The comparison of a happening with basically no longterm consequences to future generations like MH17 to nuclear fallout / necessary waste treatment is quite lame imho. Nuclear energy without subsidies is not sustainable at all. Just do the math if you need decades to dismantle and decontaminate an old nuclear power plant alone.

> Nuclear energy without subsidies is not sustainable at all And yet we seem to be doing just that here in Finland. The for profit companies operating and building the plants have been trying to get permits to build more (and very likely are going to get another one soon). Even with the "failure" of Olkiluoto 3 they seem to find a way to do it in a profitable enough way that they (2 companies TVO and Fennovoima) want…

Where is the money coming from for the mentioned reactor? According to the wikipedia page a lot of French money is involved of a company connected to the French state.. edit: A breeder would for sure be a good way to reduce waste as you said..

Ok, bad wording. How about: It emerges from conventional fixed supply. In any case it's no law of nature. So not a concept that is necessarily relevant in the furure.

Base load results from demand, not from supply. You positively, absolutely must provide a certain amount of power at all times. > In any case it's no law of nature. Yes it is. It's a law of human nature :-)

The relationship of supply and demand in the grid is an equation, if they don't match you get blackouts or other funky things. When you have dynamic pricing, variable supply works out, as nobody is obligated to produce any fixed amount of power.

Yeah,base load still exists as in the dictionary definition (floor of aggregate power supply and demand), but it ceases to be a fixed level that is a hard production quota.

Ridiculous Arm-chair Concept: - What if we make a 1 meter wall thick lead / steel container and seal the waste in and leave it? Surely nothing can break it, not even an earthquake. Just make a giant tennis court sized containers and dump stuff in there. We know how to build bridges, surely we can build large containers. Just want to learn, I am sure this is proposed and would love to know why its a stupid idea.

This is basically what we already do, and it works fine. But opponents will still pester you about where to put the sealed boxes :P

Put it under your home.

There's a lot of straw men being fought in the comments again. The main issue with nuclear power in Europe has always been the storage of nuclear waste, for which many countries still don't have a long-term solution. Proponents of nuclear power like to pretend the opposition exists merely on the basis of "but what if it goes boom!", so they don't need to face the reality that countries like Germany are sitting on a l…

> The main issue with nuclear power in Europe has always been the storage of nuclear waste, for which many countries still don't have a long-term solution. Nuclear waste isn't a problem. It's actually the best type of waste that exists. It's extremely dense, is solid and any leakage can easily detected. And the best part of it, 95% of it can be recycled: > https://www.energy.gov/ne/articles/5-fast-facts-about-spent-.…

Saying Nuclear waste is not a problem is like saying taking a shit in your neighbors yard is not a problem. Shit can be packed into plastic bags, composted, and eventually stops smelling.

Some of us believe that if we can't generate power without creating waste for future generations, we should go without the power.

Seriously, we don't need it.

The error bars make that graph unusable for this purpose.

That’s exactly the point I was trying to make - it isn’t clear that nuclear power has less C02 emissions than wind turbines. It’s also something that needs a very long view to calculate - nuclear waste needs storing and protecting and wind turbines aren’t being decommissioned all that much.

Base load is just a made up convention though closely related to traditional fixed rate prices, and may become increasingly fictional in the future as demand adapts to more variable supply and dynamic pricing.

> demand adapts to more variable supply and dynamic pricing You want demand to adapt? I'm supposed to turn the lights out when the wind's not blowing, or what? Demand shouldn't adapt, supply should adapt. Connect more and bigger power grids, add energy storage to the grid in large enough quantities. Your "solution" is like telling people to give up cars. They won't.

Yes, you get the gist of my position (for cars too).

This is the real issue. It's 3x as expensive as other renewables. Every dollar of subsidy producing 1 MWh of nuclear could provide 3 MWh of solar or wind. Added to which, being a baseload power source is not nearly as useful as being dispatchable (like hydro and natural gas are), and it's insanely capital intensive (which leads to cost overruns - see hinkley point c, corruption & fat profit margins). It's got real lo…

I see you still haven't learned what dispatchable means.

Do you disagree with Wikipedia's definition?

"Dispatchable plants have varying startup times. The fastest plants to dispatch are hydroelectric power plants and natural gas power plants. For example, the 1,728 MW Dinorwig pumped storage power plant can reach full output in 16 seconds.[4] Although theoretically dispatchable, coal and nuclear thermal plants are designed to run as base load power plants and may take hours or sometimes days to cycle off and then back on again."

I just don't really see how this is true. Isn't the basic idea to just dig a really deep hole somewhere geologically stable and dump it in? My impression isn't that the problem isn't solvable, but simply that no one has actually made the appropriate investment yet. That sounds like the same catch-22 as the rest of this. We've thrown up our hands and gone "Not worth it" and then our lack of investment in proper storag…

> geologically stable Isn't really a think when we thing about the time scale of nuclear wast... Additionally Politicians mess in seriously bad ways with anything related to nuclear. Like pushing for nuclear power but if it's found that the objective best place to store the wast underground is around where they live they will try all kind of things to exclude the best suited place from the list of potential candidate…

> Isn't really a think when we thing about the time scale of nuclear waste...

it is.

drill a few miles down into the miles-thick crystalline salt in the permian basin. it will not go anywhere for millions of years.

https://www.lazard.com/perspective/levelized-cost-of-energy-... Wind $26-$54 Nuclear $129-$198

Wind power is cheap when it's windy. When it's still the cost is $+inf. The grid still needs to maintain it's AC frequency.

Wind power producers should be required to buy some kind of base load generation credits.
