Outline and Purpose of the Course	Nuclear fusion reactors and fission reactors present severe challenges such as high temperatures, high pressure, and high radiation fields, and the nuclear materials used in them are selected with reference to various properties. This course describes in detail major nuclear materials such as nuclear fusion reactor blankets, plasma facing materials, reactor pressure vessels, and fuel cladding, as well as other nuclear materials. Also, we hold roundtable discussions to learn about the latest breakthroughs in research and development.
Course Goals	The goal of the course is to understand how the performance and safety of systems such as nuclear fusion reactors and fission reactors are related to the properties of materials, and to comprehend trends in materials research for improving performance and safety.
Schedule and Contents	Fission reactor materials, 5 classes: Give an overview of fission reactors and discuss the below components. - Fuel (recoverable reserves, uranium abundance ratio, nuclear cross sections, MOX) - Cladding material (zirconium alloy, corrosion, hydrogen embrittlement) - Control material (absorption cross sections, control rods, burnable poisons) - Moderators (scattering cross sections, moderating efficiency, diffusion length) - Coolants (thermal properties, radioactivation, furnace types) - Structural materials (pressure vessels, mechanical properties, radiation damages) Nuclear fusion reactor materials, 4 classes: Give an overview of nuclear fusion reactors and explain their development history (tokamak, helical, inertial) as well as the below components. - Structural materials (radioactivation, radiation damages, mechanical properties, effects of 14MeV neutrons) - Coil materials (alloy superconductivity, compound superconductivity) - Blankets (tritium breeding materials, neutron multiplication materials, fuel cycle) - Plasma facing materials (loss and redeposition, hydrogen recycling, tritium inventory and leakage) Latest research trends, 5 classes: Students present information they have researched on the latest in research and development, and related question and answer sessions and debates are held. Feedback class, 1 lecture: Review the reports assigned in class as well as students’ presentations and question and answer sessions.
Evaluation Methods and Policy	Grade is based on active participation in class, including question and answer sessions, reports and presentations. Reports will be evaluated based on attainment of goals. It is required to hand in both reports, and those that show independent thinking will be given high scores.
Course Requirements	None
Study outside of Class (preparation and review)	None.
Textbooks	Textbooks/References	In addition, printouts will be distributed in class.
