Available in PDF, EPUB and Kindle. Book excerpt: Recent inspections have indicated that carbon steel outlet feeder pipes in some candu reactors are experiencing wall loss near the exit from the reactor core. this phenomenon is not observed in inlet feeder pipes. examination of a sample of pipe removed from a candu 6 reactor has indicated that the mechanism causing the wall loss is flow-accelerated corrosion (fac), at rates higher than expected, but two orders of magnitude lower than those typically observed in secondary circuits of nuclear and conventional power plants. although the candu reactor outlet feeder operating temperatures and the use of lioh at a high ph should have ensured low corrosion rates, use of sa 106 grade b carbon steel with a low chromium content resulted in some susceptibility to fac. the main parameter influencing the rate of wall loss is the coolant velocity, with the bend angle playing a secondary role. a solubility-based mathematical model describing the effects of water chemistry and coolant hydrodynamics on the rate of fac has been developed and has been recently improved by the empirical incorporation of the effect of electrochemical potential on the solubility of magnetite. experiment and theory have indicated that the corrosion rates are lower at lower ph values within the permissible operating range. experiments are being conducted to obtain more information on the effects of water chemistry and material composition on fac. current results support the predicted effects of ph and carbon steel chromium content on the fac rate. remedial measures implemented include operation of existing reactors at the lower end of the specified ph range and the specification of a minimum of 0.20 wt% cr in the carbon steel of feeder pipes of future candu reactors.

Download or read book Surface Wear written by R. Chattopadhyay and published by ASM International. This book was released on 2001-01-01 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation Describes the surface properties controlling the wear processes in different environments, and presents techniques for reducing specific type of wear through modification of surface properties. The author characterizes the energy, morphology, and composition of surfaces, then identifies the mechanisms of wear caused by adhesion, abrasion, erosion, corrosion, and heat. The main section of the book discusses the various surface protection technologies: strain hardening, thermally assisted diffusion processes, hardening by thermal treatment, thin film coatings, and thick film overlays. The final chapters address metal, plastic and ceramic composites that resist wear, and provide a wear diagnosis methodology. Annotation copyrighted by Book News Inc., Portland, OR
