Thanks for that term "symmetrical, on-demand power". Nuclear plants aren't very good for load following. The most responsive in the US are the Babcock and Wilcox plants because they use once through steam generators rather than U-tube steam generators like Westinghouse and Combustion plants. U-tube steam generators basically are slow responding and produce steam that's just at the saturation point - they use moisture separators to "dry " the steam. B&W steam generators are counterflow straight tube - primary coolant from the reactor comes in from the top and feedwater flows up from the bottom, so you by design have a region of superheated steam at the outlet to the turbine. That allows the turbine to be more responsive and have limited load following ability. It also means the steam generator has less inventory and can boil dry quickly like at Three Mile Island (B&W plant). Either case requires varying reactor power, and that's virtually not done - they run a near full power because maintaining the correct flux distribution is not a simple matter (unless things have changed a lot since I retired). It really leaves either fossil fueled or hydro plants for load following. If hydro plants are also used for river navigation and flood control, their response can be complicated, so it really gets back to something like NG plants for peaking.
Not in The West. Do the Russians get any credit for their contribution in ending WWII?Once the real story comes out regarding the depth of Ukraine corruption and criminality, will history view Russians as liberators?
Do you know anyone from Russia?Not in The West. Do the Russians get any credit for their contribution in ending WWII?
I was under the impression that people were making the mistake of confusing the Soviet Union with the Russian Federation and just were not sophisticated enough to make the distinction. But at this point, I just think that many in the West just hate Russians no matter what.
We are involved in Europe because of history. The last time we took that approach it didn't go so well and we ended up having to be involved anyway. We are involved in NATO as a deterrent. If America can't be trusted to abide by obligations then the dollar is no longer propped up and we lose the comfy way of life we've grown accustomed to.
My point is the world is intertwined. It's but as simple as America not being involved. As for tried being involved in but sure anywhere here is advocating for it. NATO, of which we are a member, is beefing up it's defenses as a deterrent in light of Russia military aggression.

Good Lord, canned response, should have known. Show your work...... Otherwise you're simply seeking sources to confirm your biases.
