This is an update on EPRI research on sensors and data analytics for transmission and distribution, including field demonstrations and technical insights.
This report is an overview of energy storage technologies, applications, cost and installation estimates, and regulations and policies to encourage deployment.
Drawing from nuclear plant operating experience between 1970 and 2015, this report provides updated information on piping system failure rates and rupture frequencies for use in probabilistic risk assessments.
Through a literature review and laboratory tests, this study evaluates on-line health monitoring for electric generators, with a focus on methods involving measurements of electrical parameters.
This study used an experimental recirculating water loop to evaluate the effectiveness of a film-forming product on mitigating flow-accelerated corrosion in power plant components.
For tracking chloride and sulfate concentrations in nuclear plants, most operators sample reactor coolant or steam generator blowdown daily and analyze samples with ion chromatography instruments in a plant laboratory. As an alternative to this resource-intensive approach, EPRI examined microchip capillary electrophoresis, a new technology that can potentially be used for online monitoring of chloride and sulfate with more timely results and reduced radiation exposure. This study demonstrated the technology at a pressurized water reactor and a boiling water reactor, comparing the results to those yielded from ion chromatography.
This plume dispersal model calculates single- or multi-source impacts of primary and secondary pollutant emissions at downwind locations.
By relying on field forces rather than physical contact between surfaces to achieve high rotational speed, magnetic gears can potentially reduce the mass and cost of drive-trains for wind turbines rated above 10 megawatts, while improving efficiency and reliability. This brief report provides an overview of the technical basis, status, and potential of magnetic gearboxes for use in large-scale wind turbines.
In this report, EPRI comments on the results, strengths, and limitations of a Utrecht University study examining the relationship between amyotrophic lateral sclerosis mortality and occupational exposure to low-frequency magnetic fields and electric shocks.
This report discusses the state of knowledge and techniques for monitoring of power plant cooling water systems, including control of cooling processes and evaluation of water treatment programs.
This report discusses results of EPRI research on expected costs and performance for new and retrofit fossil-fuel power plants with carbon capture and storage. Plant types include pulverized coal, fluidized-bed combustion, integrated gasification combined cycle, and natural gas combined cycle.
With a focus on utility-scale solar plants, this paper investigates links between plant design and long-term operations and maintenance costs, such as the effects of row spacing, racking and tracking, cable management, soiling and vegetation management, data monitoring and communications set-up, and inverter selection and engineering.
