Deploying cameras and sensors into legacy plant is often the only appropriate mechanism by which the current cell condition can be established. Each inspection requirement has its own access challenge with limited entry routes available. As well as the difficulty of getting equipment into the plant, care is required to ensure that it can be safely retrieved, even in the event of equipment failure. To address this requirement JFN specialises in the deployment and safe recovery of Plant Characterisation Systems.
Additionally JFN has the ability to deliver instrumentation packages to conduct integrity checks in-vessel, in-cell or even in-core. As well as camera inspections, systems have been designed for remote ultrasonic (UT) and eddy current (EC) non-destructive testing.

Radiation levels are not the only criteria preventing manual plant maintenance. It is often the case that access constraints force the client to consider remote systems. Typically systems include fault detection, surface preparation, the repair and final inspection.
