Will competition hurt electricity consumers in the Pacific Northwest
A computer model was developed at Oak Ridge National Laboratory to analyze the electricity production, costs, and prices for two geographical regions for a single year. Bulk-power trading is allowed between the two regions and market clearing prices are determined based on marginal costs. The authors used this model, ORCED, to evaluate the market price of power over the year 2000 in the Pacific Northwest and California. The authors found that, absent intervention by the regulators in the Northwest, generation prices would increase 1.1 {cents}/kWh on average, from 1.91 {cents}/kWh for the regulated price to 3.02 {cents}/kWh as the competitive price. If regulators use transition charges and price caps, then customers in the Pacific Northwest need not be penalized by the change to marginal-cost pricing. Customer responses to price changes will increase the transfer of power between regions. A gas price increase of 20%, while only raising the average-cost-based price to 1.95 {cents}/kWh, raised the marginal-cost-based price to 3.56{cents}/kWh. Reductions in hydroelectric resources also dramatically change the price and flow of power.

The greenhouse of the future: Using a sponsored competition in a capstone course
Educational objectives of capstone courses such as critical-thinking and problem-solving skills are among the most cited needs in curriculum revitalization efforts. Sponsored competitions present an important vehicle for achieving these educational objectives. Opportunities such as the Greenhouse of the Future Competition provide students a diverse range of critical experiences not easily simulated in traditional classroom settings. The objective of the competition was to provide an opportunity for US university students to conceptualize, design, integrate, fabricate, and demonstrate innovative greenhouse or controlled environment ideas. The students achieved a great sense of accomplishment and satisfaction by converting their ideas into proposals, developing proposals into experiments, tracking the data generated by the experiments and translating that data into a meaningful communication locally and to the scientific community at large. Most of these important learning experiences would have remained as components of the project even if the team had not advanced as the winning entry.

Possible effects of competition on electricity consumers in the Pacific Northwest
In part, the impetus for restructuring the U.S. electricity industry stems from the large regional disparities in electricity prices. Indeed, industry reforms are moving most rapidly in high-cost states, such as California and those in the Northeast. Legislators, regulators, and many others in states that enjoy low electricity prices, on the other hand, ask whether increased competition will benefit consumers in their states. This report quantifies the effects of increased competition on electricity consumers and producers in two regions, the Pacific Northwest and California. California`s generating costs are roughly double those of the Northwest. We use a new strategic-planning model called Oak Ridge Competitive Electricity Dispatch (ORCED) to conduct these analyses. Specifically, we analyzed four cases: a pre-competition base case intended to represent conditions as they might exist under current regulation in the year 2000, a post-competition case in which customer loads and load shapes respond to real-time electricity pricing, a sensitivity case in which natural-gas prices are 20% higher than in the base case, and a sensitivity case in which the hydroelectric output in the Northwest is 20% less than in the base case. The ORCED analyses suggest that, absent regulatory intervention, retail competition would increase profits for producers …

The Spectroscopy of {sup 183}Tl: An Extreme Case of Prolate-Oblate Shape-Competition
The yrast sequence in {sup 183}Tl has been studied for the first time in recoil-mass and decay tagged gamma-ray spectroscopic measurements. A rotational-like cascade of seven transitions is observed down to the bandhead with spin 13/2+. In contrast to adjacent nuclei, links from the yrast band to a lower lying weakly deformed (oblate) structure are not observed. It appears that the prolate energy minimum in {sup 183}Tl drops significantly compared to {sup 185}Tl and minimizes below the neutron i13/2 midshell (n <= 102). Possibilities for the decay out of the band in {sup 183}Tl are discussed.

From monopoly to markets: Milestones along the road. Occasional paper {number_sign}25
This report analyzes developments in the electric utility industry using the tools of transaction cost economics. During the last thirty years, the tools of economic analysis have been substantially expanded--notably, Oliver Williamson, building on the insights of Coase and others, has made significant contributions through his work in developing the new institutional economics, of which transaction cost economics reasoning plays a major role. Because of the relevance of the new institutional economics to public utilities and public utility regulation, the theoretical insights of the new institutional economics have been applied to many aspects of public utility industry structure, governance, and regulation. The contributions of Joskow and Schmalensee are most notable, but many other economists have made theoretical and empirical contributions. These insights are very applicable to the issues that policymakers and regulators are likely to address as electric restructuring progresses. The goal of this report is to synthesize the theoretical work on the new institutional economics with the recent developments in the electric utility industry--most notably, the rapid trend toward competition in electric generation, both in the US and abroad. Transaction-cost-economics reasoning provides an analytical structure for understanding the implications of asset specificity, asymmetric and imperfect information, reputation effects, ex …

