Small nuclear plants are actually something that can possibly help (differently from the large ones). But I doubt anybody will get the costs down enough to make them viable, wind and solar are power horses. It's like creating a non-mainstream computer architecture at the 90's and early 00's, it won't improve fast enough to even match their speed.
About emissions, coal is responsible for a huge share of emissions on electricity generation. If you replace half of it with a 0 emissions source, and the other half a source 4 times more carbon efficient, it does go a long way to help. If we are luck, this will give us enough time to develop batteries, because that is very likely what will happen.
