The Engineering Design Activities (EDA) for an international Thermonuc
lear Experimental Reactor (ITER) were established on 21 July 1992 by a
n agreement between the European Atomic Energy Community the Governmen
t of Japan, the Government of the Russian Federation and the Governmen
t of the USA. The overall programmatic objective is to demonstrate the
scientific and technological feasibility of fusion energy for peacefu
l purposes. The engineering objectives are to establish the design of
ITER in such a way that controlled ignition and extended burn of a fus
ion plasma can be demonstrated, essential reactor technologies can be
demonstrated in an integrated system, and integrated tests of high hea
t flux and nuclear components can be performed. This article outlines
the fusion process and the tokamak concept used for ITER and summarise
s the potential advantages of fusion energy. The objectives of the EDA
are presented together with the organisational structure to translate
them into a design. Finally the ITER parameters and design status are
reported; and a brief overview of time planning and cost is given. Co
