Lumping together fission (the kind we use today to produce energy) and fusion (a kind we have never made a power plant of but have high hopes in the future) is questionable.

You source says in 2022, fission + fusion totaled 4.94 billion in R&D funding. This source says that in 2022, increases in fusion investment raised of more than 2.8 billions. I am willing to bet that the huge majority of these 4.9B of R&D investments are in fusion.

You could say the same about renewables. Solar and wind are very different technologies. At the same time there are a lot of renewables, which have failed so far. I am thinking wave power, concentrated solar, geothermal and I am propably missing a lot of others. We did spend a lot of money at those as well.

Point is we have spend more money on fission R&D then we spend on either solar or wind. If anything we spend too much on it and should have spend more on solar and wind in the 90s.

Solar and wind are working power sources right now, like are several fission technologies. Nuclear fusion has never generated net power anywhere and has never gone out of the lab.

No one who promote nuclear energy right now is promoting nuclear fusion, it is a non-existent tech as of now.

Point is we have spend more money on fission R&D then we spend on either solar or wind.

[citation needed] The article was not showing that at all.

Here you go. It is fission alone in two year pairs and it still gets more funding then wind, solar, hydro and oceanic power combined.:

Quite frankly, I am interested in the actual answer. My gut feeling is that renewables received more R&D than nuclear fission but I would be happy to correct my misconception there. But the IEA numbers are really small. 1.3 billions for 2 years of nuclear R&D? France's CEA, that oversees nuclear R&D (among other things, but mainly) has a 5 billions yearly budget.

R&D of the 21 top leading solar firms has exceeded the billion since 2017: https://www.actu-solaire.fr/a-10681-les-depenses-de-r-d-dans-le-photovoltaique-depuis-cinq-ans.html

The IEA numbers seem biased in that they just include a fistful of countries. They do not include China (that does a ton of solar R&D) and include France (one of the last to do nuclear research).

CEA also hosts ITER and France pays 40% of the costs for that. It might go throu CEA. I honestly do not know.
