Multi-purpose submarine inspection system SUSI-Gen3

Plants are constantly challenged when trying to examine hard-to-reach areas. Execution of inspections during outages on the critical path, where time pressure is an issue, calls for rapid performance without compromising precision and reliability. Time constraints also require efficient contingency tools for ad-hoc inspections or foreign object search and retrieval. SUSI is a multi-purpose submarine system for underwater visual inspection (VT-1 and VT-3) and NDE of various reactor areas, coolant lines, piping, spent fuel pools, tanks as well as steam generator primary and secondary sides. Specific add-ons for Foreign Object Search And Retrieval (FOSAR) extend the application range to support plant FME programs. The paper will give an overview on the present development and capabilities of SUSI-Gen3. Focus is on the new camera solution (HD camera, fully integrated high-rad tube camera) in combination with line and distance laser and the new control unit with different recording possibilities integrated.
