It is the important problem to comprehend thermal-hydrauric phenomena inside of reactor vessel, on designing structure. To help understanding 3-dimentional complex flow, visualizing result of computer simulation has been required. The animation about computed flow inside of tank-type fast breeder reacter vessel, constant flow that spouts from the core, taken in by the intermediate heat exchanger (IHX), had been made by computer graphic technices The 3-dimensional flow was visualized by 1000 motional and perspective marker particles in the 1/6 reactor vessel coverd with semitransparent wall. In a case, view point was fixed, in another, the moving view point around the object reduces blind spots.
