ERA-40 SST and Sea Ice Concentration Data

Description: The lower boundary condition of sea surface temperature (SST) and sea-ice concentration (sic) is a critical forcing of the lower frequencies in multi-decadal global atmospheric reanalyses such as ERA-40. Partly in response to the ERA-40 project, new SST/sic data sets have been developed that are considerably improved over those available to the first-generation reanalyses. This paper documents the input SST/sic data sets and the processing that created the daily SST/sic specification for the ER… more

Theoretical Model for the EM Effects Induced by High-Energy Photons (Gamma, X-ray) in Dielectric Materials and Electronic Systems

Description: During last twenty years, a number of models have been used to calculate the change of conductivity and dielectric strength in materials caused by the passage of high-energy photons, such as Gamma-rays and X-rays. In these models, the electromagnetic fields generated in the electronic system created by the high-energy photons have not been investigated. That is, the solution of Maxwell's equations has not been obtained for these kinds of problems. We constructed a theoretical model, described b… more

Almost Optimal Interior Penalty Discontinuous Approximations of Symmetric Elliptic Problems on Non-Matching Grids

Description: We consider an interior penalty discontinuous approximation for symmetric elliptic problems of second order on non-matching grids in this paper. The main result is an almost optimal error estimate for the interior penalty approximation of the original problem based on the partition of the domain into a finite number of subdomains. Further, an error analysis for the finite element approximation of the penalty formulation is given. Finally, numerical experiments on a series of model second order … more

Liquid Scoping Study for Tritium-Lean, Fast Ignition Inertial Fusion Energy Power Plants

Description: In a thick-liquid protected chamber design, such as HYLIFE-II, a molten-salt is used to attenuate neutrons and protect the chamber structures from radiation damage. The molten-salt absorbs some of the material and energy given off by the target explosion. In the case of a fast ignition inertial fusion system, advanced targets have been proposed that may be Self-sufficient in the tritium breeding (i.e., the amount of tritium bred in target exceeds the amount burned). These ''tritium-lean'' targe… more

Marangoni Convection Induced Ripple on Grazing Incidence Liquid Metal Mirror (GILMM) Used for Laser Inertial Fusion Energy

Description: A spatial variation of temperature in the sodium film on the surface of the grazing incidence liquid metal mirror (GILMM) will give rise to convection due to the temperature dependent variation in surface tension. This is called thermal capillary convection or the Marangoni effect and causes the surface to have ripples or waves. This note estimates the magnitude of this effect and finds, with care, design parameters can be chosen to make the resulting ripples sufficiently small so that a laser … more

Partial Re-vegetation of the Dust and Blowing-Sand Source Area: A proposal for use of a 175 K$ SEP Fine

Description: We propose using the 175 K$ SEP money to stabilize approximately 300-340 acres located to the southwest of the 200 West Expansion Area fence. We propose a procedure that relies on drill seeding a mixture of perennial native grasses followed by truck application of a soil fixative such as Soil Master. This effort would compliment FDH/Duratek activities planned for inside the 200 West fence lines. Assuming that both efforts are successful, the result would be between 2,000 and 2,500 meters of sta… more

Isotopic Tracing of Fuel Components in Particulate Emissions from Diesel Engines using Accelerator Mass Spectrometry (AMS)

Description: Accelerator mass spectrometry (AMS) is an isotope-ratio measurement technique developed in the late 1970s for tracing long-lived radioisotopes (e.g., {sup 14}C half life = 5760 y). The technique counts individual nuclei rather than waiting for their radioactive decay, allowing measurement of more than 100 low-level {sup 14}C samples per day (Vogel et al, 1995). The LLNL AMS system is shown in Fig.1. The contemporary quantity of {sup 14}C in living things ({sup 14}C/C = 1.2 x 10{sup -12} or 110 … more

Update of Environmental and Safety Analyses for the National Ignition Facility: Using a New Model to Track Target Material Usage

Description: The purpose of this paper is to report the methodology and assumptions, data, and results of calculations concerning safety and environmental issues related to excursions to currently planned NIF operations. Many possible uses of NIF have been suggested over the years. While some of these possible uses have been adopted into the baseline plans for NIF, many others have not. While we do not yet know all of the possible approved uses for NIF, one of the items that would bear on whether a certain … more

Analytical Solutions for Sequentially Reactive Transport with Different Retardation Factors

Description: Integral transforms have been widely used for deriving analytical solutions for solute transport systems. Often, analytical solutions can only be written in closed form in frequency domains and numerical inverse-transforms have to be involved to obtain semi-analytical solutions in the time domain. For this reason, previously published closed form solutions are restricted either to a small number of species or to the same retardation assumption. In this paper, we applied the solution scheme prop… more

Switchyard Enclosure Seismic Criteria Calculations

Description: Finite Element Analysis (FEA) was conducted on these four Beam Enclosure Assembly drawings: (1) AAA97-108954 (Quad); (2) AAA97-108981 (Quad Intermediate); (3) AAA98-101193 (Bundle); and (4) AAA97-108982 (Double Quad). Each drawing chosen represents one of the four enclosure types: Quad, Quad Intermediate, Bundle, and Double Quad. They were chosen because they have the longest length between supports for their type and are therefore the worse case condition from the standpoint of seismic induced… more

Novel Concepts for Damage-Resistant Alloys in Next Generation Nuclear Power Systems Phase II Annual Report

Description: The discovery of a damage resistant alloy based on Hf solute additions is the highlight of the Phase II research. The damage resistance is supported by characterization of damage microstructures, measurement of radiation-induced grain boundary compositions and measurements of cracking in irradiated 316SS alloys with oversize solute additions. The addition of Hf reduced the impact of radiation for two processed conditions, a standard condition and a modified (optimized) condition. Pt additions r… more

What is Air? A Standard Model for Combustion Simulations

Description: Most combustion devices utilize air as the oxidizer. Thus, reactive flow simulations of these devices require the specification of the composition of air as part of the physicochemical input. A mixture of only oxygen and nitrogen often is used, although in reality air is a more complex mixture of somewhat variable composition. We summarize some useful parameters describing a standard model of dry air. Then we consider modifications to include water vapor for creating the desired level of humidi… more

Mechanical Engineering Safety Note: Analysis and Control of Hazards Associated with NIF Capacitor Module Events

Description: The NIF capacitor module was reviewed with respect to pressure venting and shrapnel containment during failures. A modified module concept was proposed that would adequately vent the pressure, yet be effective at containing shrapnel. Two large vents are provided on each side of the module. These have fixed vent areas, and are immediately accessible for pressure venting at the beginning of a pressure transient. A shrapnel shield is located on the outside of each vent opening forming a chute. The… more

Hydrodynamic Theory of Atomic Mixing in Multicomponent Gases and Plasmas

Description: Atomic mixing in multicomponent gases and plasmas is usually described as a diffusional process. The diffusional description is an approximation to a more general dynamical description in which the motion of each individual species or material is governed by its own momentum equation, with appropriate coupling terms to represent the exchange of momentum between different species. These equations are not new, but they are scattered in the literature. Here we summarize the form of these species m… more
