More to the story....
A primary advantage of small, regional power sources is to reduce the losses inherent in long distance transmission. Any study of waste / power is only relevant by measuring power delivered, not power inserted into the grid.
According to world-nuclear.org, 90% of nuclear waste is low level -- typically things that are contaminated by radioactivity, such as clothing and tools -- vs spent fuel. An advantage of smaller reactors is less human maintenance, thus less low level waste. The article is only focused on intermediate (cladding, shields) and high level ( spent fuel ). These are certainly the most volatile, but it should be noted they are smaller in volume.
This sort of research is very valuable; we need to understand that, as usual, there is no silver bullet. That said, small reactors are one of our important weapons in weaning ourselves off our petroleum addiction before we over dose. Dealing with larger volumes of volatile nuclear waste must be seen as a form of penance.
