Sodium using for past experiments was maintained at the sodium technology development facility in Oarai Research and Development Center. But the oldest dump tank of the sodium was fabricated over forty years ago. It is necessary to keep it safer and more stable condition. Therefore transportation of the sodium from the facility to a new facility was planned not only to keep it safer and more stable condition but also to reuse it for other sodium experiments. Such a large amount of sodium has never been transported between two facilities in Japan. Pipe transportation between two facilities was selected by considering safety, operating efficiency and cost. The transportation equipment with over 200 meters long pipes was constructed and sodium transportation was operated. Total amount of the transported sodium was about 270 m and the flow rate was 12m/h on average.
