CASL: The Consortium for Advanced Simulation of Light Water ReactorsA DOE Energy Innovation Hub forModeling & Simulation of Nuclear Reactors
Task 1: Develop computer models that simulate nuclear powerplant operations, forming a “virtual reactor” for the predictivesimulation of light water reactors.Task 2: Use computer models to reduce capitaland operating costs per unit of energy, …… 5

• Local T&H conditions such as pressure, velocity, cross flow magnitude can be used to address challenge problems: oGTRF oFADoDebris flow and blockage• The design TH questions under normal operating and accident conditions such as:oLower plenum flow anomalyoCore inlet flow mal-distributionoPressure dropoTurbulence mixing coefficients
input to channel codeoLift forceoCross flow between fuel
assembliesoBypass flow
• The local low information can be used as boundary conditions for micro scale models.
