The Goldfish is a manipulator designed for inspection of all large nozzles above the core. It is a submerged remotely operated vehicle combined with a scanner unit.
The Goldfish can be equipped with different NDE end- effectors as well as repair or machining tools.
The Goldfish was introduced in 2000 and has since then performed several inspections, both as a single unit and as a part of a triad of manipulators for vessel in-service inspections during a singe outage.
The Goldfish is a fast and reliable tool for inspections of in-vessel nozzles, does not require the use of service bridge, and allows parallel inspections and other activities in and around the reactor.
