According to Die Atombombe und das Dritte Reich. Das Geheimnis des Dreiecks Arnstadt - Wechmar - Ohrdruf [The Atom Bomb and the Third Reich: The Secret of the Arnstadt - Wechmar - Ohrdruf Triangle, by Edgar Mayer and Thomas Mehner, Nazi Germany succeeded in causing a nuclear explosion at an army base in Thuringia on March 16, 1945. I haven't seen the book, so I have no idea what evidence the authors put forward.
