We have designed and/or built many custom tools for underwater applications. Most of our applications have been in reactor internal modifications and fuel pool work. For decommissioning work we have modified some of our repair tools for destructive work.


 

We can supply tools that utilize the following processes:

• Milling for Core Barrel modification, Thermal Shield removal and repair, and many Reactor Internals Modification projects.
• Electrical Discharge Machining (EDM) for retrieving metal samples, fuel pin repair, component modification, and general chip-less machining.
• Metal Disintegration Machining (MDM) for fuel pool re-racks, destructive cutting, bolt removal, stuck studs, thermal shield removal, split-pin removal, decommissioning work, and general chip-less machining.
• Plasma Arc Cutting (PAC) for modifications of large stainless components and decommissioning work.
• Abrasive Water Jet (AWJ) for component removal and decommissioning. This process has some underwater limitations but can be used effectively in the correct applications.
• Camera systems used for weld inspection, monitoring a process, overview of a machine, pipe inspection, crack location and sizing, internals inspction, vessel head inspction and repair, and many other applications. We have a teaming partner that is a manufacturer of Remote Operated Vehicles (ROV) that can be used in fuel pools for inspection and other uses.