Clean cast steel technology. Final report
This report documents the results obtained from the Clean Cast Steel Technology Program financially supported by the DOE Metal Casting Competitiveness Research Program and industry. The primary objective of this program is to develop technology for delivering steel free of oxide macroinclusions to mold cavities. The overall objective is to improve the quality of cast steel by developing and demonstrating the technology for substantially reducing surface and sub-surface oxide inclusions. Two approaches are discussed here. A total of 23 castings were produced by submerge pouring along with sixty conventionally poured castings. The submerged poured castings contained, on average, 96% fewer observable surface inclusions (11.9 vs 0.4) compared to the conventionally poured cast parts. The variation in the population of surface inclusions also decreased by 88% from 5.5 to 0.7. The machinability of the casting was also improved by submerged pouring. The submerge poured castings required fewer cutting tool changes and less operator intervention during machining. Subsequent to these trials, the foundry has decided to purchase more shrouds for continued experimentation on other problem castings where submerge pouring is possible. An examination of melting and pouring practices in four foundries has been carried out. Three of the four foundries showed significant …

Evidence of cost growth under cost-plus and fixed-price contracting
As defined by the US Department of Energy (DOE), privatization refers to a shifting of responsibilities for the completion of projects from a cost-plus Management and Operations (M and O) contract, to incentive-based contracts with the private sector. DOE`s new vision is to arrange cleanup work around incentives-based contracts, which are won via competitive bidding. Competition in awarding cleanup contracts can make use of market incentives to lower project costs and reduce slippage time. Fixed-price contracts encourage contractors to minimize schedule delays and cost overruns once the scope of a project has been negotiated. Conversely, cost-plus contracting offers weak incentives for contractors to select cost-minimizing production and management approaches. Because privatization explicitly allocates more risk to the contractor, it forces the government to better define its goals and methods. This study summarizes actual cost experiences with government contracts performed under cost-plus and fixed-price incentive structures at all levels of government. The first section provides some background on the problem of making contractor activity more cost-efficient. Following this are sections on the measurement of performance and the costs of projects, limitations on measurement, and findings of similar studies. The study concludes with appendices discussing the details of the performance measurement methodology …

Rapid response manufacturing (RRM). Final CRADA report
US industry is fighting to maintain its competitive edge in the global market place. Markets fluctuate rapidly. Companies have to be able to respond quickly with improved, high quality, cost efficient products. Because companies and their suppliers are geographically distributed, rapid product realization is dependent on the development of a secure integrated concurrent engineering environment operating across multiple business entities. The way products are developed and brought to market can be improved and made more efficient through the proper incorporation of emerging technologies implemented in a secure environment. This documents the work done under this CRADA to develop capabilities, which permit the effective application, incorporation, and use of advanced technologies in a secure environment to facilitate the product realization process. Lockheed Martin Energy Systems (LMES), through a CRADA with the National Center for Manufacturing Sciences (NCMS), worked within a consortium of major industrial firms--Ford, General Motors, Texas Instruments, United Technologies, and Eastman Kodak--and several small suppliers of advanced manufacturing technology--MacNeal-Schwendler Corp., Teknowledge Corp., Cimplex Corp., Concentra, Spatial Technology, and Structural Dynamics Research Corp. (SDRC)--to create infrastructure to support the development and implementation of secure engineering environments for Rapid Response Manufacturing. The major accomplishment achieved under this CRADA was the demonstration …

The Effects of Video-Computerized Feedback on Competitive State Anxiety, Self-Efficacy, Effort, and Baseball Hitting-Task Performance
This study examined the effects of frame-by-frame video-computerized feedback on competitive state anxiety, self-efficacy, effort, and baseball performance of high school players. Players were randomly assigned to one of three feedback conditions: (a) Hitting score, (b) Hitting score and frame-by-frame analysis of a mechanically correct swing, (c) Hitting score and frame-by-frame analysis of participant's swing and a mechanically correct swing. Once per week for six weeks, the players completed three questionnaires: (a) Hitting Self-Efficacy Scale, (b) Competitive State Anxiety Inventory-2C, and (c) Performance Effort Scale, and performed a hitting task. Results of the 3 (Group) x 6 (Trials) ANOVAs revealed no significant effects. This study does not support previous confidence-baseball hitting research.

