Fig. 4.43 O&M and Fuel Cycle Labor Requirements The annual construction labor force for SPS has been estimated at 2500 persons per installation. Assuming that construction takes place over two years and that the construction crew must stay at a single site for the entire time period, then the number of crews required (after the first year) would be one or two for scenario CI, two for scenario UI, and four for scenario UH. In scenario CI, the distribution of labor requirements from year to year is uneven due to the deployment rate of two systems every three years. The skills required are not identified in this analysis. However, they are likely to be much different between technologies (e.g., space construction workers for SPS); further treatment of these differences is beyond the scope of this analysis. 4.6 MACROECONOMIC AND SOCIOECONOMIC ISSUES 4.6.1 Introduction This section uses results from earlier sections on scenarios (Sec. 4.1) and cost and performance (Sec. 4.2). Results* of the macroeconomic analysis indicate that (1) if uranium and coal supplies are highly constrained, then the costs due to deployment of more *A11 cost figures in this section are in 1978 dollars.
