1 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Grant # 31310020M0005 Grantee: Texas A&M Engineering Experiment Station Title of Grant: Heat Transfer Experimental and Computational Data for Molten Salt Reactors Applications.
Period of Performance: 9/30/2020-9/29/2023 (FY20 Notice of Funding Opportunity NOFO)
Executive Summary We will generate high-fidelity heat transfer experimental and computational data to advance the predicting capabilities of existing and new heat transfer correlations for molten salt environments. The data will be generated under prototypical operating conditions, and for geometrical configurations of major interest for the molten salt reactor designs. Local effects, including solidification of the salt, and fouling of the surfaces will be studied. The data generated will ultimately fill the gaps in heat transfer data needs for Chloride molten salt reactors and advance the predictive capabilities of system-level computer codes included in the BlueCRAB codes suite.
Impact We will produce a unique high-fidelity experimental and computational heat transfer database for molten salt reactor applications.
The database will advance the predictive capabilities and reduce uncertainty of the prediction of heat transfer correlations for molten salt applications.
The database produced will support the increase of SAMs predictive capability maturity, and the overall code readiness, and support the validation advanced CFD codes (Nek5000 and Fluent)
Simulations and experimental results will become available for generation of reduced order models, for direct implementation into BlueCRAB specialized code SAM.
