1 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Grant # 31310021M0050 Grantee: University of Texas at Arlington Title of Grant: High-Fidelity Experiments and Simulations of Heat Pipe Performance under Steady-State, Transient, and Accident Conditions Period of Performance: 9/28/2021-9/27/2024 (FY21 Notice of Funding Opportunity NOFO)
Executive Summary The objective of this proposal is to conduct high-fidelity experiments, modeling and simulations of Liquid Metal Heat Pipes for micro-reactor applications under steady-state, transient, and accident conditions. The data produced will support the validation of the specialized tools included in the Comprehensive Reactor Analysis Bundle (CRAB). We will produce unique sets of measurements of internal thermal-hydraulic parameters using advanced techniques, and measurements uncertainty will be quantified. The datasets produced will fill the known technology gaps can be directly used for the development of code closure models, and ultimately advance the predictive capabilities of Computational Fluid Dynamics (CFD) codes and system codes adopted for heat pipe reactors technologies.
Impact We will produce a unique high-fidelity experimental and computational database for liquid-metal heat pipes with uncertainty.
The database will support the validation and increase SAMs predictive capability maturity level, and other MOOSE-based tools.
The database will become available for validation of other specialized codes.
