One strategy for severe accidents is in-vessel retention (IVR) of corium debris. IVR consists of external cooling of the reactor vessel in order to remove decay heat from the molten core through the lower head of the vessel. However, heat removal is limited by the occurrence of the critical heat flux condition (CHF) at the outer surface of the reactor vessel. Therefore we proposed the CHF enhancement technique in a saturated pool boiling by attachment of a honeycomb porous plate (HPP) on the heated surface. However, the reactor vessel to install HPP has curvature, so the key succeeding in IVR depends on how to place the HPP on the surface of reactor vessel with curvature. Accordingly, we propose the way using porous cellulose beads and nanofluid. As a result, the CHF is shown to be enhanced double compared with that of a plain surface of distilled water.
