NSUF 23-1910: Neutron Irradiation of Updated In-Pile Steady State, Extreme Temperature Experiment (INSET)

Material and sensor characterization at temperatures up to and exceeding 2000℃ in a radiation environment is limited. Advanced reactor designs that operate in this temperature range are limited by the materials and instrumentation able to survive in extreme environments. These next generation systems are further limited by costly and time-consuming testing at full scale. INSET has been designed to provide a rapid and inexpensive option for scalable, candidate material and sensor testing at high temperatures under neutron irradiation. This testbed has been updated with a new graphite heating element and internal structure, allowing for higher temperatures and larger samples than the previous iteration. While the new resistive heating element and larger specimen region within INSET will allow for the necessary rapid technology advancements, it must be validated first. Understanding the radiation environment and effects on the vehicle and its performance will inform future tests for material and instrumentation selection for advanced reactor development.
