Nitendra Singh is a nuclear engineer with expertise in nuclear safety and design working at ITER organization as a Project Associate responsible for the safety assessment of Tritium Breeding Blanket Systems (TBBS). He holds a Doctorate in Nuclear Engineering from Homi Bhabha National Institute (HBNI), India; a Master in Nuclear Engineering from Université Paris Sud-XI (now, Paris-Saclay), France and a Master of Technology in Nuclear Science and Technology from the University of Delhi, India. He has management diplomas in Nuclear Energy Management from IAEA, Austria, and in Nuclear Knowledge Management from the Moscow Engineering Physics Institute (MEPhI), Russia.His technical expertise includes Nuclear Severe Accident Management, Nuclear Safety Design and Passive Systems, Tritium Breeding Blanket Systems, and Advanced Nuclear Reactor Core Design. He has authored several publications in severe accident safety design, and fast breeder reactor core designHis book “Basic Concepts Behind Fast Breeder Reactor Core Design” sets an example for advanced second stage of the India’s three stage Nuclear Program. He is the only scientist in the country who has performed the hands-on experimental program on melt-water interaction towards the design of indigenous core catcher. The innovative severe accident safety system is key to address Fukushima kind of scenarios.His design study on long-life core fuel pin design for the Indian fast breeder reactor using internal breeding gain concept, set up a basis for long-term utilisation of reactor core. This concept will be backbone of “Sookshma”.In addition, he is an avid speaker on advanced nuclear systems, fusion technology, nuclear and fusion policy, and climate change actions. He is the founder of the Indian Youth Nuclear Society (IYNS) and the Women in Nuclear in India association (WiN-India) and co-founded the Women in Fusion (WiF) international organization, Nuclear4Climate initiative, and InFusEd (International Fusion Energy Education) initiatives at ITER. Furthermore, he is the founder and CEO of “IYNS: Tech-Solutions” and working towards design of India’s First Micro Reactor “SUK-M (Sookshma)”.
