Type: Underground @-623m |
Yield: 5kt
France ceased atmospheric testing of nuclear weapons in 1974, with testing being conducted underground at Mururoa and Fangataufa. Deep shafts were drilled, the test devices were lowered then detonated deep below the atoll. These underground tests were far less polluting, but the process was more complex and therefore more expensive. As it turned out the porous nature of the coral meant that there was still significant leakage and contamination.
