This work introduces heavy ion beam probe diagnostics and presents
an overview of its applications. The heavy ion beam probe is a
unique tool for the measurement of potential in the plasma core in
order to understand the role of the electric field in plasma
confinement, including the mechanism of transition from low to high
confinement regimes (L-H transition). This allows measurement of
the steady-state profile of the plasma potential, and its use has
been extended to include the measurement of quasi-monochromatic and
broadband oscillating components, the turbulent-particle flux and
oscillations of the electron density and poloidal magnetic field.
Special emphasis is placed on the study of Geodesic Acoustic Modes
and Alfven Eigenmodes excited by energetic particles with
experimental data sets. These experimental studies help to
understand the link between broadband turbulent physics and
quasi-coherent oscillations in devices with a rather different
magnetic configuration. The book also compares spontaneous and
biased transitions from low to high confinement regimes on both
classes of closed magnetic traps (tokamak and stellarator) and
highlights the common features in the behavior of electric
potential and turbulence of magnetized plasmas. A valuable resource
for physicists, postgraduates and students specializing in plasma
physics and controlled fusion.

This book develops an analysis of the air entrainment processes in
free-surface flows. These flows are investigated as homogeneous
mixtures with variable density. Several types of air-water
free-surface flows are studied: plunging jet flows, open channel
flows, and turbulent water jets discharging into air. Experimental
observations reported by the author confirm the concept that the
air-water mixture behaves as a homogeneous compressible fluid in
each case. This book will be of great interest to professionals
working in many fields of engineering: chemical, civil,
environmental, mechanical, mining, metallurgy, and nuclear.

This book addresses the topic of fractional-order modeling of
nuclear reactors. Approaching neutron transport in the reactor core
as anomalous diffusion, specifically subdiffusion, it starts with
the development of fractional-order neutron telegraph equations.
Using a systematic approach, the book then examines the development
and analysis of various fractional-order models representing
nuclear reactor dynamics, ultimately leading to the
fractional-order linear and nonlinear control-oriented models. The
book utilizes the mathematical tool of fractional calculus, the
calculus of derivatives and integrals with arbitrary non-integer
orders (real or complex), which has recently been found to provide
a more compact and realistic representation to the dynamics of
diverse physical systems. Including extensive simulation results
and discussing important issues related to the fractional-order
modeling of nuclear reactors, the book offers a valuable resource
for students and researchers working in the areas of
fractional-order modeling and control and nuclear reactor modeling.
This book looks at the early history of nuclear power, at what
happened next, and at its longer-term prospects. The main question
is: can nuclear power overcome the problems that have emerged? It
was once touted as the ultimate energy source, freeing mankind from
reliance on dirty, expensive fossil energy. Sixty years on, nuclear
only supplies around 11.5% of global energy and is being challenged
by cheaper energy options. While the costs of renewable sources,
like wind and solar, are falling rapidly, nuclear costs have
remained stubbornly high. Its development has also been slowed by a
range of other problems, including a spate of major accidents,
security concerns and the as yet unresolved issue of what to do
with the wastes that it produces. In response, a new generation of
nuclear reactors is being developed, many of them actually revised
versions of the ideas first looked at in the earlier phase. Will
this new generation of reactors bring nuclear energy to the
forefront of energy production in the future?

