Operation Teapot Nevada Test Site February May 1955 Project 351 Effects Of Atomic Weapons On Electric Utilities

Duplicate electric-power installations consisting of transmission, substation, and distribution equipment were constructed in areas 4700 and 10,500 ft from Ground Zero (GZ) for use in Project 35.1 in the Apple II shot. The test was made to determine the median survival range of the electric equipment the extent of damage and the nature of the repairs required to restore disrupted service; and the ability of electric systems, in comparison to industrial plants and the residential communities they serve, to withstand the effects of an atomic explosion. The damage was confined to the transmission and distribution circuits at the 4700-ft area and was of such a nature that the equipment could have been easily and quickly repaired. In the same area, typical homes were completely destroyed.
