Hibot and Vinçotte perform inspection of
bunkered tanks in a nuclear waste facility(Tokyo, Nov. 10th, 2023) Hibot Corp., an innovative robotics start-up and pioneer of the RaaS
(Robot as a Service) model for the inspection and maintenance of industrial infrastructure,
and Vinçotte, member of KIWA group, have successfully performed robotic inspection of
bunkered tanks of a nuclear waste facility in confined and hazardous spaces.

Vinçotte, member of KIWA group, was contracted
by Belgoprocess, a subsidiary of NIRAS (the BelgianNational Agency for Radioactive Waste and enriched
Fissile Material), for visual inspection and thickness
measurements of bunkered storage tanks on their
Site 2 wastewater processing facility. Due topresence of ionizing radiation and the risk ofradioactive contamination, it was decided to utilizea remote inspection technique.

Most of the storage tank is stainless steel, which precluded the use of magnetic crawlers.
Suction-based crawler robots and UAVs (drones) were deemed unsuitable due to the high riskof contamination in such environments. In addition, confined spaces around the tanks madeit impractical to use scaffolding.
Vinçotte relied on their robotics partner hibot to deliver Float Arm, an articulated robotic arm
developed for multipurpose NDT inspections. Float Arm was packaged against contaminationand fitted with the appropriate sensor payloads. In addition, a dedicated cage was developedand commissioned to provide the robot with access to the narrowest corners of the deep
bunkers using the existing overhead cranes. These are places that would otherwise remain
inaccessible to people or other inspection devices.

“Innovative ideas had a lot of weight in this tender,” says Frankie Vermierdt, project lead for
Belgoprocess. “The proposal to use a robot was new, but above all realistic and well thought
out.”

Results
No major preparations, such as building scaffolding or other general protective measures,
were required for the inspection. Thanks to Float Arm, the risk associated with working atgreat heights can be significantly reduced. Furthermore, the exposure of personnel to ionizing
radiation and the risk of radioactive contamination is kept to a minimum. In short: aninspection that meets all standards for industrial safety, occupational safety and health.
All measurements of the remote inspection performed with Float Arm were digitized andrelated to a coordinate system and point cloud.

“The fact that the request for such an important and challenging mission came right after
hibot and Vinçotte signed the collaboration agreement is evidence that there is a huge needfor automation of inspection works in confined and dangerous spaces”, mentioned Michele
Guarnieri, CEO of hibot. He added that “at hibot we were extremely happy with the goodresults achieved during this mission, and delighted to know that, thanks to Float Arm, nooperators had to be exposed to dangers. We are changing the way inspection is carried out,and making the world a safer place with robotics.”“The collaboration with Vinçotte went very smoothly, through all phases of the project. We
are very satisfied with the results of the Floatarm inspection,” Frankie concludes. “We arealready preparing for the next project and look forward to continuing our collaboration.”
