Nuclear Safety Applications

Development of high performance thermoelectric energy harvester for nuclear safety applications

Waste heat recycling a green solution for sustainable energy challenges


Safety is the key concern in nuclear industry especially after Fukushima accident in Japan. There are continued efforts to improve safety of nuclear power reactors. A major concern with nuclear energy is the safe storage of the spent nuclear fuel before final disposal. Development of efficient and reliable thermoelectric nanostructured bulk materials have crosscutting significance in nuclear industry as it enables self-powered sensor technology in reactors and spent fuel storage facilities to improve their safety.

Our Research

Our research at SET Center focuses to enhance energy conversion efficiency of the commercial thermoelectric materials through a combinatorial technique of nano-structuring and non-inclusion for device fabrication in nuclear industry. The interconnected network of low dimension nanostructures in the matrix will act as a conduit for electron transport while the enhanced boundary scattering of phonon through the compacted nanostructures in the composite will provide the extremely low thermal conductivity and thus the performance of thermoelectric materials will be improved in an economical and commercially scalable route for device fabrication in nuclear industry.
