NuVision Engineering, Inc. has provided radiological decontamination services to commercial nuclear and government facilities around the world for more than a decade.
Originally developed and implemented in the early 1990s, our decontamination system is a unique, virtually dust-free way to efficiently clean many types of surfaces including steel and concrete.
We have successfully implemented the process in a number of areas, including:
- Pipe-end decontamination for steam generator replacement projects
- Equipment, structural steel and concrete decontamination
- Radiological decontamination of pipe sectional nozzles prior to weld repair
Benefits of our decontamination system include:
- Little, if any, dust is generated during the blasting process, reducing the potential for airborne contamination
- Lightweight, portable equipment
- Equipment can be automated to reduce man-rem exposure
- Wide selection of abrasive blast medias to accommodate a variety of surface cleaning needs
- Rapid surface decontamination with minimal change to the surface profile
- Media can be recycled up to 5 times and may possibly be incinerated, further reducing waste
- Soft media can be compacted up to 6 to 1 ratio
- Dry blasting - no liquid waste to clean up
- High decontamination factors are achieved with a single blasting pass
