Sukhwinder Singh is conducting research on Accident Tolerant Fuel (ATF) claddings within existing nuclear reactor environments and SMRs, with a particular emphasis on exploring different coatings to enhance the life of Zircaloy fuel claddings under extreme temperature conditions. The development and investigation of different coatings are essential for improving the accident tolerance of nuclear fuel claddings, directly enhancing reactor safety margins and resilience in the face of severe accidents.
