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.

Corrosion Modelling with Cellular Automata bridges the gap between finer scales based on atomic physics and the larger-scale based on physico-chemical properties of materials and their environments. The book describes the simulation and modeling of corrosion phenomena by cellular automata and underlines the collaborative and interdisciplinary relationships that underpin them. It explores the major achievements that have been performed to date, covers basic knowledge on cellular automata and corrosion phenomena, and includes sections on CA modeling of generalized and uniform corrosion in 2D and 3D under various conditions, including aqueous environments and high temperature processes. Finals sections present examples on the use of cellular automata for modeling localized corrosion as well as recent developments on intergranular corrosion. There is also a review on the use of CA for modeling pitting corrosion. - Focuses on the use of cellular automata for modeling corrosion - Covers recent advances in modeling generalized corrosion with cellular automata - Illustrates how cellular automata can be used to model localized corrosion (pitting and intergranular corrosion) - Spans various length scales from atomistic to mesoscale

Corrosion Under Insulation (CUI) Guidelines: Technical Guide for Managing CUI, Third Edition, Volume 55 builds upon the success of the first two editions to provide a fully up-to-date, practical source of information on how to monitor and manage insulated systems. In the first edition of this book published in 2008, the EFC Working Parties WP13 and WP15 engaged together to provide guidelines on managing CUI with contributions from a number of European refining, petrochemical, and offshore companies. The guidelines were intended for use on all plants and installations that contain insulated vessels, piping, and equipment, and cover a risk-based inspection methodology for CUI, inspection techniques, and recommended best practices for mitigating CUI. The guidelines include design of plant and equipment, coatings and the use of thermal spray techniques, types of insulation, cladding/jacketing materials, and protection guards. Corrosion-under-insulation (CUI) refers to the external corrosion of piping and vessels that occurs underneath externally clad/jacketed insulation as a result of the penetration of water. By its very nature CUI tends to remain undetected until the insulation and cladding/jacketing is removed to allow inspection, or when leaks occur. CUI is a common problem shared by the refining, petrochemical, power, industrial, onshore and offshore industries. - Provides revised and updated technical guidance on managing CUI provided by EFC Working Parties 13 and 15 - Discusses the standard approach to risk based inspection methodology - Presents the argument that CUI is everywhere, and looks at mitigating actions that can be started from the onset - Includes a wide array of concepts of corrosion mitigation

First Published in 2017. Pipeline integrity is key to maintaining operational success, safety and security and minimising harm to the environment. Corrosion is a dominant contributory factor to failures, leaks and integrity threats in pipelines. Therefore, its optimum control within an integrity management framework is paramount for the cost-effective design of facilities and ensuring continued, uninterrupted and safe operations within the expected design life. This recommended practice (RP) is a compendium of current best practices and state-of-the-art knowledge by major operators, engineering contractors and service companies involved in hydrocarbon pro-duction and transportation. The RP incorporates some minimum operational requirements and practices to ensure that when man-aging corrosion in pipelines, fundamental principles are followed. It covers management of corrosion for pipelines carrying hydrocarbons, injection water and/or produced water from design to decommissioning. It is structured to follow the logical steps of a basic corrosion management process and makes references to relevant and available international standards and/or recommended practices. It is intended for use by personnel from the petroleum industry having knowledge of corrosion and materials. It is hoped that this RP will prove to be a key reference document for engineers, suppliers and con-tractors working in the oil and gas industry, paving the way for corrosion-free operation of pipelines with the ultimate goal of improving safety, security and minimising the impact on the environment

Biocorrosion refers to corrosion influenced by bacteria adhering to surfaces in biofilms. Biocorrosion is a major problem in areas such as cooling systems and marine structures where biofilms can develop. This book summarises key recent research in this subject. Part one looks at theories of biocorrosion and measurement techniques. Part two discusses how bacteria and biofilms result in biocorrosion. The final part of the book includes case studies of biocorrosion in areas as diverse as buildings, fuels, marine environments and cooling systems. - Provides a detailed overview of biocorrosion and the different scientific and/or industrial problems related to microbially induced corrosion - Introduces a variety of investigative techniques and methodologies that are employed in diagnosing and evaluating microbially induced corrosion - Includes case studies on: biodeterioration of building materials; biocorrosion issues associated with diesel and biofuels; marine biocorrosion; corrosion of open recirculating cooling water systems and cooling system components; the effect of H2S on steel corrosion

The guidelines also include case studies. The original document first published in 2008 was very successful and provided an important resource in the continuing battle to mitigate CUI. Many members of the EFC corrosion community requested an update and this has taken between 18-24 months to do so. Hopefully this revised document will continue to serve the community providing a practical source of information on how to monitor and manage insulated systems.
