We conduct large scale testing, demonstration, and validation at our facility in Mooresville, North Carolina. NuVision Engineering hosts comprehensive research and development in support of waste remediation system design, validation, demonstration, and acceptance testing of equipment prior to delivery. The 22,000 sq. ft. facility provides capabilities and infrastructure for simulant preparation and equipment assembly. We also do equipment testing for tank mixing, bulk waste/heel retrieval, tank decontamination, cementation/grouting development systems, robotic and remote applications. Our capabilities are supplemented by links with local laboratories to provide a full range of destructive and non-destructive testing and sample analysis services.
We have conducted over 100 large-scale demonstration projects in the US and UK, including waste retrieval and processing, decontamination, and decommissioning. These projects have been focused on both our own innovative technologies as well as those of third parties.
