Chemomechanical Interactions Resulting from Fuel-Alkali Metal Reactions inside LMFBR Oxide Fuel Elements

摘要

Chemomechanical interactions inside metal-clad fuel elements are defined as those fuel-cladding mechanical interactions (FCMI) that are influenced by or result from chemical reactions between constituents of the irradiated fuel system. The purpose of the present paper is to interpret some recent experimental and analytical results in terms of chemomechanical reaction mechanisms, with special emphasis on the modeling of breached LMFBR oxide fuel pin behavior.
