There was a reactor meltdown in 3 our of 4 buildings caused by a tsunami/earthquake.

You can read about the events on Wikipedia or whatever.

Huge amounts of soil and water were irradiated. Cleanup and Deconstruction will take around another 30years.

Please, Don't get me wrong.

The physics and engineering of nuclear power is awesome and one of humanity's greatest achievement.

I just think the risk/reward equation is completely off for many still running reactors.

Maintenance is a huge issue, spent fuel can't be recycled completely, new fuel rods are getting more expensive, the public often has to pay for decommissioning afterwards because of rigged, lobbied contracts.

-> It's not worth it.

As far as I know, there is currently no new and proven reactor design addressing these issues and also being non-expensive and time-consuming in construction.

Decentralized solar and wind power with adequate battery storage is the way
