This book explores the rapidly evolving field of nuclear microreactors, covering their fundamental technological principles, design concepts, operational conditions, safety features, deployment strategies, and applications. As energy demands change and the need for decentralized, resilient, and decarbonized power solutions increases, microreactors present an alternative to traditional power generation. The book thoroughly discusses design considerations, engineering challenges, and regulatory issues, while also describing non-electric applications such as district heating, hydrogen production, desalination, and nuclear-renewable hybrid energy systems. It concludes by evaluating emerging trends, technological innovations, and the role of microreactors in the global transition to a decarbonized yet resilient supply of electricity and heat.

Nuclear Principles in Microreactor Technology serves as a definitive guide to nuclear microreactor technology, offering a balanced mix of theory, application, and future insights. With the growing interest in compact nuclear power solutions, this book is a valuable resource for professionals, researchers, and decision-makers who are shaping the future of clean, reliable energy.

Dr. Tatjana Jevremovic is a Senior Manager in Nuclear Technology & Regulations at Sargent & Lundy Company in the USA. Before this role, she served as A/Section Head and Team Leader for Water Cooled Reactor Technology Development in the Nuclear Power Technology Development Section at the International Atomic Energy Agency (IAEA). Dr. Jevremovic also chaired the Technical Selection Committee of the IAEA’s Marie Curie-Sklodowska Fellowship Programme (MSCFP), which aims to encourage women to pursue graduate-level nuclear-related studies. Additionally, she was the Technical Lead of the IAEA Lise Meitner Program, focused on advancing and retaining female experts in nuclear-related fields globally. Dr. Jevremovic spent 11 years in Japan, where she first earned her Ph.D. in Nuclear Engineering from the University of Tokyo. She then served as a professor at the University of Tokyo before becoming Chief Engineer at Nuclear Fuel Industries, Ltd. During her time there, she developed a novel methodology for nuclear reactor physics assessments that is still used today for relicensing nuclear power plants in Japan. Later, she relocated to the USA, where she held the prestigious position of Chair Professor at the University of Utah. She also led the Nuclear Engineering Program and served as Director of the university's research reactor. Dr. Jevremovic has published over 200 papers in journals and conferences, has graduated over 40 students who all hold responsible positions in the nuclear sector worldwide, and she serves on numerous national and international committees.
