The objective of this study was to examine the relative importance of pressure changes as a source of turbine-passage injury and mortality. Specific tests were designed to quantify the response of fish to rapid pressure changes typical of turbine passage, with and without the complication of the fish being acclimated to gas supersaturated water. We investigated the responses of rainbow trout (Oncorhynchus mykiss), chinook salmon (O. tshawytscha), and bluegill sunfish (Lepomis macrochirus) to these two stresses, both singly and in combination.

Non-destructive testing is a key component of optimized plant inspection and maintenance programs. Risk based inspection, condition based maintenance and reliability centered maintenance systems all require detection, location and sizing of defects or flaws by non-destructive methods. Internal damage of geothermal piping by corrosion and erosion-corrosion is an ongoing problem requiring inspection and subsequent maintenance decisions to ensure safe and reliable performance. Conventional manual ultrasonic testing to determine remaining wall thickness has major limitations, particularly when damage is of a random and localized nature. Therefore, it is necessary to explore alternative non-destructive methods that offer potential benefits in terms of accurate quantification of size, shape and location of damage, probability of detection, ability to use on-line over long ranges, and economics. A review of non-destructive methods and their applicability to geothermal piping was performed. Based on this, ongoing research will concentrate on long range guided wave and dynamic methods.

This document described a laboratory study designed to determine whether mercury is, in fact, reduced by bisulfite ion and ammonia and, if so, whether the reduced mercury is volatilized at the boiling point of water. The primary conclusions resulting from this study are that both bisulfite ion and ammonia are capable of reducing mercury in solution and that, when reduced, the mercury will all be volatilized and carried into the distillate.

An artificial neural network (ANN) method is developed for treating the spatial variable of the one-group slab-geometry discrete ordinates (S{sub N}) equations in a homogeneous medium with linearly anisotropic scattering. This ANN method takes advantage of the function approximation capability of multilayer ANNs. The discrete ordinates angular flux is approximated by a multilayer ANN with a single input representing the spatial variable x and N outputs representing the angular flux in each of the discrete ordinates angular directions. A global objective function is formulated which measures how accurately the output of the ANN approximates the solution of the discrete ordinates equations and boundary conditions at specified spatial points. Minimization of this objective function determines the appropriate values for the parameters of the ANN. Numerical results are presented demonstrating the accuracy of the method for both fixed source and incident angular flux problems.

The main goal of this study is to ensure sustainable management of wetland forests in the southeastern United States. The study is projected to measure soil, hydrology, and forest responses to several management scenarios across a complete forest cycle. From August 1997 to August 2000 the study has received funding as one of the Agenda 2020 projects, from the U.S. Department of Energy (Cooperative Agreement Number DE-FC07-97ID13551), the National Council of the Paper Industry for Air and Stream Improvement, and Westvac Corporation. Quarterly progress reports were submitted regularly to the Department and all project participants. This final report summarizes the project results and progress achieved during this 3-year period. Over the past three years all research objectives planned for this project were completed.

PIANO is a dynamic, subcritical, zero-yield experiment intended for execution in the U1a.102C drift of the U1a complex at the Nevada Test Site (NTS) (Figure 1). The data from the PIANO experiment will be used in the Stockpile Stewardship Program to assess the aging of nuclear weapon components and to better model the long-term performance of the weapons in the enduring stockpile. The PIANO experiment is composed of one experimental package. The experimental package will have high explosive (HE) and special nuclear material (SNM) in a subcritical assembly. The containment plan for the PIANO series of experiments utilizes a two-containment-vessel concept. The first Containment vessel is formed by the primary containment barrier that seals the U1a.102C drift. The second containment vessel is formed by the secondary containment barrier in the U100 drift. The PIANO experiment is the final experiment to be conducted in the U1a.102C alcove. It will be an ''open'' experiment--meaning that PIANO will not utilize a confinement vessel as the previous OBOE experiments in this alcove did. We expect that the SNM from the PIANO experiment will be fully contained within the first containment vessel.

On March 19, 2001, the Senate began consideration of the McCain-Feingold campaign finance reform bill. The bill–S. 27 (Bipartisan Campaign Reform Act of 2001)–was introduced on January 22, 2001 by Senators McCain, Feingold, Cochran et al. It features a ban on the raising of soft money by national parties, a ban on the spending of soft money by state and local parties on federal election-related activities (as defined), and a disclosure requirement for electioneering messages not regulated by federal election law, along with a ban on their funding from union or for-profit corporation treasuries. Another bill receiving considerable Senate attention is S. 22 (Open and Accountable Campaign Financing Act of 2001), introduced on January 22, 2001 by Senators Hagel, Landrieu et al. It features limits on soft money donations to national parties, increases in hard money contribution limits, and a requirement that broadcasters make information available on groups engaging in issue advocacy. This report provides a summary and comparison of these two measures, according to various categories.

The accumulation in groundwater of products from the radioactive decay of elements naturally found in rocks offers a potential for measuring the time that the groundwater has been contact with the rock. This dating method has an advantage over using decay products from the atmosphere in that the amount of decay products increases with age rather than decreases. However, different decay products accumulate at different rates and, thus, have a different potential usefulness in age determinations. The most useful decay product is helium, produced from uranium and thorium. The use of Ar-40 produced from potassium is limited because Ar-40 is abundant in meteoric water. Neon, xenon and krypton are useful with great difficulty because they are produced in extremely small quantities. In general, the potential for error increases when a long time is required to produce a small quantity of the dating nuclide.

Defining the married couple as a single tax unit under the federal individual income tax means that some married couples pay more income tax than they would as two unmarried singles (a marriage tax penalty) while other married couples pay less income tax than they would as two unmarried singles (a marriage tax bonus).

As part of this research effort, we developed a new methodology for projecting elderly traffic crash fatalities. This methodology separates exposure to crashes from crash risk per se, and further divides exposure into two components, the number of miles driven and the likelihood of being a driver. This component structure permits conceptually different determinants of traffic fatalities to be projected separately and has thorough motivation in behavioral theory. It also permits finer targeting of particular aspects of projections that need improvement and closer linking of projections to possible policy instruments for influencing them.

Over the last several years most of the sludge and liquid from the Liquid Low-Level Waste (LLLW) tanks at ORNL has been transferred and consolidated in the Melton Valley Storage Tanks (MVST). The contents of the MVST tanks at the time the sludge samples were collected for this report included the original inventory in the MVSTs along with the sludge and liquid from the Bethel Valley Evaporator Service Tanks (BVEST), Old Hydrofracture (OHF) tanks, and most of the Gunite and Associated Tanks (GAAT). During the spring and summer of 2000 the MVST composite sludge was sampled and characterized to validate the radiochemical content and to ensure regulatory compliance. This report only discusses the analytical characterization of the sludge from the MVST waste tanks (except for W-29 and W-30). The isotopic data presented in this report supports the position that fissile isotopes of uranium ({sup 233}U and {sup 235}U) and plutonium ({sup 239}Pu and {sup 241}Pu) were ''denatured'' as required by the administrative controls stated in the ORNL LLLW waste acceptance criteria (WAC). In general, the MVST sludge was found to be hazardous by RCRA characteristics based on total analysis of chromium, mercury, and lead. Also, the alpha activity due to …
