Belle R. Upadhyaya

Professor Emeritus


Belle R. Upadhyaya received the PhD degree in engineering sciences (systems science) from the University of California at San Diego. He is currently a professor of nuclear engineering at the University of Tennessee, Knoxville. His research and teaching interests include instrumentation and controls, reactor dynamics, advanced digital signal processing, power and process plant monitoring and diagnosis, autonomous and fault-tolerant control of small modular reactors, nuclear desalination, sensor placement strategies, accelerated aging of detectors and equipment, nondestructive examination, nuclear safeguards, and reliability and maintainability engineering.

Professor Upadhyaya is an elected Fellow of the American Nuclear Society (ANS), an elected Fellow of the International Society of Automation (ISA), and a life senior member of the Institute of Electrical and Electronics Engineers (IEEE). He has published over 325 articles in scientific journals and conference proceedings, chapters in handbooks, and is the author or co-author of over 130 research reports.

He was a Visiting Research Scientist/Lecturer at Commissariat a L'Energie Atomique, Saclay, France; Netherlands Energy Research Foundation (ECN), Petten, The Netherlands; National University of Mar del Plata, Argentina; Electricite de France, Chatou, France; Instituto de Pesquisas Energeticas e Nucleares (IPEN), Sao Paulo, Brazil; IAEA expert mission to IPEN, Sao Paulo, Brazil; delegate, IAEA Coordinated Research Project, Vienna; Korea Atomic Energy Research Institute, Daejeon, Rep. of Korea.
