Pacific Northwest National Laboratory (PNNL), in collaboration with Idaho National Laboratory, proposes to design an ultrasonic sensor and associated instrumentation for irradiation testing and deployment at the Transient Reactor Test Facility (TREAT) in support of transient testing of fresh and pre-irradiated nuclear fuel samples. The ultrasonic sensor will provide a new measurement capability for use in the TREAT facility for in-situ characterization of fuel pin deformation.
