Nuclear Fuel

Videoscopes are used for nuclear fuel inspections because they provide a non-destructive way of examining the fuel assemblies and their internal components. Nuclear fuel assemblies are extremely delicate and sensitive structures that are subject to a wide range of factors that can cause damage or degradation over time. These factors include radiation exposure, thermal cycling, mechanical stress, and more. Traditional inspection methods, such as disassembling the assemblies, can be time-consuming, expensive, and can pose potential safety hazards.

Videoscopes, on the other hand, allow inspectors to examine the internal components of fuel assemblies without disassembling them, reducing the risk of damage and exposure to radiation. They can be used to inspect for defects, such as cracks or corrosion, and to identify other potential issues that may compromise the safety or effectiveness of the fuel assemblies. By using videoscopes for inspections, nuclear fuel can be inspected more efficiently, safely, and cost-effectively.

INSPECTION EQUIPMENT FOR NUCLEAR POWER PLANT FUEL ASSEMBLY GRIDS

The examination of fuel assembly grids in nuclear power plants requires sophisticated and specialized equipment to ensure accurate and safe inspections. Remote visual inspection is a crucial component of this process, which involves utilizing a radiation-resistant probe designed to mimic the mechanical characteristics of a fuel rod.

This state-of-the-art inspection equipment is comprised of several components, including a durable and radiation-resistant quartz-technology fiberscopic probe that features a long length and can facilitate both axial and lateral viewing. The probe also incorporates distal LED lighting for optimal illumination during inspections.

In addition to the fiberscopic probe, the equipment features a waterproof PINCAM 900 endoscopic camera that is seamlessly integrated with an opto-electrical interface, allowing for easy connection to the proximal end of the probe. The entire system is supported by a 30-meter-long umbilical cable that provides flexibility and maneuverability during inspections.

To ensure the smooth operation of this equipment, it is typically paired with an advanced operating unit such as the TITAN, which offers precision control and real-time imaging capabilities to facilitate accurate and effective inspections of fuel assembly grids.
