Summary

In this presentation, lectures in the school are revisited and a brief summary is given. An emphasis is made to illustrate how the lectures are interconnected so as to constitute the unified basis of knowledge in realizing thermonuclear fusion in ITER.The first message here is the integration of the knowledge. All of conditions (which is imposed by individual characteristic dynamics) must be simultaneously fulfilled. Plasma conditions (density, pressure, current, shape, etc.) set parameter boundaries. Achievement of Q = 10 is expected to be realized near the ridge of boundary, so that exact knowledge of mutual relations between constraints is inevitable. The other message is that, the constraints of plasma, material and design must be subject to a special care. In this regard, the use of tritium in ITER introduces new issue in research. For instance, the containment of tritium in the device leads to a new demand for the system. This issue influences the choice of the wall material. The difference of the wall material (either light element or heavy metal), on the other hand, can have a large impact on confinement. These new features in integration will be explained.The other issue is the need of integration of knowledge to form a law of understanding. The mission of ITER must be realized as fast as possible, considering the fact the necessity for fusion energy will be more keen as time goes on. The operation of ITER has been predicted by extending the empirical scaling relations. More precise prediction and the resolution of possible problems in advance are required. For this urgency, our knowledge must be distilled as a scientific law in which elementary processes are validated.
