Age related degradation effects in safety related systems of nuclear power plants should be managed to prevent safety margins from eroding below the acceptable limits provided in plant design bases. The Nuclear Plant Aging Research (NPAR) Pro- gram, conducted under the auspices of the U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research, and other related aging management programs are developing technical information on managing aging. The aging management process central to these efforts consists of three key elements: 1) selecting structures, systems, and components (SSCs) in which aging should be controlled; 2) understanding the mechanisms and rates of degradation in these SSCs; and 3) managing degradation through effective inspection, surveillance, condition monitoring, trending, record keeping, mainten- ance, refurbishment, replacement, and adjustments in the operating environment and service conditions. This document concisely reviews and integrates information developed under the NPAR Program and other aging management studies and other available information related to understanding and managing age-related degradation effects and provides specific refer- ences to more comprehensive information on the same subjects.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Letter from Dianne Monroe to Sterling Houston, prominent San Antonio playwright. She writes to congratulate him on a recent play, On the Pulse of the Morning. She shares recent updates in her life, including a book she co-wrote titled Scattered Children, and hopes that the two can get together again. A second letter written by Sterling is included along with an envelope, but it goes unmentioned in Dianne's letter.

Letter from Rosemary Grose to Sandy Parker concerning items deemed important for district libraries, to include in an upcoming bond proposal.

The following is a description of some studies the author made on the resonant Schottky detectors in the Tevatron. The author doubts that this document contains any information that wasn't known previously, but the hope is that this document will serve as a useful self-contained reference for users of the system.

The purely nonperturbative soft contribution to the gamma^* p -> delta⁺ transition form factors is estimated using the local quark-hadron duality approach. Our results show that the soft contribution is dominated by the magnetic transition: the ratio G^* _E Q²/ G^*_M Q² is small for all accessible Q², in contrast to pQCD expectations that G^*_E (Q²) -> -G^*_M (Q²). We also found that the soft contribution to the magnetic form factor is large enough to explain the magnitude of existing experimental data.

A number of current and prospective power plant concepts were investigated to evaluate their potential to serve as the basis of the next generation geothermal power plant (NGGPP). The NGGPP has been envisaged as a power plant that would be more cost competitive (than current geothermal power plants) with fossil fuel power plants, would efficiently use resources and mitigate the risk of reservoir under-performance, and minimize or eliminate emission of pollutants and consumption of surface and ground water. Power plant concepts were analyzed using resource characteristics at ten different geothermal sites located in the western United States. Concepts were developed into viable power plant processes, capital costs were estimated and levelized busbar costs determined. Thus, the study results should be considered as useful indicators of the commercial viability of the various power plants concepts that were investigated. Broadly, the different power plant concepts that were analyzed in this study fall into the following categories: commercial binary and flash plants, advanced binary plants, advanced flash plants, flash/binary hybrid plants, and fossil/geothed hybrid plants. Commercial binary plants were evaluated using commercial isobutane as a working fluid; both air-cooling and water-cooling were considered. Advanced binary concepts included cycles using synchronous turbine-generators, cycles with …

This document consists of two reports contributed to the XXIV International Cosmic Ray Conference (Rome, Italy, August 28--September 8, 1995) from the SuperKamiokande Collaboration: one on the SuperKamiokande outer data acquisition system, and one on preliminary results from muon/electron identification tests at KEK of IMB3-detector phototubes and electronics.

This report describes efforts to identify the metabolic pathways of heterocyclic amines in animals and humans. These heterocyclic amines are potent mutagens when foods derived from muscle and other protein sources are cooked. Attempts have been made to study the effects of these toxic compounds on DNA. Attention is focused on the potential cancer risks associated with their intake as food.

This report is quarterly progress report on the Los Alamos National Laboratory Science Education Programs. Included in the report are dicussions on teacher and faculty enhancement, curriculum improvement, student support, educational technology, and institutional improvement.

This report describes integrated tank/heat exchanger modeling and experiments. Experiments were performed on a Rheem wrap-around 80 gallon electric hot water heater tank with the bottom heating element replaced by a 120 feet long coil of copper tubing wrapped around the outside lower half of the tank. The bottom two-thirds of the tank is heated by hot antifreeze circulating from the solar collector through the copper coil. Results are discussed.

Crystalline calcium thiogallate with a cerium dopant has been deposited by metal-organic chemical vapor deposition (MOCVD) at temperatures below 600{degrees}C on a low cost glass substrate. An EL luminance of 1.05 fL was observed 40 volts above threshold at 60 Hz. This is more than an order of magnitude improvement over earlier crystalline-as-deposited thiogallate materials. These results pave the way for the use of MOCVD as a potential method for processing full color thin-film electroluminescent (TFEL) flat panel displays. The formation of the CaGa{sub 2}S{sub 4}:Ce phosphor requires precise control over a number of deposition parameters including flow rates, substrate temperature, and reactor pressure. The influence of these parameters will be discussed in terms of structure, uniformity, and TFEL device performance.

The properties and performance of a ceramic component is determined by a combination of the materials from which it was fabricated and how it was processed. Most ceramic components are manufactured by dry pressing a powder/binder system in which the organic binder provides formability and green compact strength. A key step in this manufacturing process is the removal of the binder from the powder compact after pressing. The organic binder is typically removed by a thermal decomposition process in which heating rate, temperature, and time are the key process parameters. Empirical approaches are generally used to design the burnout time-temperature cycle, often resulting in excessive processing times and energy usage, and higher overall manufacturing costs. Ideally, binder burnout should be completed as quickly as possible without damaging the compact, while using a minimum of energy. Process and computational modeling offer one means to achieve this end. The objective of this study is to develop an experimentally validated computer model that can be used to better understand, control, and optimize binder burnout from green ceramic compacts.

This progress report summarizes a project to treat the diffusion and transport phenomena in multicomponent systems from an atomistic point of view mainly by means of a kinetic method based on the Cluster Variation Method (CVM)-Path Probability Method (PPM) formalism. As is well known, the CVM has established itself as one of the most systematic methods of statistical thermodynamics, and macroscopic phenomena treated by thermodynamics can thus be investigated atomistically in great detail. The author describes work in a number of different applications, summarized here by the section titles: percolation threshold in electronic conduction {beta}-alumina type solid electrolytes; mixed alkali effect; chemical diffusion problem; soft lattice gas model and rigid lattice gas model; diffusion in semiconductors; diffusion in ordered alloys; kinetics of relaxation process of hopping ionic conduction.
