A description and evaluation of Project Sedan, part of the Atomic Energy Commission's Operation Plowshare. Plowshare sought to promote the use of nuclear weapons for peaceful purposes. In the Sedan shot, a buried 100-kiloton thermonuclear device was detonated to test the use of nuclear explosives to quickly excavate large amounts of earth and rock. The resulting explosion created a crater 1,200 feet across and 320 feet deep, and a cloud of radioactive dust.
