Assessment of the Drift‐Flux Parameter Correlations Implemented in the Nuclear Thermal‐Hydraulic Analysis Code TRACE

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The present study assessed the drift‐flux parameter correlations implemented in the TRACE code, the flagship thermal‐hydraulic analysis code developed by the United States Nuclear Regulatory Commission (US NRC). The code is architected on the basis of a two‐fluid model.

Experimental study of bubble flow behavior during flow instability under uniform and non-uniform transverse heat distribution

Nuclear Engineering and Technology, 2020
Experiments are conducted to study bubble flow behavior during the instability of subcooled boiling under uniform and non-uniform transverse heating. The non-uniform heat distribution introduces non-uniform bubble generation and condensation rates on the

Inverse Uncertainty Quantification using the Modular Bayesian Approach based on Gaussian Process, Part 2: Application to TRACE

, 2018
Inverse Uncertainty Quantification (UQ) is a process to quantify the uncertainties in random input parameters while achieving consistency between code simulations and physical observations. In this paper, we performed inverse UQ using an improved modular
