If you happen to be in the Stuttgart / Tübingen area of Germany, you should visit the experimental reactor in Haigerloch, now a museum [1]. You really get the impression that the team around Heisenberg was trying to build a reactor to generate energy, but you have to be careful: I am not sure that if they would've gotten to a state where a bomb was also feasible, they would've been openly (or even secretly) against building it. This quote by Heisenberg makes it seem like he thought about this quite a bit during his time at the Kaiser-Wilhelm-Institut, and maybe came to a personal conclusion: HEISENBERG: One can't say that. One could equally well say "That's the quickest way of ending the war.” [1] https://de.wikipedia.org/wiki/Forschungsreaktor_Haigerloch https://de.wikipedia.org/wiki/Forschungsreaktor_Haigerloch
