Structural Alloys For Power Plants from the Author: A. Shirzadi. Current fleets of conventional and nuclear power plants face increasing hostile environmental conditions due to increasingly high temperature operation for improved capacity and efficiency, and the need for long term service. Additional challenges are presented by the requirement to cycle plants to meet peak-load operation. This book presents a comprehensive review of structural materials in conventional and nuclear energy applications. Opening chapters address operational challenges and structural alloy requirements in different types of power plants. The following sections review power plant structural alloys and methods to mitigate critical materials degradation in power plants.

Materials For Ultra Supercritical And Advanced Ultra Supercritical Power Plants from the Author: Augusto Di Gianfrancesco. Materials for Ultra-Supercritical and Advanced Ultra-Supercritical Power Plants provides researchers in academia and industry with an essential overview of the stronger high-temperature materials required for key process components, such as membrane wall tubes, high-pressure steam piping and headers, superheater tubes, forged rotors, cast components, and bolting and blading for steam turbines in USC power plants. Advanced materials for future advanced ultra-supercritical power plants, such as superalloys, new martensitic and austenitic steels, are also addressed. Chapters on international research directions complete the volume. The transition from conventional subcritical to supercritical thermal power plants greatly increased power generation efficiency. Now the introductions of the ultra-supercritical (USC) and, in the near future, advanced ultra-supercritical (A-USC) designs are further efforts to reduce fossil fuel consumption in power plants and the associated carbon dioxide emissions. The higher operating temperatures and pressures found in these new plant types, however, necessitate the use of advanced materials. Provides researchers in academia and industry with an authoritative and systematic overview of the stronger high-temperature materials required for both ultra-supercritical and advanced ultra-supercritical power plants Covers materials for critical components in ultra-supercritical power plants, such as boilers, rotors, and turbine blades Addresses advanced materials for future advanced ultra-supercritical power plants, such as superalloys, new martensitic and austenitic steels Includes chapters on technologies for welding technologies

Fundamental Aspects Of Structural Alloy Design from the Author: Robert Jaffee. FUNDAMENTAL ASPECTS OF STRUCTURAL ALLOY DESIGN is the proceedings of the tenth Battelle Colloquium in the Materials Sciences, held in Seattle, Washington, and Harrison Hot Springs, B.C., September 15-19, 1975. The theme of the conference was the emerging science of alloy design. Although the relationships of properties of alloys to their composition and structure have long been a dominant theme in physical metallurgy, it is only recently that metallurgists have turned their attention from the analytical, post hoc study of the structure-property relationship to the synthesis approach of alloy design. As usual in the Battelle colloquia, the first day started with a group of introductory lectures presented by leaders in the field, each emphasizing his personal approach to the problem. This provided a historical perspective for the colloquium. These papers, together with the banquet address of Professor J. R. Low, Jr., who was honored at the colloquium, comprise the introductory section of these proceedings. Alloy design is generally specific to a given application. Thus, the needs in alloy design in a number of important applications, gas turbines, electrical-power-generation equipment, airframes, pressure vessels, and nuclear applications were presented in a group of papers. An agenda discus sion on "Needs in Alloy Design" followed. These papers give the external constraints on alloy design applications, and criteria for mechanical, physical, and chemical properties for which the alloys must be designed.

Liquid Metal Engineering Aspects Of A Commercial Sized Power Plant Based On The Hylife Converter Concept from the Author: . A study of a commercial fusion plant based on the High Yield Lithium Injection Fusion Energy (HYLIFE) converter has been performed. A net efficiency of 33.3% was derived for a plant using 2-1/4 Cr - 1 Mo ferritic steel as structural alloy. Use of a thick lithium fall to protect structural materials from the deleterious effects of pellet thermonuclear burn allows the structure to last the life of the plant without replacement. Both mechanical pumps and EM pumps are analyzed for this application. The power requirement for the lithium fall mechanical pumps is approx. 20 MWe. This is a relatively insignificant 1.6% of the gross electrical power output of the plant of approx. 1250 MWe. An EM pump has a greater electrical requirement but the lesser head (NPSH) requirement of an EM pump appears to be a marked advantage since this affects the size of the lithium inventory. The preferred tritium separation method appears to be that developed by Argonne National Laboratory which involves mixing lithium into an immiscible liquid having a greater affinity for hydrogen isotopes, with subsequent electrolytic separation. The immiscible liquid under consideration is a lithium bromide-lithium fluoride-lithium chloride mixture.

Water Chemistry And Corrosion Of Nuclear Power Plant Structural Materials from the Author: V. G. Kritsky. This book addresses structural material corrosion in coolant circuits, simulation of erosion corrosion of carbon and low-alloy steels, and simulation of stress corrosion. It also discusses corrosion of copper alloys, zirconium corrosion, optimization of water chemistry at operating nuclear power plants, coolant tendency to deposit hardness salts on heat-transfer surfaces, and inspection of metallic components. In addition, there are two appendixes, the first showing the chemical composition of steels, the second discussing solubility of iron, cobalt, zinc and copper corrosion products under conditions simulating power unit water chemistry.

Materials For Nuclear Plants from the Author: Wolfgang Hoffelner. The clamor for non-carbon dioxide emitting energy production has directly impacted on the development of nuclear energy. As new nuclear plants are built, plans and designs are continually being developed to manage the range of challenging requirement and problems that nuclear plants face especially when managing the greatly increased operating temperatures, irradiation doses and extended design life spans. Materials for Nuclear Plants: From Safe Design to Residual Life Assessments provides a comprehensive treatment of the structural materials for nuclear power plants with emphasis on advanced design concepts. Materials for Nuclear Plants: From Safe Design to Residual Life Assessments approaches structural materials with a systemic approach. Important components and materials currently in use as well as those which can be considered in future designs are detailed, whilst the damage mechanisms responsible for plant ageing are discussed and explained. Methodologies for materials characterization, materials modeling and advanced materials testing will be described including design code considerations and non-destructive evaluation concepts. Including models for simple system dynamic problems and knowledge of current nuclear power plants in operation, Materials for Nuclear Plants: From Safe Design to Residual Life Assessments is ideal for students studying postgraduate courses in Nuclear Engineering. Designers on courses for code development, such as ASME or ISO and nuclear authorities will also find this a useful reference.
