Fun fact most people don't realise, that there is no safe radiation dose limit, no one knows what it is, and all the numbers are basically pulled out straight form a hat. Also, there are places on earth where background radiation is greater than in Thernobyl, and yet those zones are not quarantined.
Besides all the waste discussion seems to be centred around weapon grade or some prehistoric reactor designs. Modern ractors produces fraction of a waste, and almost all of it can be reprocessed.
Yes, I mentioned water being runner up with nuclear. However, how about the countries with no access to see? There ale few places on earth where, if solar power plan has been installed there, it could supply energy to ENTIRE world. The problem of energy transportation and storage makes those site as unsuitable for such investment. This is exactly problem with Tidal. It can be an alternative source, never strategic one.
