Application of uncertainty analysis of ignition performance to the Engineering Test Reactor
The design of future Engineering Test Reactor (ETR) to demonstrate ignition is complicated by the uncertainties in the projected database for ignited plasmas. Application of uncertainty analysis to ETR design utilizing a figure-of-merit defined as the probability of ignition is presented. Performance evaluation from the uncertainty analysis in density-temperature space can locate an optimum operating window for ignition. 11 refs., 5 figs., 3 tabs.

Ortho-para forms of hydrogen, deuterium, and tritium: radiation and self-induced conversion kinetics and equilibria
The theory of the ortho-para transitions in H/sub 2/, D/sub 2/, and T/sub 2/ is developed. Experimental and calculated values of the ortho-para compositions of the three hydrogen isotopes mentioned in the literature are correlated as a function of temperature, and are discussed critically. The kinetics of the radiation and self-induced ortho-para transitions are reviewed. In general, the radiation-induced transitions are more rapid than the self-induced transitions. We estimate (based on data for other systems) that the ..beta..-ray-induced ortho-para transitions in liquid D/sub 2/ or T/sub 2/ would be fast, with a half time on the order of a few minutes. Experiments are proposed to study these transitions in the liquid phase using infrared spectroscopy.

Development of high efficiency solar collector plates. Progress report, January 1, 1975--May 31, 1975
Composite metal technology is used to manufacture intermetallic compound (IC) absorption surfaces and to combine them integrally with a composite metal tube-in-sheet collector plate. Heat treatment process for Al--Ni system was optimized and ..cap alpha.. greater than or equal to 0.95 and epsilon less than or equal to 0.3 were obtained over a broad range of compounding conditions. Studies by SEM show that the Al--Ni IC surface is porous, spongelike and the dimensions of its fine structure are of the same magnitude as the wave length range of solar radiation, explaining at least partially the selectivity. Auger electron spectroscopy indicated that rather continuous aluminum oxide layer covers the fine structure of the Al--Ni. Low carbon steel--copper composite has been shown to be a suitable candidate for the collector plate. Additional work is required to resolve the conflicting requirements of the formation of the IC surface and of the manufacturing of the composite metal tube-in-sheet collector plate.

Cost estimate for electrostatically plugged cusp reactor
A preliminary design of an electrostatically plugged cusp reactor was presented in (UCRL-52142(1976)). The capital costs of the various components of this reactor are estimated and totaled for two different blanket configurations: one having an energy multiplication factor M = 1.2, and the other having M = 1.68. The unoptimized direct capital costs for these cases are found to be about 1400 and 950 $/kWe, respectively.

Wound-counting systems for the measurement and isolation of plutonium and americium
Described are newly developed wound-counting systems which provide a high sensitivity for the detection and quantification of X-ray emissions from wounds contaminated with plutonium or americium; and for the location of deposition of radioactive material within a wound, as required by surgery. The systems are used in the medical facility at the Rocky Flats Plant. Work efforts over the past 20 years have concentrated on improving detection limits by reducing and stabilizing the background counting rate. The developments over the last three years have resulted in a family of instruments with excellent operational characteristics, complementary package design, easy maintenance, and reliable operation. A 13-stage photomultiplier tube system is used.

Short-term aging study at 90/sup 0/C in air: Halthane 73-18 and 73-18A
A ninety-day aging study was performed on Halthane 73-18A to determine the thermal aging effects due to the presence of DABCO, a catalyst. Samples were taken after 14 days, 30 days, 60 days, and 90 days of exposure to air at 90/sup 0/C. Tests used to evaluate aging effects were: ring tensile, differential scanning calorimetry, dynamic dielectric spectroscopy, and solvent swell. Results of tensile tests indicated an increase in tensile properties that peaked at 30 days and decayed to 70 percent loss of peak strength in 90 days. DSC, DDS, and solvent swell data all followed the same trend. Comparative analysis of all data support the hypothesis that the presence of DABCO increases the oxidative cleavage of the polyether chain segment.

Shell structure effects in compressed aluminum
Self-consistent augmented-plane-wave (APW) calculations of the T = 0 aluminum pressure-volume isotherm are reported from normal density to essentially the free-electron limit, and are compared to predictions based on statistical models. Two distinct density regimes are observed in which the APW and statistical model results differ fundamentally. In the first the L shell electrons are pressure ionized and in the second the K shell electrons are pressure ionized. The first of these occurs in the range 5-75 TPa, and the second in the range 2.3 x 10/sup 3/ - 1.1 x 10/sup 5/ TPa.

