R.E. Chaney, S.G. Colt, R.A. Johnson, R.W. Wies, G.J. White - 2004 Dec 15: A comparison of electricity generation options for Galena, Alaska. Nuclear is the best. This report covers: - energy load profiles for Galena, - technologies and resources available - uses for any extra power - environmental and permitting issues, and - the economics of these energy options. Conclusions: The nuclear system will provide the lowest cost power. For environmental concerns the nuclear plant is a clear winner. Obtaining permits for the coal plant appears to be the most difficult. The assumption is that NRC approval will establish reasonable staffing levels. The coal option may be economic in some scenarios compared to enhanced diesel systems, so the coal option should not be entirely dismissed. Even though installation of the 4S nuclear plant presents a potential long-term solution to Galena's critical energy issues, other aspects, such as safety analyses, remain to be performed as part of the licensing process. Ultimately, the selection of the best energy option must consider these analyses and other factors. Specifically, regarding the 4S nuclear plant option, safety relating to potential accidents involving the reactor core and the use of liquid sodium as a heat transfer medium must be adequately addressed. If this technology is successfully deployed in Galena, its economic viability in other Alaska villages and elsewhere depends on the actual life cycle costs yet to be quantified. Benefits associated with adoption of one or more of the technologies discussed in this report go beyond their ability to meet Galena's immediate needs. There is potential for Galena to serve as a training center for rural Alaskans interested in using similar technologies in their villages. And there is potential for use of additional cogeneration leading to economic development such as horticulture and aquaculture.
