Whenever I ride around Berkeley, CA I see a sea of "nuclear-free zone" signs on roads filled with Prius traffic. It's not so easy to understand the real agendas here.
The real agenda has a lot more to do with impressing your neighbors with how eco-conscious you are (ideally via cheap signals like signs and bumper stickers) than it does with costly and difficult initiatives like figuring out how to meet the world's energy requirements in a sustainable way.
How have you decided you can speak for all prius owners? If people ARE trying to "keep up with the Joneses" by buying priuses instead of SUVs and Corvettes that would be a great agenda.
This tired bullshit again?
Yes, we understand that everyone could be doing more to help some cause, and that some people care more about appearances than improving the world, and some people do legitimately good deeds for ‘selfish’ reasons like increased self-esteem.
The “virtue-signaling” “every decent action in the world is done just to impress one’s tribe” meme is getting old.
What action are you taking to demonstrably promote the reduction of virtue-signaling?
It seems like much of the calling out of alleged virtue-signaling is virtue-signaling itself.
Saying "We should treat the environment better" while being honest about your own [lack of] contribution is perfectly fine.
By the same token, I can complain about a group, and as long as I don't claim that my complaints magically fixed the problem, that's fine.
That's not at all how people use it colloquially.
Nobody is claiming that bumper stickers, Priuses, statements of "thoughts and prayers," or changing one's Facebook profile picture magically fix any problem. And yet those are the exact things that get labeled virtue-signalling.
In this thread alone, jaredhansen mentions "ideally via cheap signals like signs and bumper stickers" - though admittedly doesn't say virtue signals. x220's definition is also at odds with yours. https://hn.algolia.com/?query=virtue-signalling is rife with examples.
The incessant cries of virtue-signalling on the web absolutely do not require someone claiming that they've "magically fixed" any problem, and are almost entirely gate-keeping, goalpost-moving, ad hominem attacks, simple partisanship, and general lazy argumentation.
A bumper sticker signals "I care".
A prius, in theory, signals "I am actively helping, a lot".
They're both kinds of "virtue signalling", but they're very different in scope.
The 'maddening' thing is not when people signal they care a little bit. It's when people signal they care a lot, but their actions contradict that.
The reason why more plants aren't being built is because they are not cost effective compared to other options. You can argue that maybe the government or whoever could do more research to change this, but every company that wants a nuclear plant in the U.S. has one already. Until the engineering and regulatory situation changes so that it's easier to build a nuclear plant than it is to build a solar one, they're going to keep building the latter instead of the former.
They are a company to pay attention to IMHO.
Worrying about nuclear waste at the beginning of the nuclear age when most of that waste is actually valuable fuel is downright idiotic.
If you're comfortable eating food grown in the soil grown around uranium processing plants then by all means go ahead.
You do realize we can detect contamination by radioactive elements in quatities many orders of magnitude lower than could conceivably cause any harm right?
On the other hand, I live in Europe and our local government has yet to produce a complete environment monitoring fail such as the Flint incident in the USA.
Nope. I always keep my phone in airplane mode when I'm not using it.
You vote for Jill Stein.
You should be more worried about wearing sunscreen every day than the amount of energy you get from any wireless antenna. The sun puts out vastly more electromagnetic radiation than any wireless device ever will per cubic foot/meter/whatever.

Soon it will be possible to use most of the waste as fuel: "...Fast reactors can "burn" long lasting nuclear transuranic waste (TRU) waste components (actinides: reactor-grade plutonium and minor actinides), turning liabilities into assets. Another major waste component, fission products (FP), would stabilize at a lower level of radioactivity than the original natural uranium ore it was attained from in two to four centuries, rather than tens of thousands of years"

