A week in Ukraine - what to do? (Kyiv)

Going for the first time to Ukraine in June and except seeing two Euro Protected content in Kiev, Sweden-England (15th) and Sweden-France (19th) nothing is planned.
Do you have any good ideas in Kiev and other places?
Places I had in mind are e.g. Chernobyl, Odessa or Crimea.
Have in mind I don't speak any Ukranian.

Thanks,
Anders
