The development of IVR technology for severe accidents is critical for improved defense in depth. Our proposed honeycomb porous technique significantly improves critical heat flux. Equally important is the development of rapid cooling techniques for high-temperature bodies that ensure rapid transition from film boiling to nucleate boiling regime, even if the timing of water injection is missed. In addition, the combination of honeycomb porous plate and nanofluid is proving effective for rapid cooling of high temperature bodies. This project aims to integrate CHF enhancement and rapid cooling into a single honeycomb cooling technology, thereby advancing IVR capabilities. This presentation summarizes the overall overview of current project and results obtained in the previous project.
