It can reliably detect voids in EB, but cannot provide information about material structure in the EB weld. After a brief introduction into modeling Lamb waves and UCA we focus on array processing techniques that enable estimating direction of arrival of multimodal Lamb waves. A common requirement for success of these approaches is the presence of a significant difference in ultrasonic responses from defects voids and weld clutter.

While passive acoustic emissions monitoring will likely have a role during the transportation of a fuel storage cask, the level of detailed information about the defect generating the event which can be ascertained from the detections in a complex structure remains for future work.

All of these studies concluded that the risks of the public receiving a dose above regulatory limits is very low. Due to self-shielding effects of the assemblies, a periodic pattern results and could potentially be used to identify Development of Ultrasonic Immersion Inspection Technique For Spent Fuel Canisters.

or severely degraded assemblies. Rough estimates of scanning times using an ideal detector array would be 1 week.

Proposed repair methods also require demonstration and compliance with an NRC-approved quality assurance program. In addition, the deep water above the stored fuel typically more than 20 feet above the top of the spent fuel rods would absorb the energy of debris that could fall into the pool. A licensee must first determine whether a particular system addresses the storage site's parameters, including analyses of potential earthquake intensity and tornado missiles. Dust and aerosols in the air being drawn though ventilation openings in the overpacks of passively ventilated dry canister storage systems may be deposited on the stainless-steel canister outer surfaces.

Based on these field tests and discussions about what would be of practical interest, the team as a whole decided a realistic goal was to detect catastrophic failure of a single fuel assembly, or one that was missing. This shorter licensing term means the casks are reviewed and inspected, and the NRC ensures the licensee has an adequate aging management program to maintain the facility.

One of the key findings is the ability to detect subsurface changes to the direction in which a crack is penetrating into the sample.
