Zittau Flow Tray

The geometry and dimensions of a simplified sump model were scaled up on the basis of a generic PWR according to german PWR conditions. Upstream generic PWR sump data in front of the sump strainer were selected on the following basis:

  • Original dimension of the generic reactor sump height up to 3.0 m
  • Original flow path length for the time taken to transport the debris from the break location to the sump strainer up to 5.5 m
  • Simplified rectangular flow cross section in the upstream region without obstacles
  • Volume dependent scaling of sump strainer surface area (superficial velocity), pump volume flow
  • Stable fluid temperatures up to 70°C
  • Chemical resistant materials like stainless steel and acrylic glass
