Available in PDF, EPUB and Kindle. Book excerpt: If necessary, the instrument can be used to determine whether a given flux from a reactor is moderated or unmoderated. The experimental model contains proportional counters sensitive to fast or slow neutrons; at a tolerance flux of either, the instrument reads in the neighborhood of halfscale. The model case measures about 6 by 6 by 11 in. Power is derived from five 1.5 volt flashlight cells, and the instrument should operate continuously for more than 60 hours at room temperature. A plutonium source is used for a check of sensitivity, to ensure that the instrument is in calibration before use.

Available in PDF, EPUB and Kindle. Book excerpt: The electronic behaviour of the two D-2X radiacmeters serial nos. I and II, has been examined and found to be satisfactory. (See reports for May 1954, and July 1954) The second step, then, in evaluating the instruments, is the examination of the response of the primary detectors to incident radiation, both neutrons and gamma rays. The procedures described here provide for testing each detector separately, in addition to testing the composite instrument as a whole, thus serving to immediately isolate any misbehavior, and by the same token lending added confidence to the result when the tests are completed.

This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Feasibility studies of nuclear techniques applicable to the determination of geothermal formation temperature and two-phase brine flow downhole have been performed. The formation temperature gauging technique involves injection of fast neutrons into the formation and analysis of the moderated slow neutron energy distribution by appropriately filtered neutron detectors. The scientific feasibility of the method has been demonstrated by analytical computational and experimental evaluation of the system response. A data analysis method has been developed to determine unambiguously the temperature, neutron absorption cross section and neutron moderating power of an arbitrary medium. The initial phase of a program to demonstrate the engineering feasibility of the technique has been performed. A sonde mockup was fabricated and measurements have been performed in a test stand designed to simulate a geothermal well. The results indicate that the formation temperature determined by this method is independent of differences between the temperature in the borehole fluid and the formation, borehole fluid density, and borehole fluid salinity. Estimates of performance specifications for a formation temperature sonde have been made on the basis of information obtained in this study and a conceptual design of a logging system has been developed. The technique for the determination of fluid flow in a well is based on neutron activation analysis of elements present in the brine. An analytical evaluation of the method has been performed. The results warrant further, experimental evaluation.
