Denmark yakanga ichigarwa navaGermany, iye akanga ane musangano wakakurumbira naHeisenberg, uyo akanga ava mukuru wepurojekiti yezvombo zvenyukireya yeGermany. Muna September 1943 mashoko akasvika kuna Bohr okuti akanga ava kuda kusungwa navaGermany, uye akatizira kuSweden. Kubva ipapo, akaendeswa kuBritain, uko akabatana nebasa reBritish Tube Alloys rokugadzira zvombo zvenyukireya, uye akanga ari nhengo yebasa reBritain kuManhattan Project. Pashure pehondo, Bohr akadaidzira kubatira pamwe kwamarudzi ose pasimba renyukireya.
