Absorption of short-pulse electromagnetic energy by a resistively loaded straight wire

Description: Absorption of short-pulse electromagnetic energy by a resistively loaded straight wire is examined. Energy collected by the wire, load energy, peak load currents, and peak load voltages are found for a wide range of parameters, with particular emphasis on nuclear electromagnetic pulse (EMP) phenomena. A series of time-sequenced plots is used to illustrate pulse propagation on wires when loads and wire ends are encountered. (auth)

Acceptable TRU packaging for interim storage and/or terminal isolation: FY-1977 final report

Description: A program was conducted for the definition and demonstration of acceptable waste packages for defense transuranic waste for interim storage and terminal isolation. During FY-1977, a Contractor Questionnaire was used to gather pertinent data and to assess contractor concerns. This information was integrated into basic application data in the form of a checklist. Conceptual Container Design Specifications were developed by analyzing and evaluating the application data against Federal Regulations … more

Access control system for ISABELLE

Description: An access system based on the one now in operation at the CERN ISR is recommended. Access doors would presumably be located at the entrances to the utility tunnels connecting the support buildings with the ring. Persons requesting access would insert an identity card into a scanner to activate the system. The request would be autologged, the keybank adjacent to the door would be unlocked and ISABELLE operations would be notified. The operator would then select the door, activating a TV-audio li… more

Aerial radiometric and magnetic survey: Death Valley National Topographic Map, Nevada, California

Description: The results of analysis of the airborne gamma radiation survey flown for the region identified as the Death Valley National Topographic Map NJ11-11 is presented in the bound Volume of this report. The airborne data gathered are reduced by ground computer facilities to yield profile plots of the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity… more

Analysis of airborne radiometric data. Volume 4. MAZNAI code for gamma-ray spectral enhancement

Description: In gamma-ray spectrometry measurements, an energy distribution of gamma-rays is viewed by a spectrometer which in turn produces a data set. This data is the result of a complex detection process and generally suffers from loss of resolution due to this detection process and to statistical noise. It is the purpose of the MAZNAI computer program to remove the degrading effects of the detector, to minimize the effects of statistical fluctuations, and to construct an enhanced image spectrum that co… more

Analysis of high-density areas in beryllium hemishells

Description: Small areas of high and low radiographic density in hot-pressed beryllium were studied by macroetching and optical and electron microscopy. The areas were either semispherical or wormlike in shape and were found to be agglomerates of grains markedly coarser or finer than the matrix. (auth)

Analysis of the heat and mass transfer processes of a UO/sub 2/ bubble in sodium for the Fuel Aerosol Simulant Test (FAST). [LMFBR]

Description: The anticipated behavior of uranium oxide vapor bubbles produced by the capacitor discharge vaporization (CDV) method in the Fuel Aerosol Simulant Test (FAST) Facility is discussed on the basis of relatively simple physical models. Results of calculations for the rate of bubble rise and for heat and mass transfer rates are presented. Parametric studies indicate that future analysis efforts should emphasize the diffusion condensation process and the loss of heat from the bubble by radiation. Tra… more

Analysis of the National Energy Plan

Description: The plan is treated by end-use sectors, except for utilities and fuel prices which are presented as separate topics. First, the specific strategies and policies contained in the April 20, 1977, White House Fact Sheet and the April 29, 1977, publication entitled, The National Energy Plan (NEP) are itemized. Next, a further explanation of several of the policies is provided based on information in HR 8631, The National Energy Act. Finally, an analysis of some of the implications of the NEP is per… more

Analysis of the Z dependence of laser generated suprathermal electron temperature

Description: Recent experiments with high Z disks on the Argus facility have exteanded our knowledge of the temperature (inferred from the slope of the hard x-ray spectrum) of laser generated suprathermal electrons, from the previous regime of 1 less than or equal to Z less than or equal to 30 to the Z approx. = 80 regime. The systematic rise of temperature with Z is theoretically analyzed. We believe that material albedoes (electron reflectivity) which increase with Z can account for this behavior, since e… more

Anticipated effect of discharging 242-S evaporator cooling water to the ground

Description: The discharge of cooling water, in the amount of 1 to 1.2 billion gallons per year for a period of three years, from the 242-S Evaporator- Crystallizer to the groundwater system will have a measurable effect on the altitude of the water table beneath and directly adjacent to the 200 West Area of the Hanford Reservation. The probability is high that the water levels in well 299-W23-4 and well 699-35-75 adjacent to the 216-U-10 pond will rise from their present altitude of 478 feet to a minimum a… more

Application of solar energy to industrial drying or dehydration processes. Final report

Description: The application of a solar energy system to the Lawrence, Kansas alfalfa dehydration plant, owned by the Western Alfalfa Corporation, is an attractive opportunity to demonstrate the feasibility of using solar energy to supply industrial process heat. The work undertaken for this project is reviewed. The design parameters of the dehydrator, including the energy consumed by the plant, the airflow requirements of the dehydrator, and the interface between the dehydrator and the solar array are disc… more

Auger study of surface carbon and oxygen on thorium following ion bombardment

Description: The composition of a thorium metal surface has been monitored using Auger electron spectroscopy following Ar/sup +/ bombardment at different temperatures. After extended Ar/sup +/ bombardment, enough contaminated overlayers were removed to expose a surface region containing only thorium, bulk impurities, and imbedded argon. The main impurities, carbon and oxygen, differed in their behavior when the sample was annealed following bombardment. The amount of surface carbon either increased or remai… more

Automation of the Jarrell--Ash model 70-314 emission spectrometer

Description: Automation of the Jarrell-Ash 3.4-Meter Ebert direct-reading emission spectrometer with digital scaler readout is described. The readout is interfaced to a Data General NOVA 840 minicomputer. The automation code consists of BASIC language programs for interactive routines, data processing, and report generation. Call statements within the BASIC programs invoke assembly language routines for real-time data acquisition and control. In addition, the automation objectives as well as the spectromete… more
