> really, no waste at all, magic you say? The core problem with nuclear waste is that it's energetic. There are a number of designs that burn up waste; if we were building and testing them, poor reactor types could be abandoned and better ones could be improved. We're not doing that primarily because "nuclear" is a scary word owing to activist efforts decades ago. > This is just more of "Future Tech will solve this"…

> because "nuclear" is a scary word owing to activist efforts decades ago. Right, activists... not those pesky meltdowns spewing radioactive waste across Europe and into the pacific, it was the activists.

"spewing ... into the Pacific" actually dilutes it more than when it existed in ore in the first place. It had to be concentrated by orders of magnitude from ore, to make it radioactive enough to be fuel for a reactor. Before that, it was just backround that we've lived happily with for eons, and in the Pacific it is even lower level.

Meh, when major industry things fail, and e.g. a refinery just breaks and releases all of the oil and other stuff into the next best river, it will affect potentially millions of people's health if it's located right. That's why we're trying to make extra extra sure that it doesn't happen and hire experts, and learn from mistakes (and there were plenty, and I'm sure there will be more). "If this fails it's just too h…

It seems with Nuclear we have always underestimated the risk in the risk/reward nature.

I disagree, in fact, we have more frequently underestimated the reward. RTFA. As the article points out, tens of thousands of people die every year from lung disease directly related to fossil fuel combustion. Furthermore, he argues that more people have died from stress due to being relocated from Fukushima, than would have died if we left most of them in place. It’s the trolley problem writ large.

There is that old saw that generals fight the last war, and this article misses the modern risk of nuclear. With the development of cheap attack drones the risk of nuclear has increased over what is was. There is no effective way to completely protect against drones. Drones have already been used in an attack against a centralized energy facility. https://en.wikipedia.org/wiki/2019_Abqaiq%E2%80%93Khurais_at...

There was no increase of nuclear risk because of drones, and no need to increase the protection of the powerplants, for the very simple reason that there is nothing a drone can do against meters of reinforced concrete protecting the reactor. A drone big enough to do more than scratch the paint would be classified as a cruise missile, and that risk was understood since before the first nuclear powrplant was turned on.

> Waste was never really a problem and has been definitively solved. You bury it in a deep unmarked hole. Yeah, too bad it doesn't work in practice.

How does it not?

Not sure I've seen a HN post before where so many people in the comments have clearly not read the article. Not even the summary of key points right at the top. The piece is not anti-nuclear. Also, risk is not binary. Finding out the true risk of something does not mean it's high risk and therefore negative. You can assess the risk of something and conclude that the risk is low and generally overblown, which is the p…

Perhaps because you have to have a Medium account to read the article? I'd love to read it, but I don't love the idea of logging in to Medium to do so.

I'm anti-Nuclear (On Earth), but would prefer most people read it before commenting on it. So, I archived it.

I was also wondering like how the article says that relocating people near Chernobyl in such great extend isn't the right thing to do (taking the 9 months life expectancy limit in mind) but I am really confused here, because when I see movies or videos showing the Chernobyl accidents they show people feeling the burning sensation, vomiting, getting extremely sick and new babies being born with ill health, which is really scary. So if people don't re locate then they will constantly have this fear, right?

Hmm...Chernobyl pretty much was the worst case. And, like Fukushima, the impact of the reaction was much more severe than the impact of the radiation. [I looked at The WHO reports that were published every decade. Each one downgraded the estimated impact from radiation dramatically, whereas the health impact of the evacuation became more and more apparent].

Didn't they have to sacrifice some guys to cover some melted core in concrete to prevent much worse spread of radiation from happening? Or are you saying that didn't matter?

I think there needs to be real storage plans for radioactive water before terrestrial fission is a major power source but it is certainly telling that in 3 of those cases the radioactive waste was from fracking and not a reactor.

Recycling for spent fuels is a proven technology. Problem is ... it creates weapons grade Plutonium as the product, out of Depleted Uranium(stuffs so safe US military puts into tank shells as weights). You know, Plutonium is a highly toxic heavy metal, and a bit radioactive, so,

> Problem is ... it creates weapons grade Plutonium as the product, out of Depleted Uranium(stuffs so safe US military puts into tank shells as weights). Calling this the problem is just more fear mongering. The hard part about building a uranium-based bomb is getting weapons-grade uranium, because the bomb is simpler but U-235 is only 0.7% of natural uranium and is hard to separate from U-238 because they're chemica…

It sure makes an easy dirty bomb when stuck on a regular bomb though.
