  Nuclear facilities are scheduled to be abolished in the near future, meaning that large amounts of radioactive scrap metal will be produced in this field. To deal with this problem, new technologies must be developed, because of the radioactivity. In past studies, we investigated the distribution of radionuclides in melting and solidification<sup>1)</sup>, and also the manufacturing technology for concrete bar<sup>2)</sup>. We also conducted basic experiments<sup>3)</sup> and developed a numerical analysis program<sup>4)</sup>. In this paper, we reported on the tests of studies on real size waste vessels with bottom manufactured by centrifugal casting which proved that the centrifugal casting method was one of the most promising processes for recycling the radioactive waste. Moreover, we could prove that the minimum thickness of vessel wall was controlled by solidification time, superheat temperature and coating thickness, and that the critical flow solidus rate was about 0.4 irrespective of materials.
