title = "Preliminary Experimental Study on Suppression of Steam Explosion with Superabsorbent Polymer Microbeads",
abstract = "During a hypothesis severe accident scenario in pressurized water reactor (PWR), the melt corium interact with coolant water, potentially triggering steam explosions due to fuel{\textendash}coolant interactions (FCI). Such explosions threaten containment integrity, making the study of suppression mechanisms critical. Preliminary experiments conducted on the VULCAN facility revealed that the suppression effect on steam explosion intensity and triggering probability could be achieved through SAP microbead-mediated multiphase interactions. Small melt jets fragmenting in subcooled water induce steam explosions. Superabsorbent polymer microbeads suppress this by altering jet breakup, vaporization, and pressure waves, disrupting FCI and inhibiting energy release. The findings from preliminary experiments advance the understanding of FCI suppression mechanisms and hopefully provide a technical foundation for engineering applications in nuclear safety.",
