Title: Space reactors. Progress report, July-September 1981

Abstract

Progress in technology development for the Space Power Advanced Reactor (SPAR) project is reported for the period July 1-September 30, 1981. The weights of neutron and gamma shields required to protect the SPAR system payloads for a range of permissible exposures have been determined, and initial results are reported. SPAR reactor safety in the case of water immersion has been modeled. Approval-in-Principle has been received for the SPAR fuel test in the Experimental Breeder Reactor-II (EBR-II); the heat pipe developed for this test is performing well. SPAR system design variations are being examined under the possibility of using long core heat pipes. Testing of the initial molybdenum/sodium artery heat pipe continued, with ambiguous results. Fabrication of the first all-bonded thermoelectric units has been completed and testing has been initiated.

  • Flow-Induced Vibration for Light Water Reactors (FIV for LWRs) is a program designed to improve the FIV performance of light water reactors through the development of design criteria, analytical models for predicting behavior of components, and general scaling laws to improve the accuracy of reduced-scale tests, and through the identification of high FIV risk areas. The program is managed by the General Electric Nuclear Power Systems Engineering Department and has three major contributors: General Electric Nuclear Power Systems Engineering Department (NPSED), General Electric Corporate Research and Development (CR and D) and Argonne National Laboratory (ANL). The program commenced December 1,more » 1976. This progress report summarizes the accomplishments achieved during the final period from July 1981 to September 1981. This is the last quarterly progress report to be issued for this program.« less

    This report summarizes the work carried out at the University of Pittsburgh for the multiphase flow process laboratory supported by Gulf Research and Development Company. The work is divided into three parts. In part A, data on gas holdup and axial dispersion of heat for several liquids other than water for a continuous bubble column are described. The report also compares the new data with the past data for air-water system. Part B describes some experimental data for newly erected batch system. The data, once again, are obtained for the liquids other than water. In Part C some data formore » the mass transfer coefficient in an agitated high pressure system are described. These data show the effect of pressure on the mass transfer coefficient. The proposed future work on all three parts of the laboratory is also briefly described in the report.« less

    The goal of this research is to provide a basis for determining the optimum conditions (target species and thickness) for producing D/sup -/ beams by the double capture technique. High production efficiency and low angular divergence are desired. The effort has two components: a modeling effort to determine the D/sup -/ yield and angular scattering as a function of target thickness, and an experimental effort to measure the angular differential cross sections that are required as input data in the model. Initial work in both areas has focussed on the H, D-Cs system, which has appeared to produce the highestmore » D/sup -/ yields.« less

  • The prosecution of the technical aspects of the Statement of Work leading to the engineering design and assessment of a 50,000-bpd coal-to-methanol-to-gasoline plant proceeded at an accelerated pace. The procurement of data for proprietary processes other than the mandated Texaco Coal Gasification Process (TCGP) and Mobil Methanol-to-Gasoline (MTG) Process was advanced by fixing the process design operating conditions of the TCGP, thereby allowing specification of downstream processing unit requirements. Specific licensors and proprietary processes selected for incorporation into the gasoline plant's overall design are Air Liquide, Inc. for air separation technology, Lotepro Corporation for acid gas removal, The Ralph M.more » Parsons Company (Parsons) for Claus sulfur recovery and The Beavon-Stretford Sulfur Recovery Process, and Lurgi Corporation for methanol synthesis. The analysis of alternative processes and preparation of Process Selection Study Reports by Parsons followed by review, comment and/or approval by Grace represents a major portion of the gasoline plant design effort during the reporting period. Following receipt of DOE's concurrence with the Environmental Protection Agency's (EPA) determination that an EIS would be required as a prerequisite to construction and operation of the gasoline plant, dialogues were established among Grace, DOE, EPA and the US Army Corps of Engineers (COE) for the purpose of establishing the LFA and among Grace, EPA and COE to ascertain the requirements of both EPA and COE for the preparation of an EIS. Agreement was reached on COE's serving as the LFA.« less

  • Scale-up correlations have been developed from the data gathered during this quarter. Data from two validated test periods together with three previousl validated runs have yielded equations which allow good correlation (mostly within +- 3% and all with +- 10%) for the following key parameters: (a) coal carbon gasified in stage 2, (b) coal carbon converted to methane in stage 2, (c) coal carbon converted to carbon oxides in stage 2. These have been correlated as a function of temperature, residence time and partial pressure of hydrogen and/or steam. The methane correlation is of the form derived from theory bymore » Zahradnik and co-workers early in the development of the Bi-Gas Process.« less
