Figure 7.29 Evolution of world carbon-dioxide emission rate, integrated emissions, total atmospheric accumulations (Hasselmann et al., 1995), and estimated global average temperature rise (Hasselmann et al., 1995) for the BAU/BO basis scenario

(Krakowski,1999).

this scenario signature changes when the once-through fuel cycles fMOX = 0.0) for the otherwise BAU/BO basis scenario is considered. It is noted that the OT/LWR fuel cycle projects a somewhat lower cost of energy than for the/MOX = 0.3 BAU/BO basis scenario, so that the OT/LWR scenario gains a slightly greater market share; AT in the year 2095 is thereby somewhat reduced, while the PRI is reduced by ~14% because of the reduction of (more heavily weighted) separated plutonium.

7.5.3 Sample results: capital cost variations

In searching for economic drivers needed to obtain a model-determined phase out of nuclear energy without the imposition of a carbon tax (e.g., the BAU/PO scenario), a programmed increase in the unit total cost for nuclear energy, UTC($/We), by a factor of /UTC was exogenously imposed in the ERB model. The results of this parametric study are summarized in Fig. 7.32, which also includes comparisons made with the recent IAEA study (Wagner, 1997);
