Light Water Reactors: Design and Operation

This lecture covers the design and operation of Light Water Reactors (LWRs), focusing on Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs). Topics include the primary circuit components, materials selection for nuclear fuel, fuel rod cladding, zirconium cladding oxidation, steam generators, pressurizers, coolant circulation, and safety systems. The instructor explains the construction of key components, such as steam generators and pressurizers, and discusses the role of barriers in LWRs. The lecture also addresses the challenges of zirconium cladding oxidation and the importance of maintaining proper coolant circulation to prevent dryout in the core.
