Earthquake focal parameters and lithospheric structure of the anatolian plateau from complete regional waveform modeling

Description: This is an informal report on preliminary efforts to investigate earthquake focal mechanisms and earth structure in the Anatolian (Turkish) Plateau. Seismic velocity structure of the crust and upper mantle and earthquake focal parameters for event in the Anatolian Plateau are estimated from complete regional waveforms. Focal mechanisms, depths and seismic moments of moderately large crustal events are inferred from long-period (40-100 seconds) waveforms and compared with focal parameters derive… more

Environmentally Assisted Cracking of Nickel Alloys - A Review

Description: Nickel can dissolve a large amount of alloying elements while still maintaining its austenitic structure. That is, nickel based alloys can be tailored for specific applications. The family of nickel alloys is large, from high temperature alloys (HTA) to corrosion resistant alloys (CRA). In general, CRA are less susceptible to environmentally assisted cracking (EAC) than stainless steels. The environments where nickel alloys suffer EAC are limited and generally avoidable by design. These environ… more

Exploration and Resource Assessment at Mountain Home Air Force Base, Idaho Using an Integrated Team Approach

Description: The U.S. Air Force is facing a number of challenges as it moves into the future, one of the biggest being how to provide safe and secure energy to support base operations. A team of scientists and engineers met at Mountain Home Air Force Base near Boise, Idaho, to discuss the possibility of exploring for geothermal resources under the base. The team identified that there was a reasonable potential for geothermal resources based on data from an existing well. In addition, a regional gravity map … more

Technology and Climate Trends in PV Module Degradation: Preprint

Description: To sustain the commercial success of photovoltaic (PV) technology it is vital to know how power output decreases with time. Unfortunately, it can take years to accurately measure the long-term degradation of new products, but past experience on older products can provide a basis for prediction of degradation rates of new products. An extensive search resulted in more than 2000 reported degradation rates with more than 1100 reported rates that include some or all IV parameters. In this paper we … more

1 mil gold bond wire study.

Description: In microcircuit fabrication, the diameter and length of a bond wire have been shown to both affect the current versus fusing time ratio of a bond wire as well as the gap length of the fused wire. This study investigated the impact of current level on the time-to-open and gap length of 1 mil by 60 mil gold bond wires. During the experiments, constant current was provided for a control set of bond wires for 250ms, 410ms and until the wire fused; non-destructively pull-tested wires for 250ms; and … more

Immobilization of AM-241, Formed Under Plutonium Metal Conversion into Monazite-Type Ceramics

Description: Lanthanum orthophosphate with the monazite structure was proposed on examinations as a suitable matrix for immobilization of future americium-containing liquid wastes, which could be formed in conversion of metallic plutonium into oxide at PA ''Mayak.'' Specimens of monazite non-active ceramics were fabricated from LaPOA powders obtained using a thin-film evaporator by either hot-pressing or cold-pressing and sintering at 900-1300 C. According to electron microprobe analysis (EMPA), scanning el… more

Simulations of Underground Structures Subjected to Dynamic Loading Using the Distinct Element Method

Description: We present results from an investigation into the stability of underground structures in response to explosive loading. Field tests indicate that structural response can be dominated by the effect of preexisting fractures and faults in the rock mass. Consequently, accurate models of underground structures must take into account plastic deformations across fractures and not simply within the intact portions of the rock mass. The distinct element method (DEM) is naturally suited to simulating suc… more

Supercritical heat-exchange field test: field-performance data on shell-and-tube heat exchangers in geothermal service

Description: Presented are results from a binary-cycle test loop. Results cover loop operational problems, overall heat transfer coefficients, LMTD's, and duties for six primary heaters in counterflow having brine in the tubes and hydrocarbon in the shells, and for a condenser. Fluids tested were isobutane and mixtures of isobutane/isopentane; each heated at supercritical conditions and condensed at subcritical conditions.

Activities of the Physical Data Group. [Lawrence Livermore Laboratory]

Description: A system is described in which neutron interaction data are collected from nuclear physics laboratories throughout the world, organized, evaluated, and then stored for easy access in a computer network. Computer codes that use the data to solve neutron interaction problems were also developed. The system supplies reliable up-to-date data, selects specific types of data on request, provides output in a variety of forms (reports, microfiche, microfilm), and functions rapidly and efficiently. 3 fi… more

Acceleration of Polarized Protons to High Energy.

Description: High energy polarized beam collisions will open up the unique physics opportunities of studying spin effects in hard processes. However, the acceleration of polarized beams in circular accelerators is complicated by the numerous depolarizing spin resonances. Using a partial Siberian Snake and a rf dipole that ensure stable adiabatic spin motion during acceleration has made it possible to accelerate polarized protons to 25 GeV at the Brookhaven AGS. Full Siberian Snakes and polarimeters are bein… more

Resilient Control System Execution Agent (ReCoSEA)

Description: In an increasingly networked world, critical infrastructure systems suffer from two types of vulnerability. The first is the traditionally recognized problem of monitoring the systems for faults and failures, recognizing and analyzing data, and responding with real understanding to the problems of the system. Increasingly complex systems create the opportunity for single points of failure to cascade when inaccurate assessment of system health increases response time or leads to faulty analysis … more

Assessing the Feasibility of Using Neutron Resonance Transmission Analysis (NRTA) for Assaying Plutonium in Spent Fuel Assemblies

Description: Neutron resonance transmission analysis (NRTA) is an active-interrogation nondestructive assay (NDA) technique capable of assaying spent nuclear fuel to determine plutonium content. Prior experimental work has definitively shown the technique capable of assaying plutonium isotope composition in spent-fuel pins to a precision of approximately 3%, with a spatial resolution of a few millimeters. As a Grand Challenge to investigate NDA options for assaying spent fuel assemblies (SFAs) in the commer… more
