Dr. Ritesh Mohun
Advanced Reactor Materials Research Officer
Ritesh Mohun was appointed as Advanced Reactor Materials Research Officer at the Nuclear Futures Institute in April 2022. His research focusses on developing novel materials, investigating material behaviour in extreme environments (including nuclear and aerospace), and combining materials modelling techniques with experimental methods. He also assists for a range of uranium-active laboratories as well as a high temperature flowing lead setup that will be used to study the behaviour of materials under lead-fast reactor and fusion reactor conditions.
He previously worked as Research Associate at the University of Sheffield (2018–2022) on the evolution and interaction of spent nuclear fuel under simulated geological environment. His research focussed on the use of non-destructive characterisation techniques, such as X-ray diffraction, scanning electron microscope, Raman spectroscopy, X-ray absorption spectroscopy, Positron annihilation spectroscopy and Luminescence spectroscopy, amongst others, to quantify the impact of radiation damage induced by unstable radionuclide decay events on the structural stability of irradiated nuclear fuels. He also investigated the effects of microstructure and impurity doping on the chemical durability of uranium-based fuels in order to enable reliable degradation prediction and repository condition adjustment to achieve desired performance.
Ritesh Mohun received his PhD in Physics and Materials Science from Aix-Marseille University and CEA-France, where he designed an in-situ Raman spectroscopy installation capable of characterising alterations near a nuclear fuel-water interface and the formation of U-secondary phases under oxidising conditions. He earned a BEng degree in Chemical and Renewable Energy Engineering from the University of Mauritius, then Master degrees in Nuclear Engineering from the Polytechnic University of Catalonia in Spain and Materials Science for Nuclear Energy from the Grenoble INP in France.
