Abstract. In the course of the ITER EDA, an extensive
collaboration amongst the major communities in the international magnetic
confinement fusion programme has assembled a comprehensive description of the
physics of tokamak plasmas. The ITER Physics Basis provides rules and
methodologies for the extrapolation of plasma behaviour to the ITER scale and
underpins both projections of plasma performance in, and the engineering
design of, ITER. The major focus of the work has been the development of
scalings and models for core, edge, and divertor plasmas in the ITER reference
scenario, the ELMy H-mode. In addition, data relevant to ITER's ultimate goal
of steady-state operation has been incorporated. Here the major elements of
the ITER Physics Basis are summarized in terms of the understanding developed
in the areas of plasma confinement, mhd stability and operational boundaries,
the physics of edge and divertor plasmas, and energetic particle behaviour.