Measurement of the neutron spectrum from the reaction of 30-MeV deuterons on a thick beryllium target
Measurements were made of the neutron spectrum produced by bombarding a thick beryllium target with 30-MeV deuterons at the University of California, Davis cyclotron. This spectrum is of interest in studying the effect of neutrons on materials to be used in future fusion reactors. The spectrum was inferred from the activation of two sets of detector foils placed at 0/sup 0/ to the deuteron beam, one immediately behind the beryllium target block, and one 40 mm to the rear. A least-squares program was used to analyze the foil activation data to obtain the fluence in each of seven energy groups. The neutron spectrum (fluence/MeV) close to the target decreases continuously with energy in the range 5-32 MeV, while the spectrum 40 mm back has a peak at about 13 MeV. The contribution from neutrons of energies less than 10 MeV is much greater than that found in previous spectral measurements made at large distances from the target. This difference is attributed to the neutrons which are emitted at large angles from the deuteron beam. These observations show the importance of evaluating the neutron spectrum near the target if samples of materials are to be irradiated in this location. (auth)

Robustness of linear estimators to misspecification of trend. Technical report No. 4
The following work is a continuation of an earlier report, Sheshinski (1976). In this paper we continue our examination of the problem of interpolation of air pollution concentrations over an air basin, using a model of a spatially autocorrelated random process. In Chapter I we compare estimators based on a correctly and incorrectly specified constant mean with estimators based on an unspecified constant mean. In Chapter II we compare estimation done with a specified linear trend function to estimation with an unspecified linear trend function. The third chapter deals with a biased partially constrained estimator versus a fully constrained universally unbiased estimator in the presence of a linear trend.

Thermodynamic and stochastic theory of hydrodynamic and power-producing processes
Thermodynamics of the transport processes of diffusion, thermal conduction, and viscous flow at a macroscopic level are developed for the simplest cases of one-dimensional transport in fluids for individual linear and nonlinear processes approaching a stationary non-equilibrium state. Formulation has started of thermodynamic and stochastic theory of combinations of transport processes. Global thermodynamic and stochastic theory of open chemical systems frar from equilibrium is continued with analysis of a broad class of isothermal, multicomponent reaction mechanisms with multiple steady states with assumed local equilibrium. Stationary solutions are obtained of the master equation for single and multi-intermediate autocatalytic chemical systems. A kinetic potential is identified that governs the deterministic time evolution of coupled tank reactors. A second-order response theory was developed to investigate the effects of external periodic perturbations on a chemical reaction at a stable steady state in an open reactor.

Ultrafast x-ray diagnostics for laser fusion experiments
Temporally, spectrally, and spatially resolved x-ray emission diagnostics are important tools in the study of the heating and compression of laser fusion targets by sub-nanosecond laser pulses. The use of the Livermore 15 psec resolution x-ray streak camera to make such measurements is reviewed. Temporal histories of spectrally resolved x-ray emission in the 1 to 10 keV range have been obtained. These data have served to further define the x-ray streak camera as a quantative diagnostic tool and have also provided data relating to the absorption and compression phases of laser heating. The x-ray streak camera has been used in conjunction with a specially designed pinhole imaging system to temporally record images of laser compressed targets with a spatial resolution of approximately 6 ..mu..m. Implosion characteristics are presented for experiments with glass microshell targets. The concept, development, and testing of an ultrafast framing camera for full two-dimensional time resolved imaging is discussed. A prototype camera, based on the image dissection-restoration concept, has achieved an approximately 200 psec frame period with a resolution of 50 ..mu..m.

Review of monitoring instruments for transuranics in fuel fabrication and reprocessing plants. A progress report to the physical and technological programs, Division of Biomedical and Environmental Research, U. S. Energy Research and Development Administration
A comprehensive review of the monitoring instruments for transuranic elements released from nuclear fuel fabrication and reprocessing plants has been compiled. The extent of routine operational releases has been reviewed for the light water reactor (LWR) fuel cycle (including plutonium recycle), the breeder reactor fuel cycle, and the high-temperature gas cooled reactor (HTGR) fuel cycle. The stack monitoring instrumentation presently in use at the various fabrication and reprocessing plants around the country is discussed. Sampling difficulties and the effectiveness of the entire sampling system are reviewed, as are the measurement problems for alpha-emitting, long-lived, transuranic aerosols, /sup 129/I, /sup 106/Ru, and tritium oxide. The potential problems in the HTGR fuel cycle such as the measurement of releases of alpha-emitting aerosols and of gaseous releases of /sup 220/Rn and /sup 14/C are also considered.

Explaining cloud chamber tracks
The operation of many detection devices is usually explained in terms of the ionization tracks produced by particles despite the fact that the corresponding incident wave functions extended over the entire sensitive regions of the detectors. The mechanisms by which the wave function appears to collapse to a track is analyzed here.

High explosive characterization for the dice throw event
An equation of state for detonation products was developed to describe the detonation of large charges of ammonium nitrate/fuel oil (ANFO). The equation of state will be used to predict air-blast and ground-motion effects in the Dice Throw Event. The explosive performance of ANFO is highly dependent on charge size. The equation developed from this work is applicable to heavily confined detonations 101.6 mm in diameter or larger. The equation of state is based on results from experiments in cylinders and hemispheres, and a large field test. The report contains a detailed discussion of the diagnostic and initiation techniques used in these experiments.
