The book "Heat and Mass Exchange in Nuclear Power Plants" by Kirillov and Bogoslovskaya is a unique and in-depth study devoted to one of the most relevant aspects of modern nuclear energy. In the face of global climate change and the growing need for sustainable energy sources, understanding heat and mass transfer processes is becoming key to the efficient and safe operation of nuclear reactors. This work not only illuminates the theoretical foundations, but also offers practical solutions, making it an indispensable tool for nuclear power professionals, engineers and technical university students. The book begins with the fundamental concepts of heat and mass exchange, gradually deepening into the complex processes occurring in nuclear installations. The authors consider in detail the physical and chemical processes that affect the efficiency of the reactors, as well as the safety of their operation. The reader will be able to learn about various methods of analysis and modeling of heat and mass exchange, which is especially important for the design of new installations and optimization of existing ones. The intriguing approach of the authors is that they not only present theoretical calculations, but also support them with practical examples from real practice, which makes the material more accessible and understandable. This book will be of interest not only to professional engineers and researchers, but also to students studying nuclear physics and energy. It will be an excellent addition to the training courses, as well as a useful reference material for graduate students and researchers working in the field of nuclear energy. It is also worth noting that the book can attract the attention of those interested in the environmental aspects of energy and seeks to understand how nuclear energy can become part of a sustainable future. The topics raised in the book cover a wide range of issues, including nuclear plant safety, resource efficiency, and environmental impact. The authors emphasize the importance of integrating new technologies and approaches in the field of heat and mass exchange, which can significantly improve the safety and efficiency of nuclear reactors. With the constant development of technology and stricter safety standards, such studies are becoming especially relevant and necessary. Kirillov and Bogoslovska, as authors, have considerable experience in the field of nuclear energy and thermal physics, which allows them to share valuable knowledge and practical recommendations.
