Robotic Tank Refurbishment System (TRS) for U.S. Naval Vessels - 18395

A remotely-operated Tank Refurbishment System (TRS) has been developed to reduce the personnel hazards associated with manual refurbishment of U.S. Naval vessel tanks. This system is capable of using a variety of tools to complete the necessary refurbishment tasks within the tanks. In 2017, the design for this system was completed, and preliminary testing was successfully completed. (authors)

Hanford Double Shell Tank Integrity Inspection - Integration of Customized Robotics - 18400

28 steel, double-shell, million gallon waste storage tanks located at the Hanford site in Washington State store both radioactive and hazardous waste. To monitor their condition and ensure continued viability, these tanks are inspected periodically through a comprehensive integrity program. In 2012, the first leak in a double-shell tank at Hanford was discovered in the 241-AY tank farm (Tank AY-102) and the failure was observed to be from the primary tank bottom. However, the exact failure location and damage mechanism have not been determined. A decision was made to pursue the capability to inspect the primary tank bottom region in order to provide additional tank integrity information. This work is particularly challenging due to the confined space in the double-shell tank annulus region (i.e. the 30 inch space between the primary and secondary tank shells), the limited dimensions of the tank risers that provide access to the annulus space (risers as small as 10 inches in diameter), and also the very small dimensions of the air channels in the concrete refractory pad that the primary waste storage tank rests on (channels are approximately two inches in diameter). Veolia Nuclear Solutions, along with Key Subcontractor Inuktun, were contracted to provide the capability to conduct these tank inspections in support of Hanford's double-shell tank integrity program. The Veolia Nuclear Solutions /Inuktun team designed, built, tested and delivered a tethered miniature robotic crawler system that utilizes the marsupial approach - a larger deployment crawler positions a smaller inspection crawler. The deployment crawler is installed via the tank riser, is magnetically coupled to the side of the tank shell, and drives to the selected deployment location at the end of one of the refractory channels where the small inspection robot is subsequently deployed. Operation of the equipment is controlled from a trailer outside the tank farm (a distance of several hundred feet). The system design includes a custom mechanism that provides for positioning and cable handling as well as the controls interface (laptop connected via control cables). The solution leveraged the Veolia Nuclear Solutions/Inuktun team's experience with delivering similar modular systems for other US and international sites. This simple but innovative solution delivered on an accelerated project schedule underlines the ability to provide effective robotic solutions to the nuclear industry. (authors)

Remote Handling Approach for Whiteshell Laboratories Standpipe and Bunker Legacy Waste Retrieval - 18417

Veolia Nuclear Solutions (VNS) has been contracted by Canadian Nuclear Laboratories (CNL) to design and delivery a system to retrieve and repackage legacy waste on-site. The waste has a variety of forms and conditions and requires a flexible and robust set of remote handling devices to complete the task. The focus of this paper is to highlight the remote handling philosophy being used on the project which can be applicable to other projects. This approach is based on past experience and uses a range of remote handling devices and techniques matched to the variety of tasks in the project. (authors)
