1 Computational Fluid Dynamics (CFD)
Validation Plan Risk Informed GSI-191 Resolution Texas A&M University July 26, 2011
2 Outline Risk Informed GSI-191 Purpose General Approach Description CFD Simulations Approach
3 Purpose Risk Informed GSI-191 To validate and assess the capabilities of CFD code on studying the debris transport and deposition in the reactor core.
To implement the model to be used for the Downstream Effect Analysis
4 General Approach Description Risk Informed GSI-191 Phase 1: Data Collection Detailed information about existing experimental activities conducted on fuel bundles will be collected. This will includes:
9 Geometry and dimensions of the experimental facility used (drawings).
This should include the tested fuel assembly type (e.g. 17x17 or others) and the spacers type.
9 Experimental procedure description.
9 Debris Preparation, Characterization, Quantities, Concentration, and Injection Method.
9 Boundary Conditions (flow rate, pressure, temperature).
9 Experimental Results (pressure, pressure drop, velocities, debris deposition).
Phase 2: Model Preparation and Testing The mesh of the given geometry will be constructed and mesh sensitivity studies will be performed.
Phase 3: Simulations and Results Analysis Simulation results will be compared with the experimental data in order to validate the model.
5 CFD Simulations Approach Risk Informed GSI-191 General Single Phase Flow Analysis.
Isothermal Conditions.
Discrete Phase Method (DPM) approach will be attempted to model the debris inside the reactor.
Software Candidates:
STAR-CCM+
Ansys CFD Modeling:
k-Shear Stress Transport (SST) Turbulence Model Porous Media to model grid spacers and core supports
