Provide the means to measure critical safety performance parameters for a variety of experiments by developing and qualifying sensors and other in-pile instrument technologies.
Advanced instrumentation is key to unraveling the complex multiphysics involved during transient irradiation experiments. This includes development and validation of modern modeling and simulation tools. A science-based, engineering focus for nuclear fuels and materials development requires access to data streams beyond those that have historically been available. Successful development of advanced fuels and materials hinges on well-coordinated and innovative instrument R&D.
The TREAT facility provides a flexible environment for development and qualification of instruments used in in-pile transient testing. Using a science-based approach capitalizing on modern modeling tools, theory, and experimentation, researchers are performing R&D to establish a selection of instrumentation technologies with defined measurement output uncertainties. In particular, the instrumentation R&D group at the High Temperature Test Laboratory at INL provides expertise and key facilities (e.g. furnaces, coolant environments, etc.) that support measurements in experiments at the TREAT facility.
