Nuclear Structure Research at the Triangle Universities Nuclear Laboratory. [Final report, 1 April 1988 to 4 May 1998]
Much of the research is focused on symmetries and symmetry breaking. The authors have emphasized the effects of the many body system on symmetry breaking--the parity violation studies. A parallel interest lies in the effects of symmetry breaking on the many body system (as manifested in the statistical distributions characterizing the system). Another major activity has involved few nucleon scattering. The primary technical efforts are in low temperature targetry. The service activity for the nuclear science community is Nuclear Data Evaluation. Results achieved in these areas during the period of the grant are summarized. Details are given in the 10 annual progress reports, 10 Ph.D. dissertations, and approximately 150 publications.

NWCC Transmission Case Study III
OAK-B135 Transmission System Improvements for Wind Energy Development in the Upper Midwest and Great Plains: Opportunities and Obstacles. This case study set out to ascertain the validity of three assumptions from the perspectives of stakeholders involved in wind energy and transmission issues in the Upper Midwest and Great Plains. The assumptions, and the stakeholders' reactions to each, are summarized below: Assumption 1--Transmission system improvements would provide significant benefits to the electricity network and its customers. Respondents acknowledge the potential for overall system benefits in the form of reduced line losses, improved grid stability and reliability, and enhanced ability to conduct spot market transactions. They also agree that these benefits relate to specific regional needs. However, there is disagreement over the extent of other benefits such as efficiency gains and cost savings from reduced line losses. Further, environmental and community interest groups point out that none of these benefits are realized without significant financial, environmental and social costs. Assumption 2--The benefits of transmission improvements would be helpful, but not confined, to wind power. All respondents agree that wind energy could benefit from transmission system improvements. But they also acknowledge, reluctantly, in the case of environmental stakeholders, that the benefits of an …

Occurrences at Los Alamos National Laboratory: What can they tell us?
The authors analyzed the evolution of institutional and facility response to groups of abnormal incidents at Los Alamos National Laboratory (LANL). The analysis is divided into three stages: (1) the LANL response to severe accidents from 1994 to 1996, (2) the LANL response to facility-specific clusters of low-consequence incidents from 1997 to 1999, and (3) the ongoing development of and response to a Laboratory-wide trending and analysis program. The first stage is characterized by five severe accidents at LANL--a shooting fatality, a forklift accident, two electrical shock incidents, and an explosion in a nuclear facility. Each accident caused LANL and the Department of Energy (DOE) to launch in-depth investigations. A recurrent theme of the investigations was the failure of LANL and DOE to identify and act on precursor or low-consequence events that preceded the severe accidents. The second stage is characterized by LANL response to precursor or low-consequence incidents over a two-year period. In this stage, the Chemistry and Metallurgy Research Facility, the Los Alamos Critical Experiments Facility, and the Los Alamos Neutron Science Center responded to an increase in low-consequence events by standing down their facilities. During the restart process, each facility collectively analyzed the low-consequence events and developed …

October 1999 Groundwater Sampling and Data Analysis, Distler Brickyard Site, Hardin County, Kentucky
This report describes the results of a sampling event conducted at the Distler Brickyard Superfund Site, Hardin County, Kentucky, October 1999. The purpose of the sampling event was to evaluate the extent of natural biodegradation of chlorinated aliphatic hydrocarbons (CAH) occurring at the Site. Sampling locations were selected to evaluate three areas of the suspected CAH plume: the source area, an axial cross-section, and a downgradient transect. Due to inadequate recharge to and the poor physical condition of some monitoring wells at the Site, the sampling approach was modified to reflect wells that could be sampled. Results indicate that natural anaerobic degradation of chlorinated aliphatic hydrocarbons is occurring in the presumed source area around monitoring well GW-11. The primary contaminant of concern, trichloroethene, migrates downgradient from the source area into the Coarse Grained Alluvium Aquifer at concentrations slightly greater than the Maximum Contaminant Level (MCL). Based on the available, the following hypothesis is proposed: the source area has been remediated through soil removal activities and subsequent anaerobic reductive dechlorination. If this is the case, this Site may be a good candidate for implementation of a monitored natural attenuation remedy. However, more data are necessary before this hypothesis can be confirmed.

