A broad review is presented of the status and outlook of achieving fus
ion energy production by the confinement of high temperature plasmas w
ith magnetic fields. The paper describes the basic features of the fus
ion process, plasma confinement principles and concepts with emphasis
on the Tokamak, issues of materials development, descriptions of the m
ajor components and subsystems of fusion reactors, prospects for power
plants, the policy in the United States of magnetic fusion energy and
the international aspects of this endeavor. (C) 1998 Elsevier Science
