Introduction to Nuclear Materials (2017)

강좌 개요

❍ This course introduces students to basic concepts and theories that are needed to understand the behavior of materials in nuclear reactors. It is designed for both undergraduate and graduate students, who have already studied thermodynamics. The knowledge on materials science is not pre-required. The course is mainly composed of 4 contents:
(1) Review of thermodynamics: We will review basics of thermodynamics, which is needed to systematically understand the behavior of materials, including the concept of entropy and free energies, equilibrium theory, and rate theory.
(2) Introduction to materials science: We will learn fundamental concepts of materials science, such as crystalline structure, materials mechanics, defects in solids, diffusion in solids, etc. We will focus on solid materials.
(3) Radiation damage processes: We will learn what happens when a high-energy particle such as fast neutron comes into a solid material, what kinds of damages are created, and how damages recover/accumulate in a material.
(4) Radiation effects on material properties: We will learn what kind of adverse consequences are brought by radiation damages. Some cases of radiation effects on structural/mechanical/thermal properties of materials will be introduced.
