==History==
The Udachnaya pipe diamond deposit was discovered in 1955. Due to its isolated location, it was not exploited until the 1960s. In conjunction with the beginnings of diamond production, the urban-type settlement of Udachny was founded in 1968; town status was granted to it in 1987.〔''Registry of the Administrative-Territorial Divisions of the Sakha Republic''〕
As part of a plan to create the basin for a tailings dam for the nearby diamond mine, a 1.7 kiloton atomic bomb was detonated underground near Udachny on October 2, 1974. Original plans had called for eight similar explosions to be conducted; however, due to radioactive fallout being far greater than expected, the project was halted after the first blast. The shaft in which the explosion was held was not plugged until eighteen years later, with an estimated thick concrete sarcophagus.〔(Report on the underground explosion near Udachny in 1974 and its status in 2000 ) 〕
