I’ll be a source. I worked at Calvert Cliffs Nuclear Power Plant in MD for over 10 years. Because of the trend of shutting down nuclear, I shifted over to operating a combined cycle power plant. Calvert with 2 units did about 1800MW combined, base loaded 24/7 except for outages, and those were staggered so that when one went down for maintenance and refueling, the other unit was still throwing 900MW to the grid. My current plant has 2 gas engine turbines and 1 STG, and on a good day when we’re fully up 2x1 with ducts in, we can hit about 800MW when it’s called for. Balls to the wall in perfect conditions on a plant that’s not even ten years old, we can’t do half of what Calvert was doing and they’ve been operating since the 70s.
Imagine what modern nuclear tech could do. We should’ve been a step ahead of everybody with this.
Do you have any opinions on light water SMR designs? Do you think the idea to mass produce them and distribute these smaller reactors on a local basis is feasible, or do you think if they are mass produced we would be more likely to see them clustered in series in more modern plants?
Idk much about that in particular but I can speculate based on what I know about the power industry and business in general. I think larger modular clusters (10-30) would be more common just because of the infrastructure needed. Sure, we might see instances of 1-3 units here and there, but I imagine that if a company is already going to the trouble of buying a plot of land and building a switchyard, getting water access and RO-EDI tech for it, cooling water of whatever type, n+1 redundancy on all equipment, radioactive waste management including on-site storage of spent fuel, etc while also welcoming the NRC and FERC and whoever else to scrutinize, it makes the most sense to have several units making money power. Like anything else, upping the scale makes the cost per instance go down. Nuclear in the US has a fuckload of red tape and permitting and oversight that cost a lot of money to stay on top of. There could be good applications for small clusters like closer to urban, more densely populated areas where land is expensive and the power needs are the immediate vicinity. Or in developing areas that don’t have much power demand, at least not yet. There’s no good reason why a small cluster couldn’t replace the remaining coal plants. It’s also completely feasible to throw some up at military bases or large university campuses for training and their own power needs. Big power will want to squeeze as many into as small of a space with as little maintenance requirement as they can get away with because everything they do is in the name of maximizing profits for shareholders. But for nationalized power like in France, it kinda doesn’t make sense to build anything else right now.
Maybe the best part of SMR tech as I understand it is that somebody could get the land and permits and infrastructure set up for the end goal but just build a small percentage of the reactors at first, and then scale up later. This is cheaper to start, faster to build, and is a perfect proof of concept strategy to get investors excited at funding the bulk of the project.
Thanks for this. I did ask OP for sources, in other words links to verifiable data to back up the assertion that:
“Has anyone who wants to “go green” without nuclear ever looked at the power output of these things?? It’s not even the same league! AaagggghHhHhhhhhhhh”
It’s the difference between spending 0 seconds looking it up and wanting “a source”, versus actually looking it up and not finding anything, then asking where the info comes from.
Asking for a source just to ask for a source is called sealioning.
Asking for a source just to ask for a source is called sealioning.
Good grief, no.
I read so much absolute bullshit around nuclear and renewables where people just write out their feelings on the subject. Asking for sources to back up their claims isn’t sealioning, it’s a polite way of asking someone to try and back up their claims with facts.
In this instance, OP said, “Has anyone who wants to “go green” without nuclear ever looked at the power output of these things?? It’s not even the same league! AaagggghHhHhhhhhhhh”
I want to know what they’re talking about. If they’re saying 1 solar panel or wind turbine has a smaller output than a nuclear plant then … well yeah, that’s obvious. If they’re saying renewables won’t work without nuclear then that’s a straight up lie and I’d like them to post sources to back up that assertion.
We could have had an unrivaled nuclear power infrastructure but those NIMBY assholes stopped it 50 years ago
now we rely on extending existing plants past their lifetimes
Running in fucking circles about how to save the planet.
Has anyone who wants to “go green” without nuclear ever looked at the power output of these things?? It’s not even the same league
So which part do you know to be false, that you couldn’t easily look up and had to ask him where he got this obscure info? Which part do you want him to source? All of it? Even the part where we are running in circles fixing climate change? Or is it the part where current plants are being showered in money to make up for extended lifetimes?
OPG manages power production for all of Ontario, with 2 nuke plants putting out over 3 GW each, for a total of ~6.5GW, OPG generates about 18-19GW so 30% is covered by two plants
The majority of the remainder is hydro across 66 fucking plants. And nothing else comes even close in output
And these are CANDU reactors, they don’t require refined uranium, and don’t contribute to proliferation like other plants, they also don’t meltdown explosively since boiling the coolant reduces the nuclear reaction rate.
So this kind of got lost in the weeds, and I see the argument below. The real reason I wont provide sources is partly because it is very easy to look up, and the reality is I could write a thesis with a ton of fucking sources and never cover it all. Typically, in an actual scientific debate, the onus is on you to provide a source which debunks my claims. However, I can give a short summary with some general, but verifiable numbers. I did a quick search for all of this, and most of it is on wikipedia with sources listed.
The average American nuclear power plant provides about 800-1000MW of energy, and has a life time of about 35-40 years. The US has 88 of them, most of which have been running since the 70s. Their age means many should be considered for decommissioning soon, but since we haven’t been building new ones to replace them the old ones continue to be serviced while we seek alternatives.
America’s largest solar farm produces ~350MW, which is less than half of a nuclear plant. That’s actually pretty decent, but this is the high end of the scale for solar, and this output is only achievable in perfect conditions (weather, daytime, location). At night it produces nothing. So the major problem many solar / wind enthusiasts ignore when discussing this is what happens then? How do we store enough power to sustain a city, or something larger, through every night? Those mighty big batteries aren’t eco friendly either, since at the moment our best option is lithium. That may change soon but we can’t really move on maybe.
My point to start with was that we should have never stopped building nuclear - we could have pushed fossil fuel out ages ago, but lobbyists really fucked that. Solar is great, but we need like 200 more of those major solar farms and an absolute fuckload of massive batteries, and the logistics of that is a nightmare that is unlikely to see fruition in time. It will be a long time before we have enough solar / wind to do more than supplement our power grid. We should keep building it in the meantime, but it is also a slow process, much like building nearly any large scale power generation.
To be clear, I am in favor of both. Nuclear should have always been the back bone of our power grid. Solar should be coming online as supplementary power supply allowing us to decentralize and support the transition to greener tech. This is not an either/or situation - we really need both, or fossil fuels will royally fuck our planet first. Maybe someday we will be efficient enough to go all solar, but expecting it to replace fossil fuels AND nuclear in the near future is just unrealistic idealism. We will die before hitting such ideal goals - in the meantime we must compromise.
Please provide valid sources to back up your comment. Thanks.

Here are the claims he made:

Right, you were just sealioning.
Re-read what I wrote, I was quite clear although I edited my post a minute after submitting so maybe you missed it.
You can claim I’m sealioning all you want, anyone with a functioning brain can see I’m not.
I don’t need to reread what you wrote, im not the one making the claims!
What you actually said to buddy was:
That message is the one you might want to edit instead of arguing with me it’s not sealioning.
Cool. We’re done here.
