The annual consumption of U308 i n 2035 was found to be approximately 32 ST U308/GWe.
This consumption rate will decrease continuously as the 235U-10aded LWR is replaced with the
233U-loaded LWR.

Fig. 6.2-32. Utilization and Movement of Fissile Material in an LWR-FBR Nuclear
System with a Light "Pu-~o-~~~UI' Transmutation Rate (Case 6L, High-Cost U308 Supply)
(Year 2035).
In summary, a strategy based on an FBR with a Pu-U core and a thorium blanket could
supply a net addition rate of 15 GWe/yr to the year 2050 and beyond with a U308 supply of
3 million ST below $160/lb. The installed nuclear capacity in 2050 would be 1100 GWe,
with 560 GWe, or approximately 50% of the installed capacity, located in secure energy
centers. Approximately 27% o f the fabrication capacity must be capable of handling fuel
containing 232U. Thus, while a nuclear system based on an FBR with a Pu-U core and a
thorium blanket can supply 15 GWe/yr for an indefinite period of time, it simultaneously
requires that a significant amount of nuclear capacity be located in secure regions.
