NUCLEAR SYSTEMS. THERMAL HYDRAULIC FUNDAMENTALS

Focusing on thermal hydraulic design and analysis of the nuclear core, this textbook examines nuclear systems, allowing students to develop the knowledge and design skills needed for working with the next generation of nuclear reactors. It addresses the stress integration of fluid flow and heat transfer, various reactor types, and energy source distribution. This edition covers recent nuclear reactor concepts such as Generation III+ and IV reactors as well as new power cycles. It features new examples using concept parameters along with new chapter problems. A solutions manual is available upon qualifying course adoption.
