Recent innovations in material science has led to a range of new materials being identified as being usable within nuclear reactor cores, these range from SiC based ceramics, to novel alloys such as FeCrAl, and to hybrids with both metallic and ceramic properties. One specific area that is become more timely is the potential use of binary carbides such as SiC-SiC which is a system based on two distinct SiC phases. This proposal takes this work as a concept, modifying it to use SiC and TiC, two carbides with different material properties, but which together may have advantageous properties when used within a nuclear core.This proposal examines the effects of damage on the interfaces between the TiC and SiC, for example the impact of differential expansion due to induced damage, or the potential for fission gas bubble formation at the interfaces. These are just two of the potential issues that face such systems and which are part of this work.The project utilises the unique facilities at Argonne National Laboratory (IVEM-TANDEM), and at Oak Ridge National Laboratory (LAMDA), in concert with the ATR-NSUF programme providing access.

材料科学的最新创新导致一系列新材料被确定为在核反应堆核心中可用的，这些材料从基于SIC的陶瓷到新型合金，例如繁殖力，以及具有金属和陶瓷特性的混合体。一个更及时的特定区域是二元碳化物（例如SIC-SIC）的潜在用途，SIC-SIC是一个基于两个不同的SIC阶段的系统。这项建议将这项工作作为一个概念，将其修改为使用SIC和TIC，这是两个具有不同材料特性的碳化物，但在核心核中使用时可能具有有利的特性。该提案研究了损坏对TIC和SIC之间接口的影响，例如，由于诱导的损坏而导致的损害造成的差异损坏的影响，或者可能导致了裂变气体泡沫的造成的损害。这些只是该系统面临的两个潜在问题。该项目利用Argonne国家实验室（IVEM-TANDEM）的独特设施，以及与ATR-NSUF计划一起提供访问权限的Oak Ridge National Laboratory（LAMDA）。
