The upper structure of fuel assembly for the next generation sodium-cooled fast reactor, including the method of dissimilar connection between wrapper tube and handling head and the structure of the upper shield, was conceptually designed to fulfill functional requirements within a tentative limit of temperature to use wrapper tube material, based on the result of computational fluid dynamics (CFD) analysis.

In the design of the next generation sodium fast reactor (SFR), reinforcement of the design in terms of independency, diversity and multipleness is required. To meet this requirement, optimal configuration of emergency power supply system for next generation SFR is investigated and concept of this configuration is established.