Orthogonal tensor decompositions
The authors explore the orthogonal decomposition of tensors (also known as multi-dimensional arrays or n-way arrays) using two different definitions of orthogonality. They present numerous examples to illustrate the difficulties in understanding such decompositions. They conclude with a counterexample to a tensor extension of the Eckart-Young SVD approximation theorem by Leibovici and Sabatier [Linear Algebra Appl. 269(1998):307--329].

Overview of Chamber and Target Technology R&D for Heavy Ion Fusion
In 1999, the Department of Energy's (DOE) Office of Fusion Energy Sciences (OFES) added an inertial fusion energy (IFE) element to its Virtual Laboratory for Technology (VLT). The scope of the element of the VLT includes the fusion chamber, chamber/driver interface, target fabrication and injection, and safety and environmental assessments for IFE. Critical issues have been identified and an integrated R&D plan for the next 4-5 years has been written to coordinate the research in these areas. This paper provides an overview of the U.S, research activities addressing the critical issues.

Phosphazene Silicate Nanocomposites. A Survey of Materials Properties and Synthetic Methods Using New Catalysts
In the ceramics community, manipulation of synthetic conditions such as the choice of acid, base or ionic species as catalysts, aging of precursor solutions, and choice of sintering temperatures in the formation of silicate networks are known to produce radically different glass and ceramic morphologies.1 Implementation of these approaches has been attempted for some organic polymer based hybrid nanocomposites2 but not for polyphosphazene silicate composites. The desire to create unique and novel network morphologies became the impetus for establishing new catalysis protocols. The surprising inability to reproduce the mechanical properties of a well-established benchmark composite material from the literature,3 was one principal driver that initiated this in-depth investigation into the roles that the nature and amount of catalysts play in the production and physical properties of these composites.

Photoemission and the origin of high temperature superconductivity
The condensation energy can be shown to be a moment of the change in the occupied part of the spectral function when going from the normal to the superconducting state. As a consequence, there is a one to one correspondence between the energy gain associated with forming the superconducting ground state, and the dramatic changes seen in angle resolved photoemission spectra. Some implications this observation has are offered.

Photovoltaic manufacturing cost and throughput improvements for thin-film CIGS-based modules: Phase 1 technical report, July 1998--July 1999
The primary objectives of the Global Solar Energy (GSE) Photovoltaic Manufacturing Technology (PVMaT) subcontract are directed toward reducing cost and expanding the production rate of thin-film CuInGaSe{sub 2} (CIGS)-based PV modules on flexible substrates. Improvements will be implemented in monolithic integration, CIGS deposition, contact deposition, and in-situ CIGS control and monitoring. In Phase 1, GSE has successfully attacked many of the highest risk aspects of each task. All-laser, selective scribing processes for CIGS have been developed, and many end-of-contract goals for scribing speed have been exceeded in the first year. High-speed ink-jet deposition of insulating material in the scribes now appears to be a viable technique, again exceeding some end-of-contract goals in the first year. Absorber deposition of CIGS was reduced corresponding to throughput speeds of up to 24-in/min, also exceeding an end-of-contract goal. Alternate back-contact materials have been identified that show potential as candidates for replacement of higher-cost molybdenum, and a novel, real-time monitoring technique (parallel-detector spectroscopic ellipsometry) has shown remarkable sensitivity to relevant properties of the CIGS absorber layer for use as a diagnostic tool. Currently, one of the bilayers has been baselined by GSE for flexible CIGS on polymeric substrates. Resultant back-contacts meet sheet-resistance goals and exhibit …

Pinch me - I'm fusing! Fusion Power - what is it? What is a z pinch? And why are z-pinches a promising fusion power technology?
The process of combining nuclei (the protons and neutrons inside an atomic nucleus) together with a release of kinetic energy is called fusion. This process powers the Sun, it contributes to the world stockpile of weapons of mass destruction and may one day generate safe, clean electrical power. Understanding the intricacies of fusion power, promised for 50 years, is sometimes difficult because there are a number of ways of doing it. There is hot fusion, cold fusion and con-fusion. Hot fusion is what powers suns through the conversion of mass energy to kinetic energy. Cold fusion generates con-fusion and nobody really knows what it is. Even so, no one is generating electrical power for you and me with either method. In this article the author points out some basic features of the mainstream approaches taken to hot fusion power, as well as describe why z pinches are worth pursuing as a driver for a power reactor and how it may one day generate electrical power for mankind.
