| has gloss | eng: Greenhouse Item was an American nuclear test conducted on May 25, 1951 as part of Operation Greenhouse at the Pacific Proving Ground, specifically on the island of Engebi in the Enewetak Atoll. The shot was the first test of a boosted fission weapon, where deuterium-tritium (D-T) gas injected into the enriched uranium core of a fission weapon. The fissioning weapon produced nuclear fusion reactions with the D-T gas (not enough to be considered a full fusion weapon, though), which generated a large number of neutrons, greatly increasing the efficiency of the nuclear fission reaction. The yield was 45.5 kilotons, around twice the yield of the unboosted primary. |
