An important aspect of nuclear reactor core analysis involves the determination of the optimal coolant flow distribution and pressure drop across the reactor core. On the one hand, higher coolant flow rates will lead to better heat transfer coefficients and higher Critical Heat Flux (CHF) limits. On the other hand, higher flows rates will also in large pressure drops across the reactor core, hence larger required pumping powers and larger dynamic loads on the core components.
This book includes contributions from researchers around the world on numerical developments and applications to predict fluid flow and heat transfer, with an emphasis on thermal hydraulics computational fluid dynamics. Our ability to simulate larger problems with greater fidelity has vastly expanded over the past decade. The collection of material presented in this book augments the ever-increasing body of knowledge concerning the important topic of thermal hydraulics.
AT THE transition to the new millennium the future of nuclear energy looks
brighter. Nuclear power plants worldwide have operated safely.
Applications for extension of reactor operating licenses in the U.S. are in
place and construction is continuing abroad.
Uses of isotopes and radiation in applications to medicine, research, and
industry continue to assure human benefit. Research and development are
active in the areas of controlled fusion, accelerator uses, isotope separation,
space exploration, and excess weapons material disposition.
This book covers various topics, from thermal-hydraulic analysis to the safety analysis of nuclear power plant. It does not focus only on current power plant issues. Instead, it aims to address the challenging ideas that can be implemented in and used for the development of future nuclear power plants. This book will take the readers into the world of innovative research and development of future plants. Find your interests inside this book!Steam Generator
This introduction to nuclear physics provides an excellent basis for a core undergraduate course in this area. The authors show how simple models can provide an understanding of the properties of nuclei, both in their ground and excited states, and of the nature of nuclear reactions. They include chapters on nuclear fission, its application in nuclear power reactors, the role of nuclear physics in energy production and nucleosynthesis in stars.
One of the main missions of the Abdus Salam International Centre for
Theoretical Physics in Trieste, Italy, founded in 1964, is to foster the growth
of advanced studies and scientific research in developing countries. To this
end, the Centre organizes a number of schools and workshops in a variety of
physical and mathematical disciplines.

NASA’s budget for fiscal year 2003 included funds to begin the Nuclear Systems Initiative focused on
research into and development of enhanced capabilities in the general areas of spacecraft power and propulsion
Presently, India occupies a leading place among Asian nations in the indigenous design, development, construction, and operation of nuclear power reactors. Nuclear power generation in India is based on a three-stage plan to eventually make use of the abundant national resources of thorium, through the use of fast breeder reactors. To achieve this long-range goal, India had to necessarily start with setting up heavy water–moderated, natural uranium–fueled power reactors to produce the plutonium required for the subsequent stages....
The world faces serious difficulties in obtaining the energy that will be needed in coming decades for a growing population, especially given the problem of climate change caused by fossil fuel use. This book presents a view of nuclear energy as an important carbon-free energy option. It discusses the nuclear fuel cycle, the types of reactors used today and proposed for the future, nuclear waste disposal, reactor accidents and reactor safety, nuclear weapon proliferation, and the cost of electric power.
Private landowners or Federal Agencies responsible for cleaning up radiological environments are faced with the challenge of clearly defining the nature and extent of radiological contamination, implementing remedial alternatives, then statistically verifying that cleanup objectives have been met.
The book "Applied Fracture Mechanics" presents a collection of articles on application of fracture mechanics methods to materials science, medicine, and engineering. In thirteen chapters, a wide range of topics is discussed, including strength of biological tissues, safety of nuclear reactor components, fatigue effects in pipelines, environmental effects on fracture among others. In addition, the book presents mathematical and computational methods underlying the fracture mechanics applications, and also developments in statistical modeling of fatigue.
During my career, some 35 years, there has been a growing realization that
the goal of successful nuclear waste management and the final disposal of
long-lived radionuclides can only be attained by a thorough understanding
of the behavior of key, technogenic radionuclides in the environment. Within
a nuclear reactor, these radionuclides are created by fission, neutron capture
and subsequent beta-decay reactions on actinides, mainly
U, and by
activation nuclear reactions.
With the amazing advances of scientific research, Hydrodynamics - Theory and Application presents the engineering applications of hydrodynamics from many countries around the world. A wide range of topics are covered in this book, including the theoretical, experimental, and numerical investigations on various subjects related to hydrodynamic problems. The book consists of twelve chapters, each of which is edited separately and deals with a specific topic. The book is intended to be a useful reference to the readers who are working in this field....
In 1932, James Chadwick discovered the neutron, but initially the only sources
of neutrons were from the radioactive decay of unstable nuclei. It was not until
1942 when Enrico Fermi constructed the first nuclear reactor in the squash
courts beneath the University of Chicago’s Stagg Field, that a controlled and
sustained nuclear chain reaction was achieved. After World War II, nuclear
reactors became available for civilian research, and in 1945 Ernest Wollan set
up a double-crystal diffractometer at ORNL’s Graphite Reactor. This marks
the beginning of neutron scattering....
