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.
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.
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, SCKoCEN, 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 of nuclear materials, i.e. the interaction between these
materials and their environments, is a major issue for plant safety
as well as for operation and economic competitiveness.
Understanding these corrosion mechanisms, the systems and materials
they affect, and the methods to accurately measure their incidence
is of critical importance to the nuclear industry. Combining
assessment techniques and analytical models into this understanding
allows operators to predict the service life of corrosion-affected
nuclear plant materials, and to apply the most appropriate
maintenance and mitigation options to ensure safe long term
operation. This book critically reviews the fundamental corrosion
mechanisms that affect nuclear power plants and facilities. Initial
sections introduce the complex field of nuclear corrosion science,
with detailed chapters on the different types of both aqueous and
non aqueous corrosion mechanisms and the nuclear materials
susceptible to attack from them. This is complemented by reviews of
monitoring and control methodologies, as well as modelling and
lifetime prediction approaches. Given that corrosion is an applied
science, the final sections review corrosion issues across the
range of current and next-generation nuclear reactors, and across
such nuclear applications as fuel reprocessing facilities,
radioactive waste storage and geological disposal systems. With its
distinguished editor and international team of expert contributors,
Nuclear corrosion science and engineering is an invaluable
reference for nuclear metallurgists, materials scientists and
engineers, as well as nuclear facility operators, regulators and
consultants, and researchers and academics in this field.
Stress Corrosion Cracking of Nickel Based Alloys in Water-Cooled
Nuclear Reactors: The Coriou Effect presents the latest information
on brittle failure of metals in corrosive chemical environments
under the influence of tensile stresses. Nickel alloys are more
resistant to SCC as well as high temperatures and have been widely
used in more challenging environments such as nuclear power plants.
However, these alloys can suffer SCC under certain conditions,
resulting in component failure. A key figure in understanding the
mechanisms of SCC in nickel alloys in water-cooled nuclear reactors
is Henri Coriou of the CEA, France's leading center for nuclear
research. This book assesses his work in the context of the latest
research on SCC in nickel alloys in nuclear power plants.