While there are issues with nuclear power, the worry people have about nuclear waste is greatly overblown to say the least. The amounts generated are manageable and in a relatively short amount of time we can use most of this "waste" to generate electricity. (The same can't be said for coal waste - like just about everything else associated with burning coal, coal waste is an environmental diaster.)
Well, it's not, and there doesn't seem to be much focus by the DoE to do so. Therefore storage of waste is still a major problem if you want to generate electricity with nuclear power plants in the US.
The politics around nuclear waste are preventing the construction of reactor designs which exist today which could take waste that exists today and use it with an output with a much more manageable half-life than the waste we have just sitting around right now.
Right... The only technical problem, how to store waste indefinitely, is only a problem because there's a larger political problem that prevents the waste from being recycled/reused. Since the political problem is highly unlikely to be resolved within a few decades, that leaves us with the technical problem of how to deal with the waste as we are currently generating/storing it.
The is a great place that has been identified, tested and evaluated in the US. Most experts agree that it is a site that would work perfectly fine.
But guess what, its insane political battles that stopped this from being used and that is still the case.
Even so, without a end solution, there is no problem with storing it in a different place for a couple 100 years as it has a tiny volume.
Personally I don't think this is the biggest problem with nuclear power, and it's certainly not in and of itself a reason to switch to alternatives. But it's not an issue to ignore either.

Why don’t we? Politics and the lack of military uses.
As opposed to all those military uses of dams and wind turbines. Right. And of course, I wonder what the fuss is all about with Iran, then...
The reason nuclear is in decline is the track record of spectacular disasters: Three Mile, Chernobyl, and now Fukushima. Get at least a generation without massive failures, and people might be willing to give nuclear a chance; but there have been 3 in my lifetime alone!
(Plus, in any country not as big and isolated as the US, any plant is a massive weakness from a defense perspective...)
Nuclear is nowhere close to that over the past half century of use, even if you toss in fatalities caused by nuclear weapons, which is a whole different category.
Realistically, installation of solar and wind is actually more dangerous than Nuclear, because of falls.
Also the fact that we use uranium instead of the safer and more abundant thorium is because you can’t make thorium bombs.
The reactors that have failed are these military derivative designs that lack safety features because there is no space for them in a submarine. No modern design has had such a failure, or could have such a failure since they have no reliance on active cooling and have safeguards to structurally prevent a core meltdown.
Nuclear has its issues, but everything else does too.
Zero? How many people have died making manufacturing computers, tvs, toys, or appliances; all of which have all the same heavy metals as solar panels by virtue of being electronic goods? This is essentially FUD. A single PV panel can generate 5-10 Mwh over its service life, conservatively. On the low end that is equivalent to about 2 tons of coal. Since coal contains a broad cross section of heavy metals and they become more bioavailable when burned, I think you're better off with the panels.
It has little to do with nuclear waste for civilian use today and is in no way comparable to civilian nuclear waste and how it is stored.
Also, Fukushima is the exception of the exception, it is a bit of land that can not be used for long while its not a lot of land and its in a nuclear exclusion zone anyway.
I don't want to ignore the issue, but I will just say that the amount of time, ink and energy spend on it is way out of proportion to how much it matters
People keep making the argument that climate change is a existential issue but then saw, well, nuclear is not a solution because of this nuclear waste problem. That is insane reasoning in my opinion.
There's a huge difference in nuclear going from a small chunk of our present day power generation to eras where some see it as being the primary generator for whatever exponential increases in energy we'll be using in the future. This change in scale really should affect how you look at things. Nuclear in particular has some pretty catastrophic fail scenarios, major decommissioning issues, and other problems. These can kind of be hand-waved away at current levels, but can't when you start talking about increasing operations on the order of magnitudes.
And when you start talking about things like this you're also implicitly alluding to breeder reactors, salt-water extraction, and other technologies that not only add substantial complexity (and side issues) but also greatly increase the costs relative to present day nuclear, which poses even more issues in terms of sustainability.
For all intents and purposes solar is pretty much a flawless method of energy production. The one issue is night time production, but there are countless ways to store energy even if we ignore more utopic scenarios like global high energy direct current lines constantly transiting energy to where it needs to go. Given the practically unlimited generation possibilities the loss of energy involved in either storage or transit are not really that big of a deal, and would not affect expected pricing the same way as dealing with nuclear's practical problems of scale will.
