For whatever it's worth, Russia continues to operate several RBMK reactors today, and haven't blown any of them up since Chernobyl in the 80s. This is probably attributable to some combination of the retrofits they made after Chernobyl, generally treating the matter more seriously, and maybe luck.

Retrofits have not generally occurred. The person most personally responsible was given control of another one.

The retrofits did occur. The second sentence of your comment does not relate to the first; 'retrofit' does not mean "change in management"

We know at least some retrofits were done.
