New rig for studying SNF vibration integrity

摘要

During transportation, spent nuclear fuel experiences unique conditions and challenges to the cladding integrity as a result of the vibrational loading that is encountered during road or rail shipment. Understanding the role of pelletpellet and pellet-clad interactions is critical to characterising the fatigue response of zircaloy-4 cladding. However, until recently such data has not been available due to the lack of an effective testing system.
