Abstract 

A liquid mercury target is used at Oak Ridge National Laboratory’s  Spallation Neutron Source (SNS) to generate neutrons. The mercury is flowing in a stainless steel containment vessel for neutron spallation, but also to cool the vessel itself. When the proton beam hits the target (1.4 MW at 60 Hz), the rapid rise in temperature causes an intense pressure wave that propagates in the mercury and into the vessel wall. In this presentation, the engineering workflow for the SNS target will be presented: mesh and simulation time requirements for the structural and fluid analysis will be explained in details.
