In comparison, coal and oil produce air pollution that you cannot sequester, that you have to release in the air for people to breather. Oil further produces liquid waste that is very difficult to sequester and regularly destroys the environment, and poisons drinking water. Coal further produces massive amounts of coal ash, that is incredibly dangerous and hard to store and regularly gets released into the air or the drinking water when hit by extreme whether.
Nuclear produces waste that must be continuously cooled at great cost so that it does not set itself on fire and release massive amounts of radioactive gasses. Even then, the complex cooling systems regularly fail, and do occasionally release massive amounts of radioactive gasses.
All of the above not only produce much more waste but their waste is far more dangerous and damaging.
Seems like you are talking about high-level waste (HLW) which is just 0.2% [1] of all radioactive waste by volume.
The cooling you are referring to is a passive cooling pond [2], there's no active cooling. There are no radioactive gases escaping from the spent fuel - not small or massive amounts. Spent nuclear fuel is a solid. Liquid waste is from weapons programs, not power generation.

Is radioactive fuel wildly more difficult and dangerous to manage than a few thousand inert turbine blades? Absolutely.

In this case, it seems more like a logistics problem than an environmental one since the blades are made from inert materials and therefore good candidates for landfill. I'm assuming the cost does not justify crushing it for other uses but it could be done at some point if needed.
Also, you're literally commenting on an article about it in a major media outlet, so I'm a bit dubious about this "no-one wants to talk about it" thing.
I think it's fine not to talk about it because people will easily get stupid ideas like renewables being just as bad for the environment.
Cost, land / real estate, storage, and transport are some real problems.
How does it compare to traditional energy sources in terms of volume and toxicity?
Non-green energy releases more than 2 million tons/second of CO2 alone every day.
There probably haven' been 2 million tons of turbine blades produced in history.
