在ITER中将燃烧等离子体物理与聚变技术相结合是建立聚变能选择的战略道路上必不可少的一步。一旦ITER等离子体建立起来，核心等离子体的主要物理参数将与示范聚变反应堆中预期的相同。然而，ITER与下一代反应堆在等离子体表面相互作用方面存在显著差异。主要区别在于对核聚变功率、等离子体组件寿命和运行可靠性的要求。因此，开发一种能够准确解释等离子体表面与核心等离子体相互作用的综合模型，并用于对反应堆进行预测是至关重要的。为了实现这一发展，必须将各种磁聚变装置的研究项目，特别是ITER的研究项目，以及在该领域执行的理论和基础研究项目整合起来。
The integration of burning plasma physics with fusion technologies in ITER is an essential step on the strategic path towards establishing the fusion energy option. Once ITER plasmas are established, the major physics parameters of the core plasma will be in the same range as those expected in the demonstration fusion reactor. However, there is a significant difference between ITER and the next generation reactor with regard to plasma surface interaction. The major differences are in requirements of fusion power, lifetime of plasma-facing components and reliability of operation. Therefore, it is essential to develop an integrated model that can accurately account for plasma surface interactions with a core plasma and can be used to make predictions for a reactor. For this development, research programs in various magnetic fusion devices, especially in ITER, will have to be integrated as well as theoretical and basic research programs executed in this area.
