  • Ionization Chamber Survey Instrument

    Publication Year: 1957, Page(s):1 - 2
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1848 KB)

    A wide range survey instrument is described. Ranges are 20 mr/hour to 20 r/hour full scale. The thin plastic ionization chamber is easily replaced if contaminated. A three-tube, negative feedback circuit with low battery drain is used. The input resistor selector switch is a new design with high insulation. It is nonmicrophonic and does not cause transients when changing ranges. View full abstract»

  • Regulation of the Individual Dynode Voltages for Photomultiplier Tubes

    Publication Year: 1957, Page(s):3 - 11

    An individual dynode voltage regulating system has been devised which can be mounted on the phototube socket in much the same manner as, and with no more difficulty than, the common bleeder resistance voltage divider. Two types of these regulators have been investigated; the first using silicon diodes, and the second using NE-2 neon tubes. The statistical spread of beta-ray counts was reduced from...

    This paper describes the problem of simulating nuclear reactor start-up with an electronic analog computer. The reactor kinetic equations are discussed and the range that their solution must cover is defined. Source range simulation and alternate methods of simulating the intermediate range are presented. The use of reactor period signal in the intermediate range is described. In the power range, ... View full abstract»

  • Frequency Response Measurements of Power Reactor Characteristics

    Publication Year: 1957, Page(s):15 - 19

    The problem of measuring fundamental characteristics of an inherently stable power-producing reactor is described. It is noted that, in the power range of operation of such a plant, reactivity is a function not only of control rod position, but also of power itself. The mechanism of the latter effect involves the variòus inherent coefficients of reactivity. The result is that conventional, low-po... View full abstract»

    A self-checking system of circuits is expected to provide a new high in operational reliability for the set of radiation monitors described. Developed under sponsorship of the Bureau of Ships, these monitors can readily be adapted for application in any nuclear installation where radiation monitoring must be performed. Three basic channels are provided to measure accurately the gamma radiation in ... View full abstract»

    This paper compares the stability of a given heterogeneous core when operated with a pressurized or subcooled water cooling system in which the power is removed by boiling. In order to provide a basis for comparison the following assumptions are made: 1) reactor power is the same in both cases, 2) the core geometry is the same in both cases, 3) in the case of subcooled operation, coolant flow rate...

  • Designing Heterogeneous Reactors for Stability

    Publication Year: 1957, Page(s):30 - 33
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (996 KB)

    A study of the nonlinear kinetics of heterogeneous reactors can lead to basic design criteria which are useful in designing stability into a given reactor. The design of most reactors is usually based upon other physical parameters such as reactivities, heat transfer surfaces, metallurgical conditions, and operating lifetimes. The question of reactor stability is often deferred on the design sched... View full abstract»

    This paper gives a description of the organization and functioning of the Electronic Division of the Atomic Energy Commission of France. The Division is organized into four sections, Physical Electronics, General Electronics, Industrial Electronics, and Radioactive Isotopes Measurement. The sections are subdivided into groups. There are approximately 200 persons in the Division. Descriptions are g... View full abstract»

  • Design and Use of the Reactivity Computer

    The basic, underlying variable of reactor control is the reactivity. We may regard the reactivity as a measure of the deviation from equilibrium of the neutron balance in a reactor. Or more precisely, we may define the reactivity as the average excess number of neutrons produced per fission that cause further fission, "excess" being the number over and above the one-neutron-per-fission that is req...

    In a unique experiment just completed in Santa Monica Bay, CA, USA, radioactive isotopes were successfully used to trace dispersion of sewage effluent in ocean waters. The results help to establish proper design procedures to insure against beach pollution in a current expansion of the Los Angeles sewage system. To effect the experiment twenty curies of scandium-46 were mixed with sewage effluent ... View full abstract»
