W28 Thermal-Hydraulic and Severe Accident Research

The session will focus on the NRC’s efforts to address current issues in the thermal-hydraulics and severe accident arenas, including experimental and analytical tool development programs. It will discuss, in particular, the following topics:

  • the NRC’s use of computational fluid dynamics codes
  • Symbolic Nuclear Analysis Package (SNAP), the graphic user interface to TRAC/RELAP Advanced Computational Engine (TRACE) and Methods for Estimation of Leakages and Consequences of Releases (MELCOR)
  • new SNAP uncertainty analysis capabilities
  • the NRC’s TRACE-Purdue Advanced Reactor Core Simulator (PARCS) code status and applications status
  • MELCOR, the severe accident code
