Operation Totem status, the British government restarted its own development effort, which was given the cover name "High Explosive Research". The first British atomic bomb was tested in Operation Hurricane at the Montebello Islands in Western Australia on 3 October 1952. The main purpose of the trial was to determine the acceptable limit on the amount of plutonium-240 which could be present in a bomb. The plutonium used in the original Hurricane device was produced in the nuclear reactor at Windscale, but the Windscale Piles did not have anything like the capacity to provide sufficient material for the British government's planned weapons
Nuclear weapons tests in Australia atomic tests at Emu Field in 1953 were known as Operation Totem The atomic tests at Maralinga in 1957 were known as Operation Antler A testing site at Maralinga was established in 1955, close to a siding along the Trans-Australian Railway. Because supplies could be brought to the site via rail, it was preferred over Emu Field. A total of seven major tests were conducted at Maralinga. Both the Federal government and Australian newspapers at the time were very supportive of the tests. In 1952, the Liberal Government passed legislation, the "Defence (Special Undertakings) Act 1952", which allowed the British
