Applications of ultrasounds in nuclear power plants including water detection in dry cask storage, defect detection in reactors, and health monitoring of radiation detectors.
This milestone report presents an update on the state-of-the-art review and research being conducted to identify key indicators of in-containment cable aging at nuclear power plants (NPPs), and devise in-situ measurement techniques that are sensitive …
Degradation of the cable jacket, electrical insulation, and other cable components of installed cables within nuclear power plants (NPPs) is known to occur as a function of age, temperature, radiation, and other environmental factors. System tests …
Computer modeling and simulation is becoming an essential tool for transducer design and insight into ultrasonic nondestructive evaluation (UT-NDE). As the popularity of simulation tools for UT-NDE increases, it becomes important to assess their …
This paper presents recent progress towards developing a prognostic health management framework for passive components of advanced reactors (AR). The focus of this paper is on lifecycle prognostics for passive components using a Bayesian prognostic …
This report describes research results to date in support of the integration and demonstration of diagnostics technologies for prototypical advanced reactor passive components (to establish condition indices for monitoring) with model-based …
The challenge in detecting crack under fastener heads (CUF) in a multi-layered aircraft structure poses the need for advanced NDE technology. Our previous work has presented the feasibility of eddy current (EC) technology using giant magnetoresistive …
Eddy current probes (EC) with Giant Magnetoresistive (GMR) sensors have recently emerged as a promising tool for rapid scanning of multilayer aircraft panels that helps detect cracks under fastener heads. However, analysis of GMR data is challenging …
The use of wireless sensor networks in structural health monitoring can significantly increase safety and reduce manufacturing and maintenance costs. Wireless sensor networks typically use low footprint smart active sensor nodes that are permanently …
