In other words:
- no hydroelectric power plants (https://en.wikipedia.org/wiki/Dam_failure#List_of_major_dam_... );
( https://en.wikipedia.org/wiki/List_of_hydroelectric_power_st... );
- no chemical plants ( https://en.wikipedia.org/wiki/Category:Chemical_disasters );
- no refineries, petroleum processing ( https://en.wikipedia.org/wiki/List_of_oil_spills );
IMHO, nuclear plans are a good option to solve current energy needs and modern nuclear plans are safe even in worst case scenario in Ukraine I don't think a new Chernobyl disaster will be possible because that event was generated by events related to a chain of factors impossible to exist there.
I think the better way to avoid the risk of nuclear disaster in case of war is to renounce to atomic bombs and working to avoid proliferation of that kind of weapons.
