This feasibility study examines reliability centered maintenance (RCM) as it applies to Bonneville Power Administrations (BPA) substation maintenance program. Reliability techniques are examined in evaluated. Existing BPA equipment maintenance procedures are documented. Equipment failure history is considered. Economic impacts are estimated. Various equipment instrumentation methods are reviewed. Based on this analysis a prototype system is proposed. The prototype will be implemented in two phases. Phase 1 is to be completed in 1992, it includes instrumenting one power transformer and one oil circuit breaker. Software development will focus on displaying data. Phase 2 is to be completed the following year. The remaining transformers and breakers will be instrumented during the second phase. Software development will focus on predictive maintenance techniques and maintenance decision support.

The objective for this experimental work was to examine the reaction mechanisms, half-collision dynamics, and other optically induced chemical effects, that are operable on a well characterized single-crystal semiconductor surface. Of particular interest were reactions induced by charge transfer from the semiconductor surface including hot carrier and thermalized carrier processes. The primary technique to measure the desorbed fragment translational energies was time-of-flight mass-spectroscopy, used in conjunction with a pulsed tunable laser source. The work was carried out in ultrahigh vacuum, thus other surface spectroscopies such as temperature-programmed desorption, (TPD), (LEED), etc. were used as needed. In the project, the photoreactions of several halogen-containing molecules on GaAs(110) surfaces have been investigated. The studies have made the first observations of several new photochemical processes on uhv prepared surfaces including intermolecular charge transfer; desorption by thermal-carrier-induced reactions (including the measurement of coverage-dependent changes in the translational energies of the desorbed products); interferometric oscillation of photoinduced reactions; and self-quenching of thermal carrier reactions on surfaces.

The January 1992 quarterly progress report discusses a two-dimensional finite element analysis (FEA) of the proposed retrofit MHD coil. The superconducting Cable-in-Conduit Conductor (CICC) winding pack has a smooth, semi-elliptical cross section and is supported by a similarly shaped strap which resists the electromagnetic forces tending to separate the coils on each side of the channel. The coils are designed to produce a peak on-axis field of 4.5 tesla with a nominal current density of 13.05{times}10{sup 6} A/m{sup 2}. A sketch of the magnet system and structure is shown in Fig. 1.0-1. The objective of this analysis is to quantify the highly 3-D characteristics of the proposed superconductivity magnet system, and develop an appropriate support concept. A fully paramatized 3-D finite element model of the coil and structure is developed as a means of obtaining the field and stress solutions. The flexibility of FEA and a model built using design parameters allows variations in the coil end turn bend radius, strap thickness, support details and positions to be studied. The preliminary results show the calculated stresses as a result of this iterative design process.

This document is an addendum to ``Tritium in the Savannah River Site Environment,`` WSRC-RP90-424- 1, released in May of 1991. The purpose of this report is to update the information found in WSRC-RP-90-424-1 for the four year period 1987--1990. Some data has also been included from 1991. The report includes summaries of atmospheric and aqueous monitoring of tritium and estimates of the dose to the population surrounding the Savannah River Site.

In January 1990, the Department of Energy initiated this project with the objective to develop the technology for general purpose, portable gamma ray imaging cameras useful to the nuclear industry. The ultimate goal of this R&D initiative is to develop the analog to the color television camera where the camera would respond to gamma rays instead of visible photons. The two-dimensional real-time image would be displayed would indicate the geometric location of the radiation relative to the camera`s orientation, while the brightness and ``color`` would indicate the intensity and energy of the radiation (and hence identify the emitting isotope). There is a strong motivation for developing such a device for applications within the nuclear industry, for both high- and low-level waste repositories, for environmental restoration problems, and for space and fusion applications. At present, there are no general purpose radiation cameras capable of producing spectral images for such practical applications. At the time of this writing, work on this project has been underway for almost 18 months. Substantial progress has been made in the project`s two primary areas: mechanically-collimated (MCC) and electronically-collimated camera (ECC) designs. We present developments covering the mechanically-collimated design, and then discuss the efforts on the electronically-collimated …
