The 2011 Fukushima Daiichi disaster raises the requirement of accident tolerant fuel (ATF) cladding. As promising candidates, the FeCrAl ternary alloy and SiC fiber reinforced SiC matrix (SiC/SiC) composites are discussed with details for recent development, as well as the issues of their in-core application and fabrication. Herein, the design of materials based on the Materials Genome Initiative (MGI) is introduced as the effective scheme in accelerating the development for ATF claddings. Correspondingly, the potential technical routes are provided and some examples of preliminary modelling studies as the preparation steps for MGI are presented.

2011年的福岛第一核电站灾难提高了对事故容忍燃料（ATF）包层的要求。FeCrAl三元合金和SiC纤维增强SiC基质（SiC / SiC）复合材料作为有前途的候选者，将详细讨论最新进展，以及它们在堆芯中的应用和制造问题。在此，介绍了基于材料基因组计划（MGI）的材料设计，作为加速ATF覆层开发的有效方案。相应地，提供了潜在的技术路线，并提供了一些初步建模研究的实例，作为MGI的制备步骤。
