I also have a Nikon 8000 running on Win10 with Vuescan, Silverfast and NikonScan (it runs on Win10 if you have installed Silverfast on the same machine using the Silverfast drivers ) and never experienced that. Vuescan is by far my prefered software of the three.
There is a known banding (a regular pattern in shadow areas) problem with the 8000 you can get rid of using the Fine-Mode in Vuescan but this sort of banding has nothing to do with your shown example. I don’t think your banding problem is software-related.
One question, what was the scan-direction of the image? Did it go with the widest side into the scanner or in portrait orientation?
I ask this because a worn out or otherwise affected entry-mechanism can result in such banding. Had a similar issue with my other scanner. But this explanation only would apply if the image went in landscape orientation through the scanner. You would also see then, that the image is not really sharp when zoomed in.
Other (and more problematic) explanations would be a defective ccd or a firewire issue
On the other hand, what maybe speaks for a software related issue is, that some of the banding lines run over the Vuescan-Watermark, which is applied, when the scanning is done.
Maybe you can try different input resolutions (and also take care that for testing all LED RGB values are the same) and output formats. Did you attach a color profile to the output file?
On option you can also play with is the save option in vuescan. You can save the picture while scanning (line by line so to speak) or when the scanning is done