Electricity Restructuring Background: The Public Utility Regulatory Policies Act of 1978 and the Energy Policy Act of 1992
The Energy Policy Act of 1992 (EPACT) increased competition in the electric generating sector by creating new entities that can generate and sell electricity at wholesale without being regulated as utilities under PUHCA. PURPA began to shift more regulatory responsibilities to the federal government, and EPACT continued that shift away from the states by creating new options for utilities and regulators to meet electricity demand.

Electricity Restructuring: Comparison of S.1401, H.R. 655, H.R. 1230, S. 722, H.R. 1960, and S. 2287
Once considered the nation's most regulated industry, the electric utility industry is evolving into a more competitive environment. At the current time, the focus of this development is the generating sector, where the advent of new generating technologies, such as gas-fired combined cycle, has lowered both entry barriers to competitors of traditional utilities and lowered the marginal costs of those competitors below those of some traditional utilities. This technological advance has been combined with legislative initiatives, such as the Energy Policy Act of 1992 (EPACT), to encourage the introduction of competitive forces into the electric generating sector. The questions now are whether further legislative action is desirable to encourage competition in the electric utility sector and how the transition between a comprehensive regulatory regime to a more competitive electric utility sector can be made with the least amount of economic and service disruption.

Permanganate treatment of DnAPLs in reactive barriers and source zone flooding schemes. 1998 annual progress report
'The goals of this study are: (1) to elucidate the basic mechanisms by which potassium permanganate oxidizes common chlorinated solvents, various constituents in aqueous solution, and porous-medium solids, and (2) to assess the potential for chemical oxidation by potassium permanganate to serve as a remedial scheme involving either source zone flooding or reactive barriers. The combined theoretical and experimental study is designed to contribute fundamental knowledge about reaction pathways, reaction rates, specific intermediates formed, and controls on reaction processes. The specific objectives of this study are: (1) to describe through batch experiments the kinetics and mechanisms by which potassium permanganate oxidizes dissolved tetrachloroethene (PCE), trichloroethene (TCE), and dichloroethene (DCE), (2) to examine using column studies the nature and kinetics of reactions between potassium permanganate, residual DNAPLs (PCE, TCE, and DCE) and porous medium solids, (3) to represent the process understanding in flow and transport models that demonstrate the potential applicability of the approach, and (4) to apply the resulting computer code in the development of appropriate field tests for assessing the approach. Approaching the end of Year 2 of this 3-Year project, the authors can report significant progress in meeting the objectives of the study. Through a series of batch …

Improving energy efficiency: Strategies for supporting sustained market evolution in developing and transitioning countries
This report presents a framework for considering market-oriented strategies for improving energy efficiency that recognize the conditions of developing and transitioning countries, and the need to strengthen the effectiveness of market forces in delivering greater energy efficiency. It discusses policies that build markets in general, such as economic and energy pricing reforms that encourage competition and increase incentives for market actors to improve the efficiency of their energy use, and measures that reduce the barriers to energy efficiency in specific markets such that improvement evolves in a dynamic, lasting manner. The report emphasizes how different policies and measures support one another and can create a synergy in which the whole is greater than the sum of the parts. In addressing this topic, it draws on the experience with market transformation energy efficiency programs in the US and other industrialized countries.

An MPP hydrocode to study laser-plasma interactions
Because of the increased size and power inherent in a laser-AGEX on NIF, laser-plasma interactions (LPI) observed in NOVA AGEX play an increasingly important role. The process by which filamentation and stimulated backscatter grow is complex. Furthermore, there is a competition among the instabilities so that lessening one can increase another. Therefore, simulating them is an integral part to successful experiments on NIF. In this paper, we present a massively parallel hydrocode to simulate laser-plasma interactions in NIF-relevant AGEX regimes.

Chemical speciation of strontium, americium, and curium in high level waste: Predictive modeling of phase partitioning during tank processing. 1998 annual progress report
'In this research program, Pacific Northwest National Laboratory (PNNL) and Florida State University (FSU) are investigating the speciation of Sr and Am/Cm in the presence of selected organic chelating agents (ethylenediaminetetraacetic acid (EDTA), N-(2-hydroxyethyl)ethylenediaminetriacetic acid (HEDTA), nitrilotriacetic acid (NTA), and iminodiacetic acid (IDA)) over ranges of hydroxide, carbonate, ionic strength, and competing metal ion concentrations present in high level waste tanks. The fundamental understanding of chemical speciation reactions gained from these studies is also used to propose methodologies for removal of Sr and Am/Cm from organic chelates present in high level tank waste, via competition, displacement or other reactions, without the need for the development of costly and potentially hazardous organic destruction technologies.'
