Nuclear fuel assembly design and fabrication

W. Wiesenack,     Institutt for Energiteknikk, Norway

Abstract:

Fuel assemblies and their components are subjected to the most harsh conditions existing in a nuclear reactor. They are designed and manufactured to satisfy stringent functional and safety requirements for normal operation and transient conditions. With an emphasis on boiling and pressurised light water reactors and going from general principles to details, the chapter describes the main components of a fuel assembly and how design and functionality are related to operating conditions, safety criteria and reactor physics. Phenomena affecting fuel rod endurance are addressed and illustrated.
