Energy takes form in terms of light, electricity, chemicals, machine, nuclear energy, and heat, and to understand, manufacture, convert, and apply it, it is important to have a broad knowledge of areas such as physics and chemistry. The Quantum Energy Engineering Course encompasses the basic sciences, which provide the foundation for studying the methodologies for working on various energy-related research topics. The pillars of this course are quantum energy (nuclear fission and nuclear fusion), nuclear power technology (front-end and back-end), laser beam engineering (medical applications and radiation usage), and material science (energy conversion materials, biomaterials). The course aims to create individuals with strong basic knowledge and strong expertise who could become actively involved in research institutes or the manufacturing industry.

Nuclear Fusion / Thermal Hydraulics in LMFBR / Fundamental Energy Physics
The physics of energy and momentum flow in conductive fluids is addressed in relation to the Maxwell tensor in Fourier space. The dynamic control of a structure in equilibrium with turbulence is thus our main focus. The practical media under consideration are the liquid metal in a fast breeder reactor and the magnetized plasmas in a fusion reactor or space engine. In addition, given the requirements for the optimum resolution in the measurement of the electric and magnetic fields, macroscopic quantum control methods are comprehensively explored.
Radiation physics and engineering for advanced medical and industrial applications / Neutron engineering studies for nuclear fusion reactor (fusion neutronics) and boron neutron capture therapy (BNCT)
We study radiation physics and engineering for advanced medical and industrial applications. In 1981, we constructed OKTAVIAN, the world’s most powerful 14 MeV neutron source facility, at Osaka University. Subsequently, neutronics (neutron engineering) studies in relation to nuclear fusion reactors and boron neutron capture therapy (BNCT) (a new cancer therapy) have been undertaken using OKTAVIAN.
