Inspection Systems
R.O.V. offers several standard Inspection Systems that perform a variety of tasks. All of R.O.V.'s Inspection Systems have been designed with time savings and radiological dose savings in mind. R.O.V. can customize inspection systems based on customer requirements.
PWR BMH Inspection System
Scarab IIIP Magnetic Crawler
The Scarab IIIP was designed to address an industry need to remotely inspect Pressurized Water Reactor (PWR) heads for evidence of boron deposits due to weld degradation. This inspection criterion became evident due to the discovery of a failed inconel alloy 600 nozzle weld joint discovered at a U.S. operating station, and the high susceptibility to primary water stress corrosion cracking (PWSCC). Initially, pole cameras were used to perform these inspections, however, operators received unacceptable levels of radiological dose during the operation.
The Scarab IIIP is a powerful, magnetic, wheel-driven crawler with a profile low enough to fit under a raised insulation package, and width narrow enough to maneuver the reactor head penetration rows. The crawler is equipped with a drive camera and a 400 degree rotational turret which incorporates a high resolution inspection camera and high intensity, adjustable lighting, all in a package measuring: 5.8 inches wide X 7.4 inches long X 2.7 inches high.
