India’s PFBR attains criticality at last
Prime Minister Narendra Modi proclaimed it “a proud moment for India” when on April 6 the 500-MWe, sodium-cooled Prototype Fast Breeder Reactor (PFBR) achieved initial criticality. This milestone, which comes some 22 years after the continually delayed PFBR project began, marks India’s entrance into the second stage of its three-stage nuclear program, which has the ultimate goal of supporting the country’s nuclear power program with its significant thorium reserves.
Advances in Nuclear Fuel Management (ANFM 2025)
Dr. G. Ivan Maldonado is a Professor of Nuclear Engineering at the University of Tennessee (UT) Department of Nuclear Engineering and Fellow of the American Nuclear Society (ANS). He has been affiliated with the US nuclear industry for more than 30 years, with expertise in computational modeling and simulation of current and next-generation nuclear reactors and specialization in nuclear fuel management optimization. He has led a multitude of research and instructional projects with students at three universities (Iowa State, Univ. of Cincinnati, and UT) and with colleagues nationally and internationally, while mentoring 23 PhD and 50 MS graduates in the process, so far. Past projects have involved core neutronics for PWRs, BWRs, SMRs, CANDUs, VVERs, FHR (salt-cooled), MSRs, and most recently fusion reactors. Dr. Maldonado has published around 250 peer-reviewed publications with his students, has been a consultant to the US NRC ACRS, Guest Editor to the Progress in Nuclear Energy and Annals of Nuclear Energy journals, served as Technical Program Chair and Division Chair for the ANS Reactor Physics Division (RPD), and was a former Technical Program Manager with GE Nuclear Energy / Global Nuclear Fuels in support of core/bundle design, licensing, and operational management of BWR reactors in the US and abroad.