This volume is a collection of the papers presented at the
International Seminar on Advanced Nuclear Energy Systems toward
Zero Release of Radioactive Wastes, which was held in Japan in
November 2000.
Scientists and engineers working in academia, research
organizations and industry came together to discuss the role and
contributions of nuclear energy to the environmental issues in the
new millennium. It provided a forum for open discussions about the
pursuit of solutions for the reduction of nuclear wastes based on
the accelerator and fusion technologies, in addition to the
advanced fission technology to harmonize the nuclear energy systems
with the global environment. It also promoted future international
collaboration in the following research fields: the role of nuclear
energy in the new millennium; waste management; transmutation of
minor actinides and fission products; advanced fission systems,
accelerator driven systems, fusion systems, nuclear database, and
advanced nuclear fuel cycles for transmutation of wastes.
Published originally as a special issue (volume 40/3-4) of the
international journal "Progress in Nuclear Energy."
This book is a complete treatment of work done to resolve the
problems of position-, current-, and shape-control of plasma in
tokamak-type (toroidal) devices being studied as a potential means
of commercial energy production by nuclear fusion. Modelling and
control are both detailed, allowing non-expert readers to
understand the control problem. Starting from the
magneto-hydro-dynamic equations, all the steps needed for the
derivation of plasma state-space models are enumerated with
frequent recall of the basic concepts of electromagnetics. The
control problem is then described, beginning with the control of
current and position-vertical and radial-control and progressing to
the more challenging shape control. The solutions proposed vary
from simple PIDs to more sophisticated MIMO controllers. The second
edition of Magnetic Control of Tokamak Plasmas contains numerous
updates and a substantial amount of completely new material
covering areas such as: * modelling and control of resistive wall
modes-the most important non-axisimmetric mode; * the isoflux
approach for shape control; * a general approach for the control of
limiter plasmas; * the use of inner vessel coils for vertical
stabilization; and * significantly enhanced treatment of
plasma-shape control at JET, including experimental results and
introducing a method implemented for operation in the presence of
current saturations. Whenever possible, coverage of the various
topics is rounded out with experimental results obtained on
currently existing tokamaks. The book also includes a presentation
of the typical actuators and sensors used for control purposes in
tokamaks. Some mathematical details are given in the appendices for
the interested reader. The ideas formulated in this monograph will
be of great practical help to control engineers, academic
researchers and graduate students working directly with problems
related to the control of nuclear fusion. They will also stimulate
control researchers interested more generally in the advanced
applications of the discipline. Advances in Industrial Control aims
to report and encourage the transfer of technology in control
engineering. The rapid development of control technology has an
impact on all areas of the control discipline. The series offers an
opportunity for researchers to present an extended exposition of
new work in all aspects of industrial control.
This book covers the principles and practices behind the Magnetic
Confinement Fusion (MCF) approach to driven new source of energy.
All possible technical methods, including well established
theoretical research, as well as findings tested in an experimental
tokamak reactor, are examined in order to determine how to best
achieve breakeven via this pathway to plasma-driven fusion. The
author undertakes a life cycle analysis to compare and contrast the
efficiency, environmental impacts, and operating costs of
plasma-driven MCF fusion against other forms of energy generation
currently in widespread use. The associated computer code and
numerical analysis are included in the book. No prior knowledge of
MCF and no more than basic background in plasma physics is
required.
The present work focuses on the development of intensified
small-scale extraction units for spent nuclear fuel reprocessing
using advanced process engineering with combined experimental and
modelling methodologies. It discusses a number of novel elements,
such as the intensification of spent fuel reprocessing and the use
of ionic liquids as green alternatives to organic solvents. The use
of ionic liquids in two-phase liquid-liquid separation is new to
the Multiphase Flow community, and has proved to be challenging,
especially in small channels, because of the surface and
interfacial properties involved, which are very different to those
of common organic solvents. Numerical studies have been also
performed to couple the hydrodynamics at small scale with the mass
transfer. The numerical results, taken together with scale-up
studies, are used to evaluate the applicability of the small-scale
units in reprocessing large volumes of nuclear waste.

This book provides a systematic and comprehensive introduction to
fusion neutronics, covering all key topics from the fundamental
theories and methodologies, as well as a wide range of fusion
system designs and experiments. It is the first-ever book focusing
on the subject of fusion neutronics research. Compared with other
nuclear devices such as fission reactors and accelerators, fusion
systems are normally characterized by their complex geometry and
nuclear physics, which entail new challenges for neutronics such as
complicated modeling, deep penetration, low simulation efficiency,
multi-physics coupling, etc. The book focuses on the neutronic
characteristics of fusion systems and introduces a series of
theories and methodologies that were developed to address the
challenges of fusion neutronics. Further, it introduces readers to
the unique principles and procedures of neutronics design,
experimental methodologies and methodologies for fusion systems.
The book not only highlights the latest advances and trends in the
field, but also draws on the experiences and skills collected in
the author's more than 40 years of research. To make it more
accessible and enhance its practical value, various representative
examples are included to illustrate the application and efficiency
of the methods, designs and experimental techniques discussed.
