Research Projects

The high flux of deuterium, tritium, and helium plasmas, 14.1 MeV fast neutron irradiation, and high surface temperatures in advanced nuclear reactors can modify the structural, thermal, and mechanical properties of host materials. High dose radiation can cause cracking, voids, and damage, leading to structural defects. To enhance radiation stability, materials can be removed from these areas. Nanostructured materials have gained attention due to their improved radiation resistance, with high density of grain boundaries and hetero-interfaces acting as defect sinks. These interfaces can control thermal, mechanical, and structural behavior by choosing appropriate layer thickness and materials. Tungsten (W), a refractory transition metal with a high melting point, is expected to be a suitable plasma-facing component and structural material for future nuclear fusion reactors. This project aims to explore the structural stability and radiation-induced defect dynamics at interfaces under ion irradiation in tungsten-based nano-multilayers. The lack of suitable materials is a significant challenge for future reactor development. The project aims to generate quality output and establish a strong position in international research, potentially useful for future nuclear reactor programs.
