Performance of visual inspections as well as other non-destructive examination (NDE) tasks are 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 effi cient contingency tools for ad-hoc inspections or search and retrieval of foreign objects (FOSAR).


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


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


Visual inspection (VT-1 and VT-3) of:

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


Other applications:

  • FOSAR
  • Ultrasonic inspections of core barrel and core baffle bolts
  • Observation of underwater component handling


Your Benefits

  • Time savings thanks to rapid and highly reliable performance
  • Universally applicable multi-purpose equipment family
  • FOSAR for safe operations
  • Highly experienced and certified personnel


References

Many customers request the availability of SUSI on-site for the entire duration of their outage to ensure it is ready to use for ad-hoc tasks without delay.
