Nuclear engineering is an academic discipline that deals with the technologies exploiting nuclear energy, radiation and subatomic particles to benefit people. The Department of Nuclear Engineering (DNE) of SNU is committed to lead globally the education and research needed for the sustainable use of nuclear energy and for diversifying the industrial and medical applications of radiations and various subatomic particles.
“Benefit people with nuclear energy, radiation and plasma”
Nuclear energy can be produced either by nuclear fission or fusion reactions and the origin of the energy is the mass defect involved in each nuclear reaction that is converted to enormous energy according to the mass-energy equivalence law of Einstein. For example, fissioning 1 kg of uranium can generate the energy roughly equivalent to the electricity produced for a day from a 1000 MW power plant. Thus nuclear energy provides very high density and compact energy sources. The most important concern in nuclear engineering is how to utilize nuclear energy in a safe, economical, and environment-friendly manner. There are three main fields at the DNE of SNU: nuclear energy systems engineering, fusion and plasma engineering, and radiation and subatomic particle engineering.
Nuclear fusion reaction is to merge two light nuclei overcoming the repulsive force between two positively charged particles through electromagnetic acceleration in a plasma state. Plasma has been studied actively for realizing self-sustaining nuclear fusion in an engineering device, but it is also being used extensively in numerous industrial applications such as plasma displays and semiconductor circuit printing. In the field of fusion and plasma engineering, the technologies needed for engineering realization of nuclear fusion and diverse applications of plasmas are studied.
Nuclear radiation has made significant contributions to promote the health and security of people through the medical and industrial applications such as medical diagnoses and treatments, and security checking at public facilities. On the contrary, radiations can cause serious damages to the humans and environment if those are not properly shielded. In the field of radiation and subatomic particle engineering, the technologies not only for industrial and medical applications of radiation, but also for environment protection are studied. On the other hand, subatomic particles such as neutrons, protons, and positrons can be used to identify and improve the microscopic structures of materials. Those are mostly produced by particle accelerators. Accelerator technologies and utilization of subatomic particles are studied in this field as well.
At the DNE of SNU, we are performing world-class cutting-edge researches for sustainable use of nuclear energy with the confidence that nuclear energy including nuclear fusion is the only practical means of providing clean and affluent energy to the civilized society. In order to secure the sustainability of nuclear energy, the safety of nuclear power plants must be assured; the spent nuclear fuels have to be properly processed and disposed; and eventually the nuclear fusion power plant should be realized. Researches are conducted for the utilization of plasmas, radiations, and subatomic particles for betterment of human life as well.
