Preliminary Stress Analysis for Receptacle of Prototype Sodium-cooled fast Reactor

The receptacle is responsible for supporting the weight of the fuel assembly and retaining the primary sodium flow path up to the fuel assembly. In terms of preventing the core meltdown, it is important to make the receptacle design have enough structural integrity. The purpose of this paper is to evaluate the integrity of the receptacle regarding the weight loads of the dead weight and the fuel assembly following ASME code. This paper evaluated the integrity of the receptacle with respect to the design condition and the steady-state condition of the level A condition. According evaluation results, the receptacle design has enough design margins and satisfies the design criteria defined ASME code
