After the American deployment of nuclear weapons at the end of World War II, the Swedish military leadership recognized the need for nuclear weapons to be thoroughly investigated and researched to provide Sweden with the knowledge to defend itself from a nuclear attack.

With the mission to " make something with neutrons ", the Swedish team, with scientists like Rolf Maximilian Sievert, set out to research the subject and eventually build a nuclear reactor for testing.
