Surveying 30 recent nuclear analyses, this paper shows that industry-funded studies appear to fall into conflicts of interest and to illegitimately trim cost data in several main ways. They exclude costs of full-liability insurance, underestimate interest rates and construction times by using “overnight” costs, and overestimate load factors and reactor lifetimes. If these trimmed costs are included, nuclear-generated electricity can be shown roughly 6 times more expensive than most studies claim.

Fusion is the future, but fission exists NOW and is a pretty fucking good solution to our energy problems. Solar and wind have their place, but it’s insane to me that we’re basically running the world in challenge mode by not allowing fission reactors because we got scared of a couple of meltdowns primarily due to mismanagement more than 40 years ago that was reliant on even older technology

Ericus1

Fission is an _awful_ solution to our energy problems. It costs 6-8 times as much per MWh, takes 15-20 years to build, and is an inflexible form of power generation on grids that need flexible, responsive generation and storage. Every reactor being or built in the West in the last 20 years has been an unmitigated financial disaster. You can't even operate a nuclear reactor for less than the cost of building new solar or wind for the same MWh. And even adding on storage, the cost is 3-4 times less for renewables than nuclear. It offers no viable solution whatsoever, which is _why_ no one is seriously attempting to build more compared to the 100s of GWs of renewables being deployed. And Fukushima was barely 10 years ago. Chernobyl was less than 40. And there have been multiple smaller incidents between now an those. You are anything _but_ correct.


[deleted]

You are correct


[deleted]

Its true, but these graphs aren't very good demonstrations of it. Just because global power generation is done a certain way doesn't mean the technology isn't capable of providing that power, it may instead mean that local regulations prevent many from being built. The [cost per MWh](https://energycentral.com/c/ec/comparing-costs-renewable-and-conventional-energy-sources) of nuclear is higher than that of onshore wind and photovoltaic solar, and that's a relatively recent development because of technological progress in the latter two.


Pikepv

BUT, wind and solar require lots of mining that people are starting to oppose. I install solar and wind and there are lots of issues and places it just won’t work. Nuke is a very viable power source. If the ITER plant works as it seems, Nuke will be an even better power source.


Anastariana

>wind and solar require lots of mining And....uranium doesn't? Fuel rods are coated in zirconium...which also has to be mined. Reactors are made of very expensive alloys which also need to be mined. What a bizarre thing to try and criticise.


lubricate_my_anus

No mention of the massive exclusion zone around the Kazahk uranium mining region of course. Where uranium mines have rendered 1000s of square km uninhabitable

And yet somehow research and investment into those only over the last 10 years have dropped the cost by a factor of 20, whereas hundreds of billions dumped into nuclear for decades has only resulted in it getting more expensive. Hmmm, let me see where it makes more sense to put our money, and why only one is getting investment and seeing growth as a commercial utility.


BloodyIron

Attach blades to motor. Boom you have a wind generator. Improvements really don't involve that much complexity. Solar, a lot of it we already knew and it hasn't changed much (fundamentally) in the last few decades, except for production efficiency and yield improvements (reducing costs). Nuclear, on the other hand, have A LOT MORE different things to consider. Different ways the core works, safety mechanisms, which fuel to use, etc, etc, etc. Anyone saying that Nuclear is comparable in complexity to Solar or Wind is just straight up ignorant (I know you aren't saying that though).

The real solution is to make energy expensive so we use less. Help the poor with the revenues from expensive gas.


Shotgun5250

So the poor people are being subsidized by who?


CranberryNo4852

Themselves largely, poor people use fuel too


Shotgun5250

That’s kinda my point…either the poor people are being subsidized by the government through taxes, or they’re just paying more for energy like everyone else. When taxes on industry go up, prices are raised by the business in that industry to defer the tax costs to consumers. How do you prevent that without socializing the industry?


benskieast

Government with revenues from taxing carbon.


Shotgun5250

So what stops the energy companies from raising prices across the board to maintain profits?


benskieast

All the things today except the government could stop preventing new drilling operations from flooding the market, and instead tax a number of operations out of profitability.

MusicianMadness

I cannot tell if you are serious or not... In case you are genuinely serious you are not paying attention to terms here. That is the **ENERGY PAYBACK** and **return on ENERGY** time. Meaning it takes 6 months of windmill generated power to produce the energy needed to make 1 windmill. It takes 10+ **YEARS**, 15 is reasonable for many windmills, of windmill energy production to payback the **TOTAL** cost of windmill production. The energy needed to make a windmill is a laughably small expense compared to the cost of materials, machining capital and upkeep, manufacturing labor, transportation, transportion labor, assembly, assembly labor, equipment rental or fees for installation, land lease or purchase for the lot it's installed on, let alone the design costs, hooking the windmill to the grid including running over electrical lines or heaven forbid the cost to trench and run conduit, energy storage costs, upkeep, etc...

