This diploma begins with an introduction to nuclear physics and the fundamental principles governing nuclear reactions and reactors. It progresses into an in-depth exploration of reactor components, systems, and operational mechanisms, including coolant systems, control mechanisms, and safety systems. The curriculum emphasizes reactor kinetics and dynamics, providing insights into neutron kinetics, feedback mechanisms, and transient analysis. Various reactor types, such as Pressurized Water Reactors (PWRs), Boiling Water Reactors (BWRs), and advanced designs, are discussed in detail, along with their applications in power generation, research, and other sectors. The course also addresses the nuclear fuel cycle, including enrichment, fuel fabrication, and waste management, highlighting the importance of sustainability and environmental responsibility. Safety and regulatory frameworks are key components, with lessons covering nuclear safety principles, emergency preparedness, and historical case studies of nuclear accidents. In the final stages, students explore current trends and future advancements in nuclear technology, such as fusion reactors and innovative designs. The capstone project serves as a practical culmination of the course, allowing students to apply their knowledge in a hands-on project and showcase their understanding through presentations.
