Corrosion Monitoring In Nuclear Systems Efc 56

Corrosion remains one of the key issues affecting the performance and availability of nuclear power plants. Therefore, reliable in-plant corrosion monitoring methods are essential both for the future operation of existing plants and to ensure the safety of future nuclear waste disposal systems. In two parts, this book was stimulated by a workshop organised by EFC Working Party 4 on Nuclear Corrosion and the European Cooperative Group on Corrosion Monitoring of Nuclear Materials (EGC-COMON). The first part deals mainly with research into the detection of stress corrosion crack initiation in nuclear power plant environments (essentially high temperature water at around 300 °C) by various methods, particularly the electrochemical noise technique but also including the electrochemical impedance, acoustic emission and direct current potential drop methods. The second part addresses the goal to develop in-situ techniques and includes examples of the application of electrochemical corrosion potential monitoring. This book will be of particular interest to scientists and engineers concerned with the mitigation of corrosion in nuclear systems.

This book deals with detection of stress corrosion cracking (SCC) initiation in nuclear power plant environments -- essentially high-temperature water at around 300°C. It emphasises the importance of corrosion monitoring to limit corrosion in power plants and other nuclear applications.

Nuclear Corrosion: Research, Progress and Challenges, part of the “Green Book series of the EFC, builds upon the foundations of the very first book published in this series in 1989 (“Number 1 - Corrosion in the Nuclear Industry ). This newest volume provides an overview on state-of-the-art research in some of the most important areas of nuclear corrosion. Chapters covered include aging phenomena in light water reactors, reprocessing plants, nuclear waste disposal, and supercritical water and liquid metal systems. This book will be a vital resource for both researchers and engineers working within the nuclear field in both academic and industrial environments. Discusses industry related aspects of materials in nuclear power generation and how these materials react with the environment Provides comprehensive coverage of the topic as written by noted experts in the field Includes coverage of nuclear waste corrosion

First published in 1989. The EFC, incorporated in Belgium, was founded in 1955 with the purpose of promoting European co-operation in the fields of research into corrosion and corrosion prevention. In 1986 the EFC Working Party on Nuclear Corrosion was reorganised with the objective of concentrating on nine topics of relevance to the nuclear power industry. The group of experts in the Working Party. The new structure of the Working Party is based on the following topics: - Pressurised Water Reactors - Boiling Water Reactors - Fuel Elements (Cladding) - Advanced Gas Reactors - High Temperature Reactors - Liquid Metal Fast Breeders - Fusion Reactors - Reprocessing - Waste Management (Disposal). The first meeting of the Working Party following the restructuring was on the occasion of EUROCORR '87 in Frankfurt. The present volume has therefore been prepared and represents Number One in the series of EFC publications.

Stress corrosion cracking is a major problem in light water nuclear reactors, whether pressurised water reactors (PWRs) or boiling water reactors (BWRs). The nuclear industry needs to be able to predict the service life of these power plants and develop appropriate maintenance and repair practices to ensure safe long term operation. This important book sums up key recent research on corrosion in light water reactors and its practical applications. The book is divided into four parts. It begins with an overview of materials degradation due to stress corrosion, corrosion potential monitoring and passivation. Part two summarises research on susceptibility of materials to stress corrosion cracking and the ways it can be initiated. The third part of the book considers stress corrosion crack propagation processes whilst the final part includes practical case studies of corrosion in particular plants. The book reviews corrosion in a range of materials such as low alloy steels, stainless steels and nickel-based alloys. With its distinguished editor and team of contributors, Corrosion issues in light water reactors is a standard work for the nuclear industry. Summarises key recent research on corrosion in light water reactors Includes practical case studies

Engineers with an interest in the marine environment can take advantage of many years of accumulated corrosion experience in a quick and concise manner with this publication. It covers the corrosion behavior in sea water of steel, stainless steel and cast iron as well as alloys of copper, aluminum, nickel and titanium. Applications, commonly-used alloy compositions and mechanical properties are also covered for each alloy system, plus a special section is devoted to galvanic corrosion and its avoidance.

In the different disposal concepts for high-level nuclear waste, corrosion of the metallic barriers and in particular the overpack/container is a major issue. It is imperative for performance assessment to predict the lifetime of these containers. In the lifetime prediction of metallic barriers for the disposal of high level nuclear waste (HLW) or of spent fuel, the presence of (reduced) sulphur species is an issue of growing importance, as the sulphur species are involved in localised corrosion phenomena. The international workshop on Sulphur-Assisted Corrosion in Nuclear Waste Disposal Systems (SACNUC2008) aimed to provide an exchange of information on the influence of sulphur species on the corrosion of metallic barriers. This workshop was a co-organisation of the Belgian Nuclear Research Centre, SCK*CEN, and the Belgian Agency for the Management of Radioactive Waste and Enriched Fissile Materials, ONDRAF/NIRAS, under the auspices of the European Federation of Corrosion (EFC event N 311). The proceedings are divided into five chapters: Chapter 1 provides a general overview of the disposal concepts of nuclear waste and the role of corrosion. Chapter 2 explains the mechanism of sulphur-induced corrosion processes. This chapter also contains information from outside the nuclear disposal field in which sulphur is known to act as a detrimental factor (e.g. oil and gas industry). Chapter 3 addresses the role of microbial processes in sulphur-assisted corrosion. Chapter 4 covers the modelling of sulphide-assisted corrosion. Chapter 5 is devoted to a panel discussion aiming to identify open issues in the investigation of sulphur-assisted corrosion phenomena and how to incorporate these in robust lifetime prediction of metallic barriers.
