Personally I think fission power's failure is a political and marketing one. I don't agree that the waste disposal issues, or the safety issues, are quite the big deal people make of them. (Not saying there are no unsolved issues, just that the issues that exist are not significantly worse than those present burning fossil fuels, and are better in some dimensions. They're just different, and in some ways very emotionally so.)

I think it might be fine that fusion power may be more expensive in some ways than fission, as long as its reputation is kept clean (figuratively and literally). Market fusion power as the savior of humanity, and get enough people to believe it, and it'll be fine.

> Personally I think fission power's failure is a political and marketing one.

I think it's because of the occasional catastrophic failures that spatter our short history with the technology. Fukushima made headline news around the world, leaked large amounts of caesium-137 into the ocean, caused a 20km evacuation radius, is projected to take a total of 30-40 years to clean up, and people think of it as not that bad of a nuclear incident.

In comparison burning fossil fuels is a classic tragedy of the commons problem. Way less sensational. You can do math and say nuclear has a safer track record than coal/oil. You can point to design, engineering or management faults with historical failures. It doesn't change the fact that nuclear had a very fair chance at being the future and shown itself to not be trustworthy. If humanity was a little more perfect maybe we could have pulled it off

Re:Fusion energy breakthrough by Livermore Lab by gjm11 on Tuesday December 13, 2022 @08:38AM (#33968642)
People think of Fukushima as (1) one of the very worst nuclear incidents there has ever been, and also as (2) something that cost very few lives.

Yes, something like 150k people were evacuated because of worries about radiation. What you don't mention is that the total number of people evacuated was 470k. Most of the people who had to leave their homes had to leave not because of anything nuclear but because the enormous tsunami destroyed their homes.

So the Fukushima story is: massive natural disaster that caused enormous destruction and tens of thousands of deaths; a nuclear power plant was in a badly affected area; the damage was expensive to deal with but the total number of resulting deaths was, er, maybe about 1.

Re:Fusion energy breakthrough by Livermore Lab by htag on Tuesday December 13, 2022 @02:43PM (#33974604)
I think you're missing key elements to the Fukushima story. It wasn't a surprise natural disaster, it was a predictable eventuality.

1. People tried to ring alarm bells about the building codes (and the reactor specifically) not being able to handle earthquakes of a size Fukushima was likely to experience. They were on deaf ears.

2. Japanese government admitted guilt for poor oversight and regulation.

3. Three executives were put on trail for negligence. There were found not guilty, but that's not the same as innocent.

Re:Fusion energy breakthrough by Livermore Lab by gjm11 on Wednesday December 14, 2022 @03:16PM (#33989726)
Oh, for sure, Fukushima's story is not one where everyone did the right thing. It's one where there was negligence and carelessness, as well as a huge (and, yes, in some sense predictable) natural disaster ... and despite all that, the actual reactor-related consequences were not so very bad.

If the question were, say, "how much should we trust the Japanese government?" then Fukushima is not very encouraging. But if it's "how worried should we be about nuclear power?" it seems pretty encouraging to me. Lots of errors and negligence, huge natural disaster, and even so scarcely any lives lost and most of the harm done would have been the same without the nuclear power plant.

Nuclear fission is probably one of the greatest victims of populist democracy. It seems the more modern "socially-democratic" a country was over the last 30-40yrs the more anti-nuclear it became. The raw output of markets or the tough hand of socialist dictatorship was the biggest positive driving force in the early history of fission energy.

But ultimately it's such an expensive and society-tier level of investment that it's at the whims and pressures more than almost any other technology that has benefited society in resent history. So likewise it's also most at risk of the downside of populist politics (short term thinking, highly reactive to noisy local issues, driven by emotional outrage, etc).

I wonder if it's prospects are even worse off now that's to social media.

Oh yes indeed. Nuclear energy is not legal in Italy, so I did some research:

We had nuclear reactors in the 80s, until we held a referendum on nuclear energy, 3 months after Chernobyl. The result: overwhelmingly against, so we dismantled our reactors. Decades later, the Government pushed for a new referendum. When did they choose to do it? 6 months after the Fukushima disaster... you can guess what did the Italian population voted for.

Is this true?

I always considered fission tech to be used for the following reasons, and none of them are economic. The number's I've crunched say fission isn't the economic choice, but that varies depends on how much value is placed on 'base load'.

1. Cold war era vanity tech. Nuclear weapons were used to end World War 2, and now they are just another infrastructure project for us.

2. Code shifted weapons research. Countries blame each other for this all the time in the nuclear non-proliferation era.

3. Strategic choice to avoid traditional energy imports (France, Japan).

Re:Fusion energy breakthrough by Livermore Lab by panick21_ on Tuesday December 13, 2022 @12:20PM (#33972113)
I disagree that its not the economic choice. I think everybody would agree that for 50 years before lets say the year 2000 is was overwhelmingly the only economic choice for green energy (outside to hydro limited by geography).

After 1990 specially 2000 lots of governments around the world started to massively subsidize solar and wind. While often at the same time having policies punishing nuclear in various ways.

