Electrical Material Characterization and Non-Destructive Diagnostics on Power Cable Dielectric Materials subjected to Thermal Aging – Phase III

Electric power is almost entirely transmitted through polymer insulated cables or wires in every home, factory, plant, or apparatus. If the temperature of a cable increases, it would be an indication that some accidents or malfunctions such as inflow of excess electric current occur in the cable. The generated heat, indeed, degrades the polymer insulations […]

Rare-earth element doping of dielectric thin films using ion implantation

The requirement for online communication continues to grow exponentially, primarily a result of the increased demand for information sharing bandwidth. This demand is driven by video-over-internet applications used for both entertainment, and conferencing (felt most recently in the need for remote working during the COVID-19 pandemic). Integrated optical components fabricated in silicon are receiving particular […]

Non-Contact condition monitoring system for outdoor ceramic insulators based on their radio frequency signatures

The research centers around the feasibility study of a method to detect faulty outdoor insulators and to classify the type of defects within the insulator. Every different type of defect results in a specific electromagnetic Signature that can be acquired using an antenna and oscilloscope. Using these Signatures some specific features (eg statistical or spectral […]

Investigation into the Radiation Damage Effect on Failure Mechanism of CANDU Spacer Material X-750 Ni-based Su

This study focus on the understanding of radiation-induced embrittlement in CANDU reactor spacer material, Inconel X-750. The helium pre-implantation following by proton irradiation will be employed as a surrogate for neutron irradiation to simulate the radiation damage on the microstructure of Inconel X-750. Micro-tensile test on irradiation X-750 material will be carried out to evaluate […]

Advanced Characterization of Zirconium Hydrides in Zr-2.5Nb Pressure Tube in CANDU Reactors

In the operation of CANDU reactors, the Zr-2.5Nb pressure tubes holding the cooling water and fuel bundles are susceptible to hydride cracking-induced crack initiation mechanisms, known as delayed hydride cracking and overload crack initiation. For structural integrity evaluation of CANDU pressure tubes, of fracture toughness and hydride crack initiation models were developed. However, the hydride […]
