Fig. 6.2-16. Utilization and Movement of Fissile Material in a Nuclear System
Consisting of LWRs Operating with Plutonium and/or Uranium Recycle (Case 2L, High-
Cost U308 supply) (Year 2035).
The effect of the intermediate-cost U308 supply on the LWR plutonium recycle case
is shown in Fig. 6.2-15. With 6.0 million ST U308 below $160/lb, the maximum nuclear
contribution would increase from approximately 600 GWe in the year 2020 to approximately
960 GWe in the year 2045. Thus, the U308 supply is again the dominant variable. The
maximum annual U308 requirement would be 110,000 ST/yr and the maximum annual enrichment
requirement would be 72 million SWU/yr. These annual requirements would constitute the
principal limitation of the system.
The utilization and movement of fissile material per GWe of installed capacity for
the LWR with plutonium recycle is shown in Fig. 6.2-16. Again this figure represents a
snapshot of the system in time (in the year 2035) and includes both the first core loading
for those reactors that are starting up and the last core discharge for those reactors that
are shutting down. The annual U308 consumption in 2035 is 59 ST U308/GWe, and the LWR
utilizing plutonium comprises 54% o f the installed capacity.
fissile plutonium in fresh fuel per GWe of installed capacity per year must be handled
within the energy centers for this case.
Approximately 368 kg of
(Note: Simply identifying the amount of
fissile plutonium in fresh fuel that must be handled is not analogous to determining the
diversion resistance of the system. While the amount of fissile plutonium being handled
may be important, the state and location of the fissile plutonium and the procedures used
to handle it are more important in assessing the diversion resistance of a system.)
