient and offer a high resolution of 0.005 unit in the last place. These test methods have been implemented portably here and confirm the accuracy of our implemented functions. Reports on the accuracy of other function libraries obtained by our test programs are also presented.

Two-Phase Flow Patterns and Frictional Pressure Gradients in a Small Rectangular Channel : a Comparison Between Two Horizontal Orientations

Description: In horizontal flow through a rectangular channel, the channel cross section can be oriented so that the long side is either vertical or horizontal. The effect of cross-section orientation on the fluid dynamic characteristics of two-phase flow is of interest in plate-fin heat exchanger design because a heat exchanger can be similarly oriented to operate in either of the two orientations. An earlier study of two-phase flow patterns and frictional pressure gradients in a small rectangular channel … more

Stress Corrosion Cracking of Candidate Waste Container Materials

Description: Six alloys have been selected as candidate container materials for the storage of high-level nuclear waste at the proposed Yucca Mountain site in Nevada. These materials are Type 304L stainless steel (SS), Type 316L SS, Incoloy 825, P-deoxidized Cu, Cu-30%Ni, and Cu-7%A1. The present program has been initiated to determine whether any of these materials can survive for 300 years in the site environment without developing through-wall stress corrosion cracks, and to assess the relative resistanc… more

An evaluation of the Nb-93(n,n prime )Nb-93m dosimeter reaction for ENDF/B-VI

Description: The Nb-93(n,n{prime})Nb-93m reaction plays an important role in nuclear energy applications. Because of its low threshold energy and relatively long half-life, it is a desirable reaction for long-term neutron fluence dosimetry in nuclear fission reactors. An evaluation of the differential cross section for this reaction was completed in 1985 by this laboratory as part of a comprehensive effort involving all neutron cross sections for niobium. The objective was to provide input for ENDF/B-VI. It… more

Proof-of-Concept Oil Shale Facility Environmental Analysis Program

Description: The objectives of the Project are to demonstrate: (1) the Modified In- Situ (MIS) shale oil extraction process and (2) the application of CFBC technology using oil shale, coal and waste gas streams as fuels. The project will focus on evaluating and improving the efficiency and environmental performance of these technologies. The project will be modest by commercial standards. A 17-retort MIS system is planned in which two retorts will be processed simultaneously. Production of 1206-barrels per … more

Vibration study of the APS magnet support assemblies

Description: Stability of the positron closed orbit is a requirement for successful operation of the Advanced Photon Source. The fact that vibration of the storage ring quadrupole magnets can lead to distortion of the positron closed orbit and to potentially unacceptable beam emittance growth provides the motivation for the subject studies. Low frequency vibrations can be controlled with steering magnets using feedback systems, provided the vibration amplitudes are within the dynamic range of the controller… more

Compilation of Failure Data and Fault Tree Analysis for Geothermal Energy Conversion Systems

Description: The failure data for geothermal energy conversion facilities collected to date are compiled and tabled. These facilities have not accumulated sufficient production history to reliably estimated component failure rates. In addition, the improvements made in drilling technology in recent years may have made less pertinent the accumulation of data on well failures.

Summary of 1988 WIPP (Waste Isolation Pilot Plant) Facility horizon gas flow measurements

Description: Numerous gas flow measurements have been made at the Waste Isolation Pilot Plant (WIPP) Facility horizon during 1988. All tests have been pressure decay or constant pressure tests from single boreholes drilled from the underground excavations. The test fluid has been nitrogen. The data have been interpreted as permeabilities and porosities by means of a transient numerical solution method. A closed-form steady-state approximation provides a reasonable order-of-magnitude permeability estimate. T… more

Numerical modeling of HF skywave radiation from antennas in irregular terrain

Description: The problem of computing the radiation pattern of an HF antenna sited in irregular terrain was investigated. The primary interest is in antennas for skywave communication, however ionospheric models were not considered. Several methods for modeling terrain effects are briefly reviewed. A geometrical optics model for arbitrary terrain is developed and results are compared with published results from solution of a Volterra integral equation for scattering by a Gaussian ridge.

Determination of the effect of various hydrogen bonding functionalities on the viscosity of coal liquids

Description: The objective of this program was to differentiate and quantitate the effects of various hydrogen bonding functionalities on the viscosity of coal liquids. Emphasis was on separating and measuring the individual effect of phenolic (acidic) and aromatic amino (basic) hydrogen bonding functionalities on the viscosity of coal liquids. The elimination of both acidic and basic hydrogen bondings was attempted by using trifluoroacetyl chloride and butyric acid in derivatization; and the elimination of… more

Intramolecular energy transfer reactions in polymetallic

Description: This report is concerned with intramolecular, energy-transfer reactions. The concept of preparing synthetically a complex molecular species, capable of absorbing a photon at one metal center (antenna fragment), transferring that energy to a second metal center (reactive fragment) via a bridging ligand was first reported by our group in 1979. It is now apparent that a major emphasis in inorganic chemistry in the future will involve these types of molecular ensembles. Complexes discussed include … more
