Announced data for US and French underground nuclear explosions indicate that nearly all detonations have occurred within one or two tenths of a second after the minute. This report contains ISC origin-time data for announced explosions at two US test sites and one French test site, and includes similar data for presumed underground nuclear explosions at five Soviet sites. Origin-time distributions for these sites are analyzed for those events that appeared to be detonated very close to the minute. Particular attention is given to the origin times for the principal US and Soviet test sites in Nevada and Eastern Kazakhstan. The mean origin times for events at the several test sites range from 0.4 s to 2.8 s before the minute, with the earlier mean times associated with the Soviet sites and the later times with the US and French sites. These times indicate lower seismic velocities beneath the US and French sites, and higher velocities beneath the sites in the USSR 9 figures, 8 tables.

A semi-phenomenological formula is proposed for the change of emittance of a self-pinched beam which is not matched to its equilibrium radius. Near equilibrium this formula, coupled with an envelope equation, yields the damped sausage oscillations observed in simulation and experiments. For a beam which is injected cold (no transverse velocity spread), the formula coincides with the analytically calculated initial growth of emittance. The basic theory is developed here and used to compute the linear damping rate for several current profiles. The resultant non-linear increase in equilibrium quantities is also calculated in lowest order of the degree of mismatch.

Level population as a function of laser pulse envelope area for an atom which could be approximated as a two level system was measured. An ideal two-level system under the action of an oscillating force is one of a few quantum mechanical systems for which the time-dependent Schroedinger equation can be solved exactly. The solution predicts that the population of the upper state, for a system which was entirely in the lower state at t = 0, varies as sin/sup 2/A, where A = ..integral../sub 0//sup t/ ..cap omega..(t) dt, and ..cap omega.. = e epsilon/sub 0/(t) x/sub 12//h-bar.

The work described in this paper is part of a leaching study being conducted for the Battelle Pacific Northwest Laboratory's Waste Isolation Safety Assessment Program. Simulated high-level reactor waste glass was leached with three solutions, one of which was a saturated-salt brine. Because chemical separation of Np and Pu using organic extraction or anionic exchange is not effective for the brine samples, a procedure has been developed to first separate neptunium and plutonium from high concentrations of brine before proceeding with an extraction of neptunium from plutonium. Samples were equilibrated with tracers, Np and Pu were co-precipitated with La(OH)/sub 3/, and interfering ions were removed by washing the hydroxide precipitate with water. Pu and Np were separated by reducing Pu to Pu/sup 3 +/ and extracting the Np/sup 4 +/ into thenoyltrifluoroacetone; control of oxidation states and contaminant concentration is critical.

The purpose of this work is to demonstrate whether there is a cost benefit to Pacific Gas and Electric Company in replacing the present iron catalyst/caustic/peroxide system used in the direct contact condenser units versus an alternative approach using surface condensers and the Stretford System.

The strain degradation of critical current density has been analytically and experimentally investigated for multifilamentary superconducting composites produced in a bronze core geometry. Analytic results were obtained from a computer program (MAXIMSUPER) which predicts the stresses and strains in composites as a result of thermal and axial loading. Tensile test data for Nb/sub 3/Sn are described. It is believed that the strain dependence of the critical current found in Nb/sub 3/Sn is due to strain enhanced martensitic transformation.

This report on the Sensitivity of Mission Analysis and Trade-off Studies provides an analysis of the sensitivity of the results of previous mission analysis and performance specification studies to the possible variations of the values of significant parameters as projected to the year 1985. These parameters include vehicle usage by purpose, driving cycles, trip lengths, ownership projections, and life-cycle costs. Tabulated data are included from calculations with variations in these parameters. (LCL)

The maximum temperature drop that could occur across the mounting plate or instrument holder is about 9/sup 0/F. This is based on conservative data and assumptions. Gamma heating was estimated from calculations for 55 MW operation; the value used was 0.015 Watts/gram of metal. The mounting plate is the restriction orifice on top of the upper end box on the center fuel assembly. The instrument holder is bolted to the top of this plate. Only steady state operation is considered.

Four features of the thermal control plans for the Mirror Fusion Test Facility (MFTF) magnet are described. First, the proposed cooldown and warmup schedules for MFTF and the procedure for regenerating external cooling surfaces is outlined. Then the design of an external quench resistor, based on an estimate of the superconductor's maximum temperature, is discussed. A computer model of liquid helium circulation used to aid in choosing pipe for the LHe lines is explained.

The dynamic viscosity was measured for six anhydrous silicate melts, obtained by fusing various rocks collected from the Department of Energy's Nevada Test Site, from 1393 to 1953 K at 150 kPa. These silicate melts exhibit Newtonian behavior in this temperature interval. Experimental results indicate that tuff viscosity > alluvium viscosity > basalt viscosity. At 1673 K, viscosities of Schooner tuff (Ue20..mu..-330'), alluvium (U10ba), and Danny Boy basalt (Ue18q No. 2) are 28,460 Pa.s, 4,820 Pa.s, and 12.6 Pa.s, respectively. Activation energies for viscous flow in the interval between 1393 and 1953 K range from 268 to 393 kJ/mole.

The potential contribution of future geopressured energy - especially methane - to the US and the world's needs is examined through several scenarios. Although such production may not become competitive, if it does the eventual producible reserves from the Gulf Coast region seem likely to fall between 100 and 10,000 quads. The world's potential from similar resources is not known but may well be 10 times as great. The contribution to the projected future demand for hydrocarbons is found to become substantial in most of the success scenarios. The potential impact on fuel imports and their future prices is discussed. Although technical uncertainties are far too great at present for accurate projections, this could change rapidly as field data becomes available from DOE's R and D program.

A number of compounds have been screened as potential scale control agents by examining their effect on the precipitation of silica from Magmamax No. 1 brine. The substances were tested using the Lawrence Livermore Laboratory scale-control test system at the Niland, California, test site. Solutions of the test substances were injected into flowing brine at approx. 200/sup 0/C, the brine was flashed at 125/sup 0/C, and then the kinetics of solids and silica precipitation from effluent brine held at 90/sup 0/C were measured. Compounds tested include a variety of cellulose derivatives, ethylene oxide polymers, several polyethoxylated surfactants, and a phosphonate. The ethylene oxide moiety was confirmed as the source of activity in substances that inhibit the precipitation of silica at 90/sup 0/C, and the polyethylene glycols in the molecular weight range of approximately 10,000 to 100,000 are the most effective. A brief, in-plant scaling test with the most promising precipitation inhibitor showed that, although it significantly retarded scaling at 90/sup 0/C, there was no improvement at 125/sup 0/C or higher, and at 125/sup 0/C there may have been a slight increase in scaling rate.
