Show me a mass produced tiny reactor in production. If not in production, provide a solvent business that can produce and maintain these reactors.

"In comparison with nuclear, the amount of solar power built in 2016, taking into account how many hours each can operate each day, is the equivalent of more than 3 new nuclear plants.

To dive in a little deeper: let’s use a 25 percent capacity factor for new solar, making the 14,626 MW installed equivalent to 3,650 MW of theoretically perfectly running nuclear plants. The Westinghouse AP 1000 units under construction for the last 7-10+ years produce about 1,100 MW. So, in one year, solar additions were equal to what takes more than 7 years to build. The difference in speed of deployment is why UCS (Union of Concerned Scientists) is clear that nuclear power isn’t a near-term climate solution."

So if you're not going to take my (rando HN poster's) word for it, the Union of Concerned Scientists seems somewhat reputable.

Mass-produced tiny reactors exist in sci-fi, and maybe some potential long-term future. What we have now are ‘renewables’ so let’s be realistic.

And also US Navy submarines and large surface vessels.

Those are neither mass-produced, nor tiny - they produce 50-500MW of power.

The SG9 in the latest Virginia class submarines are only 30MW. As of 2001 The Navy has constructed over 235 nuclear reactors, with many more since. An average of >5 per year. For Nuclear reactors that is mass production.

Also because of the way the Navy works their reactors are less bespoke for each ship than traditional land based reactors - and better fit the mass production model. This is something that could scale.

And how are you going to grow a hyothetical "tiny nuclear reactor" buisiness faster than solar and wind are growing right now? By the time development is done, operating permits are sorted out and production is ramped up the idea will hardly be profitable, and certainly not nessesary anymore.

Nuclear power is simply too expensive.