The uneconomical solar and wind became economic because of massive government orders and investment. Even the US often simply set targets for solar and wind that utility providers had to reach. Even nuclear nations like France did so.

So why did wind and solar turn economical, massive investment around the world in making it so. Had Germany, France and the rest of the EU simply gone all in on even a Gen3+ reactor design, and had order 200 of them since 1990, it would also be very economical. History of nuclear shows that if you build the same plant in large numbers, they can be built and finished far faster and cheaper.

And that is even before we consider the huge reduction in capital cost if you go from a PWR design to a GenIV design. Just in terms of the scale of the project, there is a huge difference. Sadly by the time that technology was getting ready for serious commercialization, nuclear was basically seen as legacy and almost all government stopped most research and stop investing in it.

Imagine if nuclear in the 80s had the support wind/solar did in the last decade. If every utility in the US simply sad 'you need X% nuclear by Y date'. And in Europe at the same time as France was building its reactors, Germany, Nordics, Switzerland, Austria, Italy, Britain had also built reactors at the same time.

During the Kyoto protocol talks, France already had a mostly green grid because of nuclear. But somehow essentially nobody copied this success story because it simply wasn't politically viable in most places. It took decade plus after Kyoto before wind/solar were commercially viable but really only if you don't consider intermittency a problem and the market doesn't give you a penalty for it (it usually didn't because before wind/solar that just wasn't an issue). Yet despite solar and wind not being economical, massive investment in it happened and eventually it was made economical thanks to economics of scale.

I would claim if all the investment that was made in wind/solar since 1992 had been made in nuclear, we would produce more green energy now and the cost curve would be driven even lower, and baseload power would be solved as intermittency is simply not a thing. We would not need to redesign grids because nuclear plants would map nicely onto the current grid, if you just replace coal with nuclear.

So, its all about economics of scale, that makes it energy production cheap. Putting up huge wind mills is cheap because there are lots of trained people to do it, the factories can produce large volumes. The largest wind mills now are by themselves large then a whole GenIV plant would be. And produce like 95% less energy and not even consistently.

> I always considered fission tech to be used for the following reasons, and none of them are economic.

You missed that it is green and no CO2. That was not a reason anybody cared about before 2000 but since then it was part of the rational in some countries.

I would like to hear why you think fission can't be economic in principle. Maybe you can make the argument that Gen3 reactors can't be economical but based on first principles, fission itself can be economical if you had economics of scale seems a stretch.

Re:Fusion energy breakthrough by Livermore Lab by winReInstall on Tuesday December 13, 2022 @03:36AM (#33966203)
I think fissions failure is a inability to plan for complete failure scenarios, were society folds in on itself, suppliers are no longer available or power plants are actually fought over. So the inability is not to get the tech going, but to plan for how it can it be usefull in a unravelling world.

Already economic downturns corelate with fission problems, as plants are not properly maintained. We have one blowing up every thirty years atm. Our reach exceeds our grasp, and there is no shame in admitting to that.

Are you referring to the need for electricity now at the Ukraine plants? Newer technologies such as NuScale require no external electricity for their cooling. The reaction only occurs if there is water and when all the water evaporates then the reaction stops.

> Already economic downturns corelate with fission problems, as plants are not properly maintained. We have one blowing up every thirty years atm. Our reach exceeds our grasp, and there is no shame in admitting to that.

Gas turbines in aviation also blew up way more often in the past than they do now. Who says the blowing up of plants is a constant? There have been many improvements in safety. Also, apart from the Three Mile Island accident, there haven't been major nuclear problems in the US in the last 50 or so years. Furthermore, the thing that lead to the Chernobyl disaster is not possible, by law, in modern reactors. Furthermore, newer reactors require an extra casing of concrete which would also have contained the Chernobyl disaster. You can even fly an airplane in those newer housing buildings and nothing would happen (with the building at least).

Re:Fusion energy breakthrough by Livermore Lab by winReInstall on Tuesday December 13, 2022 @09:00AM (#33968908)
There has been a major back-logging in nuclear equipments investments, so big in fact, that some countries who should by right be netto exporters of energy (france) became importers. Its a valid technology in a theoretical world, that does all the upkeep measures, does actual credible threat analysis.

I have yet to see such a world.

Re:Fusion energy breakthrough by Livermore Lab by panick21_ on Tuesday December 13, 2022 @12:23PM (#33972165)
Its simply about economics of scale.

If you built nuclear at scale, then these problems solve themselves. Just as France solved them in 15 years in the 70/80s.

Just as these problems were solved for solar/wind by economics of scale.

Solar/wind was not economical, it was basically forced into being economical by creating economics of scale.

Re:Fusion energy breakthrough by Livermore Lab by panick21_ on Tuesday December 13, 2022 @02:14PM (#33974197)
In 2014 the government they elected basically went all in switching to renewables and they actually stopped or delayed a lot of stuff.

That said, well, they stopped building new reactors, most of their reactors were built in 15 years in the 70/80s. Since then they have not done as much as they should have and all those reactors are starting to need more maintenance now.

Because they have not built much new things, they don't have as many people with knowledge as they used to.

