In 1959, when the Journal of Nuclear Materials was created, the first Tokamak fusion device had just began operation in Russia while commercial electricity production using nuclear fission was already a reality, albeit in some cases at small scale, with several reactors of various types in operation worldwide, such as the Vallecitos boiling water reactor and the …
The history fission and fusion is rather short and very convoluted, so a brief description of the two processes is a good place to start. Simply put, "fission" is a nuclear process in which an atom is split (or decays) to form two smaller atoms while releasing a quantity of energy.
Uranium Mining Techniques. The extraction of uranium, a dense and energy-rich element, has evolved significantly. Initially, conventional methods like open-pit and underground mining were used. Open-pit mining involves removing surface material to access uranium …

What is Nuclear Fission? Nuclear fission is a nuclear reaction in which the nucleus of an atom is bombarded with low-energy neutrons which splits the nucleus into smaller nuclei. An abundant amount of energy is released in this process. Nuclear fission reactions are used in nuclear power reactors since it is easy to control and produces large ...
Fusion and fission reactions are profoundly dependent on hydrogen for sustained reactions. Fusion is fueled by the isotopes of hydrogen, and predominantly hydrogen-based moderators slow fission neutrons to propagate chain reactions. Intentional tritium production in fusion and concomitant tritium production in fission reactors introduce challenges.

Nuclear fusion is different from nuclear fission, where heavy atoms such as uranium are split by neutrons into two or more new atoms with less mass, and released kinetic energy of the lost mass is then used to heat the surrounding water, resulting in steam, which in turn propels the turbine to produce electricity [35]. Nuclear fusion, however ...
