Not sure why I even bothered digging into it, but for example one later point is also misleading: "uranium resources will be depleted by the end of this century".
I think I found the source (not that they link it, that would be too easy, but by ducking around for this number):
> the total identified amount of conventional uranium stock, which can be mined for less than USD 130 per kg, [was found] to be about 4.7 million tonnes. Based on the 2004 nuclear electricity generation rate of demand the amount is sufficient for 85 years, the study states. Fast reactor technology would lengthen this period to over 2500 years.
> However, world uranium resources in total are considered to be much higher. Based on geological evidence and knowledge of uranium in phosphates the study considers more than 35 million tonnes is available for exploitation.

I'm not sure how the "city of vienna" can read this and summarize it down to say that we'll plainly run out of uranium by 2100. That's just not what the source says. Maybe that's what makes this "reference" "handy" for people with a certain preexisting opinion?
The same bullet point continues with some other interesting claims, let alone the rest of the page, but let me quickly close that tab before I feel inclined to go down more of these rabbit holes...
