This book was released on 2008 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report extends the application of on-line monitoring to equipment and process condition monitoring, encompassing an array of technologies including vibration monitoring, acoustic monitoring, loose parts monitoring, motor current signature analysis and noise diagnostics, as well as vibration analysis of the reactor core and the primary circuit. Furthermore, this report includes the application of modeling technologies for equipment and process condition monitoring. A majority of these technologies depend on existing data from existing sensors and first principles models to estimate equipment and process behavior using empirical and physical modeling techniques. In doing so, pattern recognition tools such as neural networks, fuzzy classification of data, multivariate state estimation and other means are used. These means are described in the report, and examples of their application and implementation are provided. The benefits of OLM for performance verification of process instruments were described in the first report and included such advantages as the ability to extend the calibration interval of pressure, level and flow transmitters, detection of blockages, voids and leaks in pressure sensing lines, detection of degradation of the dynamic response of process instruments, and the like. Examples of benefits of OLM for condition monitoring include: (1) the ability to determine the onset of failure of pumps, valves, motors and reactor vessel components; (2) residual life assessment of equipment; (3) equipment life extension and aging management; (4) the ability to establish objective schedules for preventive maintenance, equipment refurbishment or replacement; and (5) maintenance cost reduction, efficiency improvements, reduction of plant outages, and reduction of radiation exposure to plant personnel.--Publisher's description.

Download or read book The Potential Role of New Technology for Enhanced Safety and Performance of Nuclear Power Plants Through Improved Service Maintenance written by Ted Glen Achorn and published by . This book was released on 1991 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Refinements in the safety and performance of nuclear power plants must be made to maintain public confidence and ensure competitiveness with other power sources. The aircraft industry, US Navy, and other programs have proven many advanced service maintenance methods that may improve commercial nuclear plants. This thesis is concerned with how new technologies in sensing and monitoring can be used to reduce the potential for hardware failures. The specific components with the greatest impacts upon safety and performance were determined using historical data from the experience of the nuclear industry. Failure modes associated with selected components are used to indicate the most important monitoring needs and these requirements help focus a technology survey for potential improvements. The thesis concludes with a discussion of possible applications which may enhance monitoring needs. Proposals for focusing future research to further develop appropriate technologies are presented. Nuclear facility managers are provided a means to self-analyze the status of onsite efforts to improve vital safety and performance related equipment in this thesis. Many of the monitoring needs and potential improvements indicated have general application to most plants. The process discussed in this report can be used to further tailor technology to plant specific needs.

Available in PDF, EPUB and Kindle. Book excerpt: This guidebook provides specific advice and guidance to project management for the construction of nuclear power plants. While operating performance of nuclear power plants has been improving in recent years and has generally been comparable to or better than that of fossil fired plants in the same size ranges, performance during construction has been variable. Although additional licensing requirements, public intervention and funding problems have been blamed for most of the delays and cost increases, there is growing recognition that lack of proper project management has been a major factor.
