On 22 April 1939, after hearing a colloquium paper by his colleague Wilhelm Hanle at the University of Göttingen proposing the use of uranium fission in an Uranmaschine (uranium machine, i.e., nuclear reactor), Georg Joos, along with Hanle, notified Wilhelm Dames, at the Reichserziehungsministerium (REM, Reich Ministry of Education), of potential military and economic applications of nuclear ...
Operation Epsilon was the codename of a program in which Allied forces near the end of World War II detained ten German scientists who were thought to have worked on Nazi Germany's nuclear program. The scientists were captured between May 1 and June 30, 1945, [ 1 ] as part of the Allied Alsos Mission , mainly as part of its Operation Big sweep ...
By November-December 1944, they had concluded that there was no threat of a German atomic bomb, and that the German nuclear program had only reached an experimental phase, not a production phase. After the defeat of Japan, an Alsos mission was sent in to evaluate its nuclear program as well.
1944. On March 19, Takeuchi Masa of the Japanese nuclear weapons program's Riken laboratory constructs the country's first Clusius tube thermal diffusion design for uranium enrichment. [34] In March, the 305 Test Pile begins operation at the Hanford Site, primarily to provide quality assurance of graphite for subsequent reactors. [35]
Werner Heisenberg, Director of the Kaiser Wilhelm Institute for Physics from 1942. The Haigerloch Research Reactor was a German nuclear reactor test facility. It was built in a rock cellar in Hohenzollerischen Lande Haigerloch early in 1945 as part of the German nuclear program during World War II.

The Soviet Alsos or Russian Alsos is the western codename for an operation that took place during 1945–1946 in Germany, Austria, and Czechoslovakia, in order to exploit German atomic related facilities, intellectual materials, material resources, and scientific personnel for the benefit of the Soviet atomic bomb project.
Under supervision of the SS, from 1944 to 1945, German scientists in Thuringia tested some form of "nuclear weapon", possibly a dirty bomb (for the differences between this and a standard fission weapon, see nuclear weapon design). Several hundred prisoners of war are alleged to have died as a result.
