Fuel Assembly Inspection System
The Fuel Assembly Inspection System (FAIS) speeds the inspection process up by three times compared to a single-camera system.
Inspections on spent fuel increase safety and, when done right, minimize outage downtime, resulting in cost savings for plant operators.
Diakont has developed the FAIS to maximize process efficiency; by assembling four D40 cameras with auxiliary high-power lighting in a ring-like shape.
High Efficiency Fuel Assembly Inspection
Installed during routine fuel transfers (refueling cavity to the spent fuel pool), the FAIS is placed in the transfer canal near the upender (in the spent fuel building). It is then positioned directly above the upender, with each camera oriented perpendicular to the four faces of the fuel assembly. The inspection begins once the fuel is extracted from the upender. There is zero impact (in added time or motion) on the fuel transfer operation.
High Quality and Reliability
One of the four D40 cameras is installed on a pan/tilt mount for remote manipulation and viewing on the bottom nozzle. The D40 camera system has won popularity among nuclear power plant builders, contractors, and operators worldwide, making it the ideal solution for fuel inspection applications. Thousands of systems have been deployed in the United States, Japan, France, Finland, and other countries.
