ABSTRACT
This chapter aims to provide a general outline of nuclear fusion energy with emphasis on technology and materials for fusion reactors. The plasma state, in the context of a fusion reaction, is where the atoms are completely ionized with the nuclei and electrons coexisting as separate entities in a sea of charged particles. The fusion fuel plasma is confined magnetically within a container. The fusion mechanism itself may also be based on inertial confinement. Good heat transfer and thermal properties are the basic requirements of a fusion reactor coolant. The eligibility of carbon for employment in fusion reactors is primarily due to its high melting point. The primary components and materials of nuclear fusion reactors consist of nuclear fuels, structural materials, moderator, reflector and blanket materials, coolants, shields, and non-superconducting and superconducting magnet systems.
