I guess since we know about the problem and someone wrote an article saying we should fix it, it's taken care of?

That doesn't change that you've made a total apples to oranges comparison by using the environmental cost of nuclear fuel to the cost of having a solar panel.

Both produce a finite amount of MWh for their lifetime. Both require mining. How much mining and human rights violations exist per unit of energy produced is the metric you're looking for.

That's complicated though. Easier to pretend like it's zero for one and non-zero for the other.
