Advanced reactor technologies have generated interest for their potential to reduce fossil fuel emissions, improve energy efficiency and cut down on nuclear waste. We have designed, constructed , and operated a specialized test facility to measure hydraulic parameters and validate computational tools used in reactor design and testing. The fast reactor assembly design used is significant, not only because of the complex inner knowledge it can provide about advanced reactors, but also because the Texas A&M experiment is using the largest transparent test fuel assembly of its kind to date.
Measurements of axial and azimuthal pressure drops, and velocity fields are collected and analyzed used the state-of-the-art instrumentation and advanced techniques.
New experiments are being conducted to investigate the flow behavior at different locations in the bundle. New advance techniques of flow visualization are being explored. The new activity is sponsored by the Nuclear Energy University Program (NEUP), under the project DE-NE0008652
