2. 1. An experimental study on the dynamics of melt-water micro-interactions in a Vapor explosion

   Author : Roberta Concilio Hansson; Truc-Nam Dinh; Daniel Magallon; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik;

   Abstract : Vapor explosion as a result of Molten Fuel-Coolant Interactions (MFCI) postulated to occur in certain severe accident scenarios in a nuclear power plant presents a credible challenge on the plant containment integrity. Over the past several decades, a large body of literature has been accumulated on vapor explosion phenomenology and methods for assessment of the related risk. READ MORE

4. 2. An Experimental Study on the Dynamics of a Single Droplet Vapor Explosion

   Author : Roberta Concilio Hansson; Weimin Ma; Geroges Berthoud; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; steam explosions; radiography; melt preconditioning; noncondensable gas; Low energy physics; Lågenergifysik;

   Abstract : The present study aims to develop a mechanistic understanding of the thermal-hydraulic processes in a vapor explosion, which may occur in nuclear power plants during a hypothetical severe accident involving interactions of high-temperature corium melt and volatile coolant. Over the past several decades, a large body of literature has been accumulated on vapor explosion phenomenology and methods for assessment of the related risk. READ MORE