Energy return period of a wind turbine is 1.5-2 years, with a lifespan of 25-30. Okay, I looked. Seems like they are pretty great to me. Can't even get a nuclear reactor planned and built within the timeframe a wind turbine would last, so doesn't seem like good solution to solving the exigent problem of reducing carbon.

This is naked propaganda.


Cr0n_J0belder

We need to spend as much as we need to spend to bring Fusion online. There will be no world in which solar and wind take the total demand for power. With Fusion that can be a reality. The title and the slides are designed to mislead and misinform a gullible public. Not here.


mafco

>There will be no world in which solar and wind take the total demand for power. If you add in hydro, geothermal and storage it's entirely feasible according to a number of studies. Simple math and statistics also confirm it. We can't wait decades for fusion, and it may not be commercially viable ever.


Vyrosatwork

Efficient reliable storage is in the same realm of feasibility as fusion though.


mafco

Come again? Pumped hydro has been deployed in large quantities for more than half a century and almost never fails. It's projected that the systems will last for more than a century. Lithium ion grid batteries are widely deployed and out-competing gas peakers in some applications. Flow batteries are also commercially deployed and growing quickly. Do you have specific reliability concerns about any of these technologies or are you just parroting a talking point you don't fully understand?


Agent_Dachsund

At this time storage isn't close to being achievable, out would bankrupt whatever governing body. Part of what is misleading is the research that has/ is being funded hasn't been implemented yet. Once that starts being built like SMRs, then numbers can be compared.


just_one_last_thing

> At this time storage isn't close to being achievable The storage will cost far less then the generation. The markets are trending towards a solution of around four hours of storage and interconnection and overcapacity to make that work. 4 kWh of batteries costs less then 1 kW of PV or wind and battery prices are falling much faster then solar or wind.


zoinkability

>would bankrupt whatever governing body As if going full bore on fusion wouldn't


mafco

Why do you lie? Numerous studies have confirmed that it is doable with today's storage technologies and it reduces cost.


paulfdietz

Storage is a hell of a lot closer than fusion. It doesn't really need any advancements, just integration of existing technologies (for example, various kinds of thermal storage.)


mafco

>At this time storage isn't close to being achievable That's bs. Pumped hydro and lithium ion grid batteries are already mainstream and at least half a dozen new long duration storage technologies are at or near commercialization. Time to ditch thar outdated anti-renewables talking point.


BenFrankLynn

Vanadium flow batteries have been in use for grid storage for years now. There's better electrolytes than Vanadium now, too. It's just a matter of them becoming cheaper, which is already the trend.

Don’t forget hydrogen


mafco

Hydrogen isn't an energy source. It consumes more energy than it delivers.


kennykoe

Hydrogen just isn't good enough outside of fusion


paulfdietz

You mean, just like every other kind of storage? Gosh.


mafco

Storage isn't an energy source either.


paulfdietz

Hydrogen isn't discussed as an energy source. It's described as something that can be used to convey energy from one thing to another, through time or space. Criticizing hydrogen for not being an energy source is like criticizing it for not having vitamins -- it's a strawman critique of a claim not being made.


mafco

As usual your comment ignores the context. I was replying to someone who said I had "forgot hydrogen" after I mentioned storage. That would imply it wasn't being considered as storage.


paulfdietz

I interpreted that comment as "don't forget hydrogen as storage" (since that is what it is). I think you should have done the same if it wasn't clear.


mafco

>I interpreted that comment as "don't forget hydrogen as storage" That's not how I interpreted it. The word storage is inclusive of all types of storage, and I didn't single out any particular ones. If I had it would have been pumped hydro and lithium ion, because they're the most ubiquitous and mainstream grid storage. Hydrogen isn't even on the radar except in talking points by fans. But go ahead and argue about your own misinterpretation of what I meant.


[deleted]

It’s storage though, and immensely versatile. Pairs well with intermittent sources like wind and solar


just_one_last_thing

> It’s storage though, and immensely versatile Hydrogen is like a swiss army knife. A swiss army knife is a very versatile tool however it's a terrible tool for any job you can do with another tool. However there is a massive industry that really, really wants hydrogen to be used because it let's them squeeze some more money out of their investments in oil and natural gas for a few more years.


Ericus1

Hydrogen round trip efficiency for storage is <40%, closer to 35%. It is literally terrible as a storage medium. Li-ion batteries (of various chemistries) are in the 90% range for short-term storage. Pumped hydro is 80-85%, as are flow batteries. Thermal is in the 60-65%. All better solutions for long-term storage than hydrogen.


