Performance of visual inspection of reactor pressure vessel (RPV) and RPV internals is mandatory according to plant pre-service and in-service inspection programs.


Execution 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 (FOSAR).

 

Lifetime extension programs will demand additional inspection scope to be performed.


SUSI is a multi-purpose device for underwater visual inspection of various reactor areas and additional applications.

 

Visual inspection of:

  • RPV
  • RPV internals
  • Main coolant pumps
  • Reactor coolant lines and other piping
  • Pressurizer, accumulators and tanks (primary and secondary side)
  • Steam generators (primary and secondary side)

 

Other applications:

  • Core mapping (verification)
  • Observation of underwater component handling
  • FOSAR

 

Visual inspection of RPV and RPV internals using SUSI is performed by our highly qualified and experienced inspection personnel certified according to DIN EN ISO 9712 and ASNT / ANSI CP-189.

 

The universally applicable multi-purpose equipment family allows flexible use based on customer needs.
