1 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Grant # 31310021M0003 Grantee: Texas A&M University - College Station Title of Grant: Assessment of TRACE Thermal-Hydraulic System Code for the Prediction of the Reactor Cavity Cooling System Behavior and Performance Period of Performance: 11/30/2020-11/29/2023 (FY2020 Notice of Funding Opportunity NOFO)
Executive Summary We will conduct a validation campaign using existing high-fidelity experimental data generated by the Water-Cooled RCCS (WRCCS) experimental facility at Texas A&M University, with the ultimate goal of assessing and demonstrating the capabilities of TRACE to simulate the relevant RCCS phenomena during normal conditions (steady state) and accident scenarios. We will develop a faithful WRCCS TRACE model and apply innovative modeling techniques to account for the complex heat transfer mechanisms between the reactor vessel, cooling panel, and secondary system.
Impact The project will increase the predictive capability maturity, and the overall TRACE code readiness.
The assessment will serve numerous advanced non-LWR technologies where the RCCS is considered as a safety system.
The experimental data that will be included in the project are essential for the validation of other thermal-hydraulic codes included in the BlueCRAB code suite for non-LWRs.
