Design Requirements for Ultrasonic Deformation Sensor for TREAT Experiments

Abstract

This report is meant to be a guiding document for the development of an ultrasonic deformation sensor to be deployed in TREAT transient experiments. As such, information detailing the reactor, likely experiment capsules, and facilities have been included. Also, information on the required measurement speed and resolution and design constraints have been documented through literature reviews and interactions with TREAT team leads. Development of this document has shown that although there are many potential applications, each with variations on design and needs, there are several basic constraints that need to be met for any application. The SETH capsule has been selected as a first target application, as it is planned for near term deployment, matches most of the design considerations of other planned capsules, and is designed to be used for sensor testing, along with fuel and material irradiations.
