Report discussing microwave attenuation measurement methods and standards. In addition, a relatively new and more precise way of representing and analyzing an attenuation measurement is presented. This in turn permits more rigorous definitions and error analyses than were previously possible. The referral of microwave attenuation measurements to standards operating at lower frequencies is discussed with particular attention to the errors in the referral processes as well as the errors in the standards themselves. Desirable characteristics are listed for attenuators which are suitable for calibration. Measurement methods are classified and described. Comments are made on the accuracy and convenience of various methods, and references are given which cover most of the basic and important research in this field. Key words: Microwave, attenuation, measurements, standards, tutorial.

From introduction: "This report has been prepared in conjunction with the Liquid Metal Fast Breeder Reactor (LMFBR) Follow-On Study. It is the Concept I description of Task I as outlined by Argonne National Laboratory (ANL) in Appendix C of their Follow-On Study Program."

Report discussing the selection, specifications, and use of signal-light colors. It discusses the nature of the problem, and the mathematical representation, recognition, production, control, and use of such colors. The characteristics of different types of chromaticity boundaries and the purpose and effect of the requirement for similarity of chromaticity characteristics are given special consideration. The treatment is varied according to the intended use. The discussion of the control of colors and the section on the use of colors are nontechnical, whereas the section on the production of signal colors is designed for the colorimetrist who is faced with the problem of selecting limit filters or drafting a specification.

The production reactors operated by Douglas United Nuclear, Inc., use treated Columbia River water as the coolant on a once-through basis. Thus, radionuclides formed largely by the neutron activation of river salts are discharged to the river. One method of reducing the quantity of radionuclides in the effluent is to increase the efficiency of parent isotope removal during the coolant treatment process. It was recognized that an alum feed rate of 18 ppM is not necessarily optimum throughout the year. During certain periods it may be well in excess of requirements and overfeeding could be as detrimental to efficient parent isotope removal as underfeeding. Thus, a continuing effort has been underway to find a method for controlling alum feed rate to an optimum value. Flocculent feed rate control based on producing a constant value of the electrokinetic charge (zeta potential) of the floc has been practiced at some water treatment, plants. Although the hypothesis has not had universal acceptance in the water treatment field, laboratory and field data accumulated at Hanford indicated that further evaluation of the approach was warranted. In order to determine the effects of coagulant control based on zeta potential a half-reactor test was initiated at C …

This is a progress report on analysis of thermal data from the Black Rock Desert of northwest Nevada. Hot springs at Soldier Meadows, Fly Ranch, Gerlach, and Pinto Mountains were mapped, and water flows and temperatures measured, by G.W. Berry and G.R. Downs in 1965 and 1966. These data have been studied further by Frank Hadsell (geophysicist) and L.T. Grose (geologist) at the Colorado School of Mines and with the computer facilities of the School of Mines Graduate Research Center, in an effort to determine geothermal power potentials. Power generation by hypothetical Carnot engines has been calculated for the four thermal areas. Data from seven prospect holes at Pinto Mountains have been exploited in plotting geothermal gradients and computing heat flows. It is emphasized that this report is to a large extent an exercise in arithmetic and thermodynamics, fraught with assumptions that may not endure. All of the conclusions are tentative. However, they consider this a valid line of practical research. To the extent that the figures and conclusions are applicable, they are generally encouraging in themselves and in comparison with those of developed geothermal areas, as to the geothermal power potential of Sun acreage in the Black Rock Desert …

From Introduction: "This symposium focuses attention on the growing awareness of the necessity for developing and using better methods for characterizing solids. Many of the most interesting properties of solids depend directly upon these small concentrations of impurities and defects, and the illustration of this is a principal theme of this paper."

This study investigates the cost of shutting down and later starting up the Hanford production complex. Also included are comments on two aspects, other than cost, which are consider to be of great importance. One is the impact of a complete shutdown on the Tri-Cities community. The other is the effect on Battelle`s Pacific Northwest Laboratory. This study encompasses six special shutdown-startup cases. One set of three cases assumes a shutdown of three years; the other set assumes the reactors have been down for a period of five years (from shutdown of the last reactor to startup of the first conventional reactor in the series). within each of the above mentioned sets there are three cases assuming the return of five, six, or seven reactors to weapons production. The sixth and seventh reactors are D and DR respectively. N Reactor is assumed transferred to WPPSS instead of shutdown, and consequently is available for recapture earlier than the conventional reactors. The shutdown schedule is shown in Table IA. The dates, except for the shut down of D Reactor, were picked arbitrarily and can be moved ahead so long as the intervals are kept the same. There is one exception to this …

Report combining National Bureau of Standards Monograph 27 with the references given in Supplement 1 (May 13, 1963) and issued as a single publication to assist users of this material. References concern the field of temperature measurement. These references were collected from two general sources: Scientific and technical literature and government reports. References are divided into a number of categories based on the type of instrument used. Some references to calibration of instruments and to scientific theories upon which temperature measurement is based are also presented.
