S054091 Evaluation for Flow-Induced Vibration of a Primary Circuit Hot-Leg Piping in a Sodium-Cooled Fast Reactor (1) : Approach to the Evaluation Methodology Development

Abstract

Experimental and analytical evaluations are carried out to develop the evaluation methodology of flow-induced vibration in a large-diameter piping with elbow for the purpose of ensuring the feasibility of a sodium-cooled fast reactor design, where a large-sized electric power is aimed with a two-loop configuration in the cooling system. This paper describes approach to the evaluation methodology development and the overview of research and development for the primary hot-leg piping.
