500-MeV electron beam bench-mark experiments and calculations
Experiments measuring the energy deposited by electron beams were performed to provide bench marks against which to evaluate our HANDYL76 electron beam computer code. The experiments, done at Stanford's Mk III accelerator, measured dose vs depth and dose vs radius profiles induced in layered aluminum targets by 500-MeV electrons. The dose was measured by passive thermoluminescence and photographic film placed between aluminum plates. The calculations predict a dose vs radius profile that forward-peaks on axis after the beam passes through a 200-cm air gap; the experimental measurements do not show this peak. This discrepancy indicates there may be a problem in using HANDYL76 to calculate deep penetration of a target with a large gap.

3000 MW(t) HTGR - gas turbine non-intercoolel. Technical evaluation report
This report summarizes all the technical work performed on the 3000-MW(t) 3-loop High-Temperature Gas-Cooled Reactor Gas Turbine design as of June 1979. Although the plant configuration has changed to a 2000-MW(t) 2-loop plant, most of the technical assessments described in this report are still applicable to the 2000-MW(t) plant. The report covers the criteria under which the plant was designed, the technical feasibility problems associated with the plant and their potential solutions, and other potential applications and improvements which could make the gas turbine concept more attractive economically.

Abbreviated RD and D program portfolio selection workbook
A workbook for implementing an abbreviated version of the RD and D portfolio selection methodology described in A Resource Allocation Methodology for Establishing RD and D Budgetary Priorities is presented. The purpose of the abbreviated methodology is to allow a fast, first-cut analysis of a set of programs and to provide a means of discovering important issues that deserve more detailed analysis. The use of the abbreviated methodology in the overall process of evaluating RD and D programs is outlined. The effect of the program on a process is represented by the process model. Those process cost and performance characteristics that are important to the market for an energy product are described. The product cost model takes the cost and performance characteristics and the feedstock price and calculates the cost of producing a unit of energy using the technology in question. The market model takes this cost, the demand for the energy product, and the characteristics of alternative sources of the same product, and specifies the market share captured by the new technology. From this point it is relatively straightforward to infer the impacts of the new technology on the energy system. The benefit model evaluates the impacts in a …

Accuracy of various alternate methods of calculating total mass flow rate for PKL instrumented pipe spool prototype tests in single- and two-phase steam-water flows
Instrumented spool pieces for installation in the piping of the German Primarkreislauf (PKL) test reactor have been designed and tested. The primary objective of the spools is to provide measurements of two-phase steam-water flow parameters (pressure, temperature, velocity) from which mass flow rates can be calculated. Each spool contains a three-beam densitometer, flow turbine, drag screen, and pressure and temperature sensors. The spools were prototype tested in single- and two-phase steam-water flows and the results of the mass flow calculations were compared to known values. The present software calculations of total mass flow in two-phase flows requires data from two instruments only: the flow turbine and drag screen. In this report, mass flow calculations based on other instrument combinations are investigated and compared to the programmed calculations.

Acoustic monitoring systems tests at Indian Point Unit 1. Final report
This report describes the results of a program to test acoustic monitoring systems on Indian Point Unit No. 1 under actual plant operating conditions, less the reactor core. The two types of systems evaluated were the monitoring of acoustic emissions generated by growing flaws and the monitoring of acoustic signals from leaks.

THE ACTIVITY COEFFICIENT OF AQUEOUS NaHCO{sup 3}
The determination of the activity coefficient and related properties of sodium bicarbonate presents special problems because of the appreciable vapor pressure of CO{sub 2} above such solutions. With the development of reliable equations for the thermodynamic properties of mixed electrolytes, it is possible to determine the parameters for NaHCO{sub 3} from cell measurements or NaCl-NaHCO{sub 3} mixtures. Literature data are analyzed to illustrate the method and provide interim values, but it is noted that further measurements over a wider range of concentrations would yield more definitive results. An estimate is also given for the activity coefficient of KHCO{sub 3}.

Advanced materials for alternative fuel capable directly fired heat engines
The first conference on advanced materials for alternative fuel capable directly fired heat engines was held at the Maine Maritime Academy, Castine, Maine. It was sponsored by the US Department of Energy, (Assistant Secretary for Fossil Energy) and the Electric Power Research Institute, (Division of Fossil Fuel and Advanced Systems). Forty-four papers from the proceedings have been entered into EDB and ERA and one also into EAPA; three had been entered previously from other sources. The papers are concerned with US DOE research programs in this area, coal gasification, coal liquefaction, gas turbines, fluidized-bed combustion and the materials used in these processes or equipments. The materials papers involve alloys, ceramics, coatings, cladding, etc., and the fabrication and materials listing of such materials and studies involving corrosion, erosion, deposition, etc. (LTN)

Advanced on-board electric vehicle charger. Final report
The design and development of an on-board charger power module for use in electric vehicles is described. The module operates at 20KHz in a series resonant, half bridge configuration. Circuit design trade-offs, module performance, and solutions to the problems of acoustic noise, maintaining high power factor, circuit protection and operating reliability are discussed. The power module operates from a single phase, 240 V, 50/60 Hz utility line. Average power factor is 0.90; efficiency at maximum power output is 86%. The module is rated to charge a bank consisting of 20 Exide EV-106 batteries (60 cells) to an end voltage of 2.42 V/cell. Physically, the module weighs less than 17 Kg. Projected manufacturing cost at the thousand unit level is $394.00 (1978 dollars).

Advanced photovoltaic concentrator cells. Quarterly technical progress report No. 1, August 28, 1979-November 30, 1979
First quarter activities for a project aimed at demonstrating the technical feasibility of advanced high efficiency concentrator solar converters are described. The goal of the program is to achieve 30% conversion efficiency with a converter operating at 30/sup 0/C under 500 to 1000 SUN AM2 illumination and 25% conversion efficiency with a converter operating at 150/sup 0/C under 500 to 1000 SUN AM2 illumination. The approach is to fabricate two cell, non-lattice matched, monolithic stacked converters using optimum pairs of cells having bandgaps in the range of 1.6 to 1.7 eV and 0.95 to 1.1 eV. The high bandgap cells are to be fabricated using MOCVD or LPE to produce the needed AlGaAs layers of optimized composition, thickness and doping to produce high performance, heteroface homojunction devices, The low bandgap cells are to be similarly fabricated from AlGaSb(As) compositions by LPE. These subcells are then to be joined into a monolithic structure by an appropriate thermal bonding technique which will also form the needed transparent intercell ohmic contact (IOC) between the two subcells. The activities this quarter have been largely focused on the development and study of low bandgap cell structures and attempts to develop suitable techniques for the thermal …
