Welcome to the Unpopular Opinion community!

How voting works:

Vote the opposite of the norm.

If you agree that the opinion is unpopular give it an arrow up. If it's something that's widely accepted, give it an arrow down.

Guidelines:

Tag your post, if possible (not required)

If your post is a "General" unpopular opinion, start the subject with [GENERAL].
If it is a Lemmy-specific unpopular opinion, start it with [LEMMY].

Rules:

1. NO POLITICS

Politics is everywhere. Let's make this about [general] and [lemmy] - specific topics, and keep politics out of it.

2. Be civil.

Disagreements happen, but that doesn’t provide the right to personally attack others. No racism/sexism/bigotry. Please also refrain from gatekeeping others' opinions.

3. No bots, spam or self-promotion.

Only approved bots, which follow the guidelines for bots set by the instance, are allowed.

4. Shitposts and memes are allowed but...

Only until they prove to be a problem. They can and will be removed at moderator discretion.

5. No trolling.

This shouldn't need an explanation. If your post or comment is made just to get a rise with no real value, it will be removed. You do this too often, you will get a vacation to touch grass, away from this community for 1 or more days. Repeat offenses will result in a perma-ban.

Instance-wide rules always apply. https://legal.lemmy.world/tos/

You can't claim to be an environmentalist and be anti-nuclear energy at the same time (lemmy.world)

[...] react very quickly to increased demand. You categorically cannot do that with nuclear, where did you learn this?

This is not correct.

A Brief Survey of Load-Following Capabilities in Modern Nuclear Power Plants

Load-following NPPs in France claim power output ramps as much as 5%/min if necessary, though typical ramps are kept below 1.5%/min.

Certain French NPPs routinely decrease power output 50% at night.

It's true that load-following is mostly not done with nuclear in the US, but this is policy/common practice/habit, not a technical limitation of nuclear power plants.

Also, I mentioned pumped hydro storage to point out specifically that battery technology really isn't effective enough yet. It still doesn't scale well, it's too expensive for large grids.

thanks for sharing this!

hilarious to see the other guy doubling down even after you cited an actual source.

This is not correct.

It is, you just proved it yourself:

"typical ramps are kept below 1.5%/min."

Compare that with batteries or pumped hydro.

That's plenty fast enough for a power grid.

1.5% of 900MW is 13.5MW. That's plenty of power output scaling per minute.

I think you're getting peaker plants, e.g gas fired confused with load following.

Nuclear plants are not used as peaker plants. you incorrectly stated that they are.

It's a shame that you're being voted down here, even though your points are actually more on the factual side. Well, that's probably the fate of those who "dare" to say something against nuclear. Even if everyone else demonstrably doesn't have a clue about the subject: They're still bashing it. It's just good that downvotes on Lemmy don't really matter.
