Electrical Design Changes at Indian Point No. 3 Nutclear Generating Station

This paper is intended to describe the Indian Point No. 3 electrical facility in general and some of the major electrical modifications made to the original plant design. These design changes involved modifications to the offsite power suppy system, the plant D.C. system, the diesel fuel oil transfer system and other hardware and circuitry within the "safeguard" system. It should be understood that many of the modifications came about during the later stages of plant construction. This, of course, limited the designers freedom in developing feasible solutions to various problems encountered.
