Firstly, the containers are known to develop leaks over decades. Secondly, there are accidents on site every year, causing tritium leaks if not also uranium. There is also a baseline level of tritium leakage that's considered normal, but it isn't actually normal for the fishes in the river.
> I prefer to assume we're comparing competent operators
Please see the list of leakage incidents at each nuclear power plant. There is one almost every year at almost every site. The local environment pays the price for it. If they were competent, these events wouldn't happen.
None of this is an issue with solar, for example. The radius of the possible damage is minuscule.
