Direct numerical simulation of turbulent natural convection in a heat generating fluid within a shallow horizontal enclosure

Core catchers are a significant safety feature of Generation-IV nuclear reactors for the safe dissipation of decay heat and maintaining the integrity of the reactor containment in the event of a severe accident. Direct numerical simulation is used to simulate turbulent natural co...

Experimental investigation of surface inclination effects on ablation of a solid impacted by a hot liquid jet

In sodium-cooled fast reactors (SFRs), the potential consequences of a severe accident with core meltdown are now considered during the reactor design phase. Such events lead to the formation of a corium , a radioactive mixture of molten nuclear fuel and structural materials. Two...

WEST advanced wall protection achievements toward long pulse operation

Abstract Long pulse operation in magnetic fusion devices requires well controlled plasma power exhaust to the divertor & wall, and avoidance of wall hot spots that could evolve in wall damage. At WEST, 10 major plasma facing components are monitored using 10 series of temperature...
