FIGURE 2.8 Tokamak reactor schematic sketch.
Some requirements imposed on the reactor systems are self-evident. They
result from the conceptual and engineering analyses of different project ver-
sions.
The tokamak design principles and structure (Fig. 2.8) are now defined. Its
key systems are the following:
l MS, including the toroidal and poloidal field coils, the central solenoid, the
active controlling coils and the correction coils;
l vacuum vessel with in-vessel components and ports;
l plasma additional heating and current drive systems;
l blanket and radiation shield;
l control system for plasma position and shape;
l vacuum pumping and tritium system;
l diagnostics and control system;
l power supply system.
In the case of a commercial reactor, the mentioned systems, relating to the
tokamak itself, are complemented by general plant equipment and facilities, in-
cluding an energy transformation system, equipment for the repair and replace-
ment of deteriorated items, and so on.
