Analysis of Estimated Cost for Three Pacific Northwest Nuclear Power Plants

Three net-billed nuclear powerplants are now under construction in the State of Washington by the Washington Public Power Supply System (WPPSS). A comparison was made of the estimated annual power generation costs for the WPPSS plants to the estimated costs of a typical nuclear powerplant as defined in an Ebasco corporation study. Particular attention was given to assessing the assumptions used by WPPSS in calculating these power costs.
