The risks _are_ managed. Pretty much every reactor in existence has a negative void coefficient (the more the reactor heats up, the more it is moderated, lowering total energy production, hence lowering heat, etc.) Pretty much every reactor in existence is in failsafe: if power or control is lost, rods close, reaction stops. Pretty much every reactor in existence is not powered by its own output: if your reactor starts going wild for any reason, it won't be able to keep itself powered up. You shut off the small generator outside (and by outside, I mean it is physically _outside_ the reactor building), and it stops. Pretty much every reactor in existence has walls solid enough to block a plane crashing into it. Hell, Zaporizhzhya has been shelled repeatedly and is doing... fine. (As in, the reactor, not necessarily the people).

So, no, nuclear energy is about the safest means of producing energy we have today. Offsetting environmental damage to third world countries to mine your rare earth minerals for solar does not get to make you feel better about it. Nuclear installations are not handled like a shitty startup that goes "wE'Re AgIlE wE'lL dEaL WiTh iT iN tImE". The IAEA is absurdly stringent on their requirements. The ASN in France puts such harsh conditions and requires every crucial safety equipment to be not just doubled, but tripled. There is no domain in which we are more demanding.
