聚变堆等离子体面对材料

Plasma Facing Materials in Fusion Device

介绍了当前核能的利用情况,指出了裂变能的局限性;阐明下个世纪可持续供应的能源将是聚变能。聚变装置中等离子体面对材料(PFM)的研究与开发是一个重要的和决定性的技术问题。根据实验结果和理论计算给出了PFM的设计参数及其应满足的技术要求,介绍了一些实验装置中用作PFM的材料及有望用作PFM的材料,并分析了这些材料的优缺点。

In this paper, there are some concrete data used to show the problem of energy lack, the situation of using nuclear energy, and the limitation of fission energy. It also indicate that fusion energy is only one of the ener-gy sources that can be used continually in next century. In fusion device, PFM is an important and key technical prob-lem. The paper presents the main design parameters for PFM in ITER and the performances PFM should have. and introduces some materials that are or will be used as PFM.
