Table 4.35 Land Requirements, by Technology, in km^ per GW of Installed Capacity Fuel cycle figures reflect the fact that LWR activities disrupt about one-eighth the land disrupted for coal technologies. For the remaining technologies, fuel cycle activities result in negligible land disruption. The land area needed for disposal of nuclear waste is negligible (less than 5% of that required for the plant). In the case of coal, fuel cycle activities at any point in time will have disrupted about four times as much land as that required for the plant, assuming that a 6-year land reclamation program has been successfully implemented. To obtain results in terms of land per unit energy output, the operating factor (accounting for availability, load factor, and insolation for TPV) must be specified. These factors, along with the land requirements in km^/ GW-yr, based on a 30-year life for each technology, are listed in Table 4.36. The operating factor for TPV represents an average figure for the two locations (Phoenix and Cleveland) considered in the technology characterizations. The results of Table 4.36 indicate that only one comparison changes: although SPS requires the most land on an installed-capacity basis, TPV requires the most land on the basis of energy output. One reason for this is the limited number of hours per day that insolation is available. Alternative Futures Comparison. Demand data have been listed in Tables 4.7 through 4.9 in Sec. 4.1. These data, plus the land requirements data in Table 4.35, can be used to estimate total land requirements. These results are shown for individual scenarios in Figs. 4.34 through 4.39. Figure 4.40 illustrates the overall land requirements for all scenarios. Table 4.36 Land Requirements per Unit Energy Output