But they are managing most of these issues pretty well overall.

I would say France did pretty well having 40 years of green energy.

Yep, and fusion reactors will probably be even more expensive (especially the first ones). Looking at the current prices of renewables, I don't see a market for fusion reactors at all to be honest.

After all we already have a giant fusion reactor just 12 light-minutes away from us! We just have to harvest that energy. The direction were already going (mostly market-driven nowadays actually!) is generation from renewable sources, flexible grids and storage systems to balance everything out.

Re:Fusion energy breakthrough by Livermore Lab by sushisource on Monday December 12, 2022 @07:31PM (#33962765)
This minimizes the main problem with really going full renewables, storage. Fusion is 24/7 output at the same level. Solar and wind are not, which means batteries, and all the problems associated with that.

Fusion could obviate the need for grid-wide storage systems which would be a huge advantage.

Re:Fusion energy breakthrough by Livermore Lab by preisschild on Tuesday December 13, 2022 @03:57AM (#33966327)
Unfortunately 100% renewable advocates just throw LCOE numbers around even though LCOE doesn't account for storage at all.

Levelized Full System Costs of Electricity (LFSCOE) does include storage and suddenly nuclear fission gets a lot more competitive:

Economic challenges of quickly building grid-scale battery storage , battery production for the entire globe, NIMBY's etc.

Well overwhelming bulk is a high bar and storage is geography dependent. Germany f.e. can't build as much pumped storage as Australia and Australia built a large amount of battery storage vs PSH.

Lithium-ion batteries burn. But the topic was "modern batteries", which at the instant moment means LiFeP batteries, not "previous-generation batteries".

Lithium is anyway not favored for use in utility-scale storage, where its light weight offers no compelling value. Up-and-coming chemistries include iron-air (no explosions), calcium-antimony (no explosions), and bromine-zinc (no explosions). Hundreds of other chemistries are available.

Re:Fusion energy breakthrough by Livermore Lab by Schroedingersat on Monday December 12, 2022 @11:15PM (#33964760)
Making the box of salty radiation medicine an order of magnitude cheaper and shoving a bit of hydrogen in a salt cavern solves the storage problem (which is already far smaller than you're pretending) entirely.

Fissions reactors that don't have incredibly strict and expensive regulation are already pretty unreliable, and they're operating within the bounds of known materials rather than an order of magnitude outside of them.

Even the mythical 100% uptime nuclear reactor still needs just as much storage for abritrage because it is so much more expensive.

Re:Fusion energy breakthrough by Livermore Lab by crote on Monday December 12, 2022 @07:21PM (#33962645)
Safety standards were set higher and higher because accidents kept happening, resulting in some well-known extremely large scale disasters and numerous minor ones. As with every industry, the rules were written with blood.

When you are building a power plant which has the capability of making a significant portion of your country permanently incompatible with human life, you generally want to be really sure you aren't going to have an oopsie.

Re:Fusion energy breakthrough by Livermore Lab by epivosism on Monday December 12, 2022 @08:25PM (#33963339)
I accept this as one point; I do question whether the opposite side of the benefit calculation was made - i.e. did we have a public debate where we correctly looked at the tradeoffs of increased fossil fuel carbon pollution, economic impacts from lack of energy and failures to advance, balanced out with honest cost estimates of disaster profiles? It doesn't seem like it. It seems the debates were fairly one-sided; this leads me to believe a better outcome would be weighted more towards pro-nuclear.

I think Chernobyl was the only really big nuclear plant disaster right? And even then, what we've really learned in the long term is that human habitation is more dangerous to wildlife than nuclear radiation (the area around the plant is now a thriving wildlife preserve).

There was simply a false assumption about how dangerous radiation was. Some of this still persists to this day.

A nuclear reactor that had the same radiation as a coal plant would not be legal? How does this make any sense at all?

The Safety standards were actually put at to high a level to early, specially given how instantly save nuclear was.

Consider this, how safe were coal plants? Would nuclear instead of coal have saved 100000s of lives since then? Yes of course nuclear would have, even if you had an accident once in a while.

The problem is that there was 0 tolerance for nuclear accident, because of populist nonsense, but if coal plant and supply chain killed 5 people here 10 people and 1000s of people get sick, nobody cares.

So the reality is, that nuclear went uneconomical because nuclear and existing power production (mostly coal, later gas) were no treated the same in terms of their safety requirements.

> When you are building a power plant which has the capability of making a significant portion of your country permanently incompatible with human life

That's not actually what happens. 3 Mile Island or Fukushima didn't even remotely come close to what you describe. And even for Chernobyl this is questionable statement. And Chernobyl was a type of reactor not built in the West, so in the West something that bad simply can't happen with PWRs.

Re:Fusion energy breakthrough by Livermore Lab by joak on Monday December 12, 2022 @09:23PM (#33963871)
The learning cycle is too long. It takes ~10 years to build a reactor, so if you spot a way to improve on costs or safety it will take another 10 years for the innovation to see the light.

At the contrary in renewables the learning cycle is in months so costs fall exponentially.

That's the real reason of high costs in fission, not red tape or public sentiment.
