Who pays decide (Germany is the first financial contributor), that's business as usual.

> Whereas the CO2 is in the air

In the UE the question is how much renewables and how much nuclear will be built, and their (dubious) compatibility. Very few want to see more fossil fuel.

The "nuclear waste is a solved challenge" is funny, as experts explicitly state that there is no safe solution (due to risks induced by seismotectonics, intrusions, casks imperfections...).

It's the "Asse II mine" joke all over again: "there will be no problem" followed by "Ouch! Err...". https://en.wikipedia.org/wiki/Asse_II_mine#History

What is their definition of safe?

> It's the "Asse II mine" joke all over again

It would be good to see the cost/benefit analysis of the proposal to remove everything from the mine

https://www.nwtrb.gov/docs/default-source/meetings/2018/marc... page 17 has backfilling as the preferred option in 4 out of the 5 assessment categories.

> definition of safe?

Some claim that nuclear waste repositories are perfect (0 risk), and experts disagree.

> backfilling

Yay, such a superb gift to our children, their children, their children...!

The underlying point is about how much renewables and how much nuclear may we build in order to tackle current challenges (climate, pollution...), one of the criteria is waste and renewables win hands down.

> Some claim that nuclear waste repositories are perfect (0 risk), and experts disagree.

Disagreement is natural in science as well as engineering. And absolutes are not. Framing nuclear waste disposal, or in fact any enterprise, in terms of finding total agreement on total safety is not useful.

> one of the criteria is waste and renewables win hands down

In what terms are we to assess the waste? By volume, likely number of people killed over the lifetime of the waste, maximum number killed? Do we count the waste from manufacturing as well?

> Disagreement

Indeed, my point was about a form of propaganda quite common in France, which states that long-term waste repositories (now work-in-progress) will be perfectly safe. They won't.

> assess the waste?

Most of renewables' waste is recyclable, and more and more is recycled, even wind turbine blades.

> likely number of people killed over the lifetime of the waste

The more types of waste and the longer the lifetime (nuclear...), the more difficult it is.

> count the waste from manufacturing

As far as I understand yes, an adequate life-cycle assessment ( https://en.wikipedia.org/wiki/Life-cycle_assessment ) has to do so, however this is a good point: it may somewhat be neglected.

The experts literally said that digging up Asse II was useless and it was safe to leave the waste down there

https://www.ssk.de/SharedDocs/Beratungsergebnisse/DE/2016/20...

It was a political decision by the greens to waste money.

There are dissenting opinions: https://en.wikipedia.org/wiki/Asse_II_mine#Current_progress

In not-so-ancient times "experts" were also OK with ocean disposal. https://en.wikipedia.org/wiki/Ocean_disposal_of_radioactive_...

AFAIK few experts now judge adequate to use such mines, and many nations build dedicated repositories.

> There are dissenting opinions

Flat earthers exist too.

> In not-so-ancient times "experts" were also OK with ocean disposal.

The link you gave did not list the effects of ocean disposal; elevated and measurable are not the same as significant or harmful unless you are a firm believer in LNT, although at the bottom of the ocean the background radiation dose from cosmic rays will be less.

> File earthers

Whatever they believe or not isn't impeding others' lifes.

> ocean disposal

AFAIK no expert now states that ocean disposal is OK, this is a settled matter since at least 1972 ( https://en.wikipedia.org/wiki/London_Convention_on_the_Preve... ), therefore a bunch of assessments of the current situation for stuff dangerous for at least hundred years doesn't seem pertinent to me.

> Whatever they believe or not isn't impeding others' lifes.

The principle is that we don't seek unanimity before proceeding with something.

> this is a settled matter since at least 1972

Disposal of small amounts of radioactive material at sea and into the air happens (e.g. reprocessing plant water releases, power station tritiated water releases).

An international convention does not settle the science behind ocean disposal. The lack of supporters perhaps reflects the difficulty in carrying out such research, and the problems of trying to change international agreements.

> we don't seek unanimity before proceeding with something.

> this is a settled matter since at least 1972

This is an opinion. My (dissenting) one is that the more someone is or could be impacted, the more we have to take his/her opinion into account.

> Disposal of small amounts of radioactive material at sea and into the air happens

It doesn't imply that it is an adequate way to dispose of it.

> An international convention does not settle the science behind ocean disposal

"The main objective of the London Convention is to prevent indiscriminate disposal at sea of wastes that could be liable for creating hazards to human health; harming living resources and marine life; damaging amenities; or interfering with other legitimate uses of the sea." ( https://en.wikipedia.org/wiki/London_Convention_on_the_Preve... )

> The lack of supporters perhaps reflects the difficulty in carrying out such research, and the problems of trying to change international agreements.

Nuclear-waste long-term repositories projects are very expensive and difficult (to the point of many attempts failing flat) everywhere, therefore attempting to convince that ocean-dumping is OK would be useful.
