Abstract: Described herein are methods and systems for improved inspection, measurements, monitoring, and tracking of equipment installed underwater. They include structures or equipment installed in a nuclear reactor and fuel storage pools. This includes, but is not limited to an entire nuclear reactor pool, an entire nuclear reactor, fuel assemblies, fuel assembly identification numbers, core barrels, core plates, lower internals, upper internals, fuel transfer systems, alignment pins, baffle walls, former baffle assemblies, vessels, instrument ports, coolant tubes, spent fuel pools, dry cask storage areas, weir gates, steam dryers, steam separators, top guides, jet pumps, inside and outside of pipes, and weld seams. The described methods and devices increase the performance and integrity of the inspection and measurements during nuclear refuel, inspection or outage activities. The described methods and devices utilize one or more non-touch underwater optical system (including laser systems) for underwater equipment inspection, measurements, maintenance, monitoring, tracking and servicing.
