ITER第一壁、偏滤器靶板和壁的热负荷计算

ITER-FEAT是国际热核聚变实验堆设计，除了继续演示聚变物理和D-T燃烧的科学可行性外，更重要的是为了演示包层整体组合、氚增殖、氚回收、氚泄漏等工程问题。在设计包层时，需要进行中子学计算得到氚增殖率、辐射损伤率、活化放射性强度、磁体及其屏蔽厚度的计算、核加热产生率和冷却系统设计和安排的必要数据，而这一切都必须先知道第一壁和偏滤器靶板的中子壁负荷(即中子功率通量)和热负荷；为此作了必要的先行准备计算工作。

Power Flux Calculation of First Wail, Divertor Plate and Wall of ITER

ITER-FEAT is the design of international thermonuclear experimental reactor. Except for to demonstrate scientific feasibility of fusion physics and D-T reaction, it is more important that it will demonstrate the technology of blanket, tritium breeding, tritium recovery and tritium leak. When blanket is designed, some necessary data, including tritium breeding ratio, irradiation damage ratio, intensity of activation radiation, magnet and thickness of shield, can be get through neutronics calculation. All of that must base on heat load and neutron power flux of first wall and divertor plate. So, the preparative calculation is prformed for that.
