Washington DC: United States Department of the Interior, Defense Electric Power Administration, 1964. Presumed First Edition, First printing. Wraps. vi, 243, [3] pages. Maps (with some color), Tables, Figures. Notations on front cover and title page. Cover worn. RARE. This is the report of an engineering study on the vulnerability of the nation's electric power systems to attack by nuclear weapons. It was authorized by the Dept. of Defense, Office of Civil Defense and the Dept. of the Interior, Defense Electric Power Administration. The Office of Civil Defense, realizing the necessity of having essential ventilation and illumination in community shelters, sought a valid estimate of the electric power service that would be available under conditions following a nuclear attack. The results of this study were intended to provide the requisite estimate. It also contains useful information on the ability of the electric power industry to furnish power for decontamination and recovery during the survival period following the first 15 days of shelter confinement. The Defense Electric Power Administration was selected to perform this study because of its recent experience in conducting related studies. Representatives from more than 1500 operating companies contributed more than 50,000 person hours to obtain and analyze much of the technical information and supporting data for the material contained in this report. This study was the most complete analysis made to date (1964) of the effects of an assumed full-scale nuclear attack on the nation's electric power industry. These effects were examined in detail to find out what they mean to the entire electric power industry in terms of physical damage to the generating plants, transmission lines and related facilities.
