Solving The Longstanding Problem Of Low-Energy Nuclear Reactions At the Highest Microscopic Level - Final Report

A 2011 DOE-NP Early Career Award (ECA) under Field Work Proposal (FWP) SCW1158 supported the project “Solving the Long-Standing Problem of Low-Energy Nuclear Reactions at the Highest Microscopic Level” in the five-year period from June 15, 2011 to June 14, 2016. This project, led by PI S. Quaglioni, aimed at developing a comprehensive and computationally efficient framework to arrive at a unified description of structural properties and reactions of light nuclei in terms of constituent protons and neutrons interacting through nucleon-nucleon (NN) and three-nucleon (3N) forces. Specifically, the project had three main goals: 1) arriving at the accurate predictions for fusion reactions that power stars and Earth-based fusion facilities; 2) realizing a comprehensive description of clustering and continuum effects in exotic nuclei, including light Borromean systems; and 3) achieving fundamental understanding of the role of the 3N force in nuclear reactions and nuclei at the drip line.

Hyperspectral Sensors Final Report CRADA No. TC02173.0

This was a collaborative effort between Lawrence Livermore National Security, LLC as manager and operator of Lawrence Livermore National Laboratory (LLNL) and Science Applications International Corporation (SAIC), National Security Space Operations/SRBU, to develop long-wave infrared (LWIR) hyperspectral imaging (HSI) sensors for airborne and potentially ground and space, platforms. The overarching purpose of the CRADA project was to facilitate the transfer of the necessary technology from LLNL to SAIC thereby allowing the U.S. Government to procure LWIR HSI sensors from this company. The purpose of the initial activities involving BIG GREEN sensors was to meet the customer’s delivery schedule for all of the BIG GREEN sensors. BIG GREEN is a complex and sophisticated instrument, and the requisite technology must be imparted to SAIC to allow them to successfully produce the instrument. It was expected that in the first few months of joint work, sensor models (performance, structural, thermal and optical) would be provided to SAIC. Additionally, existing drawings, assembly procedures, test procedures, test equipment definitions, software descriptions and code, and complete Bills of Material (BOM) would be provided. SAIC would analyze the models, purchase material per the BOM, create its own set of production drawings, models and procedures, and identify areas of concern or where further information transfer is required.

Multi Scale Modeling of Liquid Metal Embrittlement Mechanisms: CRADA Final Report

The roles and effects of Hg atoms at surfaces, and grain boundaries of fcc Fe were examined by analytical and phenomenological calculations to sort out various critical paths and bottlenecks of the basic mechanistic understanding of liquid mercury metal embrittlement of steels. LANL used phenomenology and simple simulations to explore various decohesion and diffusion scenarios for Hg.

Power & Water Facility and Infrastructure Planning: CRADA Final Report

Los Alamos National Laboratory (LANL) has developed software and expertise for planning power grids and for examining the human resource issues for a nuclear power program. These programs, and other LANL software innovations, can offer an efficient manner in which to assist the power and water generation industries in both developed and undeveloped countries.

Magneto Inertial Fusion Plasma Target Collaboration: CRADA Final Report

The Participant and Los Alamos National Laboratory (LANL) investigated possible paths for compression of plasma targets in Magneto Inertial Fusion (MIF) regimes. MIF involves the addition of a magnetic field to Inertial Fusion type plasma targets, potentially improving energy confinement. This technique could reduce the power, precision, and cost required to compress and heat plasma targets to fusion relevant conditions, leading to a lower cost path to a fusion energy source. MIF regimes are intermediate between magnetic fusion energy and inertial fusion energy approaches. LANL is pursuing the creation of a MIF compatible magnetized plasma target with long enough lifetime to compress it inside a solid cylindrical, flux-conserving shell. The Participant also requires a similar plasma target for use with a novel acoustic wave compression scheme.

Improving RF Characteristics of Wire: CRADA Final Report

Los Alamos National Laboratory (LANL) and the partner investigated microwave loss characteristics of coated wire made at LANL. The characterization of the coatings was performed using a microwave cavity. The loss characteristics of the coatings was compared to those of bare Cu and Ag wires of the same diameter.

Energy-Efficient Purification of Bio-Fuels and Bio-Chemicals Using a Novel Advanced Polymeric Membrane System: CRADA Final Report

The team collaborated to develop, demonstrate and move toward the commercialization of a pervaporation membrane system, which reduces the energy required for product isolation from dilute fermentation broths. Avoiding the energy consumption associated with the latent heat of vaporization for water was the key benefit. Essentially, this work isolated high boilers from dilute feeds without evaporating water. These activities lead to the development, fabrication, and demonstration of proprietary, advanced polymer membrane cartridges that dramatically reduce the cost of bio-chemical and bio-fuel manufacture.

Non-precious Metal Cathode Catalysts: CRADA Final Report

The stringent cost and performance targets of an automotive fuel cell required either a more active precious metal catalyst or a lower cost catalyst than the standard platinum catalyst. Non-precious metal catalysts (NPMCs) are a low cost alternative, but the oxygen reduction reaction activity required electrodes of unreasonable thickness to meet the performance targets. NPMCs also suffer from low durability in the acidic and oxidative environment of the fuel cell cathode. The goal of the collaboration between UTC Power Corporation (UTCP) and Los Alamos National Laboratory (LANL) was to increase the activity and durability of NPMCs to meet the needs of the automotive industry.

Mimetic Finite Differences and Algebraic Multilevel Methods for Reservoir Performance Predictions: CRADA Final Report

The need to better predict and control reservoir performance is driving the development of increasingly sophisticated reservoir models that use unstructured general polyhedral grids to capture highly detailed stratigraphy. However, both discretization methods and scalable iterative solution algorithms for these situations are an active area of research. In this work we compared the performance of a new Mimetic Finite Difference (MFD) method with two new Mixed Finite Element methods, and LANL and the CRADA Participant investigated the performance of Los Alamos National Laboratory’s algebraic multigrid code on realistic flow problems. Furthermore, uncertainty quantification requires rapid evaluations of reservoir models. To do this, fine-scale reservoir models need to be coarsened and yet important fine-scale features and processes that have a significant impact on flows need to be preserved. To this end, we investigated the use of multi-resolution methods, such as the Multilevel Multiscale Mimetic (M3) method, to coarsen reservoir models.

Anti-Perovskite Thin films for Battery Applications: CRADA Final Report

The latest development in the solid electrolytes for Li-based batteries indicated that anti-perovskites such as LI 3 OCI have the highest Li concentration of all Li-based electrolytes. Furthermore, this class of materials displays superionic conductivity, low activation energy, and very low electronic conductivity. In this project, we studied anti-perovskite Li-based electrolytes in the thin film format.

Nautical Dawn - Wide-area Motion Imagery and RF Compressive Sensing Applications: CRADA Final Report

The global information grid (GIG) provides access to massive amounts of data from a vast number of intelligence, surveillance, and reconnaissance (ISR) sensors and sources. A significant challenge exists in the actual exploitation of the sensor data. Sensor data is often large, and in the present paradigm analysts extract information from it in raw form. This approach taxes the limited network-bandwidth of the GIG, since the raw data must be transmitted to analysts prior to processing. The parties proposed a new approach to advance the rate of production of actionable information from ISR data, one that extracts information from raw data closer to the sensors. This research developed an information-centric capability that uses a distributed compressive sensing and processing (DCSP) framework.
