Abstract: This technical memorandum describes an automatic tester and recorder as it is used in obtaining fusing time information from electrical fuses for subsequent analysis in the IBM 704 computer.

An all-transistor system has been developed to be used in measuring the reactivity of the reactor in the Sandia Engineering Reactor Facility. In operation, the system triggers a pulsed neutron source (PNS) in the reactor and counts the resulting neutron flux, thus giving a measure of the time constant of the reactor. The counting is done in eleven time-sequenced counting channels. The reactor time constant is a measure of the reactor reactivity.

This report presents a description of and operating instructions for APOTA--a device which automatically tracks any signal-emitting source within the 190 to 250 MC band. APOTA is especially useful for telemetering applications.

The need for special high velocity shock testing is pointed out and equipment that has been developed to meet these needs is discussed. The concept of velocity-change and its importance in shock-testing technology is brought out. The three types of equipment discussed are: accelerated drop testers, pneumatic actuators, and air guns. Examples of each type and their capabilities and limitations are presented.

Abstract: This memorandum describes the components and presents the operating and maintenance instructions for the 12-inch transonic wind tunnel analog-to-digital data gathering systems.

Abstract: Force, moment, and center of pressure information are presented for four models of the Hi-Lo configuration.

From introduction: The objectives of the technical effort are to identify and characterize agricultural energy demands that can effectively use P/V power systems and to determine performance and cost-estimates for the designs.

From abstract: The PT-750 is designed to be used in conjunction with a production tester which requires automatic recording of test data. This manual provides a source of procedures and reference material necessary in automatic recording and in use of the PT-750.

From abstract: This report is a technical and economic evaluation of five representative cell laydown techniques with the final goal being a determination of which was most promising from a cost performance basis.

Abstract: "The pressure drop associated with the flow of air through a cylindrical bed of spherical pebbles has been investigated experimentally. The results of this investigation are reported here."

Forword: The International Symposium for Packaging and Transportation of radioactive materials held at Albuquerque, New Mexico, January 12 to 15, 1965, was a joint effort on the part of the Sandia Corporation, the Albuquerque Operations Office, and the Headquarters, U.S. Atomic Energy Commission.

Foreword: There has been relatively little work reported on deriving quantitative estimates of the degradation to a man-machine system resulting from human errors. One approach, used in the Reliability Department of Sandia Corporation, is presented here as an example of how such estimating can be done.

Abstract: This document outlines the essentials of the planning and action necessary for the recovery of radioactive contaminated equipment following a radiological disaster. It lists the records which should be collected before a disaster and discusses the training of personnel for recovery teams. Radiation doses, radiation indicators, and protective clothing are all treated in a general fashion. Procedures are given for the actual recovery of equipment, with emphasis on personnel safety. Decontamination techniques and materials are then discussed. Graphs and simple calculations are presented for determining safe work limits and radiation doses under varied conditions. A list of typical sources for radiological supplies and a brief bibliography are also included.

This report on the RFD-1 optical data and external fuel-element experiment includes a description of the instruments and test components used, a presentation of the data obtained, an explanation of the methods of data reduction employed, and a statement of the conclusions derived. It covers the theory, design, qualification tests, flight-test data, and results of the external fuel-element experiment. Also presented is a theoretical analysis of observed versus predicted ablation times and altitudes for the external fuel elements. In addition, this report presents recommendations for improvements to data acquisition and reduction methods in future, similar flight tests.

From abstract and summary: Project Stagecoach consisted of the detonation of three 40,000-pound charges. Blocks of cast TNT were stacked to resemble a sphere and, the whole center-detonated.

From abstract: This report presents a preliminary evaluation of design concepts for the eventual sealing of the shafts, drifts, and boreholes at the Waste Isolation Pilot Plant Facility. The purpose of the seal systems is to limit the flow of water into, through, and out of the repository.

This report describes the Sandia Corporation participation and results related to Project Buckboard: the detonation of three 40,000-pound and ten 1000-pound high-explosive charges in basalt rock to establish depth -of-burst curves.

Forward: The Final Report summarizes the findings and project work in conjunction with the "Photovoltaic" Applications Definition and Photovoltaic System Definition Study in the Agricultural Sector" under Contract Number 07-6951.

From abstract: Photovoltaic modules and arrays are tested in the PASTF, along with power conditioning units and energy storage equipment related to photovoltaic systems.

Abstract: Bechtel National, Inc. has conducted a study of the requirement for, and a preliminary design of, a photovoltaic central station test facility.

Abstract: The APAR-3G system is an automatic programming, controlling and recording machine which is readily adaptable to a wide variety of automated data acquisition and constrol system applications. It is physically and logically modular to permit the assemby of minimum or maximum capability machines. This system can perform the necessary acquisition and control in a typical factory environment and can generate an output (for data reduction) which is compatible with available computer systems.

From background: The solar system design described in this report is for a residential two story house located in the Northeast region of the country typified by the Boston/Madison weather environment. A side-by-side photovoltaic/thermal system design was developed for the application.

A control system has been developed that uses a carrier signal imposed on an existing ac power circuit to transmit commands. This system was specifically developed to control an entire solar collector field by sending sun-tracking information to the trough collectors or by commanding them to assume safe positions (STOW) if out-of-limit conditions were encountered. Objectives were to develop a control system that operates reliably and has enough functions to control an entire collector field, yet do it at less cost than for conventional approaches. Development, design, operating characteristics, and field testing and results of the new system, the Power Cable Carrier Control (PC³) System are described.
