Evaluation of occurrence possibility of tube failure propagation under sodium-water reaction accident is an important issue. In this study, a numerical analysis method to predict occurrence of failure propagation by overheating rupture was constructed to expand application range of an existing computer code. Applicability of the method was constructed through the numerical analysis of the experiment on water vapor discharging in liquid sodium. To improve the evaluation accuracy for the temperature distribution, a Lagrangian particle model for simulating reacting jet was also developed as an alternative method and its basic function was confirmed.

Non-destructive X-ray computed tomography (X-ray CT scanning) is a powerful technique for characterizing the morphology in structural materials as used in medical field. This X-ray CT scanning technique was developed for the purpose of post irradiation examinations (PIE), and applied to the fuel assemblies irradiated in the experimental fast reactor Joyo.

Considering a nuclear fuel recycle system with the FBR,the nuclear properties for an "Equilibrium Core",in which the self-generated MAs and LLFPs are confined and incinerated,is investigated.The purpose of this study is firstly to show the specific characteristics of the "Equilibrium Core" from the viewpoint of nuclear properties,and secondary to prospect whether the conventional design concept of the FBR needs to be changed for realizing the "Equilibrium Core".