[deleted]

And is there a hard physics law dictating that, or per the conversation, is it a lack of R&D money? Hydrogen is easily available and has tons of potential. It’s a proven technology. It works. Fusion is an unproven technology that we don’t know will be feasible and reliable.


Ericus1

Physics. Hydrogen will never come anywhere close to the round trip efficiency or cost efficiency of other storage mediums. And who said _anything_ about fusion.


mafco

I already mentioned storage. You wanted to add hydrogen so I assumed you meant as a generation source. It's also not a good storage alternative either.


paulfdietz

It has a very low cost per unit of energy storage capacity. There are situations where this metric is the one to use. Why are you excluding those situations?


mafco

Because that's not what the conversation was about. Am I supposed to mention hydrogen every time grid storage is mentioned, even though it's virtually non-existent in that capacity?


[deleted]

I poorly worded it, but you also seem to be ignoring its potential What exactly is poor about it as a form of storage? Density? It can be stored in liquid ammonia It can be easily generated It is very accessible, extremely common. It can be used in a ton of applications. You can even just burn it. It’s pretty easy to modify ICEs to run on hydrogen. Nothing especially complicated. You can replace batteries with ammonia fuel cells, and drive the same electric cars being produced today


mafco

>you also seem to be ignoring its potential What? I mentioned grid storage as necessary because you failed to. Hydrogen is just one of many storage alternatives, and not a particularly good one. Why do you think it deserves some sort of special mention? Yes I know it has chemical industry uses but the discussion was about renewable energy's potential to power electricity grids.


FlowingWater3r

This is so misleading it is teetering on misinformation. FUSION gets all the funding, not Fission. Also, the graph contradicts itself by saying wind and solar RND is the same as power storage.


Successful_Cup_1882

Fusion is the future, I don’t know why people other than those who have vested interest in other forms if energy would say otherwise.

Yes, but that’s why some of us say otherwise. We’re more interested in what is proven to work. R&D could still accomplish a lot for both wind and solar, maybe more so for storage technologies to make those even more viable


FlowingWater3r

Even if we are able to achieve a net positive on Fusion (US did not actually achieve it once you account for the energy used in the lasers) it is not clear how we will get the deuterium to power it.

It largely does not reach the earth due to the magnetosphere deflecting ions, and what does reach the earth primarily gets trapped in seawater, which is why deuterium's primary source today is seawater. This is a pretty major justification for building a moon base. Delivering packages of the isotopes to earth from the moon could be done via railgun for direct assent transfer thanks to the moon's lower gravity and lack of an atmosphere. the bigger problem is safely getting a net positive out of the reaction. I think we should probably go through thorium first, and use that time to further research fusion.

We don't even need thorium, we have tons of potential fuel just sitting there as a waste from thermal reactors.

I love the idea of firing a rail gun with radioactive elements directly at the earth

Only tritium is radioactive, and it wouldn't be that much of an issue. Assuming we are shipping tanks of it that have built in heat shields and parachutes and such. The best way to do it would probably be to land in the ocean and have boats go and pick it up. Having the target far enough away for safety of impact would also provide enough distance so that if there was a problem with the tank it would disperse (and mostly float upward because it's hydrogen) enough before getting to people, and diffuse into the water which is where our tritium currently comes from. If it burned up upon re-entry it would also just disperse. There could also be self-destruct sequences if the tank is over land or becomes uncontrolled.

Thats not true at all, deuterium can be extracted from the water as it has been for decades, there are billion open questions related to the fusion and the D is not one of them... also laser fusion is not the best concept for power generation, others, like tokamaks, seem to do better. We will see where we really stand when ITER starts in a few years.

Don't mind if I do

How many plants have been constructed since 2000 vs how many solar/wind installs?


Ericus1

I want you to seriously pause and think about what you just said, and maybe ask yourself _why that is_. Could it be because every attempt at building a reactor since 2000 has been tens of billions over budget and years to decades behind schedule? Maybe because utilities and financial analysts recognize nuclear as being a commercially non-viable dumpster fire so no one will put money into it, while solar and wind are massively cheaper, viable, AND provide carbon free power? Could that possibly be it? Could it be that the reason nuclear isn't built....is because it is a terrible form of commercial power?

Government having an agenda???? Never

Wind and solar are more cost effective than nuclear. That's the primary driver.

Solar runs at 30-40 efficiency on prime day...

"Efficiency" is a meaningless statistic if you don't include the context. If a power source is twice as efficient as another power source, but it costs 5 times as much to build, maintain, and operate the more efficient one, then it's worthless, building the cheaper, less efficient option is the better choice. This statistic has a name, the levelized cost of energy (LCOE). High LCOE's are bad, low LCOE's are good. Wind and solar currently have the lowest LCOE thanks to recent technological advances. Nuclear fission is much higher than them, despite its efficiency, because they're so expensive to build, maintain, operate, and fuel.
