About the book
The development and use of nuclear energy goes back to less than a hundred years ago. Today, according to a report of international atomic energy agency, nuclear energy provides about 20 percent of worldwide electricity. Fission and fusion are two major sources of nuclear energy. Since the first reactor was built, several countries have tried to replace fossil fuels with nuclear power plant. Different types of power reactors are constructed to generate electricity by various countries. Nuclear power reactors include light-water moderated reactors, heavy-water moderated reactors, CANDU pressurized reactors, graphite moderated reactors, gas colled and sodium-cooled fast reactors and future pebble-bed nuclear reactors that are constructed by different technologies. About thirty years ago, the average efficiency of nuclear reactors was barely 50 percent, however, today by improving technology this efficiency has claimed 94 percent. Although nuclear energy produced by fission interaction has advantages over fission as well as fossil energies, despite much efforts and investments in the generation of nuclear energy produced by this method, it is not economically viable.
The purpose of this book is to provide an appropriate reference for nuclear energy research that can be used by researchers and students interested in nuclear energy and technology. Therefore, we invite all researchers and scientists working in this field to assist us in this project.
