Motivated by understanding of severe accident phenomena, extensive studies have been conducted to investigate the thermal-hydraulics both debris bed and melt pool which may form during a light water reactors. However, little work has done address remelting phenomenon following uncoolable bed, although it plays an important role in formation progression. The present study is intended fill knowledge gap. For this purpose, test facility was developed process particulate packed with two-component particles. Electric heating employed simulate decay heat. This paper presents detailed description design, including rationales simulant materials for oxidic metallic components corium, estimation power distribution, design simulation rod, selection validation instrumentation as well commissioning experimental facility.
