ok so i get what you're saying here.
But there is a fundamental thing with nuclear power, where the "burn up" of nuclear fuel doesnt change. In a submarine it doesn't matter because you're backed by a military force and you use 70-80% or 90+% enrichment, where as on land we have 3-5% upwards of 20% for the higher enrichment stuff these days i believe.
In the water its about safety and ensuring power production, on land it's about ensuring reliable and efficient power production. The only beneficial way of doing this is electricity storage. If you're nuclear reactor isn't producing power and has fuel, you are quite literally burning money. Think about it like diverting gas/coal input into a gas/coal fired power plant when power demands lower, as opposed to just lessening the consumption.
But yes it would be about 100% baseload first and foremost, everything else is a future concern, eliminate as much static load as you can and then deal with the rest in other manners.
Yeah I'm with you. I have a senior license at a US nuclear plant just for some background as I don't know yours. What I'm saying is that I can see value of multiple, say 300MW SMRs at a single site, that can go from 0-100% very quickly compared to current 900-1100MW reactors. So the idea would be you could have a plant in Mode 3 Hot Standby ready to raise power for peak loading. Ideally you'd have at least one reactor online at all times that provides its own in house loads and the standby in house loads that would be quite low. That is the value I see.
The issue at that point would be refueling and maintenance outages. It seems ideal that the design would need to support online refueling and enough loops/system availability to do the majority of plant maintenance online. In addition, the regulatory landscape has a lot of momentum to allowing plants to move to risk informed tech specs which allow for major equipment outages in modes of applicability. If the industry as a whole can agree on a handful of SMR designs with multiple capacity options, it really could be a stop gap to hopefully fingers crossed fusion power in, I don't know, 50-100 years from now? My two cents.
