Nuclear Energy Systems Transport (Nu-EST) Lab

Nu-EST lab performs computation and experimental studies to support advanced design of safe and economical nuclear power plants. This includes understanding thermo-fluid sciences including stratification (layers), natural convection (heat transport) and phase change. The laboratory uses advanced experimental techniques to observe these physical phenomenon under extreme condition such as high temperature, corrosive and oxidizing environments. This lab also develops thermal energy storage solutions for small-scale building or large-scale (gird) energy storage.

1. High temperature thermal-hydraulics

Nuclear grade graphite material has been shown to undergo oxidation and degradation during air intake. Using state-of-the-art technology, we are able to characterize and classify thermographic images of graphite surfaces during heat transfer experiments. With a better understanding of how the degradation takes place, we can help the industry to develop better methods in the future.

2. Thermal Energy Storage

The challenge facing existing nuclear power plants is their inability to keep up with peak-hour demand due to reactor safety limitation. We develop methods to store energy for use during these peak times. These methods are based on manipulating thermal anisotropies in materials at micro or macro-scale.

3. Passive Nuclear Safety

The performance of passive safety systems which remove heat are critical for enhancing safe nuclear energy in the world. We examine natural circulation in a two-phase flow design for the short term or long term passive decay heat removal.
