This describes the main terms and systems covered in a comprehensive labor and material requirements model developed shortly after the U.S. energy crisis of 1973. For most of the 66 electricity production (conversion) technologies covered (e.g., coal, nuclear), quantitative values are shown for energy inputs and energy output. Geothermal flashed steam, 200 MWe complex, is system 64, and only output is shown for it. Values are shown for 25 energy transportation and transmission items. The culmination of the report is an application of the model to the President's Energy Program. While the values here are dated in details, reader can still get quick comparisons among technologies. Other reports from the model are likely in the OSTI collections. (DJE-2005)

A Mark 60B Li-Al target element jammed during discharge from 105-K reactor on March 17, 1975. This failure is described. Fragments from it were analyzed to determine the most probable failure mechanism: The failed target element was single extruded. When a piece of Li-rich dross fell into the mold during casting, it remained intact until coextrusion, when it penetrated or greatly thinned the cladding. The inclusion reacted with moderator during irradiation to corrode the target element and cause swelling, which ultimately caused jamming. All targets should be double extruded. (DLC)

Special experimental field testing and analytical studies were undertaken at Fort Lawton in Seattle, Washington, to study ''close-in'' wave propagation and evaluate data interpretation procedures for a new in situ impulse test. This test was developed to determine the shear wave velocity and dynamic modulus of soils underlying potential nuclear power plant sites. The test is different from conventional geophysical testing in that the velocity variation with strain is determined for each test. In general, strains between 10/sup -1/ and 10/sup -3/ percent are achieved. The experimental field work consisted of performing special tests in a large test sand fill to obtain detailed ''close-in'' data. Six recording transducers were placed at various points on the energy source, while approximately 37 different transducers were installed within the soil fill, all within 7 feet of the energy source. Velocity measurements were then taken simultaneously under controlled test conditions to study shear wave propagation phenomenology and help evaluate data interpretation procedures. Typical test data are presented along with detailed descriptions of the results.

The failure of x-ray diagnostic techniques to accurately detect tumors and other regions of abnormal density in soft tissue has been, for many years, a significant shortcoming of this important technique in medicine. Accelerated heavy particles with plastics for track detection can be used to record small differences in density in soft tissues which may correspond to biological structures and abnormalities. In heavy-particle radiography (HPR), plastic detectors are well suited for recording images since their threshold nature makes them insensitive to spurious low-LET radiations and light secondaries. Sources of error which limit the resolution of HPR are inversely dependent on the atomic mass number (A) of the incident particle. Range straggling, responsible for loss of depth resolution, is proportional to A$sup -$ $sub 0$ $sup 5$ while multiple scattering which degrades lateral resolution is approximately proportional to A$sup -0$.$sup 395$. Recent experiments showing calcification in human blood vessels and soft tissue features in rats underline the potential of HPR as a diagnostic tool. High-resolution, three-dimensional reconstructions are possible using multiple layer plastic detectors and the short exposure time produces blur- free radiographs of specimens whose internal structure may be in motion.

A self-contained, mobile, computer-controlled air-sampling system has been designed and fabricated that also collects and records the data from eight meteorological sensors. The air-samplers are activated automatically when the collected meteorological data meet the criteria specified at the beginning of the data-collection run. The filters from the samplers are intended to collect airborne $sup 239$Pu for later radionuclide analysis and correlation with the meteorological data for the study of resuspended airborne radioactivity and for the development of a predictive model. This paper describes the system hardware, discusses the system and software concepts, and outlines the operational procedures for the system. (auth)

A neutron-detection system was built for the purpose of measuring the neutron flux from an Inertial-Electrostatic Confinement Device located at Brigham Young University. A BF$sub 3$ proportional counter was used for absolute flux measurements and a pair of scintillation detectors was used to compare neutron output under different operating conditions. The detectors were designed to be compatible with the operating conditions of the device and to be able to measure small changes in neutron output. The detectors were calibrated using a Pu-Be source with corrections made for laboratory conditions. Performance of the counting system was checked and data were collected on the neutron flux from the device. (auth)

In order to facilitate the analysis of muonic x-ray spectra, the results of numerical computations of all higher order quantum electrodynamical corrections to the energy levels of muonic atoms are presented in tabular and graphical form. These corrections include the vacuum polarization corrections caused by emission and reabsorption of virtual electron pairs to all orders, including ''double-bubble'' and ''cracked-egg'' diagrams. An estimate of the Delbruecke scattering-type correction is presented. The Lamb-shift (second- and fourth-order vertex) corrections have been calculated including the correction for the anomalous magnetic moment of the muon. The relativistic nuclear motion (or recoil) correction as well as the correction caused by the screening of the atomic electrons is presented in graphs. For the sake of completeness a graph of the nuclear polarization as computed on the basis of Chen's approach has been included. All calculations were made with a two-parameter Fermi distribution of the nuclear charge density. 7 figures, 23 references. (auth)
