Thought I'd jump in here, I worked in both military and commercial nuclear power. Commercial nuclear power, at least in the U.S., is only limited in how fast they can change their power levels by design of the fuel, it is not an intrinsic limit in uranium fuel. Military reactors can and constantly do change their power levels at rates similar to other commercial but non-nuclear power plants.Now, let's jump over to nuclear power. What is the biggest downfall of nuclear in the power grid? It cannot be acelerated or throttled quickly. It is a good solid base load power generator, but cannot compensate for the peaks during the day. So, you would traditionally build nuclear to cover the minimum power requirements throughout the day, every day of the week, and rely on coal/gas/oil to cover the peaks throughout the day.
What is we instead built nuclear to the full value of the peaks?
You would end up with hours of the day where the nuclear plants are outputting all of this power, and it has nowhere to go. While we move to more EVs, we would expect the peaks and valleys to change some as people start charing millions of cars at home every evening, but it certainly wouldnot level things out completely. We would still have hours and hours of the day and weekends where the nuc plants are outputting more power than the grid needs.
What if…just supposing…during these off peak hours, we applied the extra electricity on the grid to electrohydrolis….of the hot cooling steam at the nuclear power plants?
You have now supplied electricity is the cleanest form we currrently can, with nuclear power, you have provided alternative transportable fuel sources, ala hydrogen and oxygen for fuel cells, and done it without incurring excess enviromental costs. You’ve also supplied all the power you need for increasing EVs
In other words, it's not that it can't be done, it's just the way current commercial fuels are designed.
You're right that the fuel currently in our commercial reactors is incapable of rapid power changes, but it is not an obstacle that couldn't be overcome.
The temperature of the steam coming out of those cooling towers is not going to be hot enough to be particularly useful. It's only around 100F, it's not particularly energetic, there's just a ton of it. The commercial plant I worked at turned about 30k gallons of river water to steam every minute at full power.
