Specialty Containers


Remote-handled Overpacks “ROP”

CTI worked with Department of Energy (DOE) to develop these containers called “remote-handled overpacks” or ROPs. The Transuranic Waste Processing Center in Oak Ridge, TN contracted with CTI to manufacture the first-of-a-kind containers. So far, CTI has manufactured and delivered thirty-three during 2015-2016 and another 66 units are in fabrication for delivery in 2017.

The ROP is specially designed to safely and securely store processed remote-handled transuranic wastes until it can be shipped for final disposal. The ROP includes layers of steel, concrete, and a thermoplastic inner liner, which is required to be water tight. After the ROP is closed, it is secured using steel bolts.

This is a great example of an innovative solution to a challenge that customers come back to CTI for every day.

Exelon Control Rod Drive Mechanism Container

May 2013 – Exelon, the largest owner and operator of nuclear plants in the U.S. and third largest in the world, selected Merrick & Company to provide management, design oversight / verification, shielding design, and fabrication oversight for two specialty container systems to be used during control rod drive mechanism replacement at the company’s Three Mile Island nuclear plant. The Merrick project team included Container Technologies Industries (CTI) to design and fabricate the container system at their Tennessee location.

The container was a single purpose system design constructed for transportation of new control rod drives into the reactor containment building. The second system was used for transportation of the old control rod drives. This unique design utilized a vertical removal approach and helped in decreasing the project timeline and cost significantly.

“Although space inside the X-326 Cess Building is still at a premium with components lining nearly every nook and cranny, major changes are taking place. During the past few weeks, the Non-destructive Assay (NOA) team has been measuring process gas coolers with a one-of-a-kind system that generates data faster than ever. Using the “blue box”;’ technicians measure the uranium inside the equipment before the components can be prepared for off-site disposal. The system works so well that they’ve already met the goal established for this fiscal year. Compared to other process gas equipment like converters and compressors, coolers are substantially smaller. However, they can be deceptively heavy; coolers on the floor weigh between 400 and 900 pounds. More than 1,000 coolers on the operating floor will eventually be measured and shipped off-site for disposal. When you first see the “blue box;’ it resembles a “Sealand” container because the box being used in the X-326 Process Building is actually two shipping containers that were cut in two and welded together as one large NDA measurement chamber. On the inside, the box features a high-density polyethylene lining to reduce the background radiation during measurements. It’s the quickest system they have to take measurements. Measurements can be taken in 15 minutes.”
