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.

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和热负荷；为此作了必要的先行准备计算工作。
