Nuclear and Renewables

Yeah, nuclear is not really my expertise, but I thought that I might comment on all the online " debate" over whether the grid should be powered by nuclear, wind solar battery, fossil generation, or grid demand managaement,and what mix of these. Proponents of these positions are usually inflexible, and I frequently get the feeling that they omit facts in order try and make their case. I have questions... so let's start with Nuclear. One of the issues that I've heard with nuclear is that it is unable to ramp output up and down fast enough to respond to wind and solar variablity. That job ususally is done by natural gas generation. Not much info to be found on this subject, but I did find this post on thirdway.org saying no problem ! I found another one from Germany that wasn't so sure.
Next question What happens when things go wrong? As covered by this post on Twitter.
And what about those small nuclear reactors that I keep hearing about? proponents claim saftey issues and ramping issues can be addressed by these, But how small can they be ? Can i install one at the farm and and get electricity, and maybe free heat for the house and a pool? Just spit balling here. Could I sell any excess power to the grid for a fair price? If a sfety issue rose, it seems like it would be easier to remove a tiny reactor than a utility scale one. I'm well documented on my support of and belief in distributed energy. So here I'll mention Mr. Shellenburger, whose hard core endorsement of nuclear only seems to advocate for centralized nuclear generation. Really now, how small can these things be made? And it would be interesting if he would address my security concerns with an overcentralized grid (apologies if he has done that). And in the link above he also is dissappointed on dependence on imported energy. I truley don't understand stopping natural gas production in Europe either, until other options are ready.but as for german reluctance on using nuclear,I remember reading that Germany recieved some fallout from the chernobyldisater years ago. Hmmm, can't find it currently . Sorry about the snarky ness, but maybe these questions should be answered. Oh and I'll probably be devoting some time asking some questions to proponents of the demand management, wind - solar , Fossil folks as well. I know that not many people seem to read blogs anymore, So I'm probably at the "tldr" length so I'll call it a day. If you have any comments or useful info on my questions above I'll probably include them if you aren't bugging me about investment schemes...
