2. 1. 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

4. 2. On Fuel Coolant Interactions and Debris Coolability in Light Water Reactors

   Author : Sachin Thakre; Weimin Ma; Florian Fichot; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; severe accident; fuel-coolant interactions; melt jet fragmentation; steam explosion; debris bed coolability; uncertainty analysis; Energiteknik; Energy Technology;

   Abstract : During the case of a hypothetical severe accident in a light water reactor, core damage may occur and molten fuel may interact with water resulting in explosive interactions. A Fuel-Coolant Interactions (FCI) consists of many complex phenomena whose characteristics determine the energetics of the interactions. READ MORE
