There is no Dukovany in Russia. The only Dukovany is in the Czech Republic, in Central Europe, not Poland! It is 871 miles to the northwest of Sevastopol, not directly north of it. It is also 73 miles south of Poland.

Mahilyow, Belarus is east of Dukovany, Czech Republic, not west. If anything, with respect to the Russian setup in Theater of War, Mahilyow should be on the right, Dukovany should be on the left.
