HEALTH AND SAFETY The comparison of health and safety aspects of advanced and current technologies is not possible on the basis of total quantified risk because of the uncertainties and unquant ifiable impacts for all the technologies, even current coal and nuclear technologies. The health and safety issues can best be summarized as follows: • All the technologies will have distinct health and safety impacts. • It is difficult to quantify and assess the low-level and delayed impacts of all the technologies. Assessing the health and safety risks required three major tasks: detailed characterization of each phase of the fuel cycle; analysis of the magnitude of risk associated with each identified issue; and accumulation of risks by technology, risk category, and generation scenario. Each segment of the energy cycle was considered, including component fabrication, plant construction, fuel extraction and processing, operation and maintenance, and waste disposal. In addition, an uncertainty index was assigned to each issue to reflect the uncertainty in the magnitude of the impact. Figure 3 shows the total quantified construction and O&M fatalities per MW/yr for SPS and five alternative technologies. Fig. 3 Total Quantified Construction and O&M Fatalities per 1000 MW-yr
