Stinger: Bridge-Free Tooling
The remotely operated Stinger tool provides BWR nuclear power plants the ability to clean and perform In-Vessel Visual Inspection (IVVI) functions during critical path activities, thereby reducing cost, radiation dose and critical outage time. Through advanced camera and remote positioning technology the system allows examiners to inspect from the annulus floor to the Reactor Pressure Vessel flange without tool removal or reconfiguration.
Remote operation of Stinger also allows for uninterrupted fuel movement and significant dose savings improvement by reducing the number of inspection workers from the refuel floor.
Stinger’s advanced visual inspection capabilities allow data to be transferred in real-time for analysis by qualified Level III inspectors at our IVVI Center of Excellence in Wilmington, North Carolina.
